Cool. I now envision a sewage plant with absolutely huge lagoons where the sewage is pumped after solids are removed and before further treatment. For example, a square inch of duckweed will cover an acre in less than two months. Seed 1,000 acres of lagoon with just a square yard of duckweed and in two months you’ll have 1,000 acres of biomass to skim off (they don’t even have roots). Or save a hundred square yards from the last harvest and have your next harvest in no time (they double every three days, you do the math). You’ll also have treated a whole lot of sewage in that time since they suck up nitrogen and phosphorus.
Effectively running your car on what you put down the toilet. I love it.
Come to think of it, a farmer could put a lily/duckweed lagoon at the bottom of his property to catch fertilizer runoff and actually make a profit off of what was formerly a nuisance and environmental hazard.

In all honesty I have a concern about biomass fuels such as methanol produced from crops in that what about soil depletion and what to do about that problem. Any farmers or chemists out there have an answer?
