Submission + - Proposal: Cover highways with a solar panel roof (inhabitat.com)
Caerdwyn writes: An interesting proposal: build a miles-long roof over urban highways made of solar panels. The idea is to make use of otherwise "lost" area to generate power locally. This addresses some of the traditional concerns of large-scale solar projects, specifically their ecological impact if placed out it deserts, losses due to long transmission lines, and dealing with the high cost of land if the project is within the city it serves. Part of this would, of course, have to be a construction methodology which would not make traffic problems worse, as well as what reflections off the panels might do, but at the least this is an interest thought-experiment.
