• One floating element - everything
inside
• Motion energy is directly captured
by generator
• Direct conversion, no hydraulics, no
joints, no gears
• Proven industry components
• Simple and patented
Our Innovation – the Penguin WEC
How it works DIRECTLY FROM MOTION TO ELECTRICITY
The device fully encapsulates a rotating eccentric mass that is actuated by
waves, driving a generator typically used in wind turbines
