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

doesn't matter because you have to purify it anyway

direct hydrogen uses that make sense given hydrogen is cheap are ammonia, methanol (also from biomass), steel and generally speaking fine chemicals. methanol and ammonia can be used as fuels for cases where BEVs don't work, like shipping. this also requires monstrous overbuild of power grid

prerequisite for cheap hydrogen (cheap electricity) will also make further electrification make sense and that eats lunch of hydrogen use for power even before hydrogen infra buildout happens

for hydrogen propulsion to make sense prerequisite is to have lots of cheap green hydrogen, which mean very cheap renewable electricity, by which point there's no need because electric cars are more direct replacement. but there are applications where hydrogen is used directly, as a reagent instead of as energy source and can be made from renewable electricity. Yara makes some of fertilizer this way and there's a pilot plant for green steelmaking in sweden iirc. it just so happens that now cheapest hydrogen is made from gas

this also pulls in different directions because people building renewable generation don't want electricity price to be too low

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
