His technology acheives 5.4% thermal efficency, solar cells are between 12-20% efficency. The benefit of his technology is that it is cheap, but how much cheaper than than crappy solar cells which are 6% efficent?

Interesting setup but the concept isn't entirely new. Kerosene and gas fridges have been around for years. It's rather strange to think of fire keeping your food cold.

I personly think the idea deserves some merrit. With energy bills rising the way they are, I dont think we should dismiss any addition to the consumers money saving arsenal. I don't see truely self sustaining homes being able to survive on only one sorce of engery. Solar energy both light and thermal are free so why not employ both. My only worry is that their end product could wined up alot bulkier then the average consumer is willing to put up with. And from what I could see from the pictures posted that might not be the case.

Dear Folks:

This is the biggest break through in AC I've seen. 1/3 costs, My only question is if there is a maintainence issue with the build up of deposits of any sorts in the channels due to poor water quality.

while there may be maintainence needed i dont think that one should be a problem since it doesnt use watter but a "synthetic fluid with a very low boiling point"

matteran's solution is interesting but
I don't know if you have heard about this company. Hydrogen Technologies Applications, Inc. of Clearwater Florida that has invented a gas generating machine that converts distilled water into a gas they call Aquygen (HHO). Its being used right now for heating, welding & transportation. The generator operates for less than $1.00 per hour. Uses approximately. 5 kilowatts & a quart of water while producing approximately. 1500 liters of Aquygen per hour. This is a new commercial form of hydrogen technology thats ready now & much cheaper & power full then fuel cell tech. Did I mention they also use the gas in their autos an get 50% better MPG. Their web site is www.hytechapps.com phone 727-531-5979 The machines are built and ready for sale NOW. According to physicist Ruggero Maria Santilli in an article published Available online at www.sciencedirect.com HE2131. It's A new gaseous and combustible form of water. You should really be interested in this one

To the above commenter:

I have heard of this HHO, or "Aguygen" it is commonly referred to as Dihydrogen Monoxide. I dont think many people understand the ramifications of the use of such a dangerous chemical, and the proliferation and continued use of Dihydrogen Monoxide as a power source is just beyond belief to me. What some people will do to make a buck.

Just look at the assosciated health risks and environmental damage that Dihydrogen Monoxide or "Aguygen" is attributed to:

*Prolonged exposure to solid DHMO causes severe tissue damage.
*Death due to accidental inhalation of DHMO, even in small quantities.
*Excessive ingestion produces a number of unpleasant though not typically life-threatening side-effects.
*DHMO is a major component of acid rain.
*Gaseous DHMO can cause severe burns.
*Contributes to soil erosion.
*Leads to corrosion and oxidation of many metals.
*Contamination of electrical systems often causes short-circuits.
*Exposure decreases effectiveness of automobile brakes.
*Found in biopsies of pre-cancerous tumors and lesions.
*Often associated with killer cyclones in the U.S. Midwest and elsewhere.
*Thermal variations in DHMO are a suspected contributor to the El Nino weather effect.

There is an excellent web resource aimed at educating the public to Dihydrogen monoxide and its dangers can be found at http://www.dhmo.org/

Someone should do something about this...

The previous poster Sal to be mildy blunt is a moron. That is a spoof site setup by a university professor studying the naivety of people and what it takes to convince typically rational people to believe almost anything. The substance that dhmo.org is referring to is WATER... People please don't blindly accept things as true, that is what got this current president elected.

From looking at the animation, it seems like it would require wasting lots of external "cooling water" (which obviously has to be cool enough to be cooler than the boiling point of this fluid anyway), which is in short supply on hot days. Has anyone taken the cost of this into consideration?

P.S. and if you're going to do that, then why not just use this "cooling water" to cool down your house?
