New Hydrokinetic Devices: Burden of Proof Is on the Inventor

Here an extremely common occurrence here at 2GreenEnergy: the submission of an idea from an inventor with a patent but no working model of the device.  Like so many others of this type, I respond:

Exec Turnover in the Wave Energy Industry Raises Suspicions

Nowadays, everyone’s alert to “fake news”; no one wants to be duped by deliberate lies that wind up in our media.  But, of all the different types of stories we come across each day, perhaps the most dubious are those

Tidal Energy Has One Key Disadvantage

Here’s a good article for those looking for an introduction to tidal energy, though it sugar-coats the subject of costs. The author writes: “Once it’s installed in the ocean, it functions cost-competitively to other forms of renewable energy.”

Scotland Set Yet Another Record for Renewable Energy

Even if the water temperatures were enticing, which they’re not, you still wouldn’t want to swim in the channel north of Scotland that separates the Atlantic from the North Sea (pictured). The tides are fearsome, characteristic of all ocean shorelines

Wave Energy Extraction Device

Here’s a note from clean energy entrepreneur Tom Woodbridge, President of Aqua-Magnetics, a company that’s developing a linear generator that directly converts the motion of wind chop and ocean swells into electric power.

Articles on Tidal Energy

We’ve all had the experience of flipping through an in-flight magazine and finding ourselves utterly incapable of generating even the vaguest interest in any of the articles they contain. We can almost hear the editor ordering the staff journalists to

Like All Flavors of Renewable Energy, Geothermal Keeps Improving

There is no doubt that geothermal energy occupies an important place in the pantheon of renewable resources.  Perhaps the post child of success in this endeavor is Iceland, a place where fossil fuels are hard to come by, and one

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

When It Comes To Renewable Energy, Everything’s Good for Somebody

It seems sure that virtually every form of renewable energy will eventually wind up playing a role–somewhere.  Just like the U.S. has wind in the Great Plains, solar in the Southwest and biomass in the Deep South, each part of

Ocean Wave Hydrokinetics May Be Drying Up

Here’s an idea for converting ocean wave energy to electricity that a fellow in New York sent me this morning. This is near the bottom of the scale of the ideas I receive, as it: 1) Invokes a technology that
