At a Beverly Hills mansion, where an electric truck is your only source of power

 

Quote

As sunset fell across the Hollywood Hills, the chief engineer from General Motors flipped a breaker and disconnected the five-bedroom home from the grid. The lights went out, and less than 20 seconds later, GM’s home system powered it back up, pulling just 5kW or less from the fully charged Chevy Silverado EV parked in the garage.  

 

Quote

This was no temporary solution, either. GM executives promised that the mansion could run for three to four days at that level of consumption before fully depleting the battery. When I left at around 9:30PM, the charge on the Silverado EV had only dropped by 1 percent.

So what? It has long been stated that the batteries from an EV that had lost too much range, could still be used for home power outage backup. So naturally a fully functional one would work. But why tie down your EV to do it when you can purchase a MUCH cheaper home backup?

Seems pretty neat to me.

If you had a disaster that cut power to your home and you had a EV sat in the garage that could give you power for several days that seems a good deal to me.

I have a 5 Kw battery hooked up to my solar panel and it would not even power the home for a day never mind a few days an it was not exactly cheap either.  🤔

My neighbor did the same thing with his diesel powered pick-up truck and an inverter. It didn't power everything, but it kept his refrigerator running, plus a few lights during a three day outage... I suspect an inverter is a lot less expensive than the cost difference between his truck and an equivalent EV.

 

I suspect he had some power to spare, because he offered to let me plug in my refrigerator.

Apples and Oranges. A 5Kwh battery with inverter, is less than $1,000 U.S. That truck cost $50,000 or more. If you can afford that truck, you can also afford a backup system for your home that also allows you to use the truck for other things during an emergency.

Energy is finite and everything has a cost. Lithium batteries don't last forever, and using electric car battery to power a home will shorten the amount of driving lifetime.

Fuel for a vehicle is expensive and dirty, so only ok for emergencies.

A bunch of solar panels with battery storage is currently the most efficient and cost-effective particularly in an area with a decent amount of sunshine.

From the article I posted about.

Before the event, GM Energy installed a bidirectional charger, which the company calls the GM Energy PowerShift Charger, as well as its own V2H Enablement kit, which includes a power inverter, a home hub that includes a computer system that manages the loads through the house, and a backup battery. The full kit retails for $12,699, but buyers can opt for the individual components at the same price.

These backup power systems essentially provide microgrids for communities and homeowners looking to insulate themselves from blackouts due to extreme weather resulting from climate change.

Probably more than what you wanted to know about audio file formats 🙂

Excellent video! Every music listener should watch. I use almost exclusively FLAC and OggVorbis for music files, with a few mp3s but they are less efficient and don't sound as good. I just finished going through my music collection and deleting dozens of low-quality mp3s because they sound bad.

ExplainingComputers has a great presentation style, all facts and no BS. He's been making videos for 16 years. And now I scrolled through his channel and have another 8 videos to watch. 🙄😁

Every once in a while he throws in a joke.
