If the LotR were created by GRRM, we wouldn't even get to read the part where Gandalf "died" before all of us has left our mortal coils behind...

This works well but it's hard to see if someone's done it right. when sailing I coil in a figure-of-eight, either by hand or with one end around a winch.

I like the neon coils of dog poo.

from this video: https://www.youtube.com/watch?v=7jqImhd8Ggc you can see that he's coiling copper wire around a pipe (using a lathe to save time).

That's fascinating. I wish the Amazon proprietary cell had been included!
What are the copper coils usually used for? Pipe heating?

OK, hold the fucking phone here. This video is just a disaster. It is flippant and glossing over the facts of what actually happened. This story is a favorite of mine, so I have done a lot a reading on it.

This happened in 1983 (36 years ago).

>> Do planes seriously not have a fuel gauge?

There is specifically a digital fuel gauge processor on that plane, and it was malfunctioning. There was an inductor coil that wasn't properly soldered onto the circuit board. At that time, planes were allowed to fly without a functioning digital fuel gauge as long as there was a manual check of the fuel in tanks and the computer was told the starting fuel.

The problem is that fuel trucks pump by volume and planes measure fuel by weight. The fueling truck converted the volume to kilograms and then converted to pounds. He should not have used both. In 1983 ground crews were used to converting volume to pounds. The 767 was the first plane in Air Canada's fleet to have metric fuel gauges.

The line in the video "the flight crew approved of the fuel without noticing the error" glosses over how it is actually done. The pilot was passed a form that contained the numbers and calculations from the ground crew that stated that 22,300 kg of fuel was loaded on the plane. The math was wrong, but unless the pilots re-did the numbers by hand, there wouldn't be anything to jump out at them. He accepted the form and punched those numbers in to the computer.

The 767 was one of the first planes to eliminate the Flight Engineer position and replace it with a computer. There was no clear owner as to who does the fuel calc in this situation. In this case, it fell to the ground crew.

>> I would hope there is a nit more of a warning system than the engines shutting off.

If there was a functional digital fuel gauge, it would have showed them missing half their fuel from the start, and the error would have been caught. Because there wasn't, the computer was calculating and displaying the amount of fuel based on an incorrect start value.

That is another problem with this video. It states that "they didn't even think about it until ... and an alarm went off signalling that their left engine had quit working."

Fuck you, narrator asshole.

In this case, low fuel pump pressure warnings were firing off before the engines shut down. They were investigating why they would be getting these low pressure warnings when their calculated fuel values (based on the original error) showed that they had enough fuel.

>> I can't believe the pilot's were given an award for causing an avoidable accident.

The pilots did not cause it. They followed all the proper procedures applicable at that time, 1983. It was only due to their skill and quick thinking that the pilots landed the plane without any serious injuries to passengers.

They ran simulations in Vancouver of this exact fuel and flight situation and all the crews that ran this simulation crashed their planes.

"Bad math can kill you." Flippant, correct, but still not quite applicable to this situation. Air Canada did not provide any conversion training for dealing with kilograms and the 767. Not the ground crew, nor the pilots, were trained how to handle it. They were expected to "figure it out". That, and the elimination of the Flight Engineer position, set these situations up for disaster.

It's called an electric nail....it's a temperature controlled coil around a glass bowl, you put your shatter/oil/weed in the heated bowl and don't use fire.

We also dont have the facilities in place to mass produce steam engines or build pyramids in the traditional way. Or computers - roll your own coils for memory, anyone?

Interesting, not disturbing.

I'm pretty sure the stupidest war ever was the War of Jenkins' Ear, which not only was dumb in it's own merit but also spawned two additional wars that killed close to 2 million people.

Basically Britain and a trading company decided that a little war would help to spur trade, so they seized on an 8 year old incident involving the Spanish boarding a ship and cutting off the captain's ear to fan the flames of conflict.

While the casualties of this little conflict were only around 30k dead or wounded, and a paltry 500 ships, it nicely helped kick off the War of Austrian Succession. That fun conflict led to around half a million dead.

Not satisfied, the powers of Europe stewed over the previous two incidents and then decided to really get down and dirty. The Seven Years war was the first really 'global' war, involving every European great power of the time and spanning five continents. Roughly 1.25 million people got to shuffle their mortal coil off the world thanks, in part, to a little trade war over an ear.

Excitement for my plans to make myself a 9 string bass with the highest string betting guitar, using one single curved back neck in the creation of a dual fretted/single 9 string/highest guitar string etc. Opposing faced, designed to accommodate the most coil pickups/hummbuckers I can fit/ make fit. Farraday caging the parts with inconel 600 non magnetic foil (aviation grade). Use non solder crimping connections, platinum cable/wire & connectors with graduating switches/transition low to highest setting etc. Built in anti surge devices, connection.

Whoa. I had never thought of that.
Cumulative of all the coils.
Cool.

I wondered that too, but the pressure it produced (see 1:33) seems to argue that it's the cumulative height of all the coils added together (not just a multiple of the maximum height, though, because each successive coil is shorter).
That's just my guess, though.

Live long enough and you don't have to hear one of the most annoying sounds. CRTs might have more or less gone the way of the dodo, but coil whine can strike at ANY TIME!. If you can't hear it take it as a blessing cos irony is a thing and so is tinnitus.
