An Idaho couple, Scott and Julie Brusaw, recently started an IndieGoGo campaign to raise money for their project, Solar Roadways, which wants to replace asphalt roads with high-strength glass-encased solar panels and LEDs. The panels could potentially light up, generate electricity, melt snow, or charge electronic vehicles. The government, however, would still need to test the roads, and cost estimates are unclear. The project currently has about 47,000 funders.
