This device apparently uses the kinetic energy of the moving water in the stream to lift itself up against the force of gravity. Or maybe energy was used to pump it up. So far, so good. But then it releases …

Bringing Hydrokinetics to Scotland
I can’t swear that the meme here speaks the truth, but it’s certainly possible, and more to the point, it illustrates the fact that hydrokinetics has important (although narrow) applications in the constellation of renewable energy. There are places that …
Tidal Energy
From “Science Enthusiast” France has taken a major step in renewable energy by activating what is being hailed as the world’s first commercial-scale tidal lagoon power plant. Located along the Brittany coast south of Saint-Malo, the facility features a massive …
Renewable Energy Concepts Can’t Violate the Laws of Physics
In the early days of 2GreenEnergy, my people and I were vigorously engaged in finding solid ideas in cleantech that needed funding in order to move forward. I vividly remember a conversation with a guy in Maryland who was trying …

Hydrokinetics Gone Awry
When I came across the meme at left, I was instantly reminded of a guy who called me from Baltimore, MD about 15 years ago, anxious for me to hunt up investors in an invention he had created. I was …

Ocean Current Energy
There is nothing new about this idea, and there is most certainly no “new research.” The density of air is so far below that of water that anybody could have told you that ocean current energy would have made a …

Generating Electricity from Water in Pipes
On the surface, this idea has merit, and it’s been considered here in the U.S. for at least the last 20 years. It’s never gone anywhere, because of: The extreme cost of replacing existing pipe, and The fact that it’s …

Why Norway Is a World Leader in Renewables
It’s true that Norway is a world leader in renewable energy. To be fair, however, they have a few things going for them. One is the hydro resource itself, which is enormous, especially considering the nation’s small population. The other, and …

Run-of-River Hydro — Just When You Thought You’d Seen it All
For some reason, people post a great deal of pure bullshit on social media on the subject of renewable energy. Some of it requires some level of knowledge of the subject to figure it out, but not the one at …

Is Ocean Current Energy Commercially Viable? Let’s Apply Some Logic Here
Please take a moment and think about the graphic at left. If I showed you a six-year-old tuna whose heart had been beating continually since it was hatched, would you conclude that the energy in a live tuna heart is …
