Hi fdr, been a bit AWOL these last few days so apologies for not replying before. Thanks for the summary on the 2 guys ......................... don't think I'd disagree with anything you say there tho I'm no expert in such analyses. I tend to simplify it down (for my own benefit) to people being in one of 3 states "1 - Mad", "2 - Barking Mad" and "3 - A complete Fruit-loop". :8 On the "H 'n 'H Scale" the 2 guys you mention are .............. - erm, so as not upset the Mods I'll simply say 1 is "1" gusting "2" and the other is "3+"!!!!!!!! :ok:

Anyway, re this:- "Quote: Originally Posted by Hot 'n' High Sadly, the same thoughts were voiced re a certain perpetrator of a SMO............. https://www.pprune.org/images/smilies/yeees.gif", I think you misunderstood me. I was responding to a prior Post which suggested that "general ill-health" might mean DT does not see his term out in the WH. I was just making the observation that, at the start of the infamous "SMO", the same hopes re Vlad were aired as a being a swift solution to the Ukraine War. Of course, we all know where we are there..........

Hope that clears that up! Cheers, H 'n' H

Someone plug a US appliance into British mains power?

”What’s that smell?…… Is that smoke? …..Is that flame!?
”Fire! Fire! Fire! Help! Help! Help!”

Had a couple of dipsticks for making Tea in the middle of the night - discovered that a USA one would boil a cup of water in Kinshasa about 10 times faster than a Brit one…worked well until it went bang.

Around 50 years ago, I bought a 'Realistic 1000 Watt Foreign Travel Voltage Converter (273-1402A)' from RadioShack, to run a 1000W electric wok which I'd bought in the BX at Offutt. It works OK....ish, but I'm not convinced that the output really is 110v as it takes quite a while for the wok to heat up. I also tried it with a 110v coffee percolator - again it worked, but took an age for the coffee to be ready!

In most of the world electrical goods are built as 110/220V - 50/60Hz as standard.

It was only when I lived in the California and bought a reasonably expensive HiFi I noted the power block was just marked as 110V and phoned the service centre who sent me a 110/22V block free of charge.

They explained that with most of the world it was easier to just supply a dual voltage un it across markets, but the USA was a large enough market that the few cents difference added up and made it worthwhile producing a US specific supply.

You can buy cheap 220-110V voltage converters of course, but that doesn't get around the 50/60Hz problem.

Many years ago while 'travelling' with the RAF I became the proud owner of a dual voltage HF Radio - The Sony ICF 7600D. The only snag was that there was a switch on the adaptor where you had to select the input voltage. I had just spent some time in USA so the switch was in the 110V position. Next stop was Germany and I forgot to select 220V on the switch. It wasn't a spectacular overvoltage but neither the adaptor nor the radio never worked again! I tried the radio on batteries but no joy.

6 decimal places precision, but we don't know the accuracy. We probably care more about the latter.

6 decimal places is just a number chosen by whoever does the conversion - it could be 12 places but as boaclhryul states it's meaningless - and that's without getting into issues of geodesy (my life isn't long enough)

One of the most aggravating things in the data acquisition world is trying to convince requestors that you can't make a 5% measurement more accurate by sampling it with 14-bit resolution. (Yes, that actually happened.)

When my father first moved to Menorca, we found that some parts of the apartment were still on the old 127v system and the rest was on 230v. That was fun....NOT!

A friend of ours was so concerned about a stable power supply to his top end HiFi syatem that he bought a couple of autotransformers. These sampled the input voltage and a motorised device moved the secondary windings around the toroidal primary windings so that the output would be a constant 230v - at least, I think that's how it worked. But the Menorcan power grid had been improved by then and the input voltage was always rock steady anyway.

Huge thread drift

Week 8 Recap.

Don’t most power blocks put out DC? In which case the frequency of the input shouldn’t matter that much. I would think 110v at 50Hz would work

What say we accept a short circuit end to this jibber jabber about AC electrics and get back to the topic of the Thread.

Off topic posts are not electrifying reading.

Oo look, a squirrel!

Its all gone awfully quiet on Iran. Is this the new normal?

Trump may be cueing in that decapitation works better when you're ready to put boots on the ground and put your own folks in charge:pEast Asia might be inclined to allow tankers to etch a sketch through their various territorial waters so that they can get oil delivered;)​​​​​​​

Correct, it simply gives you better resolution.

Pakistan and India are missing a trick here - they could do a roaring trade if they took in Iranian oil at one of their storage sites then sold it on to other nations...

The logistics of doing that is pretty lousy. The Islamabad–Tehran–Istanbul (ITI) freight train service was moving towards being back in business last year. Iran is standard gauge, Pakistan is broad gauge as is India. A suezmax tanker replacement takes a number of large rail cars, and there are roughly 25 tankers a day each way. The rail system takes time to travel from the available ports in Iran, to Pakistan, and then if they are friendly at the border, on to India. That works for Iran, maybe, but they would be hard pressed to have the rail stock available to do that, the shipment is one way, return is empty, so the total number of rail cars is "rather a lot". If they started pooling resources today, it would take some time to make that work, and it would still be open to sanctions, and to interdiction. If someone wants to mess with the rice bowl of others, they can and will.

You're not thinking like a Pakistani or Indian businessmen. The idea is to ship the oil in ships along the coastline to the nearest coastal oil storage site, of which there must be a few, offload it into storage, then sell it on to whoever. You could even to do ship-to-ship transfers in a suitable harbour or anchorage. No trains required, and Uncle Sam would be hard-pressed to keep tabs on - let alone interdict - those involved.

Logistics is like the rocket equation, hard to avoid the math.

• Iranian freight trains run below 140 km/hr,
• Pakistan freight trains are 120 km/hr and below.

The distance from Bandar Abass to Karachi is no less than 2800 kms...
Trains gotta go there, and then gotta go back... and in between, they have to change gauge at Zahedan. Plan on 4-day round trip as a bare minimum.
To match say 25 x Suez Max floaters, that is around 1100 large oil tanker cars, per day, so that gives a need for around 4400 tanker cars to be able to move the daily bread and forgive all x-passes etc, and deliver unto caesar etc.

Each of the tracks is, like oil line pumping stations a fixed target. The trains are better, as the tracks can be repaired and relayed fairly quickly, although bridges and viaducts take longer, but replacing of rolling stock takes a bit of effort.

Being polite and putting Humpty Dumpty back to-g-eth-er again seems like a better plan, but it takes some good will on both sides, and there is a distinct lack of that emanating from the building beside the rubble of the east wing.
