This article presents two ideas for the roads of the future that use solar power and magnetic induction to energize transportation in the coming decades. The Solar Roadway was developed with the idea that a layer of concrete or asphalt used on regular roads could be replaced with "solar cells beneath a layer of glass." Installed on all U.S. roads and operating at just 15% efficiency, this could meet "more than four times our current electricity needs." Magnetic induction would be used in a system that keeps electric buses charged wirelessly through power-transfer systems in the road.
