"And sometimes you don't even need to press it..." In this video the little girl, at one point(5:55), touches a layer of oil above an algal culture saying that some algae don't need oil to be extracted.

My question is this: what species of algaes produce oil like this, where it forms such a layer above the culture? 

 Bob,

I call it BB. Botryococcus braunii

 Cool video. To embed a YouTube video into your post, follow the directions here.  Basically, do this <YouTube:EWIxDPl88ZU> where the <>s are [s. For example:

well its nice to see that evrything Ive been saying here since 2004 on this forum and working on for thirty years is finally happening across  our country... soon well have a 400 acre project underway as well as a few others  around the U.S. and in northern mexico. For anyone wanting to learn more in detail we are offering a series of seminars on "how to grow algae "more on that in  the events forum.. 

Thanks guys, this was all very helpful.
