Just thought I'd see of anyone I know is still here? The sky is bluer on the other side it seems...

So that people can easy (automatically) find you on Mastodon, can I recommend you put your mastodon address in your Twitter BIO? This can be used by automatic tools like debirdify.pruvisto.org (which I recommend using) to copy all of your Twitter follows on to Mastodon?

@betateach @g__j A friend is having a bit of a Kafkaesque experience getting @OctopusEnergy to install a heat pump. Their gas boiler's broken, so now's the time. The house is a good fit for a heat pump with a good amount of insulation and some under floor heating, great! Well…🧵
This thread is well worth a read on how to install insulation - the devil is in the detail!
This type of air movement, known as thermal bypass, comes in two forms,
* Open loop
* Closed loop
I’ll explain them shortly but first, let’s get our language straight.
* Air gaps occur on the warm side
* Cavities are on the cold side
* Joints are between abutting interfaces

This is worth a read, and not as negative as the headline implies: "No 10 is understood to be pushing for two big reforms. First, decoupling electricity prices from the global gas price – not least as renewable energy is now nine times cheaper than gas."

Clear thinking on digital security, regulation and one of the more damaging speculative bubbles du jour, in this episode of The Changelog podcast. Essential listening for anyone who uses (and especially makes) tech!

Not sure whether I'm glad that Clive pointed out these cursed products. I live near to two large schools (11-16 yrs). My workbench is now lightly nicotine infused, and I'll soon have enough LiPo cells for the world's first strawberry scented DIY PowerWall. youtu.be/N65DpT2nqEI
Good chance of seeing the Aurora Borealis tonight especially between 22:00 and 24:00 in the northern half of the UK. Maybe even from the southern half if you're lucky (try to get away from light pollution, the further south you are the closer to the northern horizon it'll be).
The CME arrival last night brought minor geomagnetic storms. With enhanced geomagnetic conditions, there is the chance for further aurora sightings across Scotland and Northern Ireland tonight, and possibly across the north of England if strong geomagnetic activity occurs
An important message from the Australien govt regarding the recent record breaking floods... youtu.be/PvFy2TuPDaw

Fascinating visualisation! @BioProfBarker
@jleightonphoto if you can find a decent local heat pump installer, there's a £5k upfront grant available from a few weeks' time. Will be a lot cheaper to run than your oil boiler, but install costs vary widely depending on the existing building fabric, and radiators etc.
Corruption, illegal parties, and a slow slide into fascism.
Your government is currently drenched in illegality, so maybe don't point fingers right now.
As for the law you tried to pass last night... It promotes the forceful suppression of peaceful opposition, which allows me to say this:
You're a fascist, Priti.
Hello @britishgashelp I found one of your gas smart meters on the pavement near where I live. From its condition it looks like it was accidentally left there by an installer. Please can you DM to arrange to have someone come over and pick it up? I'm not a BG customer.

Is it "anything you like, as long as you don't blame him for anything, turn a blind eye to the backhanders, and keep voting for him"?

Great overview of the process of getting a heat pump for your home!
Our interview with @EmmaBohan from @IMSHeat is out where Emma discusses heat loss calculations, heat pump sizing and the difference between air source and ground source heat pump systems: renewableheatinghub.co.uk/wh…
For anyone with an interest in solar (passing or otherwise), the annually aired and refreshed opinions of @solar_chase are well worth your time...
1. Time to make 2021 minor updates to my annual “opinions on #solar” thread.
If you like these, you’ll like my 2019 book, Solar Power Finance Without the Jargon, a little old but still valid, five stars on Amazon.

Nice overview video for heat pumps for domestic heating and hot water...
We have an interesting conversation with @JeremyClimas covering a wide range of topics from correctly sizing heat pumps, the importance of heat loss calculations and the evolution of refrigerants in heat pumps: youtu.be/6CDL4hwYrtU
