Ocean Hydrokinetics: Wave, Tidal, and Current

Here’s a cool little video that I post largely because it serves as a microcosm of human ingenuity.  How many different ways can you invent to solve the same problem (in this case, extracting the kinetic energy out of moving

Wave Energy Continues To Make Progress, But….

I’m on the receiving end of a constant barrage of press releases that boast breakthroughs in every conceivable flavor of renewable energy. And, as much as I hate to be cynical, I have to believe that most of this stuff

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

Ocean Energy Is Important, But Faces Stormy Conditions

Here’s another post from the Energy Ocean show in Atlantic City, NJ.  As I mentioned earlier, ocean energy in its various forms, including off-shore wind, tidal, ocean current, wave, and OTEC, lacks the maturity of its cousins in renewable energy, e.g.,

Ocean Energy Show in Atlantic City, NJ, USA

Just a quick note to let readers know that this Energy Ocean show is really worth-while, and I’m very glad I built an extra day onto my trip to New York to attend it.  The introductory speaker opened the proceedings

Lockheed Martin Sails Into Wave Energy

Here’s what Lockheed Martin and its technology partner Ocean Power Technologies are doing in wave energy. I’ve seen similar concepts, and I’ve always been skeptical. Will this generate electricity? Of course. Will it do so cost-effectively? I’m not sure.

Infographic – All Forms of Energy on Earth Came from the Big Bang

As a part of our ongoing quest to produce “infographics” that lay out the basics of energy, I invite you to check out the chart here, presenting the notion that all the energy we harness and use here on Earth

Energy Videos for Newcomers

I’ve been preparing to make a few videos for newcomers to the subject of clean energy that answer basic questions on renewable energy, fossil fuels, nuclear energy, and the energy-related challenges we face.  I’ll be recording a series of short

Hydrokinetics: Clean Energy Business Plans Based on Hydro

Here’ s a short presentation on hydrokinetics, in particular, a few clean energy business plans that are based on run-of-river, ocean current, wave, tidal, ocean thermal, etc.  This is of particular interest to me as I go about recommending a

[The Vector] Harnessing the Ocean for Energy: the New Frontier?

The world’s oceans are a new frontier in the renewable energy world. Ocean energy is emerging and will be ‘make or break’ in the next five years, says the firm Pike Research that focuses on research and analysis of renewable
