Algae converted to crude oil in less than an hour, energy department saysPublication: NBC News Date: December 17, 2013 View Article
The day when planes, trucks and cars are commonly revved up on pond scum may be on the near horizon thanks to a technological advance that continuously turns a stream of concentrated algae into bio-crude oil. From green goo to crude takes less than an hour.
The goo contains about 10 percent to 20 percent algae by weight. The rest is water. This mixture is piped into a high-tech pressure cooker where temperatures hover around 660 degrees Fahrenheit and pressures of 3,000 pounds per square inch in order to keep the mixture in a liquid phase.
