in 2012, designboom covered the first prototype stage of american electrical engineer scott brusaw’s system of solar powered roads. conceived as an initiative to change the face of national highways by re-purposing them with photo-voltaic panels, the idea for ‘solar roadways’ was to introduce smart streets capable of directly inputting energy into ‘the grid’. if realized, the concept could essentially power an entire country with the generated electricity.

now in it’s second prototyping stage, the project has been further developed as a modular photovoltaic (PV) paving system that can withstand the heaviest of trucks – up to 120,000 kilograms. the plan would see the ‘solar road’ panels installed on highways, parking lots, driveways, sidewalks, bike paths and even playgrounds.

the system is based on centralized power stations, and distribution is handled through transmission lines and relay centers. each panel has its own microprocessor, which communicates wirelessly with the surrounding panels – they monitor each other for malfunctions or problems.

electric vehicles will be able to charge with energy from the parking lots and driveways, and after a roadway system is in place, mutual induction technology will allow for charging while driving.
