The team's lead scientist, Dr. Tim Devarenne, said:

"One of the issues with Botryococcus is that it grows very slowly. You just don't get a lot of biomass and on an economic scale that means it would not work to use this alga. It takes about a week for one Botryococcus cell to double into two cells, whereas a faster growing algae -- but one that doesn't make a lot of oil -- can double in about six hours. Maybe if we can transfer the genetic information to make these oils into quicker growing organisms like other algae that grow a lot quicker or a land plant that can produce large amounts of biomass, we can have them produce oil for us."

Of course, solar and wind energy are much cleaner sources of energy. But if scientists can find a way to activate the genes in other algae that can grow more quickly, then biofuel sources wouldn't have to take up land that could be used to plant food instead. Devaranne and his team still has to look more closely into the process, though -- they're still "a ways away from making a commercial product" at this point in time.
