Apparently, resin is manufactured in Texas
For many of the same reasons glass is made in Minnesota, like as not.
And, the petroleum byproducts and waste material are near the other petrochemical plants. And, those materials need all kinds of eleaborate storage to maintain pressure, temperature, etc.
The "fallout" from that one week of absurd spring Winter still crops up. Was at my retina doc and the vinyl base and all the gluee-down carpet were ripped out of their new-in-December office. Turns out the sprinkler system froze and left 3-4" of water i nthe entire office. And, guess what, vinyl base supply is down due to the vinyl plants around Houston still being in clean-up mode after the winter event (which is now being advanced as a 500-year storm event).
Logistics was in a bind even before the couf, and still has not much recovered, so, getting the material, once it's available, will not be swift.
A reactor?
Hmm. Have you formed a notion on how the power is to be transmitted to the tires? Steam turbine seems unlikely. Which leaves electrical motor. High-output electrical motors need some way to dissipate heat while in use.
Water or air cooling are traditional. Both allow for artistic interpretation of color retempering, if a person wanted to.
Mind, a person can make things look how they want, too. Want the reactor to glow in eerie colors--that's cool. Warp plasma is blue in Star Trek, except for when it's red.
