If you're going to mess with electricity, at least have the fucking decency to attempt to live up to code. Found these horrors hiding behind a wood panel today, while I was tearing down my old kitchen.
The power supply in Russian-occupied Sevastopol was cut off on the evening of 16 June as the automation of the Sevastopol electricity substation was disabled.
So the #energy#Germany imports to substitute for nuclear is mostly #renewable.🌻
Yet the internet if full of bs memes about how germany switches of "clean #nuclear" (its not clean) to use and buy dirty #coal made #electricity (it doesn't).
I'm not even sure it would be possible to install a SuperCharger there. The whole town's current #electricity#supply is probably only a few hundred kW - the existing #infrastructure probably does not have the excess #capacity for a single 150kW charger, much less a pair of them.
If you're thinking about #traveling from #America to #Canada this summer for #vacation, keep in mind that while they do have the same kind of electrical outlets and power (120 volts, 60 Hertz), their phase is shifted 45° to the left. So don't forget to #pack an adapter.
Would it be technically possible to gradually upgrade the grid in the USA from 110 V (60 Hz) to 230 V (50 Hz)?
Perhaps by mandating that all new installations should be able to handle a future switch? Or perhaps by going street by street, house by house, and switching it over?
Power has been restored! Apparently a wayward squirrel 🐿️ somehow shorted out a transformer two blocks away knocking out power to 83 homes. I'm sorry for his electrocution but thrilled Ameren (Union Electric if you're my age) is as good as they are at fixing problems.
1/34 This started out as a much shorter thread about a related topic, but Something Happened and now it's a #LifeHack#instructional thread on keeping your house comfortable and saving #money and the #environment, through the magic of air movement. It's also timely, what with it being the start of the northern-hemisphere summer and southern-hemisphere winter.
7/34 First step you can take? Change the #fan setting on your #thermostat from "auto" to "on" (always on). With modern HVAC systems, the #circulation fan is generally pretty efficient; keeping it on uses some #electricity, but #saves more on the heating or cooling demands, so it's a net #benefit.
Modern furnaces will commonly run their fan at a lower speed when not "on cycle", giving you enough air movement but using even less energy to do it.
"Scientists Find a Way to Harvest Clean Energy From Nothing But Air
Engineers have demonstrated something marvelous. Almost any material can be used to create a device that continuously harvests energy from humid air.
It's not a development that's ready for practical application, but it does, its creators say, transcend some of the limitations of other harvesters. All the material needs is to be pocked with nanopores less than 100 nanometers in diameter. That's around a thousandth of the width of a human hair, so easier said than done but far simpler than expected.
Such material can harvest the electricity generated by microscopic water droplets in humid air, according to a team led by engineer Xiaomeng Liu of the University of Massachusetts Amherst.
They have called their discovery the "generic Air-gen effect"."
Engineers use nanotechnology to pull electricity from thin air?
Researchers at the University of Massachusetts Amherst have discovered a method to harvest continuous electricity from air humidity. They say a device using their tech could be capable of delivering kilowatt-level power.
Not sure if this is a pipe dream or another one of those "good news if scalable" stories but the science seems cool!
The price of #electricity in #Europe has been quite something. Last summer it was climbing to €1000/MWh, now it's very often below zero during the day. Yes, you have to pay someone to consume it.
I'm glad I've got a home #photovoltaic system primarily for environmental and self-sustainability reasons because any ROI calculation is basically impossible.
After cutting Russian power imports, Finland struggled with producing enough energy and citizens had to restrict their use. They have transformed their system so much that they're having to reduce output from nuclear stations. They aim to have wind power as the primary means of production by 2027.
@dmoser
The Achilles heel of #electricity is requirement of conversion for storage.
Do you know a calculation H2 vs Li-Ion in cars? I wonder if it is still 1:5.
"The dispute is an early glimpse of the type of fights the U.S. will face as the warming #climate supercharges drought, wildfires, storms and floods, forcing wrenching choices over which communities get protected.
#California's proposal would almost entirely cut off #Colorado River deliveries to Phoenix, Tucson and the 11 Native American tribes getting #water from central #Arizona’s primary canal before California’s agricultural users would face any mandatory cuts."
"The states along the #Colorado River — a vital source of #water and #electricity for the American West — reached an agreement with the Biden administration to #conserve an unprecedented amount of their water supply in exchange for $1.2 billion in federal funding, state and federal officials said on Monday."

Worth reading the whole article, as these events will become more and more frequent....
