A French scientist calculates that in an average day the sun will pour on two and a half acres of ground heat which might be turned into energy equal to the muscle power of 4,163 horses. Mr Mouchot believed that this heat might be utilized and made to do work now done by steam and electricity. He found (says the New York World} that by condensing the heat playing on less than a yard and a-half of ground he could boil two pints of water. By arresting sunshine and condensing it small steam engines have been operated successfully in Paris, but nothing has yet been done to realize practically the great hopes of revolutionizing civilization by using directly the enormous power which comes to us daily from the sun. This power is calculated at that of 216,000,000,000 horses, and a thousandth part of one per cent, of it would run all the factories the world will ever need. The tramways, omnibuses and underground railways in and around London, within a radius of five miles, carry each year, it is claimed, about 453,000,000 passengers.
