Fuel Alternatives

I'm wondering what the most viable energy alternatives are. Ultimately what's needed is to find a chemical reaction that results in a high yield of energy and a truly harmless waste product. Better still, a useful waste product. Oxidizing (or whatever the right word is) hydrocarbons results in CO2 and H2O. I guess that's where the idea of Hydrogen power comes from: H + O2 and we get an exothermic reaction with a byproduct of ... H2O. And who can't use what amounts to distilled water? They could even put it in a collection tank and you could empty it into a reservoir at your house that is specifically used for waste water. Right now we use the same water source for drinking and flushing the toilet. Why not use our cars' waste for our personal waste? Or... we could make the collection container so that the owner removes it and places it on a water cooler. Obviously you would have at least two of these.

I guess this idea hasn't taken off yet because of the whole "I don't want to be immolated by my car"/Hindenburg thing... Plus, where are we going to get all of that pure O2 and H? And the cost of shipping it ...

Maybe the answer to global warming is reducing hydrocarbon consumption as much as possible while working on figuring out what to do with our bumper crop of CO2 that's just floating around. Surely someone wants a lot of CO2... Maybe there's an interstellar CO2 market that we need to tap into.

I don't know. I'm going back to work now. If there is one thing that we've learned in this monologue its that we need the help of CO2-deprived aliens. And that means we're that much closer to solving the world's energy crisis. You know, having figured out the alien component and all.
