VIII. Uranium radiation and the electrical conduction produced by it

Uranium Radiation and Electrical Conduction produced.109 capillary canal about one half millimetre in diameter, the absorption of water is as great as 18 per cent. of the volume contained per hour.In finely porous rock correspondingly larger absorptions are to be anticipated.Again, the temperatures and pressures given in the above experimenes would be more than reached by, a column of water penetrating a few miles below the earth s surface.Finally, the action of water on silicates will be accelerated in proportion as higher temperatures are entered with increasing terrestrial depth.Eventually, therefore, heat must be evolved more rapidly than it is conducted away.With the above proviso, one may reasonably conclude that the action of hot water on rock within the earth constitutes a furnace whose efficiency increases in marked degree with the depth of the seat of reaction below sea-level.Brown University~ Providence, U.S.A.
