Physics students: They came up with an environmentally friendly, economical air conditioner
What's their stock symbols?
This sounds like a good one.
its just an air chiller uses pelts. They fail to note that Pelts use a good deal of energy themselves. So less drag on an engine cause of no air conditioner but more drag and wear on alternator. I'd bet it is still a better option, just my note on it.
Bring it to houston to do the real world test,,,
105 degree day,,,90 % RH ,,windows rolled up all day
4:30 in the afternoon,,
we'll see how good it works,,,,
the other issue is this, Peltiers aren't magic, the heat has to go somewhere. So you need cooling for the hot side of the peltier. And the hot side of a peltier gets hotter then the heat it removes from the cold side.
Jenn called it interesting. By the way, she's currently in school for her doctorate in physics.
Makes ya think don't it?
My question is whether there is a practical application, or is this the latest "wonder invention" that won't work in the real world?
Thats in my state and I didn't even here about it. What are those pelets things? Could you use it in your house or make a portable one?
Pelts use a ton of electricity. They are used to cool some computers, but the require 25 amp power supplies. The back sides get blazing hot so you must dump that heat somehow. They average about 17% efficency.
Pelts are used in some of those 12 VDC RV coolers. "Kooltronic" is one brand name. Those that can only get you ~40* cooler than ambient. So if it's 100* outside, your beer is getting warm.
most are about 40mmx40mm so they are already far more then portable. Just a matter of getting enough power to them. As noted, many use quite a bit of power.
Seriouslly, I'm not impressed by what they did. They just took an existing product(used for cooling things off) and put it into a case of sorts with some fans to cool the hot side(sounds like they made that more difficult then they needed by converting a hair dryer from AC to DC. I was cooling computer processors with Pelts when I was 14.
If someone can explain to me why what they did was so great, I'd love to know. I of course did not read the full article(yeah I likely missed the big point by that fact, but I'm lazy).
Stop wondering. I learned long ago that the simplest invention can be revolutionary if no one's ever done it before.
Even if people have thought about it, but never actually got from point A to point B with the idea.
