Robotic kelp farms promise a competitive, abundant source of carbon neutral fuel

Kelp can be harvested in the ocean and turned into carbon-neutral biofuel. Because kelp can grow more than a foot a day and is easy to process, the production can be cost-competitive with fossil fuels. A startup is using elevators to grow kelp farther out in ocean waters. The technology is Read More...
