Damn, you&#x27;re right. Thanks for pointing that out.<p>Unfortunately, I don&#x27;t seem to be able to edit my earlier post.<p>That changes some of the numbers substantially. Cost of lithium salts at 2015 prices to sustain full Gigafactory production becomes about $USD 340 million&#x2F;year, rather than the $USD 20 million&#x2F;year I initially calculated.<p>The figures about volume of supply, demand and reserves, stand.<p>Sometimes I think it would be worth putting in &quot;dummy parameter&quot; units to stop mistakes like this from happening with dimensionless ratios.<p>Anyway, thanks again for pointing that out.
