Sarnoff lab in Princeton just developed a neat device. They made small
hollow plastic beads, coated the inside with phosphrus and filled the cavity
with radio active tritium. The wavelength of the plastic contains the
radioactivity. The tritium excites the phosperus making the beads glow.
They will be placed in lap top screens to produce light with an array of
photo voltatic cells to use some of the light to run the computer, thus
reducing the weight of the battery from two pounds to one ounce. The beads
glow for 30 years.
