The Ocean Waves are FREE! DIY (Do It Yourself) Wave Power!
Did you know that you can generate wave power from the Ocean Waves?
Did you also know that the world’s ocean waves hold as much as 10 TRILLION watts? That’s some SERIOUS wave power!
Watch this video, especially the part where the waves come in and start taking entire buildings with them! Clearly, we’re not talking about generating power from a Tsunami wave as the most important thing during a Tsunami is saving lives! When watching it, just imagine how useful this kind of power can be, even if destructive from time to time.
Here is an excerpt taken from a Popular Mechanics article:†
“According to some estimates, ocean waves around the world could hold up to 10 trillion watts of energy. If humans could harness that energy, we would be able to generate renewable, predictable and pollution-free electricity. But so far, few large-scale wave-energy projects have made it off the diving board—which means that ocean-wave technology is a free-for-all in terms of design. ‘There are many, many different types of devices,’ says Paul Jacobson, an ocean-energy leader at the Electric Power Research Institute. ‘The technology hasn’t developed to the point where a lot of the designs have been shaken out yet. And so it remains to be seen which devices will turn out to be the most cost-effective and efficient.’
These few ocean-power designs could help us to ride the wave into the future of energy”
But can ocean wave power be generated by Joe Consumer, you and I?
Honestly, not very easily. There isn’t a lot of information out there that would make it easy, yet, to DIY. And the real challenges to do-it-yourselfers lie in the enormous size of some of the equipment that is needed effectively generate wave power.
But for now, here are a few commercial wave power designs to pique your curiosity. Also, from Popular Mechanics.†
1. The Oyster, by Aquamarine Power
Much like its namesake mollusk, the Oyster sits on the seabed, opening and closing its jaws. The device is a large hinged flap attached to the ocean floor at a depth of about 35 feet. As the flap opens and closes, it drives hydraulic pistons that squirt high-pressure water onshore, where it drives a conventional hydroelectric turbine. “In essence, the Oyster is simply a large pump which provides the power source for a conventional onshore hydroelectric power plant,” says Carrie Clement, a spokeswoman for Aquamarine.† ¹
2. GreenWAVE, by Oceanlinx
When it’s working, the greenWAVE sounds like a big animal breathing, Tom Denniss, greenWAVE’s founder says. And as the vent breathes in and out, it turns a turbine hooked up to a generator. Each device measures 82 by 50 feet and has a 1-megawatt capacity. Oceanlinx has plans to develop a permanent version in Australia or Mexico, which it hopes to expand into a wave farm. GreenWAVE is relatively inexpensive as well, Denniss argues, because it’s made mostly of concrete, weathers ocean storms easily and has no moving parts underwater.† ²
3. Autonomous Wave Power Buoy, by Ocean Power Technologies
The PowerBuoy has two main parts: a moving float that’s 5 feet in diameter by 5 feet tall and a 25-foot-tall spar anchoring it. When the float bobs up and down on the wave, it tugs on the spar. That stretching gets translated into electricity by a rotary motor and generator.
One significant challenge to the design, says Phil Hart, OPT’s chief technology officer, was getting the buoy to properly resist the waves. In order to get electricity out of puny waves, the resistance between the float and the spar needs to be low—otherwise, the weakling wave won’t move the buoy at all. But bigger waves contain more energy, and by increasing the force needed to move the float, OPT can harness more of that energy. Thus, PowerBuoy needs low resistance at some times and high resistance at other times. To solve the problem, they’ve implemented a computer that adjusts the device’s resistance 10 times per second, leading to a big increase in efficiency.
Each PowerBuoy currently operating off the coast of Hawaii has a capacity of 0.04 megawatts, but an upcoming installation in Scotland may be able to generate up to 0.15 megawatts.† ³
So, as you can clearly see there are a lot of great ways already being implemented and designed to generate wave power. Again, there really aren’t too many ways to generate wave power for your own home, as the title of this article lead you to believe, but I believe you enjoyed this article nonetheless and found it interesting.

God bless you!
