Alaska Resort Pioneers Revolutionary Hydrothermal Power

One great thing about true EcoGeeks is that while their opponents are wasting time trying futilely to disprove the problem, they're hard at work dreaming up solutions. A perfect example of this is look here canadian pharmacy cialis prescription the Chena hot springs resort located to the northeast of cialis price in canada Fairbanks in Alaska. Its engineers and canadian drug viagra soft entrepreneurs have cooked up not one but a bevy of eco-friendly technologies that make sense from a financial, environmental, and social perspective.

At the core of their efforts is a low-temp hydrothermal reservoir, which contains 165 F water. This is “low temp” as in the past it was thought that only 300 F reservoirs or higher would be effective for producing power. However, lead engineer Gwen Holdmann and her team devised an innovative power generator, which uses vaporization of refrigerant to drive a turbine, instead of water vapor steam. The refrigerant is then condensed using the naturally cold ground water, located away from the hydrothermal source.

The plant cost a mere $2.2 million to build as it uses all off the usefull link cialis discount prices shelf parts. It produces 200 kw at a cost of 5 cents per kwh, compared to tramadol earnestly online the former costs of 30 cents per kwh when using diesel. The design is projected to pay for itself within four to five years. Hydrothermal power is very promising, as it is estimated that the water beneath the Earth’s surface holds 50,000 times the amount of viagra discount pharmacy energy in the remaining gas and coal resources. Additionally, the Chena team has a grant to build a similar design to take advantage of waste water from oil production, which is at a similar temperature. Experts estimate that oil waste water employed this way could produce 6,000 to 11,000 megawatts of electricity. This would both reduce energy costs and prolong the lifespan of dwindling fossil fuel resources.

Not to be forgotten is Chena’s unique refrigeration system, which uses a three-pressure system and ammonia-water cycles to chill brine to pfizer cialis cheap minus 20 F. Such a system saves Chena $188 a day and limits the use of toxic refrigerants. Lastly, the town of Chena is literally going green; it has used the hydrothermal resource to devise a unique hydrothermal heating for both the buildings of the city, and a special 4,300 square foot greenhouse. The greenhouse allows delicious produce to be grown year round at virtually no cost.

Bernie Karl, Chena’s owner, isn’t done yet. He’s putting Holdmann to work on a project to generate hydrogen using part of cheap viagra the hydrothermal electricity. This hydrogen, mixed with propane, will fuel Chena’s vehicles. The idea of using a hydrogen propane mix is considered very doable from a scientific standpoint according to Holdmann – it simply hasn’t been done yet. So Chena is looking to pioneer the way yet again, this time in a new frontier, the automotive fuel market.

New Technique Easily Locates Geothermal Power

Geothermal energy represents a huge but largely untapped resource. Estimates are that the geothermal potential in the United States could provide 3,000 times as much energy as the country currently needs. But finding appropriate locations with good geothermal potential has required exploratory drilling which is very expensive.

Two researchers at Lawrence Berkeley National Laboratory have now discovered a low-cost method for identifying appropriate locations for geothermal potential that does not require drilling. Instead, they test the groundwater and examine the ratio of two helium isotopes in the water. One isotope is more prevalent in the Earth's crust, while the other is more prevalent in the mantle. The presence of more of the mantle isotope is correlated with locations where the mantle is closer to generic cialis super active the surface, and thus sites with geothermal potential.

Some nations are already making extensive use of geothermal energy, but those are the obvious candidates like Iceland and New Zealand. However, geothermal energy is also part of the energy mix that Google recently announced they would be supporting. So this technology may find its way into wider application sooner rather than later.

Glitnir Gets Ready to Push US Geothermal

Geothermal energy isn't one of the most discussed forms of renewable energy, but a lot of just try! buy cialis from canada smart people are betting that its boomtime is just over the horizon. The Glitnir Bank of Icealand just decided they would loan out $1 billion dollars to U.S. companies building geothermal energy plants.

If anyone knows about geothermal, it's Iceland. They're the only country in the world that runs on 99% renewable power, and 30% of that comes from geothermal (the rest from hydroelectric).

Glitnir has already made a few investments, but the bank is canadian healthcare estimating that investments necessary to service current projects are around $9 billion, and that the overall need for investment to fully capitalize on the trend is roughly $40 billion. There's no doubt that geothermal has a huge part to play in the future, and it looks like Iceland is getting an early foot into the door.


900 Acres of Canadian Solar

A California company is preparing to install a massive solar installation near Sarnia, Ontario (across the river from Port Huron, Michigan) that will be the largest photovoltaic solar installation in North America. Currently, the largest installation in the world is a 12 megawatt facility in Germany. In the United States, a 15 megawatt facility was recently announced to canada viagra no prescription begin construction on an air force base in Nevada. However, the Canadian facility will eclipse both of these, with a capacity of 40 megawatts. It won't necessarily be the world's largest solar farm, however. Large facilities are currently being built in California and Germany.

The OptiSolar Farms Canada Inc. solar farm will cover nearly 365 hectares (900 acres). Sarnia is close to major grid pathways, making it easy to tie the power produced by this solar farm into the North American grid. It is also a relatively southern location (for Canada), which gives it good solar access.

Part of the selection of the Canadian site was due to the premium for solar electricity that the Ontario government is currently offering (currently 42 cents per kilowatt hour).

"The company hopes to break ground in 2008 after getting the necessary municipal zoning approvals and building permits. It has already purchased the real estate it needs, mostly low-value farm and industrial land, and has full backing of the local community."

The Sarnia solar facility is buying viagra in uk expected to be online and fully functioning in 2010.

Nevada Geothermal Production to Quadruple

nevadageotherm We're into lots of generic cialis paypal payment alternative energy generation methods, and we've talked about solar and wind power extensively, and to 100mg tramadol a lesser extent about other methods such as tidal power. But here's a bit of news about one we don't talk about as much: geothermal.

According to a Geothermal Energy Association report (pdf), the State of Nevada is going to be expanding their geothermal power generating capacity to over 1000 MW within the next 3 to 5 years. This would be sufficient to provide 25% of the state's total power needs.

Nevada currently has over 200 MW of geothermal energy production in place. More speculatively, the report also indicates that Nevada could build nearly 3000 MW of generating capacity by 2025. This isn't a technology that can be applied everywhere, but then, some places are not well suited for wind power or solar, either.
