most everyone in North America in this economy thinks he has to shop at walmart at one time or another.
Fixed that for you
People in Germany for example don't have to shop at Walmart, because Walmart doesn't exist anymore in this country. Fittingly because they failed to adapt to the new environment.
"2nd Thermo is a mathematical law"
It is a mathematical consequence of some models of the universe. Other models don't bring it as a consequence. Remember, we don't know how the universe behaves, we just have clues.
Sometimes I wonder if we are just like the people in Plato's Allegory of the Cave - staring at the wall, watching the shadows move and then try to come up with scientific explanations of the shadows' behaviour - without knowing what's really going on because there's so much that we can't see/measure yet.
The first German hybrid plant started operating in Berlin last month. Surplus wind power is used to produce hydrogen and oxygen. The hydrogen will be used to produce heat and energy, but will also be sold at local gas stations for use in fuel cells. So Vattenfall, Deutsche Bahn and Total seem to think that it's indeed worth it.
And there are projects starting next year that will built plants to convert the hydrogen into methane.
