Submission + - Material breaks record for turning heat into electricity (nature.com)
ananyo writes: "A new material has broken the record for converting heat into electricity. The material had a conversion efficiency of about 15% — double that of one of the most well-known thermoelectrics: lead telluride.
For decades, physicists have toyed with ways to convert heat into electricity directly. Materials known as thermoelectrics use temperature differences to drive electrons from one end to another. The displaced electrons create a voltage that can in turn be used to power other things, much like a battery. Such materials have found niche applications: the Curiosity rover trundling about on the surface of Mars, for example, uses thermoelectrics to turn heat from its plutonium power source into electricity. That doesn't mean that the material is ready to be used on the next Mars rover, however: NASA has been looking at similar materials for future space missions, but the agency is not yet convinced that they are ready for primetime."

So no, when we run out of sand, we'll still have lots more carbon available.
you asume that we burn through both ressources at equal speed. (ok, we don't reduce either but if we count 'we use it' i am pretty sure we would need more carbon-based material then we use silicon-based material)

What about when we run out of sand!
by this time, we will have run out of carbon too..
There are at least 7 billion sources of carbon at the moment, and that's just the bipedal ones.
Oh what a genius you are! You just solved the Problem!

Well.. Bitcoin-Mining could be done without GPU-Support (but you wouldn't want to do it, since everyone else does it faster/more energy-efficient) you wouldn't make profit by mining, but you could "use" it still like regular money.
Bitcoint too could be made to work for everyday use. If anyone would like to spend real money/effort on it. But why should anyone?

besides from trolling around (and i mean both of you for this one) there are good reasons for both approaches.
the big problem i see is what evolves from the approaches
on *nix we have these nice litle directory /etc and the config files per user in /home
shurely the software should be designed this way you cant break it by configuration but... the most software i use IS designed this way
and to the speed.. lets just say that users who need to run a desktop-environment which uses 3D would have worse things to complain about than some cycles lost because of the config
on the other hand we have windows and his huge registry, saying that you should do everything and the user doesnt have to worry about this mess is nice.. but doesnt help, we all know sometimes you just HAVE to.
this isnt good design this is horribly
and by the way there is a reason why microsoft createt something equal to the user-home in the last years with much place for config files...
i dont think eaven microsoft will still continue to call his registry perfect
