That's about $0.16/KWh which is the average electricity rate across the whole US and significantly less than the price in the Northeast. I haven't dug into whether that's apples to apples - whether the country average is (generation + delivery) or just generation, while the rate bing paid to the plant is presumably just generation. But either way just the cost of electricity generation ignoring delivery on my bill is quite a bit higher than that.
Re:DeskHop – Fast Desktop Switching on Wednesday December 27, 2023 @10:28AM (#38782887)
I share two monitors and audio equipment between a desktop and a windows laptop (dell XPS) using a "dumb kvm" that wrangles a few USB outputs and two DisplayPort inputs. the laptop only has USB-C output so it connects to a fancy thunderbolt dock borrowed from a friend which then goes to the KVM. I have a third monitor only connected to the desktop with a laptop stand in front of it for a third screen

It takes a couple seconds to switch but otherwise works flawlessly unlike my previous solution of shitty dongles, switching dual input monitors, and moving a usb hub input cable between machines. I also considered rebuilding the desktop to have a thunderbolt output and buying a thunderbolt switching KVM but I couldnt make it work

I think scooters are about where it stops working well at a consumer level.

Battery swapping exists in the forklift industry but it is complicated and dangerous. Forklift batteries are about a thousand pounds (less than car batteries) and often open cell lead acid (which has additional challenges that lithium doesn't like spills, watering, and gas discharge). In the type of forklifts I occasionally see, the batteries sit on rollers with a side access door and lockout. the tunnel the battery lives in is a little wider than the battery, has a gate that must be reinstalled, and the battery slides around a little during operation. Battery is connected to the system with a flexible connector.

Despite the electric forklift battery swapping industry being a lot smaller than the car charging industry it seems to be a reasonably dangerous affair. there are significant OSHA regulations, and a nonzero number of yearly injuries.

If you were going to operate a car battery swapping lot, you would probably need: powered battery swapping trucks manned by professional operators, a very flat well maintained driving surface, an indoor charging room, a standardized car battery placement, access system, tie down system, and battery size. you would need to worry about things getting caught in the battery doors, the battery - car cable getting severed, making sure you were perfectly lined up with the access door, and about doing some sort of tie down routine.

It's doable but it would be a LOT of work to get right. Batteries aren't as fungible as tanks of gas so you'd probably only use such a system for corporate vehicle fleets or special lease pools.

Second link isn't great and is selling batteries but it seems to cite useful figures
