The latest frontier for renewable energy is the ocean floor. A novel method of generating power uses a network of metal rods to tap into the currents that flow along the bottom of the ocean (and along riverbeds as well). Water swirls as it flows past the rods, making them vibrate. This phenomenon is painfully familiar to oil companies, which spend large sums of money minimizing such vibrations in order to stabilize offshore drilling equipment. “Everyone was obsessed with suppressing this motion,” says Michael Bernitsas (http://www.engin.umich.edu/dept/name/faculty_staff/bernitsas/Res_inter.htm), the University of Michigan engineer who developed the technology. “At some point it dawned on me that maybe we can do the opposite: Enhance it and harness the energy.”

When you think about it, if we could harness all these different sources of "free" energy: this one, using surface ocean currents, wind, solar, geothermal, various sources of biofuel like algae, seaweed, castor, jatropha, certain waste products like olive pits...do we really need oil except as a lubricant? There are even alternative sources for that.

Reading this I am reminded of the old Beach Boys song.....Good Vibrations.

Now try getting that song out of your head.

Good point, but algae can be used as a lubricant also. They are now working on using it in the manufacturing of plastics too.

Some start-ups in California have been given millions to find the correct way to produce it to make it cost effective.

I really believe oil is on it's way out.

And for all those "Make Marijuana legal" proponents.......Hemp Oil anyone?

Forgot to add, it is carbon neutral also.


I hope Obama addresses this issue every time he speaks, but so far it only seems to be the future airline fuel.
