WOW, that's interesting!

That is very interesting.

1 acre of algae producing area will make about 20,000 gallons of oil per year.

Sounds like a great investment.

Maybe we can start removing the algae from the roofs and bottle it..

If you start collecting the algae from the roofs you clean, you will need a new slogan. Roof Cleaners: Reducing America's dependence on foreign oil, one roof at a time!

Of course there is one problem now, you guys gotta quit killing the algae.
