Phase change material thermal power generator

This invention describes a power generator designed for a submersible vehicle. It uses a material that changes its size in response to varying water temperatures encountered at different ocean depths. This size change pushes a hydraulic fluid through a motor, which generates electricity to charge the vehicle's battery, and the fluid is then reused.

Why it matters: Advances in phase change materials and battery technology since 2008 could significantly improve system efficiency and viability for ocean thermal energy conversion.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModeratePhase change material, hydraulic system, motor, pressure vessels.
