I know this is a old thread, but it is interesting.
One thing to keep in mind is Japan, has industry. It was mainly industry, and a war that pulled us out of the last depression. Look at rome. these things can last a LONG time. Any war we fight now is only a drain as well. Since we do not produce most of the equipment now.
There are some factors we face Japan did not. Namely that our dollar is all over the place. It was not a wise thing to do long term. As we will likely learn the hard way. Others will decline with us. All the while we want to try to tie other countries to this bogus co2 limitation, halting growth. Likely with leaders insane enough to war over it, and a population who is divided, and cant even form their own thoughts in most cases. There are legitimate environmental concerns, many actually, but not co2.
This part is to Mike....
ethanol and bio diesel, can indeed be cost effective without subsidies even in our borders. The problem is corn lobbyists, lobbied for us to use corn, which literally takes roughly as much energy to make as we get out of it. Then we also have to pay for it at the pump, a second time. Completely ridiculous. However other crops can be well worth it, keep money in our country, and we do not even have to use prime farmland AT ALL. Sugar beets, are four times as productive as corn, and need way less input. but there are many other things that work as well.
Pretty much any open land in any part of the world, even the most barren deserts, can grow ethanol, even sustainably, with some crop or another. Most any organic matter works, to make some type of alcohol. Mesquite for instance, needs to only be planted and harvested, and produces as much ethanol per acre as corn, with really no input once established, is perennial(its a bush) and grows in places where there simply is not agriculture. We could easily retain bio diversity, and grow our fuels, keep the money in our country.
I think they are having issues with bio diesel last I heard. It works just fine, and is cheap to make, oxygen as a byproduct even, they use plankton I think it is, problem is it doesnt always stay stable for long periods.... But Im sure something could be done to remedy that, with some funding.
Thing is the profits would be spread far and wide, our current owners do not want that.... So dis info is rampant. But your right, our current policies on ethanol are simply insane.
