It would work if you used about 1000 lbs of ice over a 24 hr period (6000 btu/hr) for a small cabin or 2000 lbs for a larger one (12000 btu/hr)!!!!!

If you was to pump lake water through a heater core, you'd have to get water from deep below the surface.

Why use ice...wouldnt dry ice be a better choice?

Dry ice would be awesome until the CO2 displaced the O2 and you woke up dead

I would think dry ice might work, it dam near freezes stuff. Would it really kill you? I know you can use it in a drink!

Please do NOT use dry ice!!!!!!! Have you seen how well CO2 fire extinguishers work????? It will do the same thing to you!!!!

saw this on tv the other night,i wonder how well it will work in a boat? they said it only draws like 800 watts..

edit,,i just read that it used 4 ice packs to cool.

LOL!!

That thing is still cool for 300 bucks.

I have one and have used it a lot. I works better with a 2 2 liter bottles with water in them frozen last longer than just bags of ice and it makes the cabin cooler.

I have one that I use in the airplane & it does work and it works well, however it doesn't cool like a normal air conditioner would. The ice usually will last me for taxi, climb-out & up to altitude when I shut it down. I then fire it back up during the last 5000' of decent and when taxiing.
It won't last all night. You get about 40 minutes of cool blowing on you. Just enough to keep you out of the miserable hot range.
