The Solar Roadways crowdfunding campaign on Indiegogo has been extended to June 20. Indiegogo's most popular campaign ever, the Solar Roadways campaign has been able to attract record-breaking contributions exceeding 38,000 from all 50 states and 42 countries around the world.

The brainchild of Sandpoint, Idaho couple Julie and Scott Brusaw who have raised more than $1.8 million dollars on Indiegogo after getting started with a small federal grant, the Solar Roadways initiative has the potential to change the way the nation’s millions of miles of roadways and other surfaces are utilised by turning them into power sources.

In addition to creating a new, clean energy source Solar Roadways will also: improve road safety by providing LED lighting that replaces paint and can be changed at the touch of a button; prevent accidents by providing advance illuminated warning of animals or debris on the road; and create an environment-friendly way to melt snow without salt and sand.

Indiegogo launched in 2008 as the world's first crowdfunding platform and is dedicated to allowing anyone, anywhere to fund what matters to them.
