There is a new force on the wave-energy front. It’s called the Oyster. If it is successful in its debut this autumn, it could change the face of wave energy forever. You see, this giant electricity producing machine is different from conventional wave-energy machines. And those differences could make it extremely marketable.
The Oyster is unlike other wave power devices in that it uses hydraulic technology to transfer wave power to the shore to be converted into electricity. The machine has an 18m wide oscillator, which Dr. Ronan Doherty, Chief Technical Officer of Aquamarine Power the Edinburgh based company which has developed the first ‘Oyster’, says is a key to the machine’s design. The oscillator is fitted with pistons, which work according to wave action. The pistons pump high-pressure water through sub-sea pipelines to shore, where traditional hydro-electric generators use the high-pressure water to create electricity.

The U.S. Energy Information Administration (EIA) reported good news for renewable energy enthusiasts this week. Energy from renewable resources has increased significantly over the last year. It is now higher than energy produced from nuclear power.

A professor and student team have designed a network of modular floating docks to harness clean energy for New York City.
The eco-docks would generate the energy by harnessing tidal power from the city’s rivers; they should also help to add much needed green space above the dirty waters.

We were pretty excited about Pelamis’ wave power plan in Portugal., but not every technology written about here pans out in the end. Pelamis’ €9 million Aguacadora wave power project–the world’s largest–has been taken offline due to numerous technological and financial setbacks.

Editors Note: This is a guest post by San Francisco Mayor Gavin Newsom. See his last post for us on EV charging stations on Gas 2.0.
Today, San Francisco took a meaningful step toward turning the promise of renewable ocean energy into reality. We submitted a preliminary permit application to the federal government to develop a wave power project off our coast that we believe can generate between 10 to 30 megawatts of energy, with potential of up to 100 megawatts. When this project is fully operational, upwards of 100 jobs could be created in San Francisco.
Ocean power is a true “game changer” in the area of renewable energy. When wave and tidal power technologies reach commercial scale, they are expected to be able to provide thousands of megawatts of power to our coastal communities, dramatically green our energy portfolios and create thousands of new American jobs. In San Francisco, we’ve been doing our part to spur these technologies by aggressively advancing tidal and wave power pilot projects. We are 100% committed to this challenge.
