The advance of solar energy is linked to the surfaces on which panels can be stuck, and a new project adds roads and highways to the list.

Some engineers in the US have launched a fundraising program for advanced ‘solar roadways’.

The solar road plan uses interlocking hexagonal segments covered with a specially toughened and textured glass, beneath which sits a solar panel.

The potential roads of the future also feature a series of LED lights and a heating element to keep ice and snow off during winter.

The LED lights can display a range of information to replace conventional traffic lights, offering constantly updated safety warnings and guide lines which can be changed for differing traffic conditions in real time.

The system uses a trench running down one side to hold conduit cables for the power supply and controls, and the designers say a network of digital sensors would be installed to monitor maintenance needs across every metre.

The idea for a huge new decentralised power grid has come from just two people, Scott and Julie Brusaw.

The couple have taken to Indiegogo to drum up their next round of funding. 

They are asking for $US1 million to hire materials scientists, civil and structural engineers to further develop the panels from an idea to workable project.
