Re: Future of fuel?
I like the diesels running on waste fryer oil. They apparently smell like what the oil fried. If you were to market it right, you could have your choice of Fried Chicken, french fry, Apple Fritter, etc. scented fuels. Mix a few together for "Chicken BBQ" or "Thanksgiving Dinner".<br /><br />Using fuel to produce hydrogen by splitting water molecules would be silly and inefficient. Hydroelectric power can do it and provide the water to break down. Wind and Solar as well. Those systems could be as close to perpetual motion machines as we can make. No fuel to buy, just machinery to build and maintain to make fuel. Largely self-sufficient as long as there's water, wind, and sun.

<br /><br />I also like the idea of heating homes with methane collected from landfills and sewage fermenters, either human or animal. Everything from corporate projects to "Grandpa's Pig Farm Organic Methane". Fortunately that doesn't smell like what it came from.
