Default Another "free energy" scam - the Coolsurge A.C.

Saw this today in one of those cheesy full-page newspaper ads "disguised" as a headline-worthy news article, with "advertisement" in very fine print in the page margins. Can anyone spot the little thermodynamic conundrum inherent in this "little cooling miracle from the China coast"? From the website

The Cool Surge eco-friendly air cooler is a work of engineering genius from the China coast so advanced that no windows, vents or freon are required. It is as easy to use as a baby’s vaporizer and even includes the four hour extra cooling power of the glacier ice blocks. It uses the same electricity as a 60 watt light bulb, yet it blasts out ice cooled air. The hi-efficiency motor cools the air around the unit up to ten degrees so you’ll instantly feel cool and refreshed. The 3 cooling levels and auto shut off function put all the comfort controls right at your finger tips. It’s so impressive that it even comes with a full year Money Back Guarantee.
Note: careful parsing of the ad-blather reveals what the "secret cooling miracle" really is.

My instant reaction was "ice cooled air", though I'd spell it "ice-cooled air". Either I'm missing something or it's an unusually easy question.

There is no need to mention "ice" twice unless the thing needs pre-loading with ice before it can work a stated. It would seem it comes with some "glacier ice blocks" that are presumably filled with water and subsequently frozen somehow before being placed into the thing.

Correct - the thing requires you to provide it with blocks of ice, which it then blows air over using a "high efficiency fan". Amazing technological breakthrough, that. Perhaps it's just a technicality, but I don't see any mention of a requirement for an "auxiliary refrigeration unit" in the advertisement. Nor mention that unless you live next to a glacier or frozen lake, use of said auxiliary refrigeration unit in conjunction with the CoolSurge will actually have a net *warming* effect on the interior of your home, in contrast to a conventional AC unit, which at least has the "low-tech" feature of blowing the hot air *out* of the house.

Actually it looks to me like an evaporative cooler.These have a reservoir to top up with water.You could add normal tap water and get a noticeable cooling effect although not as much as with an air-conditioner. There is no auxillary cooling unit to cool the water in the reservoir.

Not sure how they are going to stuff the 4 glacier ice blocks into the small hole for the reservoir though.Most of the webpage looks like it was written by a marketing department that has never seen the actual product.

Yesterday I heard this exchange:
"He's as cool as a cucumber"
"That's been in the fridge".
I assumed that the tennis commentator concerned
was aware the cucumbers were not immune from
acquiring the ambient temperature.

And often marketing is a poor translation. And the translator is only mechanically familiar with the target language, but not the culture.

I recall reading that a certain category of vegetable/fruit, including cucumbers, has the property of remaining noticeably cooler than ambient temperature for a while after harvest (and this was the origin of "cool as a cucumber"). I think this was attributed to a particular mechanism of moisture evaporation in those vegetables/fruits.

However, I am unable to quickly locate any such statement.

Well it seems Steorn has not yet died.

Hmm, "next summer" never comes, so I guess they are safe to continue developing forever.

And indeed they live on. Is seems soon they will be giving talks around the world.

What is there to talk about? They never say anything anyway, let alone actually showing anything.

"Perpetuum Gullibile"

LOL, mysterious "technical difficulties" keep them from doing the simple "lightbulb test" [or any similar sanity check] for years on end despite the "fact" that have "robust" demonstrations of their claims.

Anyone stupid enough to invest in this deserves to lose all their money.
