Waterloo engineers believe it's possible to harvest energy from the sunlight beating down on the province's roads. Photovoltaic panes embedded in the asphalt could be either hooked into the electricity grid or used to directly power streetlights and signs. In winter, the energy they generate could even melt snow and ice, eliminating the need for plowing and sanding.
They face a host of engineering challenges. The panels must be tough enough to bear the weight of an 18-wheeler, withstand repeated cycles of freeze and thaw and provide a durable, safe road surface. On top of that, there's the question of how to transmit the electricity the panels generate. team of experts in civil, electrical and mechanical engineering are currently working together to design and test a solar road panel.
Despite the obstacles, the team expects to have conceptual designs completed shortly. Ultimately they hope to create the world's first "electric highway," pioneering a truly sustainable form of transportation infrastructure.
