“Invest now!  This will make energy more affordable.” Never in a million years. There are small, isolated coastal villages where a total of a few thousand people may find wave-generated energy to be the best deal, though other forms of …

When I come across an idea like this, one that requires angel investment to bring this new concept in ocean wave energy into fruition, a project that is clearly asinine, I ask myself: Is this fraudulent?  Are these people simply …

I recently learned that a friend’s family owns a great deal of land on one of the Pacific islands owned by the U.S. that includes a huge reservoir of water high in the mountains.  I asked, “Don’t you folks pay …

Here’s one more attempt at ocean wave energy. Note that this one is not just bad, it’s pitiful. As waves pass a floating barge, water enters an L-shaped chamber (shown left) as the wave rises and exits when it falls.  …

I’m happy, yet surprised to see this.  Interest in hydrokinetics has fizzled over the last 5 – 6 years, largely as a result of the plummeting price of solar and wind.  That said, in September 2021, interested parties will join …

Here’s a video on hydrokinetics that I hope readers will check out. We Americans live among the most scientifically illiterate people on the planet.  But that’s not really the issue here.  If you took 100 average five-year-olds to a slowly …

A reader notes: While I am a huge supporter of ocean wave and tidal energy, I adamantly oppose messing with ocean currents. Water follows the path of least resistance, so it’s very easy to disrupt current patterns that have countless …

While hydro energy is carbon-free (after the construction), there are numerous environmental drawbacks. Here’s an extremely minor one.  The world’s largest dam, China’s $30 billion, 22.6 gigaWatt Three Gorges, when completely full, will retain 9.43 cubic miles of water, weighing …
