biofuel stories

If you plan on steaming a huge Navy ship around the globe, it's going to need a lot of fuel to keep it running. That's a problem when you're thousands of miles from home in hostile waters. But what if you could simply make your own fuel using the seawater that surrounds you? That's what the U.S. Navy wants to do, using a two-step process that turns seawater into jet fuel.
Treehuggers have been powering their old Mercedes-Benz Diesel cars with used cooking oil for years, but now it's starting to creep deeper into the fuel we use to power our airliners. Last year we saw how Alaska Airlines ran some tests using a 20 percent biofuel blend, but now Air Canada has upped the ante by going with a 50/50 blend of jet fuel and old used cooking oil.
According to mad scientist Harshad "Mr. Fusion" Velankar*, we throw out a whopping 323 million tons of cellulosic materials that could be turned into usable car fuel. Well, after digging through some animal dung, he and his fellows think we could turn that junk into gas, without having to modify today's vehicles.
