Yeah, and absolutely non-recyclable ... from the HUGE TOXIC BATTERIES to

You obviously ignored my mention of Sodium replacing toxic Lithium

This guy, who co-invented the Lithium-Ion battery, is again re-inventing the field.

the ALLOY METALS AND COMPOSITE PLASTICS that these shiny pieces of JUNK
are made from, unlike my Travelall that became a 2 ton cube of reusable
steel.

You also ignored my mention of additive metal metal manufacture (was a topic thread here a year or so back) which is already maturing and routinely used to create medical implants and for aerospace. if you have $500k - $750 you can have one delivered to your business and installed. The metal from these "printers" can deliver parts with up to 90%+ of the grain structure and strength of those machined from "bar stock".

If enough people demand cars made primarily from steel and aluminum they will undoubtedly be provided.

Newer additive plastic printers can fabricate using plastics that are largely recyclable and environmentally friendly.
