Jared Bouck, a.k.a. Inventgeek, has a project on his site for building your own backyard photo bio-reactor, a sort of solar hot water system meets a fish tank, designed to grow a microalgae culture. The purpose of the device is to help remove CO2 from the environment. One such home device does very little, but if we all had one…
BTW: In case you’re wondering, the pump use to circulate the water gets its juice from the sun, not the local power utility.
