Several sites are running a story on the solar roadway installation in the Netherlands, including phys.org and IFLScience.
However over at EEV Blog is a thorough critical review by Dave Jones which runs through the numbers and finds it doesn't add up as a practical proposal. There's references to Dave's original review of an earlier proposal, for some background on the calculations.
From the associated forum posting:
Dave shows how to go about doing ballpark engineering feasibility calculations for such a project, calculates the expected payback period, and SPOILER, shows why Solar Roadways will never be a viable technology. This time using real measured data from the Netherlands cycleway prototype, and real measured solar insolation data for the Netherlands
Solar roads have plenty of potential problems, such as damage and snow, but theft? Apparently that's a concern, too. China's Qilu Evening News reported that thieves carved out a small (5.9in by 73in) portion of an experimental road in Jinan on January 2nd, a mere five days after its December 28th debut. While it's tempting to suggest this was an accident, officials said the missing segment was "neatly cut," and didn't appear to have come loose on its own.
The segment has since been repaired. An investigation is ongoing, but there aren't any identified culprits as of this writing.
