Energy Harvesting
The Lightning Switch transmitter requires no outside source of electricity. Each time the transmitter button is pressed, the transmitter converts the mechanical energy supplied by the user's finger into electricity to power a radio transmission to a receiver/relay through the use of a piezoelectric generator (brand name: Lightning) originally invented by the National Aeronautics and Space Administration. This technology is described in the 2005 issue of NASA Spinoff magazine.

Famous quotes containing the word energy:
“Just as we are learning to value and conserve the air we breathe, the water we drink, the energy we use, we must learn to value and conserve our capacity for nurture. Otherwise, in the name of human potential we will slowly but surely erode the source of our humanity.”
—Elaine Heffner (20th century)
