I have no idea whether anyone will buy Tesla. If Jason or someone he likes a lot has invested in Tesla, it could be a teaser he put out to try to get someone else interested (Google). Or it could be his sincere opinion. I'm going to go off topic from the will-they-be-bought-or-not question because that seems a bit beyond conclusive at the moment. Even for a random internet commenter like me. Instead I'm interested in the author's dismissive attitude toward the household battery idea. The author tries to refute Jason. This paragraph is where he lost me: > And for what purpose? So I can disconnect from the electric grid for a week, and then reconnect again when the battery has run out? Or to power it with expensive solar panels? I don’t think so. Just because you can come up with a question, and you can't yourself come up with an intelligent answer to the question, doesn't mean that the question has no good answer. In this case, with just a few moment's thinking I can easily come up with a better answer to "for what purpose": The answer is, this leads to all sorts of savings and efficiencies, namely: - A good household battery makes the grid more flexible, and gives the owners of batteries access to cheaper off-peak power. - The grid can be less stressed, meaning it doesn't have to be overbuilt as much. Some of the current maintenance costs can be eliminated or allocated to more constructive uses. - Loads become more balanced, eliminating the cause of some brownouts and blackouts. - Centralized solar becomes more practical. - Decentralized solar becomes more practical and useful 24/7. (And by the way it is now competitive with grid rates, and getting cheaper every year). - Other widely variable energy sources (such as wind) become more practical. - New businesses facilitating alternative energies will become viable. Including possibly some businesses represented today only by twinkles in Elon's eyes. - Over time, not only do battery owners, but other consumers as well, may end up paying less for power than they would have otherwise, because of the efficiencies introduced to the system. There are so many benefits, the kicker being the direct cost savings to the consumer which will give them a reason to invest in these things. And while talking about cost to consumer, I consider it likely there will be subsidies as well, possibly government, possibly corporate, possibly both, because the other dividends (see above list) are so compelling.
