How to capture electrons from photoelectric effect?
The biggest problem with a jar full of electrons is that they repel eachother and stick to practically anything.

Could Wimshurst electrostatic generator work in vacuum?
James Wimshurst would have laughed at you and installed a clockwork motor or a magnetic drive. I don't know about Wimshurst generators, but it is common for Van de Graaff generators to be run in pressure chambers. High pressure sulphur hexafluoride is used as an insulator. Unless your battery has something like ten thousand cells in series, that's a horribly inefficient set-up.

Rand Paul Called Fauci a Liar
I'd imagine you are right. But part of the problem is that Trump isn't interested in asking what they like; he's interested in telling them what he likes (or, at least pretends to like) So, he's the one telling them that they can't get a decent job because of immigrants. He's the one telling them they need to have more guns to stop shootings. He's the one telling that that the democrats would poison puppies at perverted orgies ... or whatever. While, in fact, it's the Republicans who seem to get found to be misbehaving. But the media is run by billionaires. Most of the folk voting for Trump do not realise that they don't have much in common with a so called "rich" businessman.

Comparing Corona Virus Success Stories with Abysmal Failures
Fascinating. Can they do the same with other viruses like HIV? Probably a discussion that would warrant another thread.

Origin of COVID (hijack from Rand Paul Called Fauci a Liar)
We hardly need to. The existence of a level 3 in between tells us that that what they were doing was nothing like what you would do if you were working on a bioweapon- as the daft conspiracies suggest. Any "gain of function" stuff would be BSL4. You seem to be missing my point; I'm not saying that the virus didn't "escape" from that lab. I'm saying that it was outside the lab before it went into the lab. And, because it was in the environment, the transfer to people and the growth to a pandemic was pretty much inevitable with or without the lab. It may well be that some of the first humans infected worked in that lab. But that's not the same as saying that they were, in any way, culpable beyond run of the mill ignorance. They were just monumentally unlucky. They were doing what they thought was BLS2 work in a BSL2 lab.

Origin of COVID (hijack from Rand Paul Called Fauci a Liar)
There's no "could" about it. It does indicate substandard precautions. However, my point is that you can't do research on human pathogens without suitable precautions for long- because you die. Anyone involved in the field knows this. So the fact that they were not even wearing gloves shows that they did not think they were working with anything "nasty". So all the "gain of function" conspiracy theories are wrong.

Origin of COVID (hijack from Rand Paul Called Fauci a Liar)
That's pretty close to proof that they were not working on"making" a virus that would affect people. The virus may have escaped from a lab,but it wasn't "engineered" there.

Nor were the people of Germany in 1923- until it happened.

Radiation
We are, pretty much, discussing the spherical cow in a vacuum here. Yes, in practice it wouldn't be perfect, but in principle, it works. Would it radiate? Would it "sort of radiate" because the normal BBR would be blue or red shifted, meaning that it would reflect more or less than would be "expected"?

Radiation
I'm fairly sure I could make a balloon out of conductive rubber and put a motorised pump inside it to move air in and out of a cylinder (also within the balloon). It's absurd, but not unphysical. As long as it stayed spherical, I can't see what polarisation any resulting radiation would have. That's going to make it hard to emit photons.

They probably said that about paper money. That is Plan A.

Cryptocoins: who pays the huge energy?
There will never be more than 21 million bitcoins, and we currently have 18 million of them. So, the "mining" cost will soon stop. the figure of 1123 KW Hr per transactions is... puzzling. domestic electricity prices are of the order of £0.10 per KW Hr. Which implies that each transaction costs something like £100. And that doesn't seem plausible. Is that comparison the equivalent of taking the production cost, which for a Dollar bill is about 5 cents cost and adding it to the cost of every transaction involving that dollar? So, if I buy a book for ten dollars,the transaction cost is 50 cents for the price of preening the dollar bills. The bitcoin only needs to be "minted" once.

How does consciousness arise from within the thalamus?
Before you discuss why or how something happens, you need to establish that it happens. You need to start with " does consciousness arise from within the thalamus?" Because the obvious answer is "no". Do you have a reason to think otherwise?
-
Cryptocoins: who pays the huge energy?
Do you mean... like cash? I'm fairly sure that the blockchain ensures that all crypto-currency deals are exceptionally well documented. Just like all forms of money.

Rand Paul Called Fauci a Liar
Even if you take the claim at face value, it does not make sense. If I give the local university money to research hair restorer, and that university also does research on chemical weapons, am I funding chemical weapons? If they say they spent my money on the weapons, does that mean I funded them, or does it mean they stole my money and misused it? So the interesting question is why is Rand Paul making allegations which do not even make sense? And the other question is why is the OP repeating them?

Ionisation in radioactive decay of atoms
Say you have some uranium (VI) fluoride UF6, and it decays. It spits out a helium nucleus and forms Thorium and helium. But the helium nucleus is shot at at a huge speed. So, according to the conservation of momentum, the Thorium nucleus must be kicked the other way by the recoil. It is usually set moving so fast that most of the fluoride ions simply get left behind. Indeed, most of the outer electrons get left behind too So you get a mess of fluorine, helium, thorium (as ions) and electrons all moving in different directions.

Ionisation in radioactive decay of atoms
Sometimes. https://pubs.acs.org/doi/abs/10.1021/ja01009a040 But usually the energy released tears up the ions involved.

How much pressure do you need to make air go near lightspeed?
I suspect the temperature is so high that atomic nuclei get torn apart rather than fused. It's completely beside the point.

The "Ice Bomb" thermal engine
We don't need to rely on your guesswork. We know that ice sublimes in a vacuum. We also know how the melting point of ice changes with pressure. Raising the pressure reduces the melting point by about 0.01C per atmosphere of pressure.

Electricity using low grade heat
If the equation given here https://www.raeng.org.uk/publications/other/23-wind-turbine is correct, the available power for a 1 metre radius wind turbine in air with a density of 1.2 kg/m^3 travelling at 8 m/s is is 381 Watts. For a 1 metre diameter blade the available power is 95 watts. I can't be bothered to inbox you, but the best help I can offer is "check your maths".

Pressure laws - how hydraulic rams work
In principle, nothing. Three will be limitations due to strengths of materials. The big difference is that the same amount of pumping will only move a big piston by a small distance.
