Your average asphalt road costs about $1 to $2 per square foot. Just the RGB LEDs in a single panel of solar roadways, even if purchased wholesale, are enough to make this more expensive than traditional roads. Add to that the cost of the photovoltaics, the microcontrollers, the tempered glass, and the cost of the base that you set these into and these are going to be more expensive than traditional roads by a few orders of magnitude. And let's not get into maintenance costs. Meanwhile you could just put ordinary solar panels with heliostats on freeway medians that are far more effective at power generation for a fraction of the cost.
This is a scam, pure and simple.
EDIT - Since I'm probably going to get downvoted by Solar Roadways fans, here are a few examples of how much RGB LEDs cost direct from the factory. Prices range from $.02-$.15 cents per bulb depending on the size, quantity ordered, and other factors: http://www.alibaba.com/product-detail/Factory-dir... http://www.alibaba.com/product-detail/5mm-round-long-feet-2013-newest_787275275.html[3] http://www.alibaba.com/product-detail/8mm-rgb-led...
With 44 bulbs per road panel that works out to a minimum of $.88 per panel or as much as $6.60 per.
The cost of the microcontrollers will be somewhere from $.10-$1 per chip, assuming they use some form of STM microcontroller (assuming an STM would be enough for their needs, otherwise it would get much more expensive). And that's not including a power supply or a wireless antenna or any of the other components they need in addition to the chip itself.

Det er en grunn til at INGEN seriøse investorer, solcelleindustrien eller myndigheter har kastet seg over denne idéen. Disse har holdt på i garasjen sin siden 2006 og må gå til lettlurte folk som tror at alt som skinner er gull for å få støtte til det de driver med.
Vi klarer ikke engang å holde BILLIGE asfaltveier ved like i dag, men solcellepanel veier som koster mangfoldige ganger mer skal vi hive oss på?

Skjønner ikke hvorfor man tror dette er en så fantastisk idé når det vil være 3 ganger så billig og dobbelt så effektivt å sette disse solcellene en hvilken som helst annen plass enn på veiene våre. Veier er dårlige solcellepanel og solcellepanel er dårlige veier.
