Heat and power

I have district heating from a combined heat and power plant, which should be 80+% efficient. A solar air to water heat pump could be more efficient at 29% * usually 200% but sometimes 400% (For reference, traditional gas boilers only go up to 94%.) = 58% to 116%, the latter might require ground instead of air. CO2 is a relatively safe refrigerant.

According to ChatGPT: The efficiency of a typical modern steam turbine in a power plant is around 30-40%. Fuel cells can achieve efficiencies in the range of 40% to 60% or even higher for solid oxide fuel cells (SOFCs). Those and molten carbonate fuel cells (MCFCs) are used in combined hea

Windows sucks, too!

Audio

Needs a registry hack to stop audio pops.
Windows 11 TTS stops working randomly.
64-bit Windows 10 Home version 1909 build 18363.900 (and probably 11) lacks audio enhancement tab. Turns out MSI decided to change that to Realtek Audio Console, Sound Effects, Nahimic, Effects ON, Volume Stabilizer.
Audio mixer sucks since 11. Doesn't show the Xbox game bar making noise, eg https://www.youtube.com/watch?v=uNCQzwPptbA
Settings app fails at volume mixer and Bluetooth settings, unlike the settings popup from the systray.

Apps

If you don't learn from the past you're doomed to repeat it.

Dell
Latitude 5501 sounds even worse than my MSI MS-16P7 due to ratting its plastic case. Interviews sound like a poor phone connection. Iron Maiden - Can I Play With Madness on the other hand is tolerable and even has some bass, almost enough for Robbie Williams - Angels, which sounds like a not-quite-tuned FM radio for the vocals (too little power), particularly noticable on U2 - Discotheque. Without "audio enhancements" disabled, its audio jack adds a rumble to videos like this. Worst audio hardware I've ever used, especially playing this. Then again, using my

Coal ash contains more energy than was gained from burning the coal.
