Running a plane on biofuel

Virgin Atlantic is planning on flying a 747 on an 80/20 mix of jet fuel and biofuel.

This is great, except when the biofuel comes from a crop that is fertilized with ammonia from coal, natural gas, or petroleum coke.

Someday, biofuel can actually be made from only the sun, and so actually be a truly clean energy source.
