Algae Bioreactors can be used to create a variety of fuels and feed while taking CO2 out of the atmosphere. Per acre, algae bioreactors have much more capacity to create biofuels than other approaches to creating biofuel. Algae-based fuels also don't drive up the price of household food as much as using Corn, Soybeans, and Canola to create biofuel.
GreenFuel
is a leader in algae bioreactor design with headquarters in Cambridge, Massachussetts . GreenFuel describes itself in this way:
GreenFuel uses a portfolio of technologies to profitably recycle CO2 from smokestack, fermentation, and geothermal gases via naturally occurring species of algae. Algae can be converted to transportation fuels and feed ingredients or recycled back to a combustion source as biomass for power generation. Industrial facilities need no internal modifications to host a GreenFuel algae farm. In addition, the system does not require fertile land or potable water.
The use of Algae Bioreactors to create hydrogen fuel seems to me a very promising green direction to move in and developments in this area would be worth investing in.
It is noteworthy that Robert Metcalfe, co-inventor of Ethernet and founder of 3Com, is the interim CEO of the company.

In defense of biofuels |

Reading a 3 volume series called "Alternative Energy". In Volume 1, the use of biofuels is defended (p. 63):
Bioenergy is less polluting than fossil fuel-produced energy in respect to carbon dioxide. Biofuels contain carbon that only recently was in the Earth's atmosphere, so the carbon dioxide released through burning them does not add to the total carbon dioxide in the air. Fossil fuels, however, contain carbon that was removed from the atmosphere millions of years ago, and they emit large amounts of extra carbon dioxide when they burn. Replacing some fossil fuels with biofuels may help ease global warming, lessen air polution, and clear the world's air.
