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 …

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 …
Ocean Current Doesn’t Represent a Threat To the Environment Read More »
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 …
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 …
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 …
For some reason, there is an enormous amount of fake news in the renewable energy sector. Why? Who benefits?
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:
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.
Here’s a video on a device on the Brazilian coast that extracts the kinetic energy from ocean waves and converts it to electricity.
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:
