Concept in Hydrokinetics
I awakened this morning to an interesting question in my inbox from frequent commenter and 2GreenEnergy supporter Brain McGowan, who asked: What’s your take on this hydrokinetic device? Coincidentally, a colleague of mine showed me an extremely similar device about six …
Concept in Ocean Current Energy
A gentleman from South Africa asked for my feedback on a new concept in hydrokinetics aimed at capturing energy from ocean currents. I hope a few readers will find my response interesting: Hi, and thanks very much for sharing this …
Hydrokinetics and Biofouling
Regarding a recent post on the validity of ocean wave energy, my friend, top-level author Tom Blakeslee (pictured here; see ClearLight Press) writes: Look at the underside of boats and docks…filled with barnacles and growth. Maintenance could be a nightmare. …
Identifying Solid Opportunities in Renewable Energy
An investor wrote me yesterday about his interest in pursuing a joint venture with a company in ocean wave energy. Like so many others hoping to experience the upside potential of renewable energy and looking to escape the “great recession” …

Harvesting Wave Energy in Peru
Those following the progress the world is making in wave energy may be interested in the website of these folks in Peru: Atmocean. I have to say that I love the name. It contains the word “ocean” and it’s pronounced …
The Endless Variety of Hydrokinetic Devices
For the reader who, for whatever reason, may be on a quest to check out every conceivable variation on the theme of extracting the kinetic energy out of moving water, here is Atlantis. Note that a great deal of discussion …
Can Ocean Wave Energy Be Cost-Effective?
The more I read about this, and the more time passes (perpetually bringing down the cost of solar and wind), the more I doubt it. Having said that, here’s an article on the use of wave energy in Africa. The …
The Law of the Jungle Applies to Wave Energy and All Other Forms of Renewable Energy
Here’s a good article on wave energy, i.e., the conversion of the mechanical energy from ocean waves into electricity. For what it’s worth, I’m hoping that this arena will one day succeed, and I agree that if it does, this …
