Looks like the algae scrubber is powered by artificial light. http://advbio.cascadeschools.org/06-07/biosub/about.htm The original BioCoil was designed by students at a highschool based on a similar design that a company elsewhere produces. They found their natural water sources polluted with with sewage, and looked at this company's work in water treatment. Later, the BioSub guy contacted them and asked last year if they would measure the CO2 consumption and O2 generation capacity of their design to see if he could use it. It seems to suit his needs. Here's a pretty good overview of what it is and was originally intended for, including a very detailed explanation of how it was designed and built: http://advbio.cascadeschools.org/97-98/biocoil.html The lead in page to the whole biocoil project over time: http://advbio.cascadeschools.org/Biocoil.html Very interesting! Now we can McGuyver our own air as well as water and food. -Adam On 6/28/07, Peter P. wrote: > Where almost indefinitely is defined as 12 days for now.
