A campaign to manufacture "solar roadways" has racked up over $1.8m of funding on Indiegogo.
According to the couple who have set up the campaign, solar roadways are a modular paving system of solar panels that can withstand the heaviest of trucks.
The page explains: “These Solar Road Panels can be installed on roads, parking lots, driveways, sidewalks, bike paths, playgrounds... literally any surface under the sun. They pay for themselves primarily through the generation of electricity, which can power homes and businesses connected via driveways and parking lots. A nationwide system could produce more clean renewable energy than a country uses as a whole.”
The campaign, which has raised more money than any other on Indiegogo, had originally aimed to make £1m.
