Hi Lee and All,Remember last time they tried this their market crashed as everyone designed REEs out and China ended up with lower prices, lower demand.That wasn't the biggest problem though as it signaled China wasn't a reliable supplier of anything starting the mass exodus of companies pulling their supply chains out of China.In the last 2 yrs that leaving has turned to a flood as Xi leads China in Mao thought hurting their big companies and already lost about $2T in stock value just in them.China's economy is crashing because of this, Xi's policies as everyone that can leaves. Hopefully CATL's tech makes it out.As for REEs the Phosphate tailing mountains for Florida, the highest points now, are filled with REEs and other metals, etc that just need refining, to last us several decades.And E motors don't really need REEs.The real effect will be in WTs if any.Jerry Dycus.

Big corporations tend to favor monoculture solutions (*one* way to do everything). Economies of scale, marketing pressures, monopolies, and good old "we've always done it this way" tend to push everyone into using *one* technology, even when there are viable alternatives. This is, after all, why we're still stuck on ICEs despite the alternatives. But what happens when over-use of that one solution leads to shortages in a key component? History shows that corporations tend to force new supplies to be exploited (more mining, more environmental destruction, more revolutions, even more *war*). The more rational option is to use something else, or find a better alternative. But this only seems to be tried after the brute-force methods fail. To paraphrase Winston Churchill, "You can always count on corporations to do the right thing, after they have exhausted every other possibility." There are plenty of other types of motors that don't need magnets. EVs have been using induction and series motors successfully for decades. There may be some minor performance reductions (slightly bigger, heavier, or a bit less efficient). But we rarely allow the "perfect" to drive out the "good enough". For example, silver is a better conductor, but we use copper instead because it's cheaper and more available. Magnets can also be made without rare earths. Material science is advancing at a rapid pace, so it is likely that alternatives will be found that are just as good, perhaps even better. Recycling can of course provide another source of supply. Magnets don't "evaporate"; instead of being dumped in a landfill, they could be recovered and re-used. Note that all these arguments apply as well to other "scarce" materials, like lithium for batteries. Lee Hart -- "All children are born engineers. Watch them at play.
