That will be great with lithium-ion batteries for areas with year-round temperatures between 14 and 86, Fahrenheit or with needed additional equipment. Chinese battery charging, heating and cooling equipment investments should do very well.

True for now. I would not want to be driving a Tesla in the Rockies during the winter. Likely that’s why the Tesla plant is in Balmy California. Still, there is a huge section of the USA that has year round temperatures between 14 & 86 degrees. When a decent percentage of their driving public switches to electric cars—the price of gasoline all over the country — including the cold places goes down.
I don’t follow closely the battery/solar/electric car companies so I wouldn’t be comfortable investing in them. Still anyone can see from a distance that a lot of these companies stock prices are rising including Tesla. Tesla for its part just signed an agreement with Panasonic a Japanese company to get financing from them for 200 million dollars for the construction of a new battery plant which promises to bring down the cost of Teslas. The plant’s total costs are said to be in the 5 billion dollar range. I don’t know where the rest of Tesla’s financing is going to come from.
