Researchers Find That Alligator Fat Could Be a New Source of Biodiesel. Alligator farming is alive and well in the United States and elsewhere but traditionally it's all about the animals' skin and meat.

War is Boring's Steve Weintz has a two-part article up on mobile nuclear reactors, called Atoms In Motion: Portable Reactors (part two here). The links referenced cover planes, trains, and automobiles (though calling the last one an "automobile" might be stretching the definition a little.)

The Air Car. A car that runs on compressed air. While not a new idea, or unique, the MDI car can reach a speed of 68 mph and has a claimed range of roughly 124 miles. To recharge the tank, the car reportedly needs to be plugged into the grid for 3 to 4 hours or attached to an air pump in a gas station for only 2 minutes. Is the wind of the future about to break? Will this technology pass gas as our urban fuel of choice?
