How Can a Fridge Work Without a Motor? (3d animation) 

I grew up in the Australian Outback where kerosene refrigerators were common. They used a simple hurricane lamp style flame to provide the heat. I never know you could use gas until we got one in a hired caravan for use when on the road and did not have access to electricity. The main problem we had was that it could get too cold and we had trouble with things that should not freeze getting frozen.

Great work, I wonder how much heat does it need?

Thanx for ur effort given for this to all understand deeply

Looks like a bomb waiting to go off.

I have a problem where mine doesn't work very well at high altitude. What would cause this?
