Bingo! and overall it's hard not to feel like this is a historic night, possibly Tesla's biggest game changing development to date! electric cars/the auto industry, yeah big potential there over the long run, but given the price and sophistication of what was unveiled tonight with energy storage and the potential scale of applications, the business potential could easily dwarf anything Tesla will ever do with cars and it could happen very rapidly! the presentation tonight missed one of the main things that batteries have to offer the grid. electricity production is made to match consumption but capacity to generate or baseload is essentially constant, meaning the amount of water going through a dam or steam being released from a power plant is remarkably constant because turning up and down the flow is not easy, instead, water/steam bypass turbines during off peak, resulting in tremendous waste. if a utility was able to run all the steam through the turbine, for the same cost in energy consumption, producing constant peak generation potential, now able to store the excess in batteries overnight, the potential in generation capacity is exponential, making it possible to meet growing energy demands without new power plants (renewables aside for the moment) and dramatically cutting the cost per kW of electricity production. this should lead to a glut of electricity in the market. the cost of driving electric among a whole lot of other things, would likely plummet. how many folks go off grid is not the big fish here in the short term, it's how it's suddenly cost effective to capture off peak excess waste!
If the market gets this, the stock price could launch like a space X rocket tomorrow or soon thereafter!
