roducing heat by means of Arctic cold is a fantastic but none the less quite practicable idea evolved by Dr. H. Barjou of the French Academy of Science. Dr. Barjou says the water under the ice in the Arctic region is about 70 degrees Fahrenheit. While the air is many degrees less, there may even be a difference of 50 degrees. The unfrozen water could be pumped into a tank and permitted to freeze, thus generating heat, as freezing a cubic meter of ice liberates about as much heat as burning twenty-two pounds of coal. The heat produced would vaporize a volatile hydrocarbon which would drive a turbine. For condensing the hydrocarbon again, Dr. Barjou says great blocks of brine could be used.
Not only would the Arctic regions become comfortably habitable by means of this utilization of energy, contends Dr. Barjou, but heat also could be furnished for the rest of the world.
Now if some one only can discover how to make the Sahara Desert send forth cooling waves, the world will be perfect, temperaturally.
We were invisible!
