- From California comes the almost eternal light bulb
-
-
- Want a light that will outlast the century and illuminate
- your children's homework from kindergarten through high school?
- Two small Silicon Valley companies unveiled an electronic bulb
- that uses radio waves to produce 20,000 hours of light, or about
- 14 years of average use. Intersource Technologies Inc. and Diablo
- Research Corp. said their new E-Lamp, which fits standard
- sockets and uses 75% less juice than ordinary bulbs, will cost
- from $10 for residential use to $20 for commercial applications
- when the bulbs become available next year.
-
- Intersource estimates that a single E-Lamp could save
- homeowners anywhere from $50 to $100 in electric bills over a
- 15-to-20 year period. A standard 100-watt incandescent bulb
- costs 75 cents and burns as long as 250 days. With a standard
- bulb, only 5% of the electricity is converted to light -- the
- rest is wasted away as heat. "Until now there has been no
- substantial improvement in lighting since the time of Thomas
- Edison," boasts Intersource president Pierre Villere.
-
- The big name in bulbs, General Electric, claims to have
- developed equivalent technology two decades ago, but chose not
- to pursue it. In 1986 GE executives toured Diablo Research and
- examined the E-Lamp project before Intersource obtained the
- marketing rights. But GE dismissed the idea that there was a
- market for a $20 light bulb.
