  1. The problem with fuels like biodiesel is the impact of the crops displacing food crops. Europe hig the buffers on this. However, Jimmy Carter (who gets a bad rap) actually set up the aquatic species (biofuels) project. They used ponds containing brackish water to grow diatomic algae. These can be up to 50% fat so very high energy and the other 50% is used for everything from food to animal feed. The ponds were built on desert land using salty water so had no impact on agriculture. The hard part was managing production at an even slightly reasonable cost.
