I just went to a conference in Hawaii, which is usually a very popular, but half the poster boards were bare. I saw multiple recorded talks because the speakers were denied entry visas, including one of the opening keynote speakers.

And the fuse for the circuit absolutely should not be the limiter, the RCCB should trip WAY before the main fuse.
While that certainly SHOULD be the case, in the US at least while RCCBs (we call them GFCIs) are generally required in wet areas and perhaps for new construction, in most older houses the majority of circuits don’t have any sort of ground fault protection other than the fuse/breaker. In my current house we have them on only two outlets - one in a bathroom and one in the kitchen.
In most household shocks, you touch a conductor, and you are the resistor to ground. Your resistance is independent of the drive voltage, so if you touch a 110V wire, the current will be half of what you get with a 220V wire. So the voltage determines the current, and thus the lethality.
There’s lots of other factors that go into the effective resistance like the amount of moisture on your skin, what shoes you’re wearing, and what the floor is made of, etc, but in all cases twice as much voltage will cause twice as much current. You are by far the highest resistance element in the circuit, so your resistance will completely determine the current - most household circuits are capable of supplying 10-15A continuously, so your resistance is the current limiter.
It’s a bad idea either to go touching live wires either way, but the rule of thumb I heard was was that a 110V shock usually won’t kill you and 220V shock usually will.

A road built and maintained by taxpayers is much cheaper (to a shipping company) than building, maintaining, and operating a railway. Making taxpayers responsible for the infrastructure you use is one way to make your business much more profitable.
Yes, but that’s all subsidized by taxpayers, so it’s more expensive overall but cheaper for YOU.
What it will mean in practice is that every objective fact has to be balanced with a right wing talking point.
Gosh Tim. How is that million dollar personal contribution directly into Trump’s pocket to Trump’s inauguration fund working out for you?
Trump’s plan for ending the genocide is to let Netanyahu complete it.
“He blew the whistle on a multibillion dollar company - obviously he knew they’d kill him! Suicide.”
I’m sure that’s a much more effective than trying to build up US companies to make solar panels.
“I’ll believe corporations are people when Texas executes one.”
No worries. Still interesting!
Yeah, I think you’re right.
Ok. Have a nice day.
I have no idea what you are trying to say. Batteries have an environmental impact, but so does fracking for natural gas. You have the impact up front making a battery, but charging it with renewables does not have continued environmental impact. But if you use gas, you’re going to have to use an awful lot of it over that time period to offset the clean power you’re able to use when you have a battery. And that gas has a very high environmental impact, continually, over that entire time period.
I didn’t say batteries have NO impact, but they have less impact than continually mining and burning fossil fuels.
You make the batteries once, and the pollution due to production is spread over the 10-15 year lifetime of the battery. During that time gigawatt hours of clean power sloshes in and out of them. This in contrast to having to produce enough gas to make all of those gigawatt hours once, then throw the gas away as co2 and get more, along with the attendant pollution.
You’d think they of all people would understand the concept of data leakage.
34% is 155% of 22%, so an even bigger increase!
Of course, if they’re in the army, can’t they be executed for treason and the like?
