Alaska Resort Pioneers Revolutionary Hydrothermal Power

One great thing about true EcoGeeks is that while their opponents are wasting time trying futilely to usefull link bestellen levitra online disprove the problem, they're hard at work dreaming up solutions. A perfect example of this is the Chena hot springs resort located to the nassmc.org northeast of Fairbanks in Alaska. Its engineers and use cialis 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 buying us online viagra 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 shelf parts. It produces 200 kw at a cost of levitra soft gel 5 cents per kwh, compared to 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 best price generic cialis amount of energy in the remaining gas and coal resources. Additionally, the Chena team has a grant to cialis cheap 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 www.rickgenest.com Chena’s unique refrigeration system, which uses a three-pressure system and ammonia-water cycles to chill brine to minus 20 F. Such a system saves Chena $188 a day and limits the use of toxic refrigerants. Lastly, the town of tramadol shipped cod 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 www.worcestercountybar.org work on a project to generate hydrogen using part of 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.

Great article except for the indian viagra first sentence. The design mentioned in the article is smart regardless of future climate change. These are the ideas that will work because they are financially feasible. The tact that we must save mother earth regardless of the cost will not cut it in real llife regardless of future climate change. We need pragmatic ecogeeks that can get results and not just mumble jumble.

Unique? What unique?

Klamath Falls, OR, where I misspent much of my youth was heating homes and http://revistaneon.net/generic-cialis-canadian buildings as early as the late 19th Century or early 20th Century.

Greenhouses, aquaculture and one large mushroom farm in Harney County in southeastern Oregon have been using low temperature geothermal waters for many years. That is far from unique.

Husavik, Iceland, adds heat to geothermal waters with a garbage-burning facility for a 2MW power plant utilizing the kalina cycle to generate electricity.

I asked the executives of Polaris Geothermal, which has an interest in the kalina cycle whether they might be able to http://dependablehealthcareservices.com/pa/joycejacob/buy-viagra-in-canada match or beat United Technologies novel approach with less efficient organic rankine cycle. They were very impressed with what had been accomplished at Chena but were non-committal about comparisons with the particular feat.

Thank you very much for the article. The hydrogen mix is new to me.

Best, Terry
