I was a college professor at the Saigon Institute of Technology in Ho Chi Minh City, Vietnam. Here are some of my earlier results with Algae. My algae died, my nutrients killed them, too much light, not enough light, you name it, it happened to me. First of all, it isn't that hard to make biodiesel from waste oil. In fact, it's pretty easy.
Soon, my students were helping me, then they started talking to their parents, who were business owners, and they came to me wanting me to do the same for them, etc. More experimentation. My websites: algal fuel
