If you don't know about TED talks you should. They are usually quite interesting and informative. I've been doing some research for my new Integrated Global Studies School and I ran across this one which seems to intersect with growing the algae for energy.
Juan Enriquez presents the lecture,"Why Can't We Grow New Energy?". He wrote one of my favorite recent books, As the Future Catches You, which I've been especially recommending to all young adults.
Juan Enriquez offers a glimpse of some ground-breaking research to explore the potential of bioenergy. Our current energy sources -- coal, oil, gas -- are ultimately derived from ancient plants -- they're "concentrated sunlight." He asks, Can we learn from that process and accelerate it? Can we get to the point where we grow our own energy as efficiently as we grow wheat?
