I think there are two types of this, only have experience with 1 so far. Within a single season, absolutely. In deep winter entering water temp (EWT) is around 30degF (this is a pretty accurate measure of bulk ground temp). Typical for w

COP of 5 when running in perfect conditions (load, EWT temps, variable stage compressor, infinite heat sink/source). You might want to research how realistic constant COP of 5 really is.

I don't think system ever met demand when commissioned (we are 3rd owners). 1st owner largely neglected the system (which I interpret as reaction to it not working well), 2nd owner had local company known for "fixing geothermal&q

Ground source heat pump owner here in the US. The original system was installed in 2007, and the loop field was designed to "best knowledge at the time". Well in the 20 years since then, NREL changed guidance on how far apart and

Those are all things I've spend some time in, I'm not sure what to say. Learning curves for each one of those things are pretty dang steep. With AI you can probably speed up learning curves, but I think you will still go on many

Expert here. When very precision molds are made, what Noctua talks about in "multiple tuning iterations are required until the geometry, cooling, gating, and moulding parameters are perfectly stabilised" is the standard process fo

Good eye! Almost like an inverted golf ball. If I remember correctly from undergrad aero, purpose of dimples on golf ball is to detach/disrupt more of any laminar flow earlier as air passes around the ball, which decreases drag. Gol

Agreed. Same or greater injection molding challenges for bottle caps, small plastic containers, things that also are in the hundreds of millions of parts annually. More challenging as they are often using polypropylene which is harder to m

I'm using Widex Allure. I only need to use one ear for now, and the low latency from the Widex was what won it, tried a couple Oticons that had a disorienting amount of lag. Also the Widex has really great high frequency transient fil

Printable PC/Nylon/ABS are not the same as the injection molded equivalents, you may want to research this more if that is an issue. I've printed every material under the sun trying to chase various material properties, and

I've found ChatGPT and Claude to be extremely helpful as guides for this sort of stuff. As long as the software has decent/good documentation for the features you are trying to create, the AI does a great job telling you how to d

99% (or more?) of human written work is filler/fluff. LLMs seem to doing a great job of reducing this by actually getting to the point. There is still a limit at which “points” can be groked, humans can only read so fast. What is the p

Autodesk deserves to be poster child for enshitification. A few weeks ago I found a video that allowed me to work around a bug in Inventor 2025 that has existed for 20 years… the video was a grainy screen capture from a Windows 97 machine!
