hey roger
enlighten us
please provide us with a link to creditable source

i don't really believe that make fire with ice thing, if you can enlighten me, i'll give you a rate of 10
 
A gas refrigerator uses ammonia as the coolant, and it uses water, ammonia and hydrogen gas to create a continuous cycle for the ammonia. The refrigerator has five main parts:

Generator - generates ammonia gas
Separator - separates ammonia gas from water
Condenser - where hot ammonia gas is cooled and condensed to create liquid ammonia
Evaporator - where liquid ammonia evaporates to create cold temperatures inside the refrigerator
Absorber - absorbs the ammonia gas in water
The cycle works like this:
Heat is applied to the generator. The heat comes from burning something like gas, propane or kerosene.
In the generator is a solution of ammonia and water. The heat raises the temperature of the solution to the boiling point of the ammonia.
The boiling solution flows to the separator. In the separator, the water separates from the ammonia gas.
The ammonia gas flows upward to the condenser. The condenser is composed of metal coils and fins that allow the ammonia gas to dissipate its heat and condense into a liquid.
The liquid ammonia makes its way to the evaporator, where it mixes with hydrogen gas and evaporates, producing cold temperatures inside the refrigerator.
The ammonia and hydrogen gases flow to the absorber. Here, the water that has collected in the separator is mixed with the ammonia and hydrogen gases.
The ammonia forms a solution with the water and releases the hydrogen gas, which flows back to the evaporator. The ammonia-and-water solution flows toward the generator to repeat the cycle. [/b]

How a RV refrigerator works
 
Actually, this works. My father demonstrated this on a Boy Scout backpacking trip. It took some doing, but he was able to ignite paper with a lens he made out of ice.

They say to boil the water when you "practice" because tap water is full of air. Lake water or natural ice wont be.

Assuming you were in the frozen tundra without fire, how would you first boil the water to get the ice clear? 😕


my thoughts exactly, also you wouldn't get the "optics" on it to a good enough level of perfection to get a small enough focal point to cause ignition. another thought i had was wouldn't the sun start to deform the optics as soon as you started to use the lense and it started to melt?

He says to boil the water when practicing because more than likely, you'll be using aerated tap water.

And no, the lense wont melt if you're in below freezing temps.

?

In my experience, when someone takes a series of photographs documenting some procedure, and the series abruptly stops right before it would be demonstrated that the procedure was a success, it's because he failed.

In order to work you'd have to have some very "clean" Ice w/o particles or ait pockets and be an expert Ice Shaver since both side must be equalateral and at the proper curvature. You're essentailly correct no way in hell your average person could do this. Bring the mathces next time.

Hey Chuckie, I'm calling you out, where the hell is my ten.

What are the other four?
1. A magnifying glass (very simple)
2. Flint (very difficult)
3. Magnesium striker (simple)
4. Rubbing sticks with hands or bow (very difficult)
5. Fire by ice (extremely difficult)
