Did you ever remove your A/C?

Use your head and think about what you just said

"the guy in the video." WHO IS this "guy?" What does HE know. What is his agenda? Is he telling the truth, or just a schill for the company?

What you have here, folks, is a box full of ice water. OK?
This thing should have a great big "Ronco" label on top and "be sold only on TV"

"Calculations?

I used to install and maintain / repair HVAC / R systems. I know and understand the basics of thermodynamics (certainly of a bucket of ice) and swamp coolers.

OK, so here, this is from their own website........ this is a QUOTE

=================================

"A MightyKool 12-Volt "Ice Water" Model uses from 10 to 20 pounds (4.5 to 9 kilograms) of ice PER HOUR or more to produce between 5,000 and 8,000 BTU. "
=================================

PLEASE READ THAT AGAIN!!!! This means that for every hour you are tootin' down the road in the hot summer heat, with that marvelous unit outputting a whole "5-8000 BTU" of of "cooling" you will have to stop and buy ANOTHER 20 lbs of ice somewhere.

A typical auto A/C is probably somewhere around double that BTU rating by the way, maybe more on some vehicles

OH MY GOD I HAD NO IDEA NOW I'M GONNA DIE!!!!!!!!!!! lol 'chill' out :glasses7:

I already knew all this. I'm a mechanical engineer so I'm not unaware of how this works. You put 80 lbs. of ice in a cooler with a bit of water just to get the pump working; latent heat of melting ice is 144 Btu/lb times 80 lbs is 11,520 Btu just to get the ice melted not considering the latent heat of the cold water itself which is significant. Assume a Duster has about 100 cubic feet of interior volume (very large estimate it's probably closer to 75). A highly simplified calculation for maintaining a room temperature of 55°F (very cold), (volume times 6) + (# of occupants times 500). With that you get 1600 Btu/hr; now we know in a car it will be very different since you have an engine producting heat which is coming through the firewall and up from the floor and crappy old sealing designs with hot outside air seeping in so that calculation is kinda useless, let's assume around double at 3000 Btu/hr required. That still gives you almost 4 hours of steady cooling before all the ice melts; then you still have very cold water near freezing temperature that will have to increase in temperature by what, 40°F before it's not cooling anymore (another 3500 Btu or so)? Then on top of that this MightyKool thing has combined heat exchanger AND evaporative cooling which a normal A/C or simple swamp cooler doesn't do. So in essence, 4 hours till the ice melts then another maybe 3 hours of very gradually weakening cooling effect.

Is it as powerful as a real A/C system with a compressor, refrigerant etc.? HELL no. Is it a cost-effective alternative to paying a couple thousand dollars and 10-20 hours (if not more) to install an aftermarket A/C system that can only be used in the car it was installed in? I think so. I'm not even dead-set on it, I would only consider it if I was for sure planning a cross-country road trip in summer time because where I live the summer is bearable.
