Looking at pricing for smoke alarms, and I simply cannot believe that Google are killing Nest. They're 2-3x the price of other smoke alarms - how can you not be wildly profitable at these levels?

I have very much fallen out of love with Google hardware. They EOL'd Nest smoke alarms, and I've had it with their Wifi pucks. I'm just waiting for them to kill their thermostats.

Ubiquiti kit ordered. Any advice on smoke alarms?

About 12mWh less gas consumed than in previous years. Reasons:

- Mild weather
- Internal insulation for every wall and ceiling in all upstairs rooms
- Low temp underfloor heating everywhere
- Solar thermal in summer (very evident on chart)

(Good year for solar PV too: 50% of home plus two cars)

This beggars belief.

It is insane to be spending almost twice as much upgrading the UK's gas network than its electricity network. The gas network must quickly become legacy, not future-proofed.

Nils "nominative determinism" Pratley at it again.

If only there was some magical technology that could multiply the calorific value of the limited gas by 3-4x, then all our heating worries would be solved.

Oh wait, there is.

Heat pumps = energy security.

That @joneaves.bsky.social fella is fine company, highly recommended. Didn’t try to factorise large primes even once.

While I do not condone violence, there is straightforwardly no equivalence between antifascists and fascists. Feels like Germany has gone down this path before and it did not end well.

This is an excellent piece on graphs and semantics. Very balanced and well researched: substack.com/inbox/post/1...

Hey journalists! I know you're very smart and literate, but you are not very numerate.

This should say "your already very expensive shopping is going up by another 3.6%" Instead you imply things are getting better for me, rather than getting worse at a slightly slower rate than feared.

Not so much solar power in these Autumnal days. Elon pushed a new firmware update to my batteries that is "smarter" and greatly limits the amount of (cheap, off peak) electricity I import.

Now I don't have enough battery power to get through the day if I do laundry etc.

JFC. Seems like the UK Labour policy wonks have been kicked in the head by a horse.

The alternative: Tax heavy polluting vehicles properly, including stupidly large EVs, through VED.

Stop subsidising fossil fuels. Increase benefits for low-income people to offset the removal of said subsidies.
