Ending the era of politics of scarcity

There is a stark difference between the economical foundations of capitalism and that of Marxism (which is to say socialism, communism, progressivism and modern day liberalism) and that difference in foundation is rooted in the view of individuals.  Within the capitalist system individuals are seen as actors in the economy, they have the ability to deal with each other under a common set of laws that are applied equally and upheld for contracts.  This is not 'pure' capitalism, but one that is formulated under the Law of Nations which provides the social context for delineations between the individual, the State (which is to say the governmental system of laws) and the Nation.  It is a system that can easily be corrupted by the State in the Name of the Nation (Nationalization) which leads to impoverishment of individuals who are then targeted by State laws so as to drive them out of business in favor of the State.  Further the business sectors that are Nationalized are then under no impetus to improve the type, quality, nor amount of goods and services they produce as their business model is completely under control of the State.  Typically this sort of corrupt capitalism is seen in modern day China, Russia, Iran, France, UK, Argentina and anywhere a business sector has been Nationalized either in name (directly via law) or indirectly by a form of State based mandates, price controls, and limitations on individual choices to conform to a State set of laws that restricts decisions on price optimization or goods provider. 

Another formulation of corrupt capitalism is crony capitalism in which business sectors get in bed with politicians of any stripe to get preferential treatment under the law and taxpayer subsidies.  This form of corrupt capitalism is a variant of State owned corrupt capitalism as it seeks to use State power to create divisions amongst companies in a given sector, reward those that follow government strictures and punish those that do not.  It is a form of control that ends, however, at the same point as horrifically inefficient capitalist companies survive because of government aid and intervention yielding the same restricted marketplace, the same high costs and the same lack of incentives to do well that a directly government controlled or Nationalized set of companies.  Crony capitalism is corrupt capitalism of the direct sort seeking only indirection to persuade people of a Nation that overt and covert regulation is good for them while it is, in fact, good for those companies that play ball with politicization and then utilize corporate money (enhanced by government subsidies) to back politicians.  That interim period gives a patina to the longer-term government control and rewards actors who invest in political ends through the means of regulatory schemes. No matter the means of corrupt capitalism, its ends are the same as Nationalized corrupt capitalism.  Any business that gets 'regulated' then has an interest in changing such regulation via politics, and in this arena the larger amounts of cash are held by the larger companies that are also less efficient due to their very size and overhead.

Marxism is a form of collectivism in which the individual is seen as a dependent actor that is not able (or allowed) to operate outside of a collective based economic view of capitalism.  This world view posits that humans are unable to cope or compete with the legal systems that allow corporations many of the same set of rights as individuals.  A corporation is seen as stronger, wealthier and more exploitative of individuals and those individuals then fall into classes: owners of businesses, the bourgeoisie (small business owners and the middle class) and the proletariat (working class).  This division by classes is seen as imposed by the top (the business owners) upon the rest of society and the bourgeoisie is seen as a 'rump' class in that it is barely more numerous than the owning class of corporations and barely more prosperous than the working class.  In this world view individuals in the proletariat are seen as a collective of individuals in that they are not able to have access to the bourgeois lifestyle and can take no meaningful part in the business ownership realm.  Capitalism is seen as corrupt and requires a proletarian uprising to get rid of the private ownership of business and collectively own all means of production by the State.

Do note that the end-state of corrupt capitalism and Marxism are little different: State ownership of the means of production (either major business sectors under corrupt capitalist schemes or complete ownership under Marxist schemes), which is run by an elite class via the State.  That elite class is either the corrupt politicians in the capitalist system or 'The Party' leaders in the Marxist view, both with a patina of 'democracy' that delimits choices for the mass of the population (usually well over 95%) to those few that are dictated by the elite.

There are stark problems with State ownership, however, as it has no need to be 'liberal' in the old school sense of teaching people to read, write, and think for themselves so as to be inventive.  All incentive and rewards to be better at one's job, to find new ways to do work, to develop new products to sell to help better the life of the common man are all crushed under the requirement of the State to have a workforce that enriches the tiny minority at the top and leaves the majority without the thinking capability to protest or say that there must be a better way.  This process of indoctrination and elimination of those who refuse to conform to the new State based edicts (be they in a corrupt capitalist system or a Marxist system)  is the movement from an authoritarian government to a totalitarian one.  Authoritarian States can still tolerate some work done outside of State control, although that is heavily controlled it is not extinguished.  Thus religion exists outside of the authoritarian State as well as some things like music and art.  Moving to a totalitarian State means that nothing is left outside the State's purview and every part of life must conform to State based edicts.  These latter systems are noted as being tyrannical, repressive and requiring large levels of internal repressions and external distractions to keep the population under control.  This final phase of totalitarian State is known as the Imperial State as it must be expansionistic to distract of the lack of living standards inside the State and to utilize the few bonds of Nationalism to create support for the State.  When the State cannot do this latter, it must start to give away much of its wealth in order to stay in control via entertainment and social services so as to mollify a population that sees the State as no longer doing its duty towards society, as a whole.  In both corrupt capitalist, Marxist and ancient regimes the giveaways start early in the process: 'land reform', redistribution of wealth, social services and entertainment are all venues for these forms of systems to distract and mollify the population.

When this process is performed there is a problem in State ownership (either the regulatory process of corrupt capitalism dictating what businesses can do or the take over in a Marxist system) because there are no real custodians of property to look out for it and maintain it.  Sociologically, this becomes known as 'The Tragedy of the Commons': when property rights are seen as not being held or able to be utilized by those directly involved in business, then there is no basis of stewardship for it.  Communally held land (or collectivized land) is over-utilized for grazing or crops because no individual sees a requirement to maintain it for the community, which lowers the productivity of the land for everyone. In an industrialized system this extends to quality of workmanship, timeliness of work and amount of work, which yields scarce and sub-par products in an insufficient amount to be distributed to those who need it.  The joke in the old USSR was 'we pretend to work and they pretend to pay us': there is no direct ownership of the process or the product and working that can be avoided is avoided.  This happens in a corrupt capitalist system when stewardship is so controlled by the owner of a business or property that they feel they have little say in its use, as well.  These are functional equivalents of State control and State ownership via law and regulation between corrupt capitalism and Marxism.

Marxists will always point to the requirement for a suitably industrialized basis for there to be socialism-communism, but no follow up is ever done on why people would want to actually work with no incentive other than altruism.  Altruism comes from prosperity and seeking to make the lives of others better in a material or moral way through the process of contributing to their welfare via a sense of charity.  There is no incentive in either the end-state corrupt capitalist or Marxist system for altruism to exist as there is no way to better one's fellow man's position as there is no prosperity and no means to perform charity that has any meaningful impact on the lives of anyone.  From this Marxism and corrupt capitalism both fail because of the leveling effect of production and distribution: when all get equally no matter how much work they do, the incentive to work declines and so does the living standard of not just the mass of the population but of the elites as well, albeit more slowly.

There is a common predicate to the way that corrupt capitalism and Marxism are sold, however, and it is an unstated one as a predicate, but one that is stated as part of the world-view of those involved in promoting them.  This common predicate is telling because it is used by both corrupt capitalist elites and Marxists to push their views forward and it is the same predicate for both: that goods and raw materials are scarce, the economy is a set size and that this requires a 'fair' division of goods due to scarcity of them.  This is the politics of scarcity, and it is telling that whenever one hears discussion of economic classes (or any other form of internal division amongst society, come to think of it) it is always couched in the terms of those who 'have' and those who 'have not'.  This language can be couched in terms of pay, living standards, or 'rights' and yet it is always the same world view of scarcity: there are not enough of these things to go around.  And yes, those who push this mean your rights that are born with you as not having enough of them to go around.  If it weren't for this being a political outlook, it would be classed as a psychological derangement. But I digress.

What is amazing is that the last two centuries of industrialization, post-industrialization and the rise of modern communications have created ever expanding economic systems which have raised the physical welfare of large sections of humanity out of abject poverty, lowered the cost to do so, and continually pushes the cost of production down so that the number of people able to afford products can increase.  Even under a system of slowly worsening of corruption of capitalism, the basis for capitalism demonstrates that it does more to provide goods and services to more people at a lower cost than any other system devised.  The attraction to control such spread of wealth and material well being is too enticing to those wishing power over their fellow man, and the only way to get this system corrupted is to convince enough people that it is biased, concentrates wealth and needs to be controlled by State power.

Are there abuses in capitalism?  Yes, undoubtedly.

Are they particular to capitalism?  No, they are part of human nature, as abuses can be seen in any human institution ranging from religious organizations to political organizations and everything in-between.  Man cannot get away from the desire to utilize power against his fellow man without the agreed-upon restrictions necessary to form society.  The agreement between individuals on self-governance and self-restriction also forms the basis for the codification of those things to create an organ of society to enforce them: government.  Marriage forms the basis for the Nation, and that self-made Nation comes from the family and our agreement to stay our negative liberties and rights towards our offspring, save as needed for minor and necessary correctives on their understanding of self-governance and why it is necessary.  Amongst families we create society and, from that, the need for the State via government, and it is this need for agreement upon set standards enforcement for all individuals that creates a system for laws that can be equally administered for all.  Corruption can and does start at this very lowest level, that of the individual agreeing that State power is to be equally administered and it is this point that is utilized by politicians who wish to further corrupt the economic system that is overseen (but not controlled) by laws.

The ability of politicians and their backers to convince people that there is scarcity, that someone having something means that they cannot have it (or an equivalent) is based on envy and greed.  Yet capitalism has been about increasing wealth, increasing the amount of goods, and lowering costs so that, today, being poor in the US doesn't mean you have outdoor plumbing and one pair of shoes, but can afford a refrigerator, washer, dryer, television, microwave, cellphone, and that sweet pair of Nikes that cost $150.  And still get overweight due to the cheapness of food.  By any objective standard of all of mankind's history, the poor in the modern industrialized world are living like royalty and the main threat to that prosperity and material wealth is cronyism that seeks to deprive you of it.  The trick is not to those pointing out to the disparity between a poor man with an old rust bucket Ford against a relatively well off person with a BMW roadster, but to point out that the person with the roadster is trying to convince the person with the Ford to vote for a politician that will hand more perks and carve-outs to the person with the BMW, at the expense of tax dollars.  If you want greater disparity between rich and poor, then vote for those trying to 'equalize' the system so that everyone can be made poor.  If you want to get out of the mess, vote for the person seeking to cut out all the biases and advantages due to ANY class or ownership division so that everyone is liable for their own actions and everyone must pay into the maintenance of government which is a benefit to ALL in the Nation.

This article is entitled 'Ending the era of politics of scarcity' and the reason I entitled it that is that there is another way to free up the system of scarcity politics that has little to do with politics.

Growing up in the 1970's meant many things, and as a reader of SF and Fantasy it also meant understanding the drivers behind things like space exploration.  Prior to modern economic analysis, it was hard to make a case for why space exploration is viable, other than it being a frontier arrangement promising much if you worked to keep yourself alive.  One book came out from Gerard K. O'neill called The High Frontier, which was a culmination of work done in Princeton in the late 1960's and early 1970's analyzing the utilization of space materials for space based industry.  Systemically the work is used to look at space colonization, but that is a byproduct of space industrialization.  Looking at space materials as resources that can be owned, utilized and put into a manufacturing system yields up a system that is well suited to capitalism and is actually a destroyer of the economics of scarcity for tens if not hundreds of generations and, possibly, forever.  This is not due to altruism or having items being 'the property of all mankind', which is a meaningless phrase, but due to the fact that things like moons, moonlets, asteroids and comets are akin to islands in an ocean and islands can be found, explored, inhabited and have their resources utilized.  What that means is that uninhabited resources can be claimed, owned and become something that will gain a steward for it so that it is utilized to the best interests of the steward.

The greatest resource base for the planet Earth's population is its Moon.  Once you can get past the gravitational hold of the Earth-Moon system the next closest things (by energy use, not distance) are asteroids as they have little gravity and can be exploited for productive purposes with minimal energy (financial and energy) costs.  This is an open-ended system, by and large, and while some things may be in short supply, that is only a signal for someone to find and bring back more of it, not to ration it or use it as a political football for, as soon as you do, then an even higher premium is put on that material and you will get independent actors seeking it in greater number.  Do remember that the Nation is based on the family, the State based in society, and that those who place down on an asteroid, create it into hospitable living space, and then inhabit it are then qualified to be their own Nation and have their own State.  That is all it takes to do this: fine uninhabited land, make habitation on it, declare the Nation and create the State to run it.  That is how it works on Earth and the vacuum of space can have no owners just as the free seas cannot, either.

Corrupt capitalism and Marxism both play upon scarcity and State power and require that there is no real way for individuals to escape the grasp of the State.  Usually there are death threats involved at some point.  Space is a great leveler between the individual and the State as, to keep everyone alive, everyone must agree to running it, even when there is private property everyone loses if there is one person who seeks to kill them by interrupting the system that keeps everyone alive.  Exercising police power in space is fraught with much more danger to the enforcers, as well as those it is enforced upon, with ultimate and terminal consequences for its misuse to all.  You cannot be both authoritarian and drive down basic education to political dogma as it gets you killed.  Not indirectly, mind you, but directly as the very incompetence that politicized politics inculcates is also its doom in a direct fashion as there is no ready biosphere to fall back upon to get a 'dark age'.  The dark of space is absolute, ultimate and terminal in short order.

Beyond the SF community, energy sector, and general non-crony capitalists who aren't State controlled, who else is a backer of space exploration for the good of mankind?

You would think that, by their anti-pollution rhetoric, that environmentalists would fit that bill.

Why?

It moves energy gathering and industries out of the biosphere both reducing pollution, increasing productivity and utilizing solar fusion power without the wasteful intermediary of an atmosphere and slowly rotating planetary mass which limits the amount of sunshine you can gather.  Earth based solar energy has high overhead, low amounts of energy per square meter, and high costs to produce (both energy-wise and in raw materials as silica requires high heat to be reformed into something useful).  If you know or are an environmentalist, then space exploration is a touchstone issue: if you claim no harm to your fellow man and just want a cleaner environment, then space exploration will yield that as a long-term end.  The same is with planetary bound nuclear power from Gen III and Gen IV reactor types that are inherently safe by design.  Any environmentalist that is not pro-space or pro-nuclear is one that is seeking government control over energy resources and industry with its high overhead and concentration of power in the political realm via the State.  To put it bluntly: environmentalists who seek huge regulatory schemes to control the energy sector and industry are Marxists or corrupt/crony capitalists.  The goal of reducing pollution of all sorts is one that should be over-riding to all environmentalists and it should drive to the conclusion that the most efficient means of production with the lowest overhead cost and greatest yield for human freedom is space exploration done by corporations and individuals.

Who else should be in the pro-space movement?  The high tech sector.

Why?

Space resources offer low overhead, low cost to gather raw materials on a scale unheard of at any point in Earth's history for anything.  And not just silica and rare earth elements used for semi-conductors, but iron, nickel, platinum, iridium, helium-3 (produced by the sun and a good resource for fusion), water, oxygen, nitrogen, carbon... not just the building blocks of industry but via asteroids with high light element content with CHON, the building blocks of life itself.  Everything that is necessary to not just create a remotely operated vehicle system for mining and exploration, but to build the necessary human habitations is cheaply available once you get to orbit.  A system of lunar materials gathering with mass driver to send materials into Earth orbit to be utilized by a set of refineries that would capture all of the materials from the lunar regolith would then yield all the necessary materials for life and to build more refineries and the first space factory.  The input cost is an orbiting refinery to melt regolith and capture materials and a small scale factory to fashion new parts.  New parts that can be for a human habitation.  New parts for a solar collection system to beam low energy density to a rectenna array on Earth for low cost solar power.  New parts for a new refinery.  New parts for another mining system.  New parts for another and larger factory.  All of it run on solar power directly from the sun as that includes heat that can be simply concentrated by mirrors as thin as a sheet of mylar to do the melting of lunar materials.

Environmentalists are proving out not to be backers of cleaning up the environment but of controlling mankind via government, by and large.  No one can point to an environmentalist space movement.

You can, however, point to a high tech space movement.

Blue Origin started up by Jeff Bezos, founder of Amazon.com.

SpaceX formed up by Elon Musk of Paypal.

Scaled Composites formed up by Burt Rutan pioneer of aviation and avionics for long-term sustained flight working with Virgin Galactic founded by Sir Richard Branson founder of Virgin Atlantic, Virgin Records and Virgin Megastores.

Armadillo Aerospace with John Carmack software game designer.

Space Adventures started up by Eric C. Anderson of Analytic Graphics.

To name a few.  Of most interest is the next one, Planetary Resources in which Eric C. Anderson is a co-founder as they have established themselves with a press release that starts out with the following:

Seattle, Wash. – April 24, 2012 Planetary Resources, Inc. announced today its plan to mine Near-Earth Asteroids (NEAs) for raw materials, ranging from water to precious metals. Through the development of cost-effective exploration technologies, the company is poised to initiate prospecting missions targeting resource-rich asteroids that are easily accessible.

Resource extraction from asteroids will deliver multiple benefits to humanity and grow to be valued at tens of billions of dollars annually. The effort will tap into the high concentration of precious metals found on asteroids and provide a sustainable supply to the ever-growing population on Earth.

A single 500-meter platinum-rich asteroid contains the equivalent of all the Platinum Group Metals mined in history. “Many of the scarce metals and minerals on Earth are in near-infinite quantities in space. As access to these materials increases, not only will the cost of everything from microelectronics to energy storage be reduced, but new applications for these abundant elements will result in important and novel applications,” said Peter H. Diamandis, M.D., Co-Founder and Co-Chairman, Planetary Resources, Inc.

In the midst of our economic doldrums started and perpetuated by the move towards the regulatory State, the stepping stone between capitalism and Marxism, the death-knell of Marxism is being clearly proposed.

Space exploration is that death as it offers the pathway to the most efficient means to create a new platform for humanity that is unlimited in scope and impossible to control via the regulatory State.

It offers the way forward towards demolishing scarcity economics by offering the pathway towards cheap and affordable energy, the lowering of the cost per item for hardened electronics (electronics immune to EMP and CME as that is a pre-requisite for space flight), and a way to uplift all of mankind's material wealth at the lowest possible cost to the greatest possible benefit.  Will some people get enormously rich from this?  I damned well hope so!  For if you thought the modern age of micro-electronics has expanded the cellphone out to the Bushmen of the Kalihari as a neat thing, just wait to you see what happens when this is done for energy production, distribution, and goods production on a solar system scale.

Marxism is all about scarcity, power and control concentrated into the hands of the very few elites.

Capitalism is about freedom, unlimited boundaries, and making things to benefit the greatest number at the lowest cost so you can sell a lot of it.

Space Capitalism is the future of mankind.

Because Marxism is its death and I think a good whiff of the grave it has intended for all of humanity will be sobering enough to force us to step away from it not just for ourselves but our children.

Got a debt greater than all the economies of the planet, combined?

Want a way to pay it off?

Then its time to get more resources flowing into the economy than the entire planet has, now, isn't it?

It's either that or death.

Unbounded freedom for all with everyone picking up their part of the workload and profiting from their liberty.

Or tyranny leading to the extinguishment of mankind as a species via Marxism.

Its a scary universe out there.

But nothing so scary as the grave of tyrannical utopia.

The choice is yours.

Best choose quickly as your time and life are running very short now and the choice between the stars of forever or the bars of final imprisonment for all of mankind is your choice to make.  The future can be yours and freedom for mankind perpetual if you dare to grasp it. 

The way forward is already mapped out by Gerard K. O'neill, the hard work is left up to us.

First you get chronic illnesses...

...and then you get sick.

I am lucky in that the number of upper respiratory tract infections that I get have dropped from their extreme high in my teen years (anywhere from 3 to 5 per year with some of them lasting nearly a month) to merely 1 or 2 a year.  No matter how well I take care of myself, I still get the bugs... but taking good care of my diabetes allows me to track when something is trying to get a jumping off point and deal with it.  I may get a 3 day stint of relatively high readings and then my body will have gotten rid of the germ and I'm right as rain.

Still, once or twice a year I get something that isn't so easy to shake and I have one of those now.  I would well and truly not have survived my teen years without modern medicine circa post-1940.  One or two sulfa drugs I can stand but they never dealt with the infections I've gotten in the upper respiratory tract.  That is the ears, sinus, throat and, when things get really bad, the upper parts of the lungs although that hasn't happened since I was 16.

I can't really do much of anything safely with tools of any sort, although that doesn't mean I can't find things to do or things find their way to me.

My lady's laptop, a Dell Inspiron 1721 bought a few months after mine, decided that its problems with the battery system (that is it hasn't been recharging them properly) now needed to have a hard disc problem.  As I had been looking a bit deeper at the recharge problem and realized that it wasn't the batteries or the software, that meant that it was the hardware which is on the main board of the system.  Here is what I do when I see a major problem on the motherboard of a system that is over 5 years old: I get a replacement and build a new system.  I can't do that with a laptop and had to buy a replacement and decided on one of the HP Pavilion line of computers... refurbished, natch.

The Inspiron finally coughed up a major problem on the hard drive and it took half an hour just to boot enough of a system to see the drive errors that filled the error log.  Since I had already gotten the major apps installed on the HP, plus removed a bit of the built-in cruft (although I never got to removing all the games and other junk that came with it, but it sits quiescent, unused and, therefore, relatively safe) put in my favored AV (Avast!) and the Comodo free firewall, it was ready for use.  The first order of business was to take a look at the drive from the Inspiron on another computer, which would require that I get the actual hardware to do that, a USB to SATA/IDE drive connector.  Since I was doing that at NewEgg I also got a new drive for the system and scared up some freeware to copy a drive image if I could find it.  Those both arrived just as I was starting to get sick...fun, fun, fun!

A day after it arrived I put the old drive onto a system and did a basic scan, which didn't show much.  Then I took an image of the drive, and put an image of that on the new drive.  That drive wouldn't boot.  Thus I had to scare up a Live CD to see what was going on and that finally revealed that the drive wasn't being properly recognized by the system.  I put on an MBR and still, no dice.  Pull the new drive with image and then put a really nasty chkdsk /f on it.  An hour later... it was bad news for the old drive image.  The second chkdsk /f only took about 10 minutes revealing no other problems.  For S&G's I put it in the system and no boot, of course.  Two directories held massive amounts of recovered files, all unusable.  Thus it was time to pull out the old install DVD and get to work...

The new drive is functional and happy, the old image is mostly awful and unrecoverable, and yesterday I spent most of the day hunting down drivers, apps, and generally getting enough on the Inspiron to get it past the bootable stage and close to useful.  I slapped an AV on it and still have to put on another firewall, and then have to do a final clean-up, defrag and general getting it back into functional order and examine any NEW errors coming up.  Both of the Dell laptops are the same vintage and I'm guessing some minor thing like, oh, a cosmic ray toasted out part of the old hard drive on the machine I was working on.  A thorough low-level disc scan and sector map should figure that out and would make the difference between having a drive that had some minor but critical event and one that is wholly unreliable.  Since there are no cables I can easily get at involved, if its the cables then I'm to stripping the system apart and if I have to do that I will see if I can scare up a new motherboard from that old line of Inspirons.  Basically, by the time you put in the cost and effort to get an old machine up and running, you are at the cost of a low-end refurbished machine that will do more.

Until the economy truly tanks when we are seen as an unreliable spendthrift.

All bets are off, then.

I can do a lot more than just woodworking... a bit of firearms work... geology...

Actually it seems as if my interest in a lot of subjects has some dividend to it.

Another project I'm taking up... where do I get these ideas, anyways?... is an adsorption cooling system/refrigerator.

Basically most refrigerators around your house run on electricity and have a compressor involved.  Those running on propane or other fuels have a burner to heat up a liquid to its vapor point and then evaporating coils to get the vapor to phase change back to a liquid (thus cooling what it is in contact with) and then a final condensation set of coils to make sure the liquid gets back safe and sound to the heater.  You can make that into a solar system, and efficiencies vary.  These ones with minimal to no compressors are absorption systems.

What an adsorption system does, in contrast, is uses a medium to temporarily bind the vaporizing medium to the surface of it as a liquid.  That surface, when heated, breaks the weak surface attraction bonds and creates a vapor that then goes away from the region being heated.  Cooler areas will draw off heat to start and then, since the liquid is barely in a vapor state, the vapor condenses and removes heat from the area.  Since it is a phase change it takes more heat away than it puts in, thus chilling the area down.  This is a chiller, not a real refrigerator, but gets to much of the same ends.  The physics is pretty old, going back to Van der Walls force and the equations that govern this attraction between gases and liquids when they are in relation to surfaces.  It was not applied to chillers until... I think it was 2003 or 04 by Toshiba.  Amazing how 19th century physics can still be used today, isn't it?

Doing a bit of reading up on the subject the main elements for a solar chiller consist of a liquid that easily turns into vapor at a relatively low temp, an adsorption media that can attract a lot of molecules to its surface, a heating chamber with the materials in it, and a cooling area.  That is it, no pump.  Nature does the work both at the chiller area and, when the sun goes down, the liquid and vapor go back to the cooling region with the adsorption material due to the attractive force it has on its surface.

That's the theory, at least.

So what are the actual materials?

Methanol and activated carbon.

Methanol you can get from various sources, but you want it anhydrous.  Anyone doing biodiesel can point you to suppliers.

And activated carbon?  Used for filtering fish tanks.  Get it in the spherical, low dust version as you don't want carbon dust clogging the thing up over the years.  Some fine screening might be a good plus for the system.

I've ordered the basics for a rig to test it out:

- A length of 2" black pipe, 24" long with couplers and bushings to get the ends down to 1/2".

- Copper pipe in 1/4" for the chilling/condensing region

- Copper pipe in 3/8" for the heating to chilling region, thus giving the vapor a slightly easier path up to the 3/8" to 1/4" reducer

- Brass pipe fittings to mate all this up, I have teflon pipe tape

- Plastic boxes used for scrapbook making, which I will fill with brine and use bulkhead 1/4" connectors for, and this will be the chilling region... I may need to put a minor coating of something on the copper pipe, like shellac, say... dunno

Still to be made are a simple stand to hold the rig in place, and a couple of cardboard boxes so I can test the thing out.

For a simple test the black pipe gets mounted on black painted wood, perhaps in an open box configuration to help concentrate the heat, the copper runs up the sides to a platform with a brine filled box, and the 1/4" pipe has some gentle bends coming out of them (and some tighter ones inside the brine containers) to serve as condensers and a simple bend pipe trap to allow liquid to serve as a barrier to any back pressure coming from the heating area so the flow goes in one direction.

I am not expecting more than a few degrees difference between the box with brine and pipe and the box that will just have a brine container without pipe.  A couple of sunny and dry days will help this out no end once it is built.  If I can get any results then I will have the known factors for materials, sizing, volume and so on to allow for scaling up of things.  I'm figuring more heating chambers in a flat box with glazed glass over it, and a top and bottom vent to allow hot air to move slowly out of the system will be a final design goal.

That and an old refrigerator I can strip out and put in some better insulation to help things along.

In theory this all works, although size and scaling is unknown.

Getting to the practice part is the hard part... but even a small chilling box that keeps a constant temp for medications and other such items would be great to have.  Plus it is no maintenance once it is put together with a sturdy frame and always works so long as there is any sunshine at all.  Weatherizing it may take a bit, but that is another bridge to blow up when I come to it.

Just because I'm sick doesn't mean I'm out of it.

Operations just shift venues for awhile.

Solar Energy to Fuel Cell, welcome to your new lifestyle!

Update: Thank you, Victor! This article has been reworked with the section of my bad math now marked and after calculations done on the right math...

Fascinating stuff on the energy front with a MIT researchers David Nocera and Henry Dreyfus finding a new catalytic system for changing water into its constituent components: oxygen and hydrogen gas. This is, actually, excellent news, but trying to go beyond that to linking this with solar cells and other energy sources. This, by their diagram, is an electricity based system, not one depending on photons to do the work, as is seen in their diagram here:

oxygen-graphic-1

So, this utilizes the efficiency of solar panels, currently hitting around 15% of incoming sunlight, to split water and hold the gases in storage until needed later. Not only do you become your own power plant, as Prof. Nocera points out, but you also become your own hazardous gas storage area, too! Hazardous?

The hydrogen actually isn't the bad part of this system, really, although it can be quite energetic which I will get to later, but it is the oxygen. Pure, life giving oxygen does something else which is known as 'oxidize' materials. If you light a candle you are oxidizing wax via the flame to get heat, thus changing hydrocarbons into various forms of carbon (dioxide, monoxide) and some water generated by liberated hydrogen and free oxygen in the air. Pure oxygen is damned dangerous stuff around an open flame or even spark source and creates lovely, high activity oxidation reactions when ignited. What the system is leaving out is that you, to get the energy on the cheap, will need to have excess energy unused during the day to have hydrogen and oxygen you use at night to get energy out.

Then there are the pumps... pumps? Well, if you have water pressure from a distribution facility (known by many as 'main water' or even 'city water') that is taken care of for you by the pumping facility and I won't consider it in this set-up. But if you get water from your own underground source, then pumping it up to the surface and pressurizing it is a non-zero energy input to the system. The pumps, here, would be those to pressurize hydrogen and oxygen into the tanks so you don't have huge low pressure tanks to put the stuff in which would take up more space than your home has. There are non-liquid storage systems for hydrogen, namely putting it into a reversible chemical reaction with a metallic sub-strate, but that gets you constant pressure hydrogen in which the substrate releases hydrogen as pressure drops, thus maintaining a constant pressure. Neat stuff, still needs a pump. Oxygen, in theory, you could vent out into the atmosphere and then just use an atmospheric intake for reversing the procedure later. Worth examining as it eliminates the really nasty part of the system from your house, although one hopes it doesn't become a 'ticking time bomb' of a gas jet ready to ignite next to your home if this option is taken. Probably would need some pre-mix with outside air via expanded tubing and air intakes to get some of the less oxidizing parts of the air in with it before exhaust. A mere technicality.

The first part of this is the kicker, and, really, getting a greater efficiency on the solar panel side with a cheap system would be great. Even Nanosolar has problems getting to that 15% and higher purity materials cost much, much more, but they make it up in low cost per square foot of production via printing techniques and presses. As I have looked at energy quite a few times and have a post up that does a bit of an overview, I will link to that and use some of the materials from previous posts to get some of the numbers. When looking at the electricity for vehicles, just to replace automotive gasoline (not diesel or aviation gas) I came up with 1.08E+12 kWh/yr, considering energy delivered to the vehicle equivalent after removing the inefficiencies of the internal combustion engine and considering in only an 85% transfer rate for storage in the vehicles (or 15% energy lost via transmission, storage, etc.). That would replace the gasoline used in 2002 I believe it was, which was 125 billion gallons. Electricity is a very good way to run a vehicle as it depends on much higher efficiency electric motors to deliver power rather than a relatively low efficiency internal combustion engine. The problem is: storing the energy.

Let me make a push for high temperature and capacity superconductors, as those would fit the bill *perfectly*. A loop of thousands or tens of thousands of strands of that sort of material would do the trick at, presumably, lower weight and near perfect efficiency. We aren't there, yet, although recent advances have gotten us to dry ice temps for superconductive materials. Ok, push given for near 100% efficiency!

[The following section is incorrect due to my poor math skills]

So lets start flipping the numbers around and see what this means on a personal scale. I will do the quick step here, but I do have links to back the numbers at the previous article:

1) Average insolation in the lower 48 is 4 kWh/sq. m./month. The tropics are pretty steady at 5 kWh/sqm/month while going northward sees higher seasonal variations. Basically, there is a lot of energy coming down through the atmosphere, although nothing like the pure stuff in the vacuum of space. If you want *real* energy, that is the place to go and to get outside the atmosphere. Diurnal frequency (variations for non-producing hours, taken into account with the above.

2) Average household energy use. Now this one gets a bevy of conflicting numbers as many divide up the energy into different types, like Underwriters Laboratories does and I will harvest a couple of numbers from them -

Annual household lighting use: 2,100 kilowatts/hour (kwh)

Annual household electricity use: 10,660 kwh / household

Of which the second is the one needed. Now this is across all families, all places, all times, etc. and isn't the cyclic energy used per day with seasonal variations. But as a starting point it gives an idea of the amount of energy the system needs to capture overall - 10,660 kWh/yr. or, divide by 12, and I will round up a bit to the easier to work with 890 kWh/month.

3) Total insolation area that gets 890 kWh/mo is 223 square meters.

4) Actual area to capture that 890 kWh/mo given a 15% conversion rate of solar cells is:

223: X as 15:100

22,3000 = 15 X

X = 1500 sq. m. (rounding generously up from 1486).

Now if you go for a much steeper price material that doubles the efficiency, you get half the area necessary (going from 15 X to 30 X) brings that down to 750 sq. m. which is something doable and you have probably seen those nice array of high efficiency cells on homes and such. Nanomaterials, however, weigh far less (even with mounting you are mounting something the weight of aluminum foil) so you could do up your home in Nanosolar. I really don't have a problem with that and if you have any yard space with, say, 15 degrees to 45 degrees clearance for viewing the sky, that would help a lot in putting up such a structure.

That is to power your home. And there are seasonal variations in the non-tropics, so you will want a bit more material for winter use as you will get less overall sunlight than the average say a 40m x 40m area (120 ft x 120 ft). The great part of Nanosolar is, in theory, it replaces your siding, gets built into roofing materials, and generally becomes thin, paste-up films you can use to put over just about everything that gets sunlight. And cheap enough to replace when damaged (in theory once they get a few more production facilities going and such).

But Prof. Nocera wants you to power your car by this system, too... an all electric or plug-in hybrid vehicle, no doubt. Time to run the numbers on cars, to see just what it is you are doing with those poor things. Lets take your nice 40 mpg non-hybrid vehicle... diesel or gasoline, both have the same energy density, so fuel doesn't matter. Average driving per car is... well, the numbers vary all over the place, but they center between 12,500 miles/year to 15,000 miles/year, with spare drivers like myself, when actively driving, having cut below that minimum, but not by much. I will use the former as the economy is changing to an online one and using economical delivery services to bring goods to your door instead of you going out and getting them.

Your average car delivers 20% of the energy from the engine to actual motion based energy for the vehicle, and the best that steel engines can do is 37% based on melting points of steel and so forth. There are many other ways to make engines, and some are trying to get into that lovely 50%+ territory, but they are also far more sophisticated than your basic 4-stroke engine. So it is time to start running the numbers:

1) Average distance driven is 12,500 miles divided by 40 miles/gallon - 312.5 gallons of gasoline. Hmmm... call it 315 gal. for utility's sake. Round numbers are easier to work with and as the works of mankind are less than efficient at most things, I round up to capture inefficiency. And obey the laws of thermodynamics.

2) Delivered energy, and lets assume with good aerodynamics, low rolling resistance tires, and a better than average efficiency engine that your car gets 25% efficiency in converting gasoline to motive power. That is the energy equivalent *delivered* of, again rounding up from 78.75 gallons, 80 gallons of gas or diesel.

3) Per gallon of gasoline US is 36.6 kWh (from onlinecoversion).

4) Total delivered energy to your car, per month is amount used ( 2 ) multiplied by its conversion factor (3) or 2,928 kWh/mo.

Or over 3 times what your home uses.

Time to buy up some spare property as you have a car to run!

What, more than one car?

Say, just where *is* this 'extra energy' that Prof. Nocera is talking about coming from, anyways? Even with super-efficiency, low drag, low slung, low friction vehicles, and say you cut that amount in *half* you still need more property to run your car. Your car's energy budget is actually much higher than that of your HOME.

Ok, now that you have expanded your property (neighbors? you don't need no steenkin' neighbors! you are being GREEN) and are going to see about what you have to do about the good Prof. Nocera's system. It is, as stated previously, a fuel cell which is technology that has been around for... well, conceptually the 19th century if memory serves but reliably since the 1950's and NASA's need for a compact energy source it can charge up and then have discharge as needed. As a form of battery, what fuel cells do is add energy in (electricity, by and large) and split up water into hydrogen and oxygen. They are extremely efficient at putting the two back together and getting three by-products on the catalyst material: electricity, heat, water. The 'round trip efficiency', that is the efficiency of electrical energy to crack water and then to put it back together again and get electricity is between 30% and 50%. Using a fuel cell that operates efficiently at a high temperature does get higher efficiency (up to 90%) but those operate around 1500 degrees F (800 C), which puts it into the furnace category of heat containment.

What Prof. Nocera has done is work on the front end cracking/catalyst portion, to get a better system for actually getting water to split without really noxious chemistry involved. What has to be factored in is the energy lost in splitting the water will not be returned due to heat loss and other inefficiencies in actually performing that task. Electrolysis of water can be, theoretically, very efficient, up to 50 to 80% efficient getting the molecule to split apart although more realistic numbers come in at the 30-45% range. Oh, and your efficiency goes down using air to do the work, so pure oxygen is prefered because that is another 10% or so loss, so you do want to keep the pure stuff around... All of that is part of the loss in the 'round trip efficiency': getting water to split up via electrolysis, pressurizing, utilizing oxygen vs air. Plants, as in the green, leafy kind, actually don't produce electricity, but form longer chain hydrocarbons that come in the form of carbohydrates as they much prefer to actually have a chemical diet than electrical one.

They do have a catalyst, called chlorophyll, but it is doing something a bit more difficult, which is why Prof. Nocera was so certain of the outcome. Actually, if you grew photosensitive bacteria in sunlight you can duplicate that... like algae. Although it is possible to eat some kinds of algae, we generally prefer electricity as an energy source for our homes and vehicles. That higher amount via the ceramic high temp system uses those temps on both cracking and rejoining to facilitate both, but is still not in wide use and has support problems due to the need for its operating temps and output constancy. Thus that round-trip efficiency is one of 30-50%, give or take a bit on the high end. So now we can start to see how fuel cells, operating at highest rated efficiency (not theoretical) start to look as storage systems.

1) Daily energy your vehicle needs on average - 2,928 kWh/month or, divide by thirty and round a bit, 100 kWh/day.

2) Using 45% efficiency of the entire fuel cell for round trip, means that you will need 222 kWh/day and I will round down, at this point, to 220 kWh/day or 120 kWh MORE per day just to run the fuel cell. Lead acid batteries get you 90% efficiency, just so you know.

3) Total energy via fuel cell per month: car - night charging - 6,600 kWh; the rest of your home - 890 kWh. That is, yes, 7,490 kWh.

Want an efficient lifestyle?

Plug in your car and sleep during the day, and then use the inefficient energy at night and get on 'the graveyard shift'.

Then you will be living a GREEN lifestyle by avoiding the sunlight.

No wonder Bruce Wayne gets such high marks: he is leading an energy efficient life.

[end section]

Now lets try that from the top!

The parts that can be salvaged are from the home daily use section and effeciency amounts, but my incorrect reading of my own, damned post means I need to re-do the math.

Insolation - 4 kWh/sq.m./day!

Avg. Household Use section still the same - 890 kWh/month

So, average insolation - 30 x 4 = 120 kWh/sq.m./month

Effective useful insolation using 15% efficiency per sq.m. - 18 kWh/sq.m./month from solar cells.

Thus, 18 divided into 890 gets you 49 sq.m. collection area for the average home. Yes, that number did seem wacky above and should have been an in-process tip-off... grrr...

Call it 110 sq.m. for your average home, average days, average insolation (you do get more insolation in the summer than winter, when you need it).

Your car's motive needs (absent waste, and yes I expect this is lower once you change drive train to batteries and such, but for current state of the art vehicles) - approx 3,000 kWh/mo.

Amount of solar cell space you need for your car - 18 divided into 3,000 - 167 sq.m.

Space needed for your home and car, on average - 216 sq. m. on average.

Or about 15 m per side of collection area if the energy was going directly into your vehicle, which it isn't.

That 3,000 kWh/mo has to factor in the 45% round trip efficiency of the fuel cell system - which gets you to the 6,600 kWh/mo using the fuel cell as storage. Or 366 sq. m. of colletion area, which is just a bit over 19 m per side, just for sizing.

Somehow lead acid batteries begin to look really good here... and you still wind up with the Batman lifestyle if you want a lower collection area.

The variables are: efficiency of the solar cells (and I am giving them a lot here), efficiency of the fuel cell (in theory it can get up to 80%, which is still not the 90% of lead acid batteries), and just how 'average' you live. Unless you have a different need for the hydrogen and oxygen, my bet is that you won't want a fuel cell unless it is damned cheap compared to a lead acid battery system. And a good way is found to store the gases.
