I've been watching this technology for a few years:

I'm not really interested in the panels sitting on top of my traditional shingles, however, if the singles themselves were solar, AND it was cost effective, I would consider doing it. The tax breaks are a scam IMO, like the cash for clunkers program. Someone, meaning other taxpayers are picking up the tab for those tax breaks.

Ultimately, if solar, wind, etc... are going to make it, they need to stand against other energy sources, hydro, fossil, nuclear, before I will consider adopting them. I am certain that when fossil fuels become more expensive, other energy sources will take their place in the market. I am not a fan of having governments picking winners when it comes to the market competition.

If solar roadways are a solution, there are plenty of people, businesses, and governments that will be beating down doors to adopt them. I just hope those governments don't force the taxpayers to adopt over priced solutions to problems that don't actually exist.
