Wanna bet there's a shitload of effort going into sorting out how to prolong the service life of batteries for EVs? It's only a matter of time before large organizations and nations start looking hard at "eWaste" both from the standpoint of efficient use of capitol, resources and environmental consequences. If recycling was mandated (by law), how many vendors would rethink their approach to product design? (Do we really need to assume the cost of retrieving that 75 inch TV from the customer just so we can sell him ANOTHER? Is there a better way to pitch improvements in *features* instead of pels or screen size?) Here, you have to PAY (typ $25) for someone to take ownership of your CRT-based devices. I see Gaylords full of LCD monitors discarded each week. And, a 20 ft roll-off of "flat screen TVs" monthly. Most businesses discard EVERY workstation in their fleet on a 2-3 yr basis. The software update cycle coerces hardware developers to design for a similarly (artificially) limited lifecycle. [Most people are clueless at the volume of eWaste that their communities generate, regularly.]
