There are many types of biofuel currently being researched. One type, algal biofuel, is often considered great in theory, but questionable in practice. That perception has started to change in the last year, and may soon be gone.
Cnet recently reported that Joule, a start up company based in Massachusetts, received a patent for a type of algae that secrets biofuel. What’s more, the algae only need sunlight, CO2 and a bioreactor to produce diesel fuel. Typically, biofuel from algae is produced after several steps. Joule’s process is the first to produce diesel fuel directly from algae. The picture below, from Cnet, is a diagram of how the Joule system would work.
