Trolley buses did.
Some European electric railways had three-phase power to the locomotives, two phases on the overhead wires and one on the track. The motors used ingenious combinations of stator and rotor pole numbers to give several synchronous speed steps.
(With synchronous traction motors, that might explain why they had a reputation for always being exactly on time.)
Yes. In my ever so well informed opinion. The pyramids have been up and stable longer than ten half lives of any radioactive isotope crated in a reactor
Almost identical, in that a carbon fire in an unenclosed reactor spread nuclear material around. I know ALL about BOTH accidents . I read ALL the literature
And more importantly, I understood it.
Oh dear. That is completely irrelevcant, It doesnt matter what a bomb was designed for, when it goes off accidentally te results are te same
Yup. Of course if the politicians had allowed the rods to be transported to a reprocessing facility there wouldn't have been so many onsite.
Politicos and greens are dangerous people
Read that too, in great detail
Except when they are nuclear power of course. A quick look at who is advising the labour party on energy is enough to make you weep. Greenpeace FoE Ember. Renewable UK
No sign of a single nuclear advocate being allowed within a 50 mile exclusion zone around the Labour Party
-- “it should be clear by now to everyone that activist environmentalism (or environmental activism) is becoming a general ideology about humans, about their freedom, about the relationship between the individual and the state, and about the manipulation of people under the guise of a 'noble' idea. It is not an honest pursuit of 'sustainable development,' a matter of elementary environmental protection, or a search for rational mechanisms designed to achieve a healthy environment. Yet things do occur that make you shake your head and remind yourself that you live neither in Joseph Stalin’s Communist era, nor in the Orwellian utopia of 1984.”

The oldest pyramid was completed around 2650 BC so it been up for about
4,600 years.
Or think you did. The problem in the in the Chernobyl reactors wasn't just a carbon fire - while they did use some graphite moderator elements, and these did catch on fire - but a control failure which lead to a much higher fission rate than the cooling system could cope with, generating enough steam to blown the structure apart.
But neither reactor was designed as a bomb, and only Chernobyl dismantled itself. The Windscale pile just burnt, though it did get very hot, before they finally blocked the air inlets.
Not the same result at all.
But people who imagine themselves to be more expert than they are also pose significant risks, and do need to be outed as pretentious twits.>
And presumably with the same pathetically poor level of comprehension.
Completely wrong The oldest fiisson products are uranium and thorium with half lives in billions of years
Iodine 199 et al are so un radioactive you could bathe in them and be just fine
No you habve. No one except you is in the slightest bit concerned about Inert materials like that. You are more at danger from lead poisoning, which lasts FOREVER

"Canada is all right really, though not for the whole weekend."
What does that mean?
We were invited to a 4th Of July bbq across the street, and the whole yard (which is tiny, in San Franciso) was festooned in Canada flags. Downtight traitorous, in my opinion. Our neighborhood is being infested with Winnipegoos who all seem to work for Tesla.
A giant maple leaf flag was taped to the hillside and was falling down, so I had to climb up and anchor it. All the guys there were programmers, and sometimes you need an engineer.
The burgers were wagu-beef high end, from this place:
It means that to a humorous Edwardian writer of column inches, he had visited Canada and found it insufferably dull..
Greenpeace spoiled its reputation with me when I questioned one of their acolytes about -what I believed was- an inaccuracy in one of their arguments. His reply was that they knew full well that their argument was inaccurate, but that lying was justified if it advanced their cause.
Sorry, but no.

Canadians, and Canadian food, do seem kinda plain. But then, Canada doesn't start many wars.
Places full of sane people don't seem to do much radical electronics either.
No. Unit names are treated like ordinary nouns and are only capitalized where orthographically necessary. The symbols for units named after people are always capitalized.
Are you actually factoring in the extra cost of a EV and
*catastrophic* depreciation into your mileage costs?There we go: FIFY.
Uranium is what you put into reactor - it's not a fission product. There are neutron flying around inside a reactor, and a neutron hitting a uranium nucleus doesn't necessarily cause it to fission but can get capture, which is how some of the U-238 in a reactor gets turned into Pu-239. That isn't a fission product either.
I've not heard that U-235 fission reactors produce thorium. People put Thorium-232 into U-235 nuclear reactors to "breed" thorium-233 which is fissile.
Iodine-129 with it's 15.7 million year half-life, doesn't decay to Xenon-129 all that often, and it only emits a 194KeV electron (beta decay) in the process.
But you don't want to bathe in it. Iodine concentrate in the thyroid, and any 194keV electron can mess up your DNA. Shorter-lived radioactive isotopes of iodine are used to shrink over-active thyroid glands. There's a cancer risk, but not a large one, and hyper-thyroidism is disorder that it pays to treat.
Wrong again.
The Scottish Wanker? Your grasp of reality really is remarkably frail.
Electric vehicles haven't been around for long enough to let you work out reliable depreciation costs, and the "extra cost" of an electric vehicle is mainly due to the fact that they are so far being manufactured in smaller volumes that internal-combustion-engined vehicles.
Like most of Cursitor Doom's "corrections", he's presenting one of his ludicrous misapprehensions as if it were reliable information.
It's 2023 report, and it does mention such thefts in Sydney as well.
Presumably scrap metal dealers have now been visited by the police and reminded that they have to report being offered that kind of "scrap metal". If you can't sell the catalytic converter, there's not a lot of point in stealing it.
He is right and you are wrong. They are primordeal radioactive materials left over from a supernova remnant ejecta when the Earth was formed and have been decaying away each according to their half life ever since.
The oldest *fissionable* materials are uranium (and thorium) which way back was sufficiently U235 rich that groundwater water was able to moderate fission reactions in the Oklo region. Complete with the signature Ru99 isotopic enrichment characteristic of fission products like Tc99 decay.
Clean DU is even used in some of the best radiation shielding (sandwiched with a layer of pre-nuclear age steel on either side).
ITYM *I129* Apart from it having a nasty habit of concentrating in the thyroid gland. The really bad ones from a nuclear accident or detonation are I131 half life 8d and I132 (from Te132) half life 3d.
Pb205 is about the longest loved decay chain product at 1.7e7y (it is a trace impurity that when concentrated by a calutron requires Pb206 isotopic spikes to be marked as radioactive).
It is the ones with a short or moderate half life that are problematic for containment. Sr90 (30y) and Co60(5y) being notable examples.
That's an assertion, not evidence. You should have realised by now that you aren't any kind of reliable witness, and can inf act be relied on to pick the most fatuous lying propaganda around.
<snip>Boast? It was an eventful period, but there wasn't a lot of glory around.
