Underwater Solar Power Possible?
A team from the U.S. Naval Research Laboratory has been studying the possibility of harvesting solar power underwater. It's true! Because now the only way to power up devices below the surface of water is with batteries, developing this science could benefit communication systems, environmental monitoring and other applications.
Currently this can only occur about 2 ½ feet down and they are working on changing this to a depth of 30 feet. Instead of silicon cells, the researchers are using gallium indium phosphide (GaInP) to maximize light absorption. Don't expect to see the results in the near future, just know that the military is continuing to use our tax dollars to create alternate power sources.
