Ice Bomb
It was reported that there was interest shown in a bomb in which the thermal properties of its reaction were endothermic - that is, intense cold would be produced on detonation instead of strong heat.
The purpose was supposed to be the freezing of large areas - maybe a mile radius from the site of detonation - and the quick destruction of all living beings from the affected area which would soon recover. The effect is the same as that of a neutron bomb - removal of all life forms without destroying the buildings. No efforts were ever made to even test the possibility of such a device. It was a completely impracticable idea.
