what you would be more advised to take aim at is the politics of the limited pie.

And what about this??? It's in italian, but it's easy to understand (or you can always translate it...) http://it.wikipedia.org/wiki/Solare_termodinamico
Just imagine how many areas there are in the world like deserts where you could build such plants....we could solve energy needs for all the planet...if only we were less individualist......

Puppy is TOTALLY green!

Not only does it effectively double to triple the lifespan of a useable computer, but it gives people reliable free access to the only (comparatively) unrestricted and unbiased information source there is...the internet. If we are as a species to avoid environmental collapse, we need to be educated and informed. We also need to update and reform the our financial system, and the activities that are made "profitable" by it. With the general amount of debt in most countries vastly surpassing the amount of money there is to pay it back, new technologies find it hard to gain a foothold while there is so much money invested in old technology...i.e. OIL

The "light bulb effect" (make them last half as long, sell twice as many) doesnt just apply to commercial software and computers, it applies to all technology we use, cars, washing machines etc. Linux/Open source is currently the only example I know of of unrestricted, licience free and non commercially driven technology around. Economic literacy from free media like the internet, together with the open source development methodology (which could equally be applied to cars and other technology should patents not exist to prevent it), will eventually produce a change in our mindset.

All of humankinds problems have always been resolved using technology, and puppy/linux is one of the first examples of the type of technology that will progress us as a species.

I recommend anyone reading that cares about these things to watch the most popular "free" film in the world, that is only able to be delivered because of free software and internet technology. This film is called "Zeitgeist" and can be viewed from here

i always assumed money was printed by governments, i didnt realize that it was a gift from the gods.

I expect you are referring specifically to Representative money or Symbolic money, in which case, you are absolutely correct.

Certain resources, which can also be used as money, certainly seem to be "given from the gods." Many of these resources are limited. Re-using resources reduces the stress of limited availability. Thus, Puppy is green -- at least in certain ways. (One often has to use qualifiers and weasel words since so many answers seem to be predicated on assumptions within the question.)

Solar seemed great until I found out that they lose 1/2 their output in 10 to 20 years.
So they need to be replaced after that time ( expensive & nongreen! ).
The new solar cells may last longer, I don't know.
They're simple to use & maintain but don't pan out so well for large powerful setups.

Wind generators last 10 to 20 years with little to no maintenance.
Expensive to setup & maintain but they're rebuildable & so ecofriendly.
They work very well for larger high power setups ( house & up ).

The monitor, maybe, some serious kernel hacking would be needed for anything else from that era! (IMO)

That's why I specified the monitor. I'm not sure you could get Linux to run on an AT.

The AT units used the Intel 80286 CPU. There were various attempts to get Unix running on them, and none worked well because of architectural issues with the CPU. (Like, it only allowed one real mode session at a time, and there was an instruction to enter protected mode and get a larger virtual address space, but none to leave it. You had to do a CPU reset. ) Also, Intel CPUs use a segmented architecture, instead of a flat linear address space.

On the original PC using the 8088 chip, you had a total of 1MB of addressable memory, and a segment was 64KB. MS-DOS had six different memory models a programmer had to be aware of, depending on whether their code and data fit in a segment or slopped over to multiple segments. A 286 had virtual memory, but IIRC, a segment was 16MB, which is nothing by today's standards. The 386 was a proper 32 bit processor with better memory management capabilities, more than one rael mode session at a time was possible, and a segment on a 386 was 4GB.

Unix became a lot more possible on Intel CPUs when the 386 was available.

OTOH, I still own an AT&T 3B1 computer, which was a desktop machine intended to compete with the IBM PC. It used a 10 mhz Motorola 68010 CPU, with a bit mapped monochrome console screen and GUI, and would boot and run a version of AT&T Unix System V Release 2 and run apps and perform useful work in one megabyte of memory. Give it more and it flew. I had a client back then using a 3B1 with four attached ANSI terminals and a printer, running a custom distribution management application. The box had 2MB of RAM. Performance was acceptable.

I looked at my 3B1, then I looked at my AT clone which just about ran Windows 3.11 in 8MB of RAM, gazed in teh general direction of Redmond, WA, and said "Microsoft, what are you doing?" I stilll say that.

Hmmm.

Solar cells lose half their output in 10-20 years and need to be replaced.

Wind generators last 10-20 years.

So in 10 or 20 years, you are looking at costs, either way.

Wind power and photovoltaic share two qualifications: they are capital intensive and they are site dependent. That is, they cost a lot to build/install, and can't be used everyplace. Wind turbines are big and require large open spaces to put wind farms. Photovoltaics require a lot of surface area in places where you get a lot of sun.

Both are valuable, but neither is usable everywhere, and neither by itself is a panacea.

it is groundbreaking discoveries like this that will get us to that paradise planet in the distant galaxy.

there is enough geothermal energy in this planet to last so far into the future that earthlings will have long left for "greener" pastures in another galaxy before it is exhausted, even if it is used in the most inefficient manner available.
Never, ever underestimate the human race's ability to waste.

Just look at computers. Every time the processing speed increases, software adds enough bloat to compensate.

Increase the energy available, and we will find a use for it. Things that were once expensive and rare due to excessive power needs would become cheep and widespread.

If you build it, they will come.


EDIT: Though, I'm not sure whether we could find a fast enough means of extracting the energy to cause any issues. In that sense, yes it could last for a long long time.
