I remember when I first saw this. I’m all for cool ideas, but it looked as dumb as the RCA needle-in-a-groove videodiscs. It looked like a classic example of paying ten bucks to save 5 bucks.

Exactly. Solar cells don’t respond well to cracking. Roads crack. I’m not sure who decided it would be fun to drive heavy vehicles over solar panels continuously, but it wasn’t a practical engineer.

My feeling was it was far fetched, but...I keep in mind a lot of things seem far fetched if they are advanced enough. It reminds me of a poster I had on the wall of my office for a long time: ""Any sufficiently advanced technology is indistinguishable from magic." (Was it Arthur C. Clarke?) The picture on the poster was a broadly grinning six year old boy from the fifties or sixties with big earphones, and some kind of apparatus it looked like he made himself...wish I could find it!
