Summary : Some scientists have discovered algae is good alternative for fossil fuels. They want to grow freshwater algae in nutrient-rich waste water inside plastic membranes. They think that "the natural salinity of the ocean will draw the freshwater out, retaining the plants and nutrients. The membranes prevent saltwater from getting inside and killing the plants, while ocean waves keep the algae mixed and healthy. The process treats the sewage water, which is then released into the ocean." There are some problems with this concept though, like that waste water that had been treated so much would not produce good algae for the whole project. Another problem is that theirs not enough of algae that they've found to replace some oil companies.
