this is silicon metal surgical siliconE has density almost equal to water

this also happens with dc once voltage is high enough

that bot setting is just irl evil bit

hornyposting on main must be one of these elusive family values then i guess

AC also needs to deal with line resistance, and cheap, efficient multi-MW, multi-kV DC/DC converters aren’t there so far, but there are prototypes (and drop-in transformer replacements https://en.wikipedia.org/wiki/Solid-state_transformer) Advantage is that these converters can be more efficient than transformers and you don’t have to deal with reactive current (if DC). Obvious downside is that frequency control isn’t there

if power electronics get a bit better than they are now, we could switch to DC power transmission and DC/DC converters instead of transformers. bunch of infrastructure could be replaced one by one, but benefit is slight except for already used undersea cables

but on generation side, it’s either photovoltaics or spin a magnet

It’s easier to see that this circuit is rather symmetric when you redraw it

Then with both switches closed blue wire (the one in the middle) should only carry small current. If both halves are exactly the same it should be zero

In general when circuit doesn’t include nonlinear components (semiconductors most commonly) you can sum two valid solutions and you’ll get another valid solution. Note that when one switch is closed, current in blue wire goes one way and when the other is closed, in opposite way

there are still coal powerplants around and any replacement is better. geothermal doesn’t work everywhere

Coal ash (from some mines) contains so much uranium that if emissions like this were detected near NPP all hell would break loose, but nobody cares. Energy content of that uranium can be higher than what was released during coal combustion

it replaces gas turbine with a fuel cell, which is a good couple % more efficient than CCGT. still under development. there is also another variant where hot offgas is generated under pressure and expanded directly. no steam, same effect

there is a power generation scheme that uses high temperature fuel cells. optimally it could run on hydrogen only, but because it runs hot, it is able to take almost any flammable gas, along with some steam, and it forms hydrogen internally, then oxidizes it. this alone generates bulk of electricity, but offgas is hot, so it goes to heat exchanger which boils water, which then turns steam turbine

if it’s that thick, i expect it’s some kind of pharmaceutical dissolved in oil. over time oil, like sesame oil, will gum up and darken like this

Fair. I’m doing synthetic chemistry for a living, and probably i have as much use of electrochemistry or crystallography as you do have of organic chemistry. I get it is a skill with a limited utility, and i might be biased, but i don’t get why people complain about it so much. On the other hand, one of my labmates was hired by mat sci lab as a single person fire brigade to unfuck their project, ant it worked despite no organic chemistry involvement

if you don’t mind, what field are you in that you were examined in ochem but you don’t use ochem? last time i’ve checked, chatbots crap the bed constantly when asked about anything that you can deduce (easily, by analogy) but can’t find, especially as text, the mistakes were either glaring or sneaky but never correct. it’s much easier to express what you mean by drawings in ochem anyway

some variants go above 2.4GHz but going over 5GHz is entirely different thing

pringles can would work okay for 5ghz but making feed element for that band would be hard without expensive test equipment

pringles can is too small, you need a can 8cm in diameter minimum. 400ml cans won’t do but bigger ones, 800ml, 1200ml will work https://www.wikarekare.org/Antenna/WaveguideCan.html
