GM Cars Using Bio Fuel
Renewable, bio fuel is not a new idea. It has been in development for long. What is new - is seeing it in mass production. GM has announced the new line of E85-based cars.
Important thing is that, it seems, this type of fuel has some muscle. Pay attention that GM cars are large SUVs, not like the tiny electric hybrid crap Toyota produces :)
It really looks like a breakthrough. Very excited.
