Take a huge oceanic catamaran, stick a hydroelectric turbine underneath it, and hitch it to a 6.5 million-square-foot parafoil flying nearly a mile in the air. That’s a Korean research team’s new proposal for generating gigawatts of clean energy.

As the parafoil pulls the boat, seawater would be forced through the turbine, which generates electricity. The 800 megawatts of electricity produced would separate seawater into hydrogen and oxygen by electrolysis, and the hydrogen would then be stored on-board the ships.
