Amazing fuel sources

I thinks it’s really cool how the search for fuel sources that replace petroleum has evolved in the last decade. There are so many researches to find ways to sustain our ever growing need for energy. Some of these are almost unreal. For example it’s really hard to believe that algae can be good for anything yet research has shown that a lot of oil can be gotten from algae. An article in the IEEE spectrum talks about "Green gold". It talks about using algae as a biofuel in the coming years. An article in the London times talked about a bug that excreted oil.
