Twisted SWCNT is still mostly a concept. Doesn't even have proof of concept in the lab. According to people involved in it, it may take a couple of decades to go to market. But I agree, it would be great to have " wind up" cars, for example.

Business idea: form dense shipping containers of addressed arrays of [twisted SWCNT, rhombohedral trilayer graphene, or double-gated graphene,]? They would need: anodes, industry standard commercial and residential solar connectors, water-safe EV charge connectors, and/or "Mega pack" connectors to jump charge semi-trucks from a container on a flatbed or a sprinter van. Branded, stackable Intermodal shipping containers with charge controllers It's probably already possible to thermoform and ground biocomposite shipping containers, with ocean recovery loops? Bast fiber anodes for super capacitors are inexpensive, and there may be something to learn from their naturally branching shape. https://www.google.com/search?q=bast%20fiber%20supercapacitor%20anodes https://www.google.com/search?q=bast%20fiber%20supercapacito...

  Yes, obvious once. Only light years away, I'm afraid. Try and get funding for that. GLWT
