Researchers Demonstrate Autonomous Underwater Vehicle With Novel Thermal Recharging Engine

Green Car Congress

NASA, US Navy and university researchers have successfully demonstrated the first robotic underwater vehicle to be powered entirely by ocean thermal energy. This expansion/contraction produces a high pressure oil that can be collected and periodically released to drive a hydraulic motor for electricity generation and battery recharging.

Siemens and Fjellstrand partner on battery-electric car ferry

Green Car Congress

The ship’s batteries will be recharged in the breaks between crossings, a procedure which only takes 10 minutes. Rather than a diesel engine, the ferry is equipped with electric motors to drive the ship’s two screws. These motors are powered by a Li-ion battery weighing 10 metric tons. Resources.
