To underscore how safe the system was, the host of the BBC science program “ Bang Goes the Theory ” stuck his face fully into a power beam. The receivers for optical power transmission are specialized photovoltaic cells designed to convert a single wavelength of light into electric power with very high efficiency. At the U.S.
His noctovision used infrared light to see objects in the dark, which some experts claim was a precursor to radar. John Logie Baird [shown here] used the heads of ventriloquist dummies in early experiments because they didn’t mind the heat and bright lights of his televisor. But Baird earned his spot in history with the televisor.
