28-ton, 1.2-megawatt tidal kite is now exporting power to the grid
The linked article is about Minesto's Dragon 12, an underwater device that uses tidal flows to fly around like a kite and harvest renewable energy. Unlike other offshore power options, it is simple to install and produces more energy than other designs. It has been deployed in Denmark's Faroe Islands and connected to the grid to begin delivering energy. The cost projected by Minesto is around $108/MWh with costs falling.
