Another slant to electric vehicles. Battery swap stations. (Page 4/4) williegoat DEC 14, 07:37 PM quote Originally posted by maryjane: There have been all kinds of 'experimental roads' over the decades. Some with a wire buried that emitted a special signal a modified car would follow, others that checked your speed, one with ground up rubber tires in it (did they make tires out of concrete since the road was rubber?) and at least one in California that had ribs on top of it that 'played' a short (sort of) musical thing if you drove on it at a specified mph. We have a lot of rubberized asphalt around here. It makes for quieter roads and is a great use for old tires (don't tell rinselberg). Twenty years ago, I was the Safety Director for a small flatbed carrier and we hauled a lot of that stuff in super sacks. It is almost like powder, much more fine than I would have imagined. 82-T/A [At Work] DEC 15, 09:17 AM I really do think that hot-swapping can be a thing, but I think it'll have to be very specific. Weight / size, and cost are going to be a concern. Ultimately, I agree with what Cliff and others have said that fast-charging will probably be the way... but the infrastructure just sucks here... and we spend so much money on other things... even in the infrastructure bill, so little of it was actually for infrastructure. I'll save that for the other forum though. BingB DEC 16, 09:08 AM quote Originally posted by williegoat: We have a lot of rubberized asphalt around here.

They super freeze the tires in liquid nitrogen and then "shatter" them to separate the rubber from the wire. That is why it is more "powdered" than "shredded" rubber.
