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.
Bosnia & Herzegovina Slowly Moving in the Direction of Hydroelectricity
My wife and I are with some friends in the Balkans just now, which, of course, positions me well to look for blog post material in this wondrous place, one I’d never visited.

Concept in Hydrokinetics
If you’re tiring of my posts on asinine/fraudulent renewable energy concepts, skip this one. Contrast this water wheel concept in hydrokinetics against the photo above and see if you can see any difference. I love inventors who use terms like kilowatts per …

Run-of-River Hydrokinetics
Does run-of-river hydro have the potential to make a contribution to our energy mix? Yes, in parts of the world that have incredible hydro resources that are hard to service with competitive technologies. By “incredible,” I mean strong, nearby rivers that …
