Brazil, Peru May Invest $15 Billion in 5 Hydro Dams (Update1)
Share Email Print A A A
By Andre Soliani Costa and Alex Emery
Aug. 7 (Bloomberg) -- Brazil and Peru are studying five hydroelectric projects that would cost as much as $15 billion, Brazilian Energy Minister Edison Lobao said.
Peru may consume 20 percent of the electricity from the dams and ship the rest to Brazil, Lobao told reporters today in Rio de Janeiro. Brazil and Peru aim to start operating the dams, which could generate 6,000 megawatts, in 2015, he said.
“We need to have energy, to ensure Brazil’s energy security,” Lobao said. “Whatever exceeds Peruvian needs will be exported to Brazil, which may re-ship the energy to other neighboring countries.”

29 Nov 2008
Existing technologies which use water power, relying on the action of waves, tides or faster currents created by dams, are far more limited in where they can be used, and also cause greater obstructions when they are built in rivers or the sea. Turbines and water mills need an average current of five or six knots to operate efficiently, while most of the earth's currents are slower than three knots.
"field" of cylinders built on the sea bed over a 1km by 1.5km area, and the height of a two-storey house, with a flow of just three knots, could generate enough power for around 100,000 homes. Just a few of the cylinders, stacked in a short ladder, could power an anchored ship or a lighthouse.
Systems could be sited on river beds or suspended in the ocean. The scientists behind the technology, which has been developed in research funded by the US government, say that generating power in this way would potentially cost only around 3.5p per kilowatt hour, compared to about 4.5p for wind energy and between 10p and 31p for solar power. They say the technology would require up to 50 times less ocean acreage than wave power generation.
The system, conceived by scientists at the University of Michigan, is called Vivace, or "vortex-induced vibrations for aquatic clean energy".

The Circular Wind Dam first described in this post may not provide much improvement over the current state of the art.
However, it lays the groundwork for some variations that I think may be very viable indeed.
These variations are presented toward the end of this post, but in case you’re in a hurry, here’s a general idea of the type of machine that we will be working toward:

India hydropower station hits record electricity targets
Shimla-based hydroelectric power company Satluj Jal Vidyut Nigam’s 1,500 megawatt Nathpa Jhakri Hydro Power Station generated a record of 1.14 million units of electricity, against a target of about 1 million units last month.
The previous best target had been just over 1 million units, achieved in July of last year.
The underground power station, located in the state of Himachal Pradesh, generates 36.9 million units of electricity daily
The Indian government has had programs to promote power generation from renewable sources for the last 25 years, but the cumulative power generation from these sources is only around 12,000 MW (see Indian businesses lament lack of renewable energy).

The World's First Hydroelectric Power Plant Began Operation September 30, 1882 >
When you look at rushing waterfalls and rivers, you may not immediately think of electricity. But hydroelectric (water-powered) power plants are responsible for lighting many of our homes and neighborhoods.
On September 30, 1882, the world's first hydroelectric power plant began operation on the Fox River in Appleton, Wisconsin. The plant, later named the Appleton Edison Light Company, was initiated by Appleton paper manufacturer H.F. Rogers, who had been inspired by Thomas Edison's plans for an electricity-producing station in New York.

Green Role Model:
Metro Taxi Is Driven to Save
Inspired by lower operating costs and consumer enthusiasm, metro taxi in denver is switching its entire fleet of 420 cars to hybrid vehicles.
It has already replaced 37 standard sedans—mostly Ford Crown Victorias, rated at 19 miles per gallon by the Environmental Protection Agency—with the Toyota Prius,
rated at 46 mpg.
After the fleet is fully converted, which will take up to eight years, the company says it will save 2.6 million gallons of gasoline annually, or $5.2 million at $2 a gallon.
The change has created some public buzz, too. “A lot of customers now call specifically for the Prius,” says Brian Horvath, fleet manager. “They like the comfort and the quietness and the whole green idea.”

Doctor Elijah has come up with a river power design that he says could provide a decentralized power plant that is portable with an excellent return on investemt. A floating barge with turbines around the perimeter harness the energy of the water flowing by. Rather than try to enter the electricity utility business with all its strident registration obstacles, the company model is to produce electricity by-products, such as hydrogen and distilled water, which are much easier to distribute without bureacratic oversight.A 20 kW prototype has been built from eight sheets of plywood on an aluminum frame."Slow Moving Water.com is the gorgeous cousin of Hydroelectric. cleaner, easier" -- Dr. Elijah Bonesteelhttp://peswiki.com/index.php/Directory:Slow_Moving_Water,_Inc

The new device, which has been inspired by the way fish swim, consists of a system of cylinders positioned horizontal to the water flow and attached to springs.As water flows past, the cylinder creates vortices, which push and pull the cylinder up and down. The mechanical energy in the vibrations is then converted into electricity.
Cylinders arranged over a cubic metre of the sea or river bed in a flow of three knots can produce 51 watts.
This is more efficient than similar-sized turbines or wave generators, and the amount of power produced can increase sharply if the flow is faster or if more cylinders are added.A "field" of cylinders built on the sea bed over a 1km by 1.5km area, and the height of a two-storey house, with a flow of just three knots, could generate enough power for around 100,000 homes.

Fish-based marine power harnesses slow moving water24 November 2008A renewable energy technology developed by a scientist who worked on keeping offshore oil rigs upright can generate electricity even from slow moving water.The new system, which makes the most of vortexes created when water rushes past cylinders, could open up new areas of ocean and river floors to renewable energy creation.University of Michigan professor Michael Bernitsas, who developed an expertise in the vortexes carrying out research on how to minimise their impact on oil rigs and bridges, has developed "a totally new method of extracting energy from water flow".Water rushing past cylinders causes them to vibrate with devastating consequence for the structures they support, but prof Bernitsas' device instead harnesses the vibrations to create energy.According to the developers, the device works in water moving at two knots, compared to the five to seven knots turbines and water mills need to be financially viable.The Vortex Induced Vibration for Aquatic Clean Energy device, soon to be tested in the Delaware River, has used lessons learned from observing fish, which supporters claim will benefit from the technology.Instead of spinning blades which could harm fish populations, the new system will at worst disorient the marine creatures, say backers.The UK has half of the EU's wave energy potential, according to Frost & Sullivan, though this applies to traditional measures and the new technology could see areas previously not considered marine power assets used for generation.http://www.michigandaily.com/content/prof-turns-vibrations-electricity

A series of fishways at dam sites along the river provides passage over the dams.At the Holyoke dam, fish actually are lifted with an elevator in a system developed in the 1950's.At other dams, different systems are used. Each location presents unique engineering problems.
