Supplying Heat with Cold Water
An Italian has evolved a system whereby he claims it will be possible to heat cold rooms and, in fact, supply heating anywhere it is wanted, w'ith cold w r ater. His appliance consists of a rubber bag containing some “special salts.” When heat is required all that is necessary is to add two spoonfuls of cold water to the contents of the rubber bag, and forthwith a temperature of 122 degrees Fahrenheit is produced in the bag. This heat will last for four or five hours, it is claimed. The contents of the bag are sufficient to supply heat, with moderate and reasonable usage, for 150 hours.
