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.
That cheap green German electricity is currently > 40 cents per kWh.
Last I checked that was with the subsidies (in use most places right now) that buffer the Russia-induced energy crisis. These are running out, partly because the way all the different subsidies were being hidden was unconstitutional.
"Germany risks “deindustrialization” as high energy costs and government inaction on other chronic problems threaten to send new factories and high-paying jobs elsewhere, "
"...a government-funded cap on industrial electricity prices to get the economy through the renewable energy transition."
I guess there may be some subsidies involved.
"...It was mistaken political decisions that primarily developed and influenced these high energy costs. And it can’t now be that German industry, German workers should be stuck with the bill.”
"A 2011 decision to shut down Germany’s remaining nuclear power plants has been questioned amid worries about electricity prices and shortages."
"In the meantime, energy-intensive companies are looking to cope with the price shock."
"“The perception of Germany’s underlying strength may also have contributed to the misguided decisions to exit nuclear energy, ban fracking for natural gas and bet on ample natural gas supplies from Russia,” he said. “Germany is paying the price for its energy policies.”"
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
