Hydro-Electric Paddle Wheel Could Generate Electricity?

Posted on Friday, April 17, 2009 posted by posted by Mak @ 10:45 PM

John Bays says his invention could save him tens of thousands of dollars. Bays has built a "tidal Venturi hydro-electric paddle wheel". He tested the paddle wheel out on the Intracoastal Waterway and sure enough....it worked. Bays floated the paddle wheel down to this waterfront residence, where he says he'll eventually connect the paddle wheel operation to his house and generate energy.

Clean Energy from Slow-moving River Currents

Posted on Sunday, January 25, 2009 posted by posted by Mak @ 11:56 PM

VIVACE (Vortex-Induced Vibrations for Aquatic Clean Energy) invented by Mike Bernitsas, director of the Marine Renewable Energy Laboratory at the University of Michigan, is a device to harness energy in slow-moving water currents across the globe and turn it into electricity. Unlike water-driven mills, turbines or dams, VIVACE doesn't require fast-moving water _ most streams on the globe are slow-moving _ and doesn't harm the environment.

The envision is groups of cylinders in frames on the ocean bed or in streams, perpendicular to currents. As the water flow hits the cylinders, it creates vortices that cause the cylinders to move up and down. That energy drives generators to make electricity, which goes through cables to the electrical grid on land. The size, number and placement of the cylinders depends on the body of water.

A plan to restore Wellington hydro-plant for green electricity

Posted on Tuesday, December 30, 2008 posted by posted by Mak @ 8:27 PM

The National Trust wants the old Wellington Hydro-Electric Power Station restored and recommissioned to generate clean electricity. A plan to restore the defunct Wellington Hydro-Electric Power Station includes re-commissioning the 52-year-old plant to generate enough “green” electricity to power the nearby coal-mining town of Collie, the National Trust has revealed.Estimates showed it could generate about 9600 megawatts an hour of electricity from a minimum 200 days or more if water was released more often.

Hydro-Hydraulic Invention for Micro-hydro Power Generation

Posted on Friday, March 21, 2008 posted by posted by Ecacofonix @ 9:21 PM

Pakistan inventor Sarfraz Ahmad Khan has been working hard to develop new hydro technologies like this hydro power invention. His latest concept features the run of river active setup of micro hydro power generation blended with basic principals of hydraulics. This concept explores the possibility of transmitting the (collective) mechanical power gained from run-of-river hydro setup by converting it into hydraulic pressure. The sum-up of hydraulic pressure will make the main generators work. The basic concept requires hydraulic systems that can help to us to gain some reasonably good mechanical advantages. The hydro-mechanics will convert the mechanical force into hydraulic pressure. The collective hydraulic pressure shall be utilized to rotate the generator shaft.

Hydro Power Invention - No Reservoirs Required

April 11th, 2007 - Alternative Energy Info

A new hydro power technology is being developed by Sarfraz Ahmad Khan of Pakistan. In theory these hydro plants would not require a reservoir and would have a minimal impact on the environment. They could be run side-by-side in rows and would be much cheaper to build, operate and maintain. Sarfraz has high hopes that his ideas could revolutionize hydro power in his country and across the globe. He is currently seeking expert confirmation of his ideas; this article provides a brief summary of his ideas along with some of the 3D images he has created. You can help him by leaving your comments at the bottom of the page, or by joining the discussion that inspired this article.

Turning to the tide for green energy - Tidal Power in Canada

Turning to the tide for green energy

27 Mar 2007

Shannon Moneo, The Globe and Mail

VICTORIA -- The fast-moving tides and deep waters near Victoria were the backdrop for Canadian Prime Minister Stephen Harper's January announcement if $1.5-billion in spending over 10 years to boost Canada's supply of green energy.

Last summer, Vancouver-based Clean Current Power Systems installed a tidal turbine generator near Race Rocks.

Salt water corrodes the metal equipment, and the tides flow like a fast-moving river, which is more taxing on the generator than a slower current.

Other challenges have surfaced. Read more from here @ The Globe & Mail

Nine Vermont (USA) towns urge more micro-hydroelectric projects

Posted on Saturday, March 10, 2007 posted by posted by Ecacofonix @ 11:02 AM

March 10, 2007

The strangulation of government beauracies and regulations have killed the development of small hydroelectric projects.

Nine Vermont (USA) towns urge more micro-hydroelectric projects.

Voters at eight town meetings called on state government to clear the way for rapid development of small hydroelectric projects, but prospects for action appear poor.

By one estimate, Vermont has more than 1,000 dams, many of them abandoned 19th century mill sites. Activists say some of those dams could be used to generate small amounts of electricity without harming the environment.

Complex, lengthy, state and federal permitting processes make those projects financially impossible, according to complaints

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
