As the float gets into warmer temperatures, the materials expand and the reverse happens when the float reaches colder regions. This expansion and contraction is used to drive a hydraulic motor, which generates electricity to recharge batteries powering a pump. The pump can change the float\u2019s buoyancy, allowing it to move up and down the water column.<\/p>\n<p>In theory, the engine offers an unlimited supply of energy, which can only stop if the ocean runs out of energy, which is highly unlikely to happen. The SOLO-TREC has already made 430 dives from the surface to about 500 meters and each time it produces about 1.6Wh of electricity, which is enough to operate the instruments onboard.<\/p>\n<p>Via: <a href=\"http:\/\/www.popsci.com\/technology\/article\/2010-04\/submarine-runs-eternally-thermal-power-ocean-currents\">PopSci<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Eco Factor: Self-sustainable UUV uses the energy of the ocean for practically limitless energy supply.
