Do you have a social life? No, I have a social cupboard!

“Fool’s chocolate “

Old meme. There is a picture of a girl clutching her throat in disgust.
A plate of cookies is labelled “STOP!! LOOK CLOSE!
WAIT!
LOOK AGAIN!
FOOLS CHOCOLATE!!
DON'T BE FOOLED!!!
Raisins can be anywhere! Vigilance is your only protection against the dreaded fool's chocolate.”

I have also used a children’s plastic climbing frame toy (Quadro) as a nonmetallic support for antennas, and the company kindly gave it me for free in return for some pictures of it in Greenland!

“By the year 2000, oil may be in short supply and extremely expensive. One solution is to return to coal…”

FUTURE TRAINS?
Speeds have risen a great deal since the Rocket's 46.7 km/h, and the present record is 380 km/h. One far off possibility is a train powered by a linear induction motor. A LIM train is powered by a type of electric motor, which, instcad of rotating on a shaft (like the one in a model train), is swept along a metal track. The track would be very expensive to build however.
Adventurous innovations like this are unlikely to be
developed commercially in the near future.
By the year 2000, oil may well be in short supply and extremely expensive. One solution could be a return to coal, of which there are immense reserves.

alternative to diesel trains.
Looking far into the 21st century, clectricity will probably be generated by a combination of nuclear fusion, wind, solar and tidal power systems. The incredible train shown on the right could only be built and run using the torrents of cheap power that such systems could provide.

A few more bits of material for you from my Usborne Book of Supertrains:

@grindrod.bsky.social got your book sir! Looking forward to it!

“Comment vas-tu, Mike?”

I am standing outside in front of a lorry, making a sour face and shrugging. On the van it says “bof”. (This is a French slang word that’s a bit like “meh” in English)

Here’s one I’ve been to. That dome is on skis, can be pulled by tracked vehicles.

An old friend of mine will say “look, the Pope!” and point over his shoulder before stealing a chip off my plate. Today I walked along Park Place in Cardiff: look, the Pope!

My colleague Tommy was given the job of briefing Anne and her husband on how to drive the snowmobiles. Once they had got the hang of it, he and their protection officer let them go off on their own on a safe bit of glacier. The officer said it was a rare opportunity for them to be alone together.

See also the logo of the governing party of Singapore: upload.wikimedia.org/wikipedia/co... In both cases the lightning bolt suggests power and action and hurt directed at the party’s enemies, so not a great logo for a nationalised train company!

Yes they are! Water on glaciers often appears blue too - I don’t entirely understand the physics but it’s to do with how the crystal structure of the ice absorbs red and green light

Found this photo of Eurostar’s Emergency Chocolate Cart. The chocolate has now expired, presumably it was destroyed in a controlled fashion… #emergencychocolate #chocolate

Airline style aluminium cart. On the top is a paper label that says “EMERGENCY CHOCOLATE CART EXPIRE DATE IS 30/09/2025”

I'm not a huge fan of Substack but I tolerate it. However, a recent innovation seems to be a "this post is too big for email" banner designed to increase click-through conversions and app interaction stats. Dishonest and unncessary. (and yes, I'm aware that Substack has many worse issues).

A screengrab from a substack page. Underneath the text, a yellow box appears with an exclamation-sign roadsign symbol saying "This post is too long for email" and a button saying "Continue in the Substack app")

I have made a tear-off Darkness Calendar for the winter. Every week I can tear off a page and get the sunset times. It starts next week and runs for 14 weeks, by which time we’ll be back to sunset at 1700 here in Cardiff.

Thanks a heap, Microsoft. You were supposed to make collaboration easier. (Yes, I know Microsoft are bad, but it's what the institution provides so we're stuck with it)

Don’t buy a Mous phone case. I’m on my second one (a warranty replacement) and it’s already failed the same way as the first one - the rubber has come away from the hard plastic.

On my ride into work this morning I saw that HMCS Montréal, a Canadian frigate, was visiting Cardiff. I stopped by to speak to the sentries: Me: "Good morning, welcome to Cardiff! Did you find the Tim Hortons yet?" Sentries: "There's a Tim Hortons?!" @timhortonsofficial.bsky.social

We are being held up by a technical problem in the Channel Tunnel - probably an hour’s delay. Fortunately I spotted that there is EMERGENCY CHOCOLATE in the cafe car! #train2egu #emergencychocolate

My local hardware store only had 2mm nylon cord - I think for a proper version I'd go up to 3mm or 4mm climbers' accessory cord (aka cordelette) - but I'd need to check that it'll go through the loop on the bath plug!

In my job I do a lot of logistics - packing and unpacking, shipping and labelling. Last year, whilst doing fieldwork in Canada, I thought "wouldn't it be great to have a gaffer tape dispenser on my belt?". Behold, the prototype! #fieldwork #logistics #glaciology

I have a PhD studentship available for a UK-resident mechanical engineer, physicist or engineering-minded geoscientist - developing a free-floating probe that'll travel through water channels inside glaciers in Greenland! www.findaphd.com/phds/project... #glacier #glaciology #phd
