Tesla vs. Edison: The Shocking Truth Behind Your Power! 

Nikola Tesla championed AC power. Thomas Edison pushed DC, allegedly sabotaging rivals. A battle for the future of electricity! from Tesla In The Gong

I’d like to build an #ESPHome device for data collection/display during an extended #poweroutage.

Ideas
1. powered normally via #USB / #ACpower
2. support second power source with AA/AAA battery backup: obtained easily, replaceable, no recharging
3. collect from cheap/common #Bluetooth #sensors (i.e. temp)
4. does not require a network (i.e. network down in power outage)
5. store data when #HomeAssistant is not available
6. upload data later
7. show information on a local #display

Cascade Failures, Computer Problems, and Ohms Law: Understanding the Northeast Blackout of 2003

We've all experienced power outages of some kind, be it a breaker tripping at an inconvenient time to a storm causing a lack of separation between a tree and a power line. The impact is generally localized and rarely is there a loss of life, though it can happen. But in the video below the break, [Brady] of Practical Engineering breaks down the Northeast Blackout of 2003, the largest power failure ever experienced in North America. Power was out for days in some cases, and almost 100 deaths were attributed to the loss of electricity.

[Brady] goes into a good amount of detail regarding the monitoring systems, software simulation, and contingency planning that goes into operating a large scale power grid. The video explains how inductive loads cause reactance and how the effect exacerbated an already complex problem. Don't know what inductive loads and reactance are? That's okay, the video explains it quite well, and it gives an excellent basis for understanding AC electronics and even RF electronic theories surrounding inductance, capacitance, and reactance.

So, what caused the actual outage? The complex cascade failure is explained step by step, and the video is certainly worth the watch, even if you're already familiar with the event.

It would be irresponsible to bring up the 2003 outage without talking about the Texas ERCOT outages just one year ago- an article whose comments section nearly caused a blackout at the Hackaday Data Center!
