Oh swell...just another way to set cars on fire
It would be a neat trick if it could work. I suspect though that UV degradation of the plastic would reduce millions of square miles of it to rubble, and a lot of problems with water and salt intrusion.
Catching that degradation and replacement before the voltaic cells are damaged would be a very intensive effort in my opinion.
Still, it is thinking that’s definitely outside of the box. I’ll give the couple that.
So...what happens should we have an earthquake?
