UK availability?
Does the sun shine in the UK? Cheer up, one day it will...

Why does there need to be "the best" preschool. Can't we have a society with standards? A society that gives a damn about iniquity?
I think you mean inequality...iniquity is sin...which society doesn't care much about either lol

They haven't delivered a Model 3 yet.
That's not the point. Sales from their previous, more expensive models allowed them to ramp up production capacity for the Model 3.

I agree with the sentiment, but I have to correct your idea that global warming is a species-ending problem. The worst-case scenario of global warming (which might be inevitable given the current CO2 levels) is a 216 foot rise in sea level [1]. This will cause mass migration and be extremely expensive and unpleasant for society as a whole, but poses little threat of ending humanity. NASA's JPL did a great lecture a f…
You are looking at a very small fraction of the problem. Yes higher water is not an extinction level event. But with increased CO2 there's also increasing acidification. So the plankton dies, coral dies, mollusks die (their shells erode). The food web at sea dies.... as does the food for a decent fraction of the planet. Acid rain causes more damage, food production becomes tougher... especially on the decreasing numb…

Where I live (Northeast), pretty much the only time where an extended power outage is a serious problem is in the winter. And that's because of losing heat. A Powerwall-like "UPS" that could handle some critical systems (basically my furnace) automatically is interesting. But any solar panels are likely to be under snow and ice. Pretty much the only thing that's really a problem for me in a power outage is losing hea…
How much heat would a powerwall even create? I suspect electric heat would drain those suckers pretty fast. Why doesn't the north east have gas heating?
You're right that, if you have electrical heat, a Powerwall would be pretty useless.

I didn't mention price. It could have been a high-priced, low performance, average-looking, electric, family sedan, and it would have been more effective at transporting people (more seats in a sedan) plus better for the environment. The point is that the appearance and performance sold for personal and emotional reasons.
That only works if enough people want expensive, low performance, average-looking, electric family sedans.

>If I put that same $40,000 in an index fund that got the stock market's historical 7% average, and waited 30 years, I'd have $308,000. Are you doing the math all in present dollars? Because the return is 7% after inflation but >10% before. So you'd have >500.000 in 2047 dollars. In this case it's important to do that adjustment because you're doing an investment upfront for payoffs over 30 years so the value of mone…
The case can be made even stronger if the consumer's efficiency gap is taken into account. For example from "Market failures and barriers as a basis for clean energy policies by Marilyn A. Brown" we read: "Meier and Whittier (1983) studied a case in which consumers were given a choice in stores throughout the United States of two refrigerators that were identical in all respects except two: energy efficiency and pric…
I think if this is the case, they certainly don't want to hint at it incase they lose consumers who will sit back and wait for the cheaper option they ironically wouldn't arrive.
People are thinking way too much about how much this saves them at a personal level. I think people should instead be thinking about how we can save the existence of the entire species, and all other higher order forms of life on earth, rather than focusing on their individual tax breaks, savings, or other trivial concerns. Yes, your cash flow is rendered quite trivial if life on Earth ends. Invest in the Life Econom…
Tesla roof isn't going to save the species and life isn't going to end. I expect this type of comment on reddit, not on hacker news. > Invest in the Life Economy, and turn your back on the Death Economy. Are you serious? This doesn't pass the smell test. This sounds like something from a PR firm hired by Tesla to "evangelize" on social media.

If the economics don't work, then you can wish you are saving the planet all you want, but it ain't gonna happen. Elon Musk understands this very well -- he always points out that solving the global warming problem will only work if the solution is economical.
