@TechConnectify Do a retrospective on attic fans (I think people call these “whole house” fans these days). These were super common in the South in 1950–70s construction:https://www.energy.gov/energysaver/cooling-whole-house-fanI haven’t seen one of these in decades.

@TechConnectify great! I keep putting off buying one. I guess that’s going to be more than I need to know to finally get to it.

@TechConnectify What blew me away was the runtime of over an hour 😵

@TechConnectify Over an hour, but not long-winded! Also that differently-shaped notch bothers the heck out of me too! I'd absolutely take a file to it!

@TechConnectify just watched it through, this is fantastic not just from an entertainment perspective but also a research perspective. Very cool!

@TechConnectify Great video. Thank you! I’ve got 8 ceiling fans in my house, and it’s…fantastic. I’ll show myself out.

@TechConnectifyHi Alec,I noticed you just released a fantastic video on how usa keep messing up ceiling fans! Given your love for residential energy efficiency and motor design, I think you should do a deep-dive episode on the electronic wizardry inside "BLDC Ceiling Fans." They are incredibly popular in India right now (pioneered by a company called Atomberg), and they represent a massive leap over the traditional single-phase AC induction fans usa use in the West. Here is why they are a perfect fit for a Technology Connections episode:1. The Efficiency Leap: A standard AC induction fan draws about 75 Watts at peak speed. A BLDC fan delivers the exact same airflow (around 220–235 CMM / 8,000 CFM) while drawing only 28 to 35 Watts. At low speeds, they run on an unbelievable 2 to 3 Watts.2. Hidden Inverters: Inside the fan canopy is a sophisticated circuit board. It takes incoming AC wall power, rectifies it to DC via an internal SMPS, and then a microcontroller uses Pulse Width Modulation (PWM) to step it back into a simulated 3-phase AC wave to spin a permanent magnet rotor. It ties perfectly into your older video on how induction motors and 3-phase power work!3. Absolute Silence: Because they don't use old capacitor-drop or resistive wall regulators to chop the AC voltage waveform, they never experience that annoying low-speed electrical motor hum. They run completely silent.4. The Engineering Trade-offs: Traditional fans are "dumb" copper and iron machines that can survive a lightning strike and last 40 years. BLDC fans put an entire computer motherboard into a hot, humid ceiling environment. If a power surge fries the PCB, the fan is bricked. Furthermore, they are native to 220V grids—running one on a standard 110V North American outlet requires a step-up transformer, or the internal chip throws an under-voltage error.They cost around $37 to $59 USD in India (though shipping them over to the US pushes it past $220 due to freight). Seeing you tear down the internal circuitry, explain the electronic commutation, and benchmark the power draw using your power meters would make an incredible video. It represents the exact kind of "invisible engineering" that makes household appliances so fascinating.Thanks for the great content!

@TechConnectifyDid I miss it or did you get through 1:11 without mentioning the word punkhawallah? The punkha (or pankha) was the predecessor to the ceiling fan and was often operated by a punkha wallah, who was paid to keep the punkha moving. It dates back to 8th century Arabia.Because ceiling fans replaced the punkha and the wallah they were sometimes called punkhawallahs. The word lives on in the 'Punkah Louvre', the kind of device you'll find above your head directing air towards you.

@TechConnectify Thanks a ton for having a Mastadon. Wish more folks realized Bluesky is kind of a dead end. Hope you've been enjoying your stay!
