Seriously, Gasoline/Oil is not the answer. Ethanol is not the answer. Water isn't the answer as it's already more expensive than oil.....
I'm not coming at this from the Sky is Falling aspect..... If there are any signs of global warming, I believe it is tied to the cycles of the sun more than fumes from cars, but I also believe we can do better. An oil based economy is not good for multiple reasons up to and including all the problems it has caused in the middle east.
So, what is the answer? How can we continue to progress with little to no effect on the economy, ecology and world politics?
1. Increase the efficiency of power transfer, to decrease power loss.
http://www.bsharp.org/physics/stuff/xmission.htmlAccording to this article, there's up to 30% loss over long distances though power lines. If we COULD improve that, that would be helpful in terms of not wasting energy, and it would also make solar panel farms & wind farms more practical for getting the power from large, unpopulated areas to where it's needed. It might also make nuclear power plants more acceptable, as we can locate them further away from populated areas and not have an issue with "Not in MY backyard!"
2. Increase the efficiency & density of power storage. Make batteries that store more of the energy that is transferred to it, and hold more if it in a smaller area.
Upon fact-checking, Wikipedia says the efficiency of Lithium rechargeables are around 99%. . .I didn't realize what an improvement it was over NiMH. Still, they're expensive, somewhat dangerous, and lose their storage capacity as they get older (only good for a couple years in heavy-use (kept near 100% charge at room temp) before the permanent loss in capacity becomes very noticeable. Previous rechargeables weren't as efficient: nickel cadmium and nickel metal-hydride batteries are only around 66% efficient. I've read articles here and there about improvements in the amount of energy stored in a given-sized battery, but can't recall them now. That's obviously something that would help power vehicles.
http://en.wikipedia.org/wiki/Lithium_ion_battery3. Alternative means of producing power. Fuel cells, increased efficiency of solar power, wind power. It seems like every day I'm reading about improvements to solar cells. Here's something I read today:
http://www.physorg.com/news96557368.htmlI don't see ethanol as a solution, as there's a lot of resources & effort involved in the growing of crops, harvesting, making & transporting the ethanol.
What do you mean, water is more expensive than oil? I wasn't aware of that. DRINKING water, maybe. Did you know that 20% of the world's fresh surface water is contained in the Great Lakes?
EDIT: on further thought, I recall that I can get a gallon of drinking water for well-under $1.00. It wasn't long ago that I could get it for fifty cents, but I haven't priced it in the past few years.
