Apparently waves are pretty energy dense and could be used to generate power in a simple way…
“Alam estimated that one square meter of a seafloor carpet system could generate enough electricity to power two U.S. households.
He added that wave energy from just 10 meters of California coastline, or about 100 square meters of a seafloor carpet, could generate the same amount of power as an array of solar panels the size of a soccer field, which covers about 6,400 square meters.”
UC Berkeley engineers are developing a seafloor carpet system to capture ocean wave energy and convert it into usable electricity. The system could eventually help lower the cost of converting seawater into fresh water, easing the pressure during periods of drought.
For assistant professor Reza Alam, an expert in wave mechanics, the seafloor “carpet” he is proposing will convert ocean waves into usable energy.
“There is a vast amount of untapped energy in the oceans, and with increasing worldwide demand for power, the need to find cleaner alternatives to fossil fuels is critical,” said Alam. “We are also seeing greater population growth along coastal cities, so the ocean-based system we are developing would produce electricity in a carbon-neutral way right where it is needed.”
