Air gets very hot when it is compressed under high pressure. A classic example would be the heat that is created when one uses a bicycle pump. But when the air is compressed in a firepiston it is done so quickly and efficiently that it can reach a temperature in excess of 800 degrees Fahrenheit. This is hot enough to ignite the tinder that is placed in the end of the piston which has been hollowed out to accept it.

I wanna see if that potato will put enough charge in a mobile phone for 1 call , I think possibly more like 5 potato's over a couple of hours might do the trick.
I'm defiantly remembering the fire one though... Good job I'm no arsonist!! I can imagine CSI missing that cremated potato in the burnt out house
