Yeah, and absolutely non-recyclable ... from the HUGE TOXIC BATTERIES to You obviously ignored my mention of Sodium replacing toxic Lithium [2]https://www.nytimes.com/2017/04/07/opinion/sunday/to-be-a-genius-thi nk-like-a-94-year-old.html 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. Rr Have you ever cracked a sodium filled exhaust valve from a modern automobile open and dropped it in a bucket of water? Do it [3]. That way we'll most likely never have to see your posts on this list ever again. Your simplistic rose-colored-glasses worldview should be wiped from the slate along with you. Just the notion that filling landfills or hazmat disposal sites full of sodium batteries instead of lithium is somehow 'better' indicates a certain STUPIDITY only seen in consumer capitalist societies with half-educated morons desperate to keep accumulating shiny shit. Further, where the FUCK are you going to get the power so "Newer additive plastic printers can fabricate using plastics that are largely recyclable and environmentally friendly."? Coal. Natural Gas (parboil instead of suffocate) Fuck off and die, and hopefully your phantasm of a technological panacea will die with you. Not likely though ... there's a mental midget who will never be able to 'connect-the-dots' born every minute.
