plus the "beta" testers treat it like some kind of fun game. they're like "whoops, almost swerved into traffic. whoops, almost ran into a pedestrian crossing the street."
this article lost me when I saw those numbers. It also treats heat like some kind of magic and not based on thermodynamics. heat is heat, no matter how quickly or slowly it spreads. A big thermal mass will hold heat, but will also take longer to heat in the first place. You're spending the same number of BTUs in the long run.
Yeah I don't get it. People want to buy a home so that they have more space and privacy, including outdoor space. Sure, some condos have roof decks, balconies, or shared yards, but so do rentals.
"Then I have an extension chord to my gas furnace to power the blower and furnace computer."
is anyone else wondering how his home furnace has a regular plug? aren't these things usually hard-wired with a dedicated circuit? you usually need a transfer-panel installed to do this.
Though I don't doubt that Teslas could be engineered to power a home, it doesn't make sense for them to officially support it as a feature. At most, it would power your home for a day before needing to be recharged, so you would need solar panels or a gasoline generator to recharge it. At that point, you would already have a home battery system in the first place, or you would just power your home with the generator directly. Plus, you would need to have transfer panels set up to power things that are hard-wired, like lights, HVAC, pumps, etc. At that point, it doesn't make sense to adapt a system designed to move a car to work with a house.
People get used to treating electronics and computers as black boxes, not concerned with their internal workings since things just tend to work how they should these days. But when you get into high power and batteries, you have to consider chemistry and heat. You can't just plug a 2000W inverter into a battery and assume things will work without any issues down the line.
It's the same reason fast-charge for phones only works with a specific type of cable and connector. Otherwise you could overload the battery or the burn the cable by sending too much current through the wrong cable.
Teslas, despite their hype, are not some kind of revolutionary car. They use the same technology as every other car, though they improve things where they can, such as their motor efficiency. Standard car parts still need to be powered by low voltage, and it wouldn't make sense to make everything proprietary just for the tesla.
Not to mention the main battery would have to constantly recharge the 12v battery, which is probably bad for both batteries. Going from the high-voltage battery to the 12 volt to the inverter sounds really inefficient too. I usually see people using marine batteries as pc backup power, but only using a couple of hundred watts for an inverter.

The batteries mentioned here have 40 or 45 Amp-hours, which I believe would be 480 or 540 Watt-hours (amp hours * 12v), which is not enough to run a 2000W inverter for very long.
Ideally, there would be circuitry to hook up directly to the main battery safely and efficiently.
