These people say: A groundbreaking study from Florida Atlantic University reveals that ocean currents can generate 2.5 times more power than wind farms, offering an untapped, constant energy source. Unlike wind and solar, which depend on unpredictable weather, ocean currents …
Does a Clean Energy Giant Rise Power Beneath the Waves? Read More »
Most of what these people claim about their wave energy generation machine may be correct. The part about “low cost,” however, is dead wrong, which is why the world has given up on this and all other forms of hydrokinetics, …
Until about 15 years ago, before the levelized cost of energy (LCOE) associated with solar and wind began to plummet, the world had high hopes for the renewable energy technologies collectively known as hydrokinetics, i.e., extracting the kinetic energy out …
Here’s a video showing how a water wheel can generate electricity from a fast-running river. Is this BS? It depends on how you define “BS.” It will generate electricity to be sure. Will it do so cost-effectively? Not in a …
If you happen to live next to a year-round fast-flowing river, there’s no reason you can’t do what this guy did: buy a water wheel, connect it to a generator, and power your house. Will this be cost-effective? I doubt …
When I entered the renewable energy beat 15 years ago, devices like the one shown here, that extract some of the kinetic energy out of ocean waves, were considered potentially feasible. Over the years, however, we’ve both a) seen the …
Here’s another variation on the theme of converting the kinetic energy in ocean waves into electricity. Is it any better than what’s available now? No. This device allows the waves to move a long series of conductors up and down …
We will be hearing about niche applications of renewable energy until hell freezes over, and I have no problem with that. Having said that, I do object to developers of these technologies who claim that energy that is extracted from …
A friend asked for my views on ocean wave energy, which I sent along (see link above). I wrote, “Some of them are more pessimistic than others. In essence, there are still several different basic concepts, but none has any …
Well, let’s start with an easier question: Is there a $4 billion wave energy market? The answer: No. Not now, not ever. Why? Because the levelized cost of energy from wave energy is outrageously high, and it will never become …
