Jul. 12, 1958 - U.S. Helmet Radio designed to use the sun's rays to obtain electric power needed. The U.S. helmet radio currently being developed by the U.S. Army Signal Corps, is deisgned to use the sun's rays to obtain all electric power needed to operate both the transmitter and receiver for as long as a year. Long narrow clusters of tiny solar cells are paced on either side of the crown of the helmet. These silicon wafers power the radio fro normal daylight operation and charge four small nickelcadium storage batteries to supply peak current in daytime and operate the set at night.
