Last week the Indiana city of Scottsburg made a bet on the future of its street lights with a little-known technology called LEPs light emitting plasma.
This year's contests include the largest-ever plasma screen (150 inches), the largest Organic Light-Emitting Diode TV (a new bright and energy-efficient screen), the first functioning laser television and the first TVs that receive high-quality wireless streaming from a high-definition signal.
Now 120 families in this remote spot pay just five cents per day to get light and drinking water, plus juice for a community-shared mobile phone, plasma TV and Internet connection.
