Guy Martin proper down to earth gentleman

For those of you wondering about inertia.... imagine the big spinning metal disk spinning very fast. Imagine your hand is a motor or a kettle 20 miles away. When the motor or kettle (your hand) needs power, it puts its hand on the disk to slow it down. If the disk is small, your hand slows it quickly, if the disk is heavy and big, your hand doesn't really slow it down. If the disk slows down, the speed it is spinning slows down which takes the frequency below 50 Hz. This is called droop. If the speed drops below 49.5 Hz then the disk is automatically disconnected from the grid and can no longer power the kettle or motor. It is like a bouncer steps in and tells you to move away from the disk. All of a sudden, the amount of motors or kettles needing power exceeds the amount of power available and which is like a lot of hands on a small disk.... slowing it further.... causing more bouncers to step in. That is when the grid collapses. That is the issue Guy was explaining at the start. Wind turbines are like very small disks. Coal and gas turbines are like very heavy disks.

Years ago (late 80's) we used to work at ICI in mid-Cheshire, I used to see a bloke at work who'd quote to me that the chlorine plant at ICI Runcorn used to consume 1% of Britain's electricity....Just think of it for one moment, 1% is hell of a lot of power consumed 😮. Guy if you do read this comment that bloke was called Tim Poole 🏍!

He's a modern day Fred Dibnah. Cracking guy so is our Martin.

I don't know how to feel tbh. I spent 10yrs working there. It's traumatic see the place ripped apart. I'm glad Guy appreciated Deeside. RIP Deeside.

Wish these was longer :)

I like him. He's a learner.

Used to fly over this regularly as a gliding instructor next door at RAF Sealnd.

Thanks for reminding me about the show, off to watch it now 🙂

I wish i had a mate like guy. I love building things in my shed aswell

Excellent 👍

Much as I love this show and Guy, this seemed like they were really trying to fill the actual science explanation by just repeating the word 'inertia', as if no one has heard that word before. Would be good to actually have heard about why it's needed in a bit more detail, from the power generation to the power consumers.

Nice Guy, proper Lad, 👍👍.

worker: arc flash overalls, Guy: jeans and a hoodie. yes

6:51 Yes.... Metric FTW...

tom scott morph danced with mike rowe, i love it

A lot of generators aim for 1500rpm. It's all to do with the pairs of poles inside the generator itself. I've also seen 750rpm generators.

I can’t believe he went to Deeside !!! That’s where I live :( I wish i knew 😓😩

Guy has to have the job that dreams are made of.

I understand now, elastic band stability

Freaking love guy just wished it was on for about an hour but I'm greedy.

So I'm just assuming here but I believe this edit of the video isn't the complete edit for TV. If you noticed those black boxes that appear throughout, I'm guessing those are marked out spots where text is supposed to be.

I'm not sure what all that inertia talk was about...possibly what happens during a full load rejection? Or what happens when a large load pickup is required?

& what and why was he knocking down? Was it the same power station he'd just changed the oil filter on?

The demolition is of the old cooling towers and boilers as they are now redundant.

5 min from my house that. Should of said mate I would of had you over for a brew.

Good Lad guy always bringing us some good British tv shows they should give you the top gear show and get rid of those idiots who are doing it now your a propper presenter

Deeside has a very specialist MoD facility

you would make a good dr who !

Bitcoin mining can be used to balance energy grids. They can instantly take up the slack in quiet times and generate an income for power producers regardless of consumer demand. They can also incentivize the development of very large renewable power facilities because of this. The heat generated from mining can also be used to provide heat at very low cost, something greenhouse vegetable growers might find useful right now. They can also be used to tap stranded energy sources that would otherwise completely go to waste. There is one huge rabbit hole to fall down if you want to... There's a 38 minute documentary called This Machine Greens which explains a lot of this

So what's the connection between the turbine building and the demolition? Are they decommissioning the place?

thats not really true. If those 120tons of turbine lose their steam, they will try to coast down, but then rpm would go down generator frequency would try to go down and the grid power would start trying to keep the generator turning-like usually the grid is trying to slow the generator down by loading it and automatic systems would increase steam to maintain the rpm, but this time its the other way around.

Thing is Scotland has been able to run the whole of Scotland off of renewable electricity be it solar ,wind ,wave and or hydro since 2019 so I electricity shouldn't of risen at all when for almost 4 years now have been able to use 100% renewable engery to power the grid

if money wasnt a option what truck would you buy and want ,to do anything you need work farm and luxury

They built this power station on the edge of the River Dee near Queens Ferry,they’ve been telling us for years about rising tides and yet they built this place at pretty near sea level,at high spring tides the water level is Not far off flooding the power station,not much forward thinking there was there,we were told sea levels would rise over a metre in the next few years but built this place next to a tidal river anyway,brilliant.

What does the inertia do

4:47

Go to an offshore platform

1/4 way through the video &. No need for the music.

Great program . We should still be mining coal and using it for power the price has went through the roof because of our reliance on Russian gas it's a fecking joke.

You do know Pumped Hydro Storage Has more inertia Than A Very long Freight train \ Even some Super ships Forget you Tiny HGV A Freight Train / Supership at 5 mph would Drag you remains For the Next 2 ~ 3 miles even with the ALL emergency brakes Even going Penalty brakes Applied after impact Sadly Power usage Today isn what it use to be in the 1940s ~ 1990s ~ 2000 (All power Usage habits have changed ) Due to a abnormal loads & feeds in caused by Switch modes Power supply's and Grid Tie inverters are Altering the 50Hz(UK) / 60Hz (USA)waveform waveshape its Ment to be Sine wave but it more looking like a Noisy Square Wave that gained a few issues and isn yet causing other issues (Computers & Radio & TV radio interference even jamming Radar And upsetting Hams & AM (LW MW SW) Radio )

Ok, so that power company is spending all that money to burn all that gas to keep a turbine spun up, but NOT having it actually output any power??

Guy has just stated why clean/ green is dirtier than all other forms of power as you have to have wat for wat backed up & produced by fossil fuels or nuclear what a total waste of resources & money. I am living off-grid with alleged rentable's also wind is probably the worst as I have had 2 wind generators that have destroyed themselves not impressed & solar pv 👎not enough direct sunlight for it to work successfully in North West continental Europe.
