Now upgraded with a bit of metaprogramming so you can also do addition practice (for younger children), and with a bit of string manipulation can produce 'fill in the blank' questions.
Retrospectively, I should probably have written this in Javascript and put online...

Beautiful photo from the article looking west (I believe) of the Westway being constructed.

I love that Quarter Cask! The usual Laphroaig I find a bit too acrid rather than smokey, but the Quarter Cask is just so tasty.

Oh, one thing to consider is just to buy a little (compressor) dehumidifier, and run that all winter.
I did a back of the envelope calculation and the 'coefficient of performance' for warm (and dry!) air should be about 2-3. You get extra energy from the heat-of-vaporisation of the condensed water.

Drax: UK power station still burning rare forest wood
Owner Drax, which received £6bn in subsidies, continues to burn timber from Canadian trees - BBC finds.

Unfortunately these issues are very common: 'low impact' traditional activities such as burning wood and organic farming just don't scale to a world of 8 billion.
Drax powerstation burning sawdust shipped across the Atlantic from Canada is particularly ridiculous!
Far better to plant peat bogs.

Also enormous amounts of fossil (Diesel) used to grow and transport the wood.
If the alternative is 'natural' gas from a pipeline, that is almost certainly better.
Fuel oil vs. wood, if you are harvesting from nearby forests, if there are not many people downwind, would be closer run.

Indeed! But that is just one aspect.

I'm not sure the extent to which normal people understand how admin access makes laptops/smartphones perfect spy machines.

... without (Chinese) state sponsored spysoftware forcibly installed?
Similarly, my work laptop has 'Jamf connect' installed on it, which allows the university sys admin to do whatever they want on it... all the way up to automatically taking and uploading photos with the webcam.

Maybe the boring old way to do it via a script is more sensible actually; then you have a script which generates the figure, can check into version control etc. github.com/Frost-group/...
