Ever had to deal with a power blackout during the hot summer months? Then you know just how important keeping cool can be.
Over on The Good Survivalist we found a great tip to save you money and keep you cool:
Seems every year people die due to heat. Keeping your home cool in the summer can be very expensive if you use your air conditioner. This air conditioner is very simple to make, and can be made in a few minutes if you are handy.Even if you are not handy you’ll be able to make one of these DIY air conditioners. One of the nice things about this air conditioner is that it will give you up to 6 hours of coolness. This thing works so well you may need to put on a sweatshirt! To make one of these babies you need a few simple tools, a couple of 5 gallon buckets, along with a few other items. Everything is shown in the video.
This is called a swamp box. it’s the way movie theaters cooled in the 20’s, 30’s and 40’s. Some old trucks had a similar system in the sleeper area. No ice just water chilled by the fan.
Pretty neat, but you have to have done it before the power quits.

Michael Oonk no buddy. a swamp cooler exchanges sensible heat into latent heat. the result is cool, high humidity air. This is an air conditioner, you are blowing air across a block of ice, the heat energy in the air will be used to melt the ice. This is moving the heat energy from the air, into the block of ice. until you run of of ice of course. You can actually calculate the cooling capacity of this machine. 1Ton of cooling isdefined as the heat of fusion absorbed by melting 1 short ton of pure ice at 0 °C (32 °F) in 24 hours. This is also dehumidifying just like a cold coil would. science baby.
so if it takes 12,000 btu to melt one ton of ice in 24 hours… what is the cooling capacity of this machine which melts 1 gallon of ice in 5 hours. ill be waiting for your homework response in my mail inbox.
total heat does not change with a swamp cooler, the air is sensibly colder but the heat is still contained in the water droplets in the air. it is a constant enthalpy system. Next time I’m over we will setup some experiments and drink beer. its fascinating stuff this.
Dammit Raphael ….couldn’t let me call a t**d a t**d could you.
Look, you even spawned a response from the host!
