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 knows as hydrokinetics, i.e., extracting the kinetic energy out of moving water. Nowadays, however, at least as far as I’m aware, no one other than hobbyists are working in this area.
Of course, there is no rule that says you can’t spend your own money in any way you wish. However, what you’re going to run into in ocean current or any of the other flavors of hydrokinetics, e.g., wave, tidal, or run-of-river, is the old adage, “If you don’t care how you pay per kilowatt of electricity, I’ll get you all renewable energy you could possibly imagine.”
I’m fairly certain that the story here about the Japanese is false. Either that or it’s 15 years old.
Looks like communism! is the new mantra of the GOP. It’s coming from the least intelligent of their leaders to the least intelligent of their followers.
Could work!
What Obama says at left is a reminder that life in on Earth is tough enough without the planet’s most nation being led by a criminal sociopath.
As previously mentioned, it’s good to see the rising popularity of astrophysicist Dr. Brian Cox.
In this video, he explains that life on Earth is about 4 billion years old, but for the first 3 billion, there was nothing more complicated than single celled organisms. He suggests that this may be the reason that civilizations are rare in the universe, i.e., that they’re only around for the blink of an eye in terms of geologic time.
To me, it also makes one wonder why it took God 3 billion years to create the first multicelled form of life.
