‘Green’ Robot Hits The Waves, Runs On Ocean Heat
Â
A new underwater robot has been test-gliding continuously beneath the 4,000-meter-deep Virgin Islands Basin since December, powered by an unlimited supply of ocean heat.
The seagoing glider, which uses thermal energy from the ocean to propel itself, is the first “green” robot to explore underseas. It draws energy from the differences in temperature between warm surface waters and the colder, deeper layers.
In the photo above, the glider is resting on at the surface in the Caribbean before it once again dives into the Virgin Islands Basin between St. Thomas and St. Croix.
The idea for the thermal glider was first conceived in the 1980s by Doug Webb.
