Why Wave Power?
 
 


 
 


THE POWERGIN™ OPERATIONAL DESCRIPTION – how it works

A typical PowerGin™ has rotors that are 80 - 100 feet long and 10 feet in diameter. The size is somewhat dictated by the wave period and energy output specification. Wave energy is focused by the wave ramp and the rotors and is funneled into the “buckets” called energy capture units on the ramp side of the rotor. In the case of smaller wave states; the water moving up the wave ramp artificially becomes a larger wave and crests to help fill the buckets. The buckets are mounted in a dense spiral pattern around the perimeter similar to hydro electric turbine blades which provide a high surface area to catch wave energy. As the buckets on the ramp side of the rotor fill with wave water, the rotors begin to turn. Water is emptied out of the bucket instantaneously when it is submerged under the water by a patented gravity driven flap on the bottom. The flap slams shut in one direction and opens in the other. The two rotors rotate in opposite directions which maintain balance and continuous rotary power flow.

The cones located on each end of the rotors house the power take off equipment. During rough seas the PowerGin™ will continue to make electricity until the waves become too rough and the wave ramp will draft the device under water to protect it from damage.

 

The PowerGin™ technology solves the most problematic issues faced by wave energy converters today.

  1. Wave Power Conversion – The best in class wave energy converter converts electricity at 18% but most are around 12% depending largely on the rise and fall or vertical component of the wave. The PowerGin™ makes use of both the horizontal and vertical energy components to achieve higher conversion rates of at least 20-30%.

  2. No Power Output in Low Wave Resource or Variable Wave States – Most of the US eastern seaboard and Southern California wave energy resource has been found to be too low to operate existing wave energy conversion technology. The PowerGin™ uses a proven technique to focus and concentrate the wave energy and also convert it directly into continuous rotary motion. Our technology makes it easier to capture the energy and also allows us to efficiently make use of inconsistent and much lower wave states than over topping or oscillating devices. The target market for the PowerGin™ is Southern California and similar resource areas around the world where wave technology is not being considered.

  3. High MW output per Device – The solar energy contained in waves is ~25 times more energy dense than the original solar rays. It is also much more energy dense than wind power. We use this energy density to our advantage and can size one PowerGin™ to be as much as 20 MW of output. This is equivalent to 8-10 wind turbines combined.

  4. Reducing the Cost for Undersea Cable - Multiple PowerGins™ connected together will form an ocean-based Wave Power Park™ and further reduce the overall cost by spreading undersea cable cost.
