RE: Tesla’s battery problem1 Nov 2020 06:25
Macanman and VauxhallViva - coincidentally I watched this Real Engineering video on youtube earlier this morning, then I remember the comments made here previously.
Whilst RE videos are slickly put together I'm not sure they really understand everything that they are talking about - for example they described mineral 'reserves' as 'being held back to keep the commodity value up' - this is a complete misunderstanding of the concept of a mineral reserve, and makes it sound like the stuff is just sitting in a warehouse somewhere just waiting to have a shipping label just stuck on the side of the box. It is nothing of the sort, it is still stuff in the ground, which 1) may not be as easy to get out as you think and 2) when it is dug up can only be processed at a specific local site with the existing limits of processing capacity and 3) includes many reserves that may well be uneconomic to mine at current commodity prices.
It does not surprise me that they don't know what is happening with flow batteries yet - their heads are filled with all the fascinating complexity of the Lithium-ion battery technology and marketing propaganda - Lithium, Nickel, Cobalt, Graphite, Manganese, Tabbed, Tabless, Tesla, Nikola (watch RE's breathless video on them here - https://www.youtube.com/watch?v=7ynupYBLlyA ) , 100 Million, 100 Billion, 100 Trillion, Yada, Yada.
Now imagine a grid battery that uses only a single metal element.
An element that is more abundant than Lithium, Cobalt, Nickel, Chrome or Copper.
Where extractable resources exist all across the world, including the good 'ol US of A
Where the energy storage capacity can be increased at sublinear cost (double the energy storage is not double the price)
Which is ideal for building massive SAFE batteries that cannot burn.
Which has already been used to build the world's largest battery, in the centre of a city.
