Addressing a joint meeting of the Institute of Radio Engineers and the American Institute of Electrical Engineers on his latest discoveries, the inventor said of the proposed radio lighthouse:
"By means of the revolving beam of electrical radiation it is possible for ships when within a certain distance to ascertain in thick weather the bearing and position of the lighthouse.
"It seems to me that it should be possible to design apparatus by means of which a ship could radiate or project a divergent beam of the short wave rays in any desired direction, which rays, if coming across a metal lie object, such as another steamer, would be reflected back to a receiver on the sending ship and thereby immediately reveal the presence and quickness of the ship.

"The thick weather."
Marconi's radio searchlight bears little resemblance to the battleship searchlight. It is rather a special arrangement of wires on towers or masts.
During his lecture, Marconi exhibited pictures of reflectors resembling the weird apparatus pictured in imaginary tales of the conquest of the world by Martians. Through the use of these reflectors at both ends, clear speech was exchanged during experiments over a distance of ninety-nine miles, he announced.
