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 …
Renewable Energy Concepts Can’t Violate the Laws of Physics Read More »
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 …
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 …
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 …
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 …
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 …
Run-of-River Hydro — Just When You Thought You’d Seen it All Read More »
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 …
Is Ocean Current Energy Commercially Viable? Let’s Apply Some Logic Here Read More »
When my son was a little boy, he loved to see speeding railroad trains and the huge earth-movers that operated in landfills. My daughter preferred acting in skits with her little friends. We see this stuff playing itself out wherever …
Yes, but it’s a very tiny number, and one that is extremely unlikely to go much higher. Ocean wave energy is a subset of hydrokinetics, and, just a few years ago, it seemed that some flavor of extracting energy from …
The claim: Japan has activated its first megawatt-scale underwater turbine, the AR1100, to harness the power of ocean currents for clean energy. Anchored to the seabed, this 1.1-megawatt machine is now generating electricity from the relentless force of the sea. …
