It sounds like a child’s question: can you generate solar power underwater? The answer, according to Phillip Jenkins and his team at the US Naval Research Laboratory, is yes. The researchers recently demonstrated a method
for harvesting solar power underwater at depths of 30 feet.
Currently, the only option for underwater energy is batteries, which shortens the amount of time an underwater system can be powered. Having a source of renewable energy underwater opens up the possibility for long-term installations of autonomous systems, including systems for communication, environmental monitoring and networks of sensors.
