Sun refuses to be harnessed, Washington, D.C., September 8. The scheduled exhibition of Dr. Charles G. Abbott's sun ray machine was ruined today because there was too much sun. The intense heat, after being concentrated melted the solder connections. Dr. Abbott, the inventor, then went ahead to explain his device which is said to be capable of operating a half-horsepower steam engine by the sun's heat. The exhibition was held in honor of some of the delegates to the Third World Power Conference which is now being held here
