At the ARPA-E Energy Innovation Summit, a company called Marine BioEnergy was showing a potential new way of producing an enormous amount of low-cost energy in a way that doesn’t compete for land area. Their idea is to use drone submarines to farm kelp out in the open ocean, and then process it into carbon-neutral liquid biofuel. Turns out there are a lot of reasons why this might be a very good idea.
