I think it’s more about extracting money from normies, not someone savvy enough to run a model locally. And I don’t know if they do or don’t, I was just trying to explain the comic.

Much like Amazon has an incentive to not show you the specific thing it knows you’re searching for, people theorize that these interfaces are designed to burn through your tokens.

In motor controls and power distribution, 600V three phase is low voltage. Up to 69,000 volts is “medium” voltage lol

Cold spare production floor machines. I’m sure there’s a better way, but you build the machine and put it on a shelf maybe 2 years before you need it.

- Comment on Everything is just an ESP32 away 5 weeks ago:
I’ve never bothered to reverse engineer the protocols they use between the main chip and ESP, but I have hooked the main loads, indicator LEDs, and push buttons into my own module. Air purifier, robo vacs, coffee pots, sprinkler controllers, garage doors.
The Shelly uni is awesome for stuff without dc power supplies. I’ve got one in my gas cooktop, and another in the range hood to run the fan any time a burner is on.

What’s funny to me, is that most of the trash tier connected appliances also run an ESP32 but with the opposite design goals

Not quite- these motor capacitors provide a phase shift for a second set of windings. Without it, the motor will just hum and not rotate.
You are describing bulk or filter capacitors that go from supply to common on a DC circuit, parallel to the load. These motor caps are on AC and in series with the load.
- Comment on 98 degrees upstairs, ac stopped working at 8am. 2 months ago:
Motor capacitor for an A/C compressor. A $15 part that a service company is going to charge $400 for a guy missing most of his teeth to replace in 2 minutes.

Go to a junk yard and look around the import section. Without a front bumper, it can be very hard to tell what make a car is.
- Comment on Ads when you’re pumping gas 2 months ago:
If you charge overnight, the base load is less likely to be fossil fuel. If it is fossil fuel, emission controls on a power plant are far more effective than anything with wheels.
The average car emits 400g CO2 per mile
epa.gov/…/greenhouse-gas-emissions-typical-passen…My power company emits 364g per kWh, which will take an EV about 3 miles. So that’s about 120g CO2 per mile, about one third.

Yeah it’s like 30% less heat input to melt cullet and you save raw materials. The problem is the quality impact. It’s a similar problem with paper recycling. Part of that is the fault of consumer preference, and I think that’s changing.

Some info on the challenges
- Comment on If we replace most plastic with a non plastic alternative and would that really be better? 2 months ago:
A 12 oz glass bottle takes roughly 1100 BTUs to melt the glass for. That is conveniently, roughly, 1.1 cubic ft of natural gas.
60,000 BTU/hr is a very common size for natural gas HVAC furnaces. That’s basically a bottle a minute, just to give people an idea.
There are other inputs of course, but furnace net efficiency is around 2200 BTU/lb

- Comment on Could wastewater plant simply heat up water past 500C to decompose all chemicals and output clean water? 3 months ago:
You’d have heat exchangers, like a desalination plant
…wikipedia.org/…/Multi-stage_flash_distillation
Such plants can operate at 23–27 kWh/m3 (appr. 90 MJ/m3) of distilled water.[5]
So still impossible, but not unfathomable
