Looks like Tesla is investing in a domestic battery cell factory. Its projected output in 2020 will be approximately equal to the amount of cells output across the entire industry last year. They estimate a 30% decrease in cost/kWhr, which is pretty cool. Oh and they're building a ton of solar panels and turbines to help power it. Pretty cool if you ask me. It makes sense to me - if Tesla continues to grow, why pay the middleman for one of the most essential items in their cars?
