Dam-Atoll's Energy Efficiency

Energy Efficiency:

The working scale model of Dam-Atoll was 25% efficient at converting wave energy to work (mechanical energy). We are confident that further refinements will get this percentage up to 50%. As a basis of comparison, the efficiency of a gasoline motor is somewhere between 15% to 35% in converting the energy of gasoline to work—an efficiency that carries a terrible price tag resulting from the output of global-warming gases and other harmful pollutants.

Wave Refraction

When the submerged atoll is dome-shaped, it refracts the wave path to its center

The exact shape of the atoll's dome is critical

the atoll acts as a kind of lense concentrating the wave energy

A Wave's Potential Energy Gets Changed To Kinetic Energy By An Atoll

A wave is nothing but energy

Waves And Potential And Kinetic Energy

A deep-water ocean wave is always half potential and half kinetic energy

Wave is all kinetic energy when it breaks on the center of the atoll
