Here’s one more attempt at ocean wave energy. Note that this one is not just bad, it’s pitiful. As waves pass a floating barge, water enters an L-shaped chamber (shown left) as the wave rises and exits when it falls. …

The University of Plymouth To Host European Wave and Tidal Energy Conference (EWTEC)
I’m happy, yet surprised to see this. Interest in hydrokinetics has fizzled over the last 5 – 6 years, largely as a result of the plummeting price of solar and wind. That said, in September 2021, interested parties will join …

Eco Wave Power To Install Ten “Floaters” for Ocean Wave Energy Project in Israel
Pictured here is a set of devices that are designed to extract the kinetic energy out of ocean waves. The rising and falling water lifts and drops the blue paddles which compress a fluid, whose tubes are connected to onshore …

Give Your Five-Year-Old the Gift of Science This Christmas…No, Wait, She Already Has It
Here’s a video on hydrokinetics that I hope readers will check out. We Americans live among the most scientifically illiterate people on the planet. But that’s not really the issue here. If you took 100 average five-year-olds to a slowly …

Ocean Current Doesn’t Represent a Threat To the Environment
A reader notes: While I am a huge supporter of ocean wave and tidal energy, I adamantly oppose messing with ocean currents. Water follows the path of least resistance, so it’s very easy to disrupt current patterns that have countless …

What’s Not To Like About Big Hydro? Plenty
While hydro energy is carbon-free (after the construction), there are numerous environmental drawbacks. Here’s an extremely minor one. The world’s largest dam, China’s $30 billion, 22.6 gigaWatt Three Gorges, when completely full, will retain 9.43 cubic miles of water, weighing …

Tidal Energy
In my quest to learn Spanish, I try to read articles on renewable energy in that language. Here we have: La empresa líder mundial en energía mareomotriz, Nova Innovation, ha completado con éxito su proyecto de fabricar su turbina mareomotriz de accionamiento …
Ocean Wave Energy Concept
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:
