Looks a bit "Rube Goldberg-ish" to me, but creative for sure.

Everyone always forgets about the lithium and how toxic it is to mine, work with in manufacturing and the fact it can't be reused so it's a rolling barrel of toxic waste when it's done.
An electric cars manufacturing carbon footprint exceeds that of a pzev gasoline car in it's entire expected lifetime. And a majority of the power consumed by these wonder cars is generated from fossil fuels or coal so it keeps making the carbon footprint bigger. They aren't environmentally beneficial. It's just a convenient way for people to think they are. (IMG:style_emoticons/default/headbang.gif) |

Because Lithium historically has been pricey, battery designs continued to evolve using even less Lithium while still performing well. Lithium prices are down recently in part, due to Lithium conservation and the reduction in demand for Chinese EV's. Why is China demand down? In part, because the Chinese government is reducing its subsidy of EV's! However, there are other expensive metals used in batteries that aren't well known, or widely discussed. Namely Cobalt, Nickel, etc. These commodities markets are very volatile even under the relatively small market share that EV's have. What happens as EV's come up to scale is anybody's guess. https://www.greencarreports.com/news/112477...other-materials The EV situation is complex indeed. |
