Do biofuels compete with food for land resources? The debate rages on. University of Arizona biologist Robert Glenn, though, has a great compromise – grow the biofuels under the sea, where they won’t get in the way of food production.
Glenn focuses on Salicornia bigelovii – a plant known as a halophyte (one that loves saltwater). According to Global Seawater, a company that studies possibilities of renewable, ocean-based agriculture, an acre of Salicornia would yield 90-100 gallons of biodiesel. They are experimenting with the technology in Mexico, and other projects are underway worldwide.
Proponents such as Glenn claim that there are hundreds of thousands of underwater square miles that could be used for this sort of application. I’m sure that the ocean has viable real estate for a project like this, the question is – where? Are there suitable lands near shore, or will companies have to sail out to the middle of the Pacific? And how does one go about harvesting an underwater crop, anyway? It sounds expensive.
It’s a good idea, though. There’s a lot of potential for energy in our oceans… time to tap it.
