This plant would, he predicted, be 70% efficient and would supply power at half its present cost. Inventor Claude's principle, old to physicists, rests on the fact that water's boiling point is governed by pressure. Lower the pressure sufficiently and water will boil at room temperature. Why not, reasoned Inventor Claude, put warm surface sea water (between 79-86° F. in tropical seas) in a boiler...

...where the pilot cannot see-has been the subject of extensive experiment with highly sensitized altimeters (TIME, Oct. 7) and with auditory radio signals. Last week in Gloucester, Mass., a new line of attack, by which the pilot "sees" the hidden field, was announced by John Hays Hammond Jr., inventor famed for researches in radio. The Hammond plan employs three radio compass stations, a television transmitting station and a minutely accurate model of the airport.
