A reader asked me to comment on this (larger version below). There is no doubt that it will generate some power in choppy seas. It’s one of dozens, perhaps hundreds, of different ways inventors have developed to extract some of …

Fake News in Renewable Energy
For some reason, there is an enormous amount of fake news in the renewable energy sector. Why? Who benefits?

Ocean Wave Power Generation
Here’s a short video on one of the many variations on the theme of converting the kinetic energy of ocean waves into electricity. A couple of points:
Interesting Twist on Hydrokinetics
Here’s a renewable energy concept that I’ve been seeing here and there over the past decade. It’s a means by which a city can generate clean electricity from the water flowing under streets through pipes.
Concept in Ocean Wave Energy
Here’s a video on a device on the Brazilian coast that extracts the kinetic energy from ocean waves and converts it to electricity.
Debunking Claims in Hydrokinetics
A reader asked me to comment on the validity of the Wave Roller, a device seen here for extracting the energy from ocean waves. It’s described by its proponents thus:

Wave Energy Concept
From this article on wave energy: A U.S. Navy test site off Oahu is now home to the world’s largest-capacity wave energy device, the Ocean Energy 35.
Electrifying the Developing World Requires the Right Toolset
About half of the people living in Africa do not have access to electricity, and that 50% figure rises rapidly when we look outside the urban areas. This results in poor health, limited education, large, unplanned families, and low personal …

Generating Electricity with Ocean Waves
When 2GreenEnergy first came along a little over a decade ago, it appeared that ocean wave energy devices like the one shown in this video here might have a place in the constellation of renewables.
Croatia and Hydroelectricity: A Long-Standing Friendship
Some of the most powerful rivers in Croatia are dammed up to form man-made lakes so as to generate hydroelectricity. Apparently, it’s been that way since the late 19th Century.
