Imi the questions you raised does not make sense. First and formost how do you think the world produces salt, by just letting other country get it for them even thouh they have salt river. Second I know the process of making salt and how much time it takes, but you think salt that is produced for US population and China population are not formed the same way. They have population that is 10 time in US case and 40 to 45 times more in Chinas case compare to Nepal. About the Hydroponics and Aquaponics system I said it will take 3 to 5 months to understand to operate the system not produce food. Take for example all the tomatoes, lettuce, chilli, green pepper, cucumbers, etc... in US are produced by Aquoponics or Hydroponics system, how do you think they supply these items every day in the market, they created the cycle for production. For example, if California made tomatoes that can last for 3 months then another state would produce it for another three months that the California would supply that other states for. So when California is growing their tomatoes than that other state would provide it to them. These cycle help balance things out. You really think US is afraid of India? Now thats funny. Maybe China. Ok maybe China may not like the idea of US troops being in borders but in comprimise China may want to help us with protecting the border if it wants limited US influence. If you think back, there was a time when China wanted an embassy in terai but India objected, but had our leaders have said yes then it would have been different today. (http://www.eia.doe.gov/kids/energyfacts/sources/renewable/biomass.html) Read this! corn, sorghum, and wheat, as well as potato skins, rice, sugar cane, surgar beets, and yard clippings. As far as ethonal is concerned before you tell me to read it, read the fact about how you can crete ethonal and other fuels from many other things beside corns. Look up this fact before saying anything. Another thing you forgot is I mentioned other alternatives also. We have hydropower, then you have liquified oxygen and hydrogens that are abundent, then there is natural gas that one can manipulate for benefits. So there are many sources. As far as making an engine that works with this is concerned I know many people who understand the process and make electric motors that can do just that and have beening doing it. Most of them are enviornmental engineers. People already developed them in US they are not planning only. The govt is planning so it can find ways to make profit not because they can't.
