Energy efficient alpine cooking pot

So this is yet another idea which might save some fuel you need to carry up steep mountains - it should improve the cooking speed with more than 50% efficiency.

Here is a picture of the device:

It works this way: the pot has double walls, and a hole in the bottom of the outer wall. The heat generated by the fire, is filling the walls, thus increasing tremendously the surface heating the water. The second picture on the right shows the bottom hole, with protectors allowing smaller stoves to be used.

As you can see on the Top view image, there are 4 microscopic, very small openings for the hot air to escape the double walls - so current of hot air should go up and be kept hot at all times.

Feel free to use it, patent it, produce it - I don’t have the money to patent it, so it’s better someone else do it .
