When fusion becomes our main power source, much sea water will need to be processed to extract the Deuterium. Lithium could be a byproduct of that extraction.

However if this technology is as good as they say it is, then one should be able to get the same range as the Tesla, with only 1/10 of the batteries, i.e. only $5000 worth. That would extend the Lithium supply, and also make the vehicle much more affordable. In fact due to the reduction in weight, the range would probably be somewhat greater. I suspect the nanowires have an additional advantage, namely that the increased surface area should significantly decrease charge time. [snip] Regards, Robin van Spaandonk The shrub is a plant.
