It’s Jammin Band Friday. Not only that but I have spent so much time this week hyping the Wind Power 2009 conference/convention that I thought I should end on a surfin note:
It is a little know fact that the moon is moving away from the Earth at about an inch per year. We know this because on one of the Apollo Landings (quick for those of you who don’t believe that they ever happened -CLOSE Your Eyes) they placed an aluminum block on it’s surface. Since that time and with intensifying accuracy we have been bouncing lasers off of it and this has allowed us to determine the distance to the moon (its original purpose) but the unexpected find that that distance is widening…Anyway this means that eventually the Moon will drift away into space. I think we should harvest its today power while we can. I mean in a million years or so it could be gone. Here is a huge thought problem for you…Where will it go?..Whoa

Wave power generator cranks up off Portuguese coast, and Oregon may be next
The world’s first commercial wave power project has cranked up at last three miles off the Portuguese coast, CNN reports. The first phase is expected to generate 2.25 megawatts, enough power for 1,000 homes, according to the Guardian.
“If successful, a second phase will see energy generation rise to 21 megawatts from a further 25 machines providing electricity for 15,000 Portuguese homes,” CNN says.
The generators, made by a company called Pelamis, are three red cylindrical converters (shown here) which are partially submerged in the Atlantic Ocean. “Moving up and down on the endless waves of the open sea, they convert motion into electricity, without emitting any of the carbon dioxide that is warming the planet,” the Guardian notes.
Novel Wave-Powered Generators Deployed in Sea Trials off Florida Coast
Technology from SRI International Offers Clean Energy Production from Ocean Waves
ST. PETERSBURG, FLA. – August 3, 2007 – SRI International, an independent, nonprofit research and development organization, announced today the deployment of a prototype buoy-mounted, ocean wave-powered generator off the coast of Florida in the Tampa Bay. Beginning today, SRI will test the wave-powered generator for approximately two weeks. The deployment is part of a program sponsored by HYPER DRIVE Corporation, Ltd., a Japanese company focused on development and deployment of wave-powered generators around the world.
SRI’s wave-powered generators can be deployed on existing ocean buoys that use batteries as their energy source. SRI’s new generator utilizes patented electroactive polymer artificial muscle (EPAM™) technology, and offers a renewable method to continually power ocean buoys. SRI will use instrumentation that allows remote monitoring of the generator’s output energy as well as wave height and buoy motion. Assisting the Menlo Park, California-based research team are researchers in SRI’s new Marine Technology Program, which is located in St. Petersburg, Florida. SRI is also working with Artificial Muscle, Inc., an SRI spin-off company and the exclusive licensee of EPAM, in the development of the EPAM components for the wave-powered generators.
“HYPER DRIVE is excited to work with SRI on this important application of EPAM technology,” said Shuji Yonemura, CEO, HYPER DRIVE. “We see great potential in applying this technology to wave-power generation around the world in the near future.”
“When SRI International opened its operations in St. Petersburg earlier this year, we anticipated great strides in marine research like we see today,” said St. Petersburg Mayor Rick Baker. “This energy-generating technology is a perfect fit for an industry based in St. Petersburg, which was designated Florida’s first and only green city by the Florida Green Building Coalition.”
Proving once again that there is little new under the sun (or the waves) is this 1932 version of the wave power generators that we showed here and here. It works on the basis of an “inertia motor” where “When a wave starts to lift the hollow sphere, the massive weight inside, because of its inertia, resists the movement and exerts terrific pressure in the lower cylinder. Finally the inertia of the weight is overcome. Then it possesses momentum. When the sphere reaches the crest of a wave, the combined effort of the momentum and the recoil of the huge, semi-elliptic springs exerts an equal pressure in the upper cylinder. The tremendous pressure is applied to oil, which, in turn, operates a special turbine which runs a generator. The current is conducted to the shore by submarine cable.” ::Modern Mechanix
