Founded in 2010, Sea6 Energy wants to mechanize ocean farming, just as tractors did for agriculture, with its "Sea Combine," an automated catamaran that simultaneously harvests and replants seaweed in the ocean.
The machine travels back and forth between lines of seaweed, harvesting the fully-grown plants and replacing them with freshly-seeded lines.
