It was absolutely fascinating - I learnt so much while chatting over tea. Strongly recommended.

I measured the effectiveness of some insulating blinds.
They are surprisingly good, with a U-value of about 1.6 W/°C/m^2.
The article contains more details than most people want to know.

A detailed look at 12 days operation of a heat pump in winter. It's a long boring article that will only be of interest - marginally - to heat pump aficionados.

After 4 winters, the capacity of my Tesla Powerwall 2 is declining by around 0.4 kWh per year i.e. about 3% of its nominal 13.5 kWh capacity.
Round Trip Efficiency approaches 90% in winter, but falls to 80% in summer.
Do you have any similar data?

A précis of the state of the Hinkley Point C Nuclear Reactor Project in the UK.
It ends with the lines:
"...but whether it will be seen as a good or a bad choice in years to come remains to be seen."

Friends, here's a summary of the performance of my 5 kW Vaillant Arotherm plus heat pump over the last 176 weeks - 3.5 years.
The effect of the radiator replacements is now very clearly visible.

Rosie discusses the - frankly under-appreciated - role of engineering (as opposed to science) in the scaling of new renewable energy technologies.
It's a really important point with which I think Bill Hammack would agree.

If your boiler emits a big cloud of mist when it's operating, then this indicates it is not optima;;y adjusted.

When the air temperature is just above zero, heat pumps need to periodically de-ice their heat exchangers. In this article I take a look at the effect of de-icing during a recent cold-snap.

In October I changed most of the radiators in the house.
Has this affected heat pump performance? Yes!
In this article I compare heat pump performance in November with November 2023. The weather was similar, but the COP improved by 17%.

This is a short, moving documentary on the issue of pensioner poverty in Germany.
Seeing these issues in other countries helps me reflect on the same issue in the UK.

@dwnews fascinating video looking at the issue of abandoned oil wells in Texas, and by implication in many other fields worldwide.
The capped wells eventually leak and emit methane and contaminate the groundwater.

Excellent discussion of the latest report from the Global Carbon Project @gcarbonproject .
It's an hour long but full of fascinating detail.
Summary: we are probably close to peak emissions, but we are not there yet. And then there's the path to zero...

Rosie Barnes rarely indulges in speculation, but here she takes a look at how the possibility of EV wireless charging might affect the transport and energy landscape.
It's still a little way off, but it could be quite significant.

Grady from Practical Engineering takes a look at how the Electricity Market works.
It's US focussed but there is a lot that is relevant to the UK.
Enjoy 🙂

If you have solar panels then you need pigeon protection. Sadly the protection was not installed with the panels back in 2020. And so today, after 4 years of prevarication, we finally installed pigeon-proof 'skirts' on the PV arrays.

https://protonsforbreakfast.wordpress.com/2024/11/10/how-much-of-my-body-is-made-of-fossil-carbon/
As best as I can make out, about one fifth of the carbon atoms in my body were originally in a fossil fuel deposit.
The estimate is highly uncertain, but even so, I find it indicative of just how profoundly we have disturbed the carbon cycle.
I'd be happy to correct by estimate if you spot an error!
