Harnessing the World's Vast Untapped Hydropower Potential

$this->bbcode_second_pass_quote('', 'B')ourne Energy, an energy research and development company based in California, has developed a novel hydropower technology that does not require a dam or reservoir to produce power. Bourne's RiverStar (Patent Pending) river power system, a 20-foot long self-contained energy module, is designed to be sited in-river in long arrays. Bourne plans to build a series of prototypes leading to full-scale demonstrators to promote its utility scale hydropower power systems worldwide. Bourne's new hydropower technology promises to open up vast hydropower potential creating a new age of hydropower that can help move the world toward sustainability.

That actually sounds like a decent idea. Not gonna save the world though. But, I am not really a fan of hydro-power. They fucked up the grand canyon so much.

The Hoover dam is beneficial besides its power generation. It moderates the cyclical flow of the Colorado, otherwise California would experience drought much of the year then get flooded during the meltwater season.

Here in Niagara Falls the hydro electric project acts as a "swing producer" smoothing out the bumps during the daily peak demand period. So hydro-power has its benefits.

THE LA FARGE DAM

$this->bbcode_second_pass_quote('', 'T')he La Farge dam was a very early example of a federal project preparing an environmental impact statement. Numerous environmental concerns were raised. There were a number of endangered species of plants and serious concerns were raised about the dam’s effect on water quality. The US Army Corps of Engineers (COE) made some provisions in the structure of the dam to address the water quality issues and the project was given the go-ahead for completion. By 1975, over half of the dam structure was completed and the state highway from La Farge to Rockton had been relocated. However, costs escalated due to delays caused by the environmental impact statement and modifications made to the plan. In 1975, Wisconsin Senator William Proxmire asked for a re-evaluation of the cost-benefit ratio for the dam and the project collapsed due to that analysis. The project came to a halt in 1975.

A wave generator that does not use a dam ?
I found a video on an "invention" but not so sure if it's the same technology involved

Lower granite dam: Snake River

Unread postby billp » Wed 04 Apr 2007, 20:05:31

Senior citizen was chuckar, quail, hun, and pheasant bird hunting fan in the Palouse [Washington State University] between 1966-80.

Lower granite dam was installed on the Snake River during that period.

Bird hunter trudged the hills above the lower granite dam in pursuit of birds ... and exercise.

Green revolution had just started.

Here's what happened.

Applying petrochemical fertilizer for the green revolution accelerated decomposition of the soil which then washed into the Snake river.

The Snake river is silting-up behind the dams.

Snake river hydropower has problems because of silting.

As well as to Palouse wheat and pea farmers whose land is being washed away.

These farmers may also be suffering a diesel fuel shortage problem soon.

BUT GOOD FOR THE BIRDS!

Problem senior citizen is grappling with is how to get to the birds if there are gas shortages.

In 1973 this worry led to consideration of using a bicycle to go bird hunting and return. More great exercise!

Any moving water can supply power, that much is obvious. Though dams may be invasive, the do vastly increase the potential for power generation over any less intrusive turbines, as well as providing energy storage capacity and the possibility of flow regulation as previously stated. Dammed waterways are in many ways perfect swing producers, having a faster "throttle response" than any other power generators that I know about.

My country's electricity comes almost exclusively from hydro and nuclear, roughly 50/50. All rivers with the biggest production potential are since long dammed up, but a handful were kept pristine, for biodiversity and other "fuzzy" values. Last time I researched the subject, I found numbers suggesting that damming the attractive sites of these waters could increase hydro production by 12%, and damming it all, costs be damned, could lead to an increase of 17%.
I'd rather see more/better nukes, truth be told - hell, throw in a few thousand windmills into the equation to keep the greenies (myself included) happy for all I care, and leave those few measly streams alone. I believe that Swedes and salmon can peacefully co-exist.

Hydro power is scalable to any need level. We could supply all our needs for the next 400 years with just water power alone. Rain will always be a staple in America.

There is nothing new about the technology, it's called a bulb turbine. I think some of the largest installations are on the Rhine.

Rock, do you have any sources you can cite? The generally accepted estimate within the hydro industry is that the US could ultimately double current hydroelectric generation by exploiting all available resources. I'm not sure if that includes the super low-head bulb turbines, but those are really marginal investments for a producer. Various micro-turbine uses are also being investigated, but obviously water storage becomes the limiting factor.

Needs, but not demand.

Rain in the US a staple?
