It would be much easier for Nick to start whittling.
Or learn something really useful, like the clarinet.
A clarinet would be too complicated but I whittled myself a bamboo flute once, like the one Kwai Chang Caine from "Kung Fu" carried around on his back.
I couldn't get a note out of it but I didn't know if that was a result of my poor whittling skills or my lack of prowess as a flautist.
Perhaps a 3D printed one would be an improvement...

You meantioned 3D printers. I actually got one last year. Printed a Benchy, then a bigger one.
Can you print me a 70' x 6'10" one please?

On the other hand, fascinating that a multitude of fossilised lurkers have suddenly sprung to life! Must be something in the water at this time of year.
My email inbox was suddenly full of CWF notifications of new posts by Gibbo and Chris W after years of dormancy so I found myself sucked back into the mire.

Furthermore, there is another loss which hasn’t been considered quantitatively.
Take the 2 identical lead acid batteries in the earlier example. One discharging at 5A for 10 hours and one discharging at 50A for 1 hour.
Let’s assume the batteries’ initial internal resistance is 5mohm (a typical fully charged figure), though the actual figure is not relevant to the argument.
The energy lost through heat in the first battery will be:
i^2Rt = (5^2)(0.005)(10) = 1.25Wh
The energy lost through heat in the second battery will be:
i^2Rt = (50^2)(0.005)(1) = 12.5Wh
ie: the second battery will dissipate 10 times the energy compared to the first battery, owing to its internal resistance. This energy (in both cases) is unrecoverable.
Further, the internal resistance of the second battery will actually increase at a faster rate than the first battery as it becomes discharged more quickly. So, in reality, the second battery will dissipate even more energy owing to its internal resistance’s increase.
However, this is not what Peukert is about. Peukert is analogous to a car, whose fuel consumption is quoted by the sales person, when asked, as “30mpg”.
Now, we all understand implicitly that means, driven steadily, our fuel consumption should be as quoted.
We also understand (implicitly), that if we were to drive the car for an extended period at 80mph (where permitted!), we would not expect to obtain 30mpg.
Peukert is a mathematical way of describing those “high speeds” in a battery.
Not him again!

If it's a cold winter you can charge your batteries with them and go boating.

Some of the original navigators who dug the canals ended up living on the cut in dire conditions. Not necessarily in boats either.
Let's hope that there were more of the bleeding heart brigade around back then rather than heartless judgemental tories who make negative assumptions about people they've never met and have no idea about their lives, needs and hardships.
No doubt there were ignorant folk about even then who said that they should get themselves a job and pay their way rather than just be worthless freeloaders.

My immediate thought was a hulk like the many dotted around the Thames Estuary but, looking at the size in relation to the buildings and waterway and what looks like a structure on the vessel...Some sort of fish farm perhaps?

"Ponty Still Lit"
Is this the definitive pronunciation then?
I've always pronounced it "Pontywotsit"

Shame, might have just asked you for a couple
I can be persuaded but I am no longer reliable enough to do it professionally as I can be fit and healthy one day and bed ridden the next so deadlines and commissioned work are a thing of the past.
The last rug I made was for someone who didn't care how long it took.
I'm hoping to build a loom with a continuous warp system because putting a warp on the loom is by far the most work intensive part of the process but it is difficult to get the required tension for rugs without a fixed length warp.

Thats nice. I'm glad it works for you.
Well it pays the mortgage and maintains my boat habit so it definitely works.
That said I rarely make rugs these days because they are hard work and my health isn't great.

If you have to keep making more of them because they keep falling apart does that not mean they're pretty poor quality regardless of your good quality tools.
Well I keep making more of them (proper rugs, not rag) because folk keep buying them.
I don't make rag rugs unless someone is prepared to pay me a lot of money for them.
I do have one in the bathroom that I made about 20 years ago.
I still have the frame loom I made it on too.

Yes they dissolved in November 2017 according to Companies House (the company, not the props).

I don't keep anything I don't really need and if you're not going to make another rug it's just more carp to find a home for. If you want good quality hard wood and a frame that lasts then all power to ya, I on the other hand don't want a house full of rag rugs (or looms for that matter) nor do I want to go into business, I was relaying my aunts experience and I guess different people want different things from their things. I'm sure the OP can make his own mind up about what he wants.
If you want one good quality rug that the warp doesn't start spreading after 5 minutes then you will need a strong frame that will maintain tension.
If you use a floppy softwood frame then you may as well store it because the rug will fall apart and you'll be making another before too long.
Poor quality tools make poor quality products.

My aunt used to be rag rug daft, she used to make her own looms. It's actually incredibly easy and you can find loads of videos on how to do it on YouTube. Making your own is really easy cheap and when you've made your rug (unless you want to make more) you can bung the loom on the fire because they're a pain to keep or give it off to a charity shop, buying one makes it harder to get rid off I think.
The problem with homemade loom frames is that they are usually not strong enough to maintain a strong even tension in the warp and so the rug doesn't last long.
That said if all you want is rags prodded through canvas or sacking then you don't need a loom at all.
It all depends on what you are after.
I'm not sure why they are a pain to keep.
The frames I make flat pack and take up very little room.
They are also made from good quality hardwood so they are not a cheap source of firewood.

I occasionally make them but actually getting the quantity of rags for a big one makes them commercially a nightmare.
You end up buying material to make rags and, as I don't have a trade supplier of rags it works out more expensive to make a cheap crappy rag rug than a quality wool one.
If you want to have a go I can sell you a nice frame loom though.
Peg looms don't make durable rugs btw.
Edited to add... You can get fairly cheap ones off ebay which are pretty good quality and loom woven.

I have tried to find out the name of the programme for a number of years as it was a bit zany and nutty to watch and quite funny.
"End of part one"
Later than early 70s though because I didn't hit my teens until 79.
Edited to add : 1979-1980 according to... https://www.britishclassiccomedy.co.uk/end-of-part-one-1979

Reading the blog it appears that he had a similar success rate as I had with my Easicool fridge in my 1960 Bedford CA camper. It was simply an insulated box which you poured water through a mesh in the top which cooled by evaporation.
It worked better the warmer the weather but didn't work at all on warm wet days when milk just went off.
No computers though.
