Don\'t. The one thing we can be confident of is that a little coil won\'t stand off 400kV.

https://citeseerx.ist.psu.edu/document?repid=rep1&type=pdf&doi=6b3e32e68678a4afa7b62deef22d383e80c9880a

A 15mm gap in 5 atmospheres of SF6 will only stand off about 120kV. For 400kV you\'d need 50 mm. That\'s not a small coil.

Transformer oil does better - you only need 10mm to just stand off 400kV.

Of course you\'d need a lot of inductance to keep the current from saturating the core and you can\'t use a multilayer winding to get lots of turns.

So you need a big core and have to bank wind it, as well as sinking it in transformer oil.

The windings will have a lot of capacitance so you wont be able to switch them fast , which means that you will need even more inductance to stop the core saturatiing

Mindless experimentation isn\'t going to get you anywhere.

Don\'t you just need a kite and a battery big enough to store the energy
from the lightening strike? Power for life.

There might be an impedance mismatch charging the battery.

I\'ve never heard that term applied to DC and don\'t know what you mean. I only understand it for audio amplifiers.

The Maximum Power Transfer theorem works for AC or DC.

It makes sense for an amp, but not for raw power. For example, there\'s 240V at that socket there, with virtually no resistance. If I connect a resistive heater to it to it to draw power, I get all the power as usable heat pretty much, even though the resistance of the heating element is vastly more than the supply. What if I connected a fucking big element to it, such that it\'s resistance was equal to the supply line? Half the power would be dissipated in the supply line. I\'d drop from 99.9% to 50% efficiency.

Yes, that\'s one implication of the theorem. You could really conjugate
match your AC line for a cycle or two and get a lot of power before
the breaker trips.

What is a breaker? Is that a modern version of a fuse?

Yes, that\'s right.


People don\'t impedance match audio amps either.

I\'m sure I was told you do to get the most power out. I guess that\'s only true for rubbish amps with a high resistance, where connected low ohm speakers to it gets less power out by dropping the voltage. IF you impedance matched a milliohm amp, you\'d get more current than it was capable of producing and break it.

If you impedance match any amp the efficiency will be below 50%.

It the impedances are the same, half the power is in the load, this is the best case scenario, and why it says on the back of the amp \"use 8 ohm speakers\". If the speakers are a lower impedance, most of the power is heat in the amp. If the speakers are higher impedance, you\'re dropping the current.

\"Damping factor\" is
one of those quaint terms that audiodudes use to express the mismatch.
A good power amp has milliohms of output impedance.

A \"600 ohm\" audio output is usually much less.

RF types use \'S11\' and \'S22\' to express matching. A horrible mismatch
sounds better expressed in dB.

My NMR gradient amps were very good current sources, which is why they
worked better than hacked audio amps.

There is a battery that consists of a beta emitter coated rod inside a
metal tube. It develops hundreds of kilovolts at low current, and the
problem has always been, aside from the radioactive hazard, how to
convert that down to something useful.

Can\'t be that hard, we convert voltages all the time.

Please sketch up a 5 volt power supply with a 400KV input.

Just take a normal one but moreso. Do you really think it\'s much harder to convert 50V to 5V than 10V to 5V?

Yes, fewer switcher chips are available at 50 volts. I\'m doing a bunch

weird.

Most audio amplifier are designed not to break. Typically they are designed to source enough current to drive an 8 ohm speaker. If you use one to drive a 4 ohm speaker, you will likely get only half the voltage swing. The crudest protection would blow a fuse if you try to get more voltage swing because that would make it try to deliver more current than the output devices were capable of supplying. More subtle protection tends to sound horrible when the amplifier goes into current limit.

If you impedance match any amp the efficiency will be below 50%.

Wrong.

If the speakers are a lower impedance, most of the power is heat in the amp. If the speakers are higher impedance, you\'re dropping the current.

\"Damping factor\" is one of those quaint terms that audiodudes use to express the mismatch.

It isn\'t.

And so is John Larkin.

The most practical solution I could come up it to suspend magnet on a needle bearing in a sealed (and largely evacuated) chamber and use the 400kV source to create an electric wind to rotate the magnet. Put figure of eight coil outside the chamber under the magnet, and rectify the AC current induced in the coil.

It would be a pathetic power source, but it is practicable.

I have a rain radar. Stand in the middle of the garden, rotate, observe clouds.

May work if little wind, we have 5 Bft here now, so one hour may make a lot of difference as rain clouds
come in that you did not see. Just after you got all the garden tools out...

It doesn\'t take an hour to get tools out.

I also use rain radar if I want to go biking.

Isn\'t your skin waterproof?

Yes, but electric grass mower, electric hedge cutter, electric weed burner
very long extention cables, 230 V 50 Hz AC here,

If you have a sissy circuit breaker, what are you worried about? If you have fuses you\'re not a sissy anyway.

Wet environments provides a ground path.
Do not use electric tools in the rain.

I\'ve used a mower in the rain twice. Made me jump and swear, but that\'s all. Fucking pathetic girl.

Leaving the tools out in the rain is even more stupid, it will damage things, and electrocute you if you handle it.
Basic rule:
Make sure there never is a ground path.

Rules are for the obedience of fools.

I have learned to avoid using it in rain, and want to keep it in one piece too.

Motors are only harmed by salt water.

Bull

!

Try your cordless (since you\'re too scared to use a mains one) drill in water. It will work fine.

Raindrops falling on piezo transducers could work too?
Or falling on a horizontally mounted dynamic speaker cone ?

I will take a closer look perhaps when their thing is in the shops here.

The speaker cone could become a large microphone, and you could feed the data into a complex system for weather
prediction.
You
would know immediately when it was raining, without the hassle of looking out the window.

I you used a 1 to 10 standard audio transformer in reverse perhaps there would
be enough voltage to flash a LED if a drop hits the cone.

All that said I just look at the \'rain radar\' here, this morning showed the last shower of today leaving
and I started work in the garden...

Grass involves a lot of annoying labor, and you can\'t even eat it.

OK, but it is good to get out and get some excercise.
You can it on it in summer in the sun with some nice food.
Have some nice garden chairs too.

The traditional method aggregates the raindrops in a dam and drives a turbine. Commonly called hydroelectric generation.

Ice baths are very good for you and zero effort.
