Assuming V2G means Vehicle to Ground, this is something I would like to see for the following use-case.
I would like to use my car battery as a temporary home battery in the inevitable case of a grid outage. This opens the option to bring energy home from another location. Reduce or eliminates the need for a battery in a grid-tied house.
Am I crazy?
Edit: Granted that doesn't mean the energy company can use my car's battery at it's whim. I think compensation would be required and would actually make a lot of sense. It isn't like the electric company could build out a battery system for cheaper. It would need to be a higher compensation than to PV though. Batteries are more expensive and should be compensated as such.
V2G = vehicle to grid. It’s quite possible for this to operate as a backup battery, but like a Powerwall it requires extra “gateway” hardware to ensure that your house is isolated from the grid when the battery is discharging.
V2L (vehicle to load) is a simpler form that lets you power 115/230V appliances directly from the vehicle. Quite a few EVs (Hyundai, Ford, etc) already support V2L.
There's two ways to power your house off your car battery. You could have your car act as a mobile electrical outlet that you can run extension cords off of to plug things into, or you could have it tie in directly with the wiring of the house so all your electrical outlets work.
The former is pretty straightforward. The latter would need a lot of electrical upgrades to the house. (I'd expect you'd need to do about the same thing that people do when they get solar, which is to replace the meter with something that can measure power flows in both directions, and is smart enough to disconnect the solar panels from upstream power when the power goes out, so you don't electrocute people trying to fix the power lines. If you don't have a local battery, that means basically turning the solar system off in a power failure.)
If you aren't planning on selling storage capacity to your local utility, maybe all you really need is an automatic shutoff switch to disconnect your house from the grid when the power goes out.
Either way you'd need some sort of power inverter to convert DC to AC. That could be built into the car, or it could be attached to the house.

Question is "how long?" and "how much?"
Lets take a 100 kWh battery which matches a Tesla Model S battery option and is a nice number for doing conversions from.
> The recent figures, as of 2021, show that the average annual electricity consumption for a U.S. residential utility customer is 10,632 kilowatthours (kWh). If you divide that by 12 months, the average monthly electricity consumption is 886 kWh per month. What about in a single day? That would be 10,715 KWh divided by 365, or 29 kWh. Then the average daily electricity consumption is 29 kWh.
So, hypothetically, 100 kWh would give you 3 and almost 4 days. This can be improved by unplugging things that consume more power. The other part with this is a "once that 100 kWh is drained, you're stuck stuck."
You're going to still need something between the mains power and the circuit breaker box. I'm also going to note I don't know what rate it can discharge.
And from that, look at the "this is what we want" and the question of "generator or battery" becomes interesting.
Then consider also, you can get a 10,000 watt generator (that does a cutover in event of a power outage in 7 seconds) for about $3000 which can provide 10 kW at 40 amps.
Anyone expecting regular 4+ day outages is already going to have a generator. What people want is for the car which is already plugged into their house to kick in when the power goes out for an hour or two.
At an hour or two, that's ballpark 3kWh of power you'd need. There are battery backup solutions in this range that are $3k to $6k (that are frankly quite interesting.
Those have the instant on design so that if the power is lost to the house you have a few seconds and its back up and running.
You may not be at home during the power outage. This could impact things such as aquarium support, home security, or cold food storage.
You may need additional equipment or an upgrade to existing equipment to do the power outage cut over. To do this (and not just support an outlet from the vehicle), it is necessary to remove the house from the grid for the duration - suddenly changing phases can damage equipment (e.g. when the power comes back on). Additionally, if you were still connected to the grid, it would mean that your batteries are trying to support the portion of the entire grid (which it will fail badly at).
This also depends on the equipment that you currently have. Not everyone has a battery backup Tesla power wall. If you are plugging the car into 120v or 240v outlets, that doesn't have the circuitry to support isolation of the house from the grid after a power outage and the wiring for the 120v or 240v outlet isn't heavy enough to support the current draw for the rest of the house even if it was isolated.

That's not crazy, it's actually a publicized optional feature on the F-150 Lightning, and the F-150 hybrid has an optional 240V 30A output that can be used as a home backup as well (although that'd be a bit more manual).
Depends on your appliances. 30A @ 240V is 7.2 kW; which is plenty if you don't have AC or electric heating or cooling. If you do have those, you'll at least need to be sure not to run any two of those at once, if you can run them at all; you need to be careful with things like dryers, heaters, heat pumps, air conditioner, oven, stove, water heaters (especially tankless, but check your amps on an electric storage water heater too). Well pumps can be big loads too; mine is rated at 30A by itself, but many people have smaller pumps or utility water.
FWIW, the F-150 Lightning car to home option only goes up to 40A, which isn't that much more.
Maybe, I switched myself and family to bitwarden. Once I did the transition I realized how easy it was. I spent maybe 5-10 minutes to help my mom transition.
tldr:
1) Create bitwarden account
2) Export file in Lastpass
3) Import file in bitwarden
it's not that easy since not all the information (e.g., additional fields for some sites) gets exported, so you still need to do manual check to avoid losing access (and of course you don't remember which sites you had those fields set up). So it's still risky to delete LP after the switch
Dude! This exactly. Think about having to explain that to NASA. Ahh sorry I can't fix this major SEC issue because our developers can't do a release atm. It went over as well as you'd think. I had to pull out our actual contract to be like "Well... we actually have like 8 days to fix this criticality of SEC so..." Then prayed to Al Gore and Linus Torvalds that what ever this dependency was would be resolved before I got my ass handed to me.
Btw if you do this often look into the Auto Reader View addon. Then the common places you visit and can use reader view will be viewed in reader view immediately. The escape hatch works to which is nice. https://addons.mozilla.org/en-US/firefox/addon/auto-reader-v...
Safari has this built in and it's magnificent. I can't remember the last time I had to peer through a 20px high peephole at content on the Guardian website.
Agree, I'm wondering when they start going door to door removing peoples "right" to be on the internet due to their beliefs. It seems the silent stick has finally come to the US and likely the whole world by extension/association.
That's is interesting. Makes me wonder what will happen now that this is happening to a much broader group of people. The migrations and reactions will be larger than we have seen in the past. It feels almost like we are seeing the slow creation of internet slums. An expansion to the legitimate dark web?
After I gave up on the idea of preserving an existing Linux install (that used a file system, namely, btrfs, that NixOS's installer does not currently handle), and just allowed NixOS's installer to nuke my block device (i.e., my "hard drive"), it was easy for me to set up and configure my NixOS install to my liking -- and I know very little about Nix and NixOS although I consider it worth learning, which probably greatly affected my attitude, which has historically had a large effect on whether I succeed or fail at sys-admin-y tasks.
Where the learning curve gets very steep is when I tried to build something from source code! I would've liked to have built Emacs 24.4 from source, because that is the version against which my Emacs Lisp code is tested, but I gave up. (I'm using Emacs 26 instead and spending time adapting my Lisp code -- something I probably never would've needed to do if I could've built 24.4 because I am moving off of Emacs.)
If you're using x86_64, there are tens of thousands of packages with pre-built binary packages, so it might be you never have to build something from source to get the desktop environment you want.
As long as what you want to do is already in nixpks it's extremely easy, once you stray from that you need to start learning how all of it works, it's not the best in terms of documentation & straight forward concepts, but I've been running it at my main desktop for 6 months now.
Sometimes it shines ex:
I messed up my x11 config as well as drivers and just booted into the previous generation like it was no big deal
I needed to install a version of electrum that was only available on a specific git commit. I just specified the commit and booted into a shell with it
Sometimes it sucks:
Learning to package arrive 3rd party software can sometimes be really complicated and it might be the only way forward.
Lots of steam doesn't work out of the box compared to Ubuntu.
Second this. It's mostly been a pleasure, but Steam is a mess. And I just gave up on Android development on NixOS; I used a Ubuntu VM for that.
But starting off with a new computer, copying over a config file from one of your existing files, building...and ending up with _exactly the same system_, including all those tweaks to _this_ file and _that_ config, and the cronjobs you've set up over time, and all your different rc files, is magical.
Steam works fine for me. Also, the "NVidia prime" stuff from https://nixos.wiki/wiki/Nvidia works out of the box since 20.09. (Though i will be happy when Dell finally sells AMD graphics instead.)
Also I've made android packages (albiet ones that don't use much Java) using the Nixpkgs repackaging of the Android SDK.
I run Nix on my workstation and on my laptop, and have been doing so for a couple of years.
Most of the issues I ran into were just nix being different from other distros I use, so I did have to relearn a few things.
The remainder of the issues are the sorts of things one runs into with a non-rolling release distro. For example, a program I use got a feature I want last September. I'm going to have to wait until March for it to hit stable, since NixOS is on a September/March biannual release schedule.
The good news is that I am running the latest version of that package just fine now; Nix lets you install "overlays" of the package system into your home directory (or globally), and I just copied the package definition into the overlay, updated the URL and SHA256 sum to point to the new version and it "just worked."
Downside of course is when I upgrade to NixOS 21.03 (the march release), I'll have to remember to remove my overlay version of the package, or I'll be frozen on that version. There may be some fancy way to work around this which I haven't discovered, but since I have like 1 or 2 packages in that state at any time, I just manually do it when I upgrade.
I started using it as desktop os two weeks ago. I've been quite happy with it. Fast and snappy gnome desktop. Took half a day to install and get comfortable
Then anouther half day to get comfortable with home-manager to configure my user settings
