The Show-Me state wants to be convinced solar panels can combat winter ice on municipal bridges.
Snow plowing and road salting could be reduced by solar power radient heat system
So it signed a contract to test a solar-powered radiant-heat system on two bridges near St. Louis. The system pumps a solar heated antifreeze solution through tubing in the road deck, melting ice and snow.
The state is among the first in the nation to attempt such a project.
The novel use of solar cells is conceived by Pave Guard Technologies, which will get construction under way in 2010.
Missouri plans to expand the program if it is successful.
