The fins work by creating channels along the exterior of the pot that guide the flames further along its surface, keeping them akimbo to the pan and heating it more thoroughly.The fins also transfer heat to the inside of the pot. That is the reverse of fins found on electronics which are trying to get rid of excess heat.
The pan comes out in England, in August and will cost 100 pounds.
The current model will heat water 30% faster than ordinary pans. The prototype heated water in half the time it took an ordinary pan, but was neither practical nor esthetic.
