Resonnant circuits in cascade.

And - on the subject of Tesla... yes he was using power.  I did not leave that out in my description of his experiment... so I do not know what your point was...

But here's another lesson from Tesla.  With his coil - he produced a cold electricity that he could step up 10,000 times per foot of his coil.
This is the same cold electricity produced with tesla coils anyone can build... and you can touch it without being shocked... and YET - a plate of sheet metal in the field of this coil will have a current induced in it that will light an incandescent bulb.

When your EE book can explain that - then you talk to me.    Otherwise... I suggest that you do not know everything.

When I was a broadcast engineer, an old-timer showed me a really cool trick.  He walked over to the base of the antenna tower of a 10 KW AM station, and, holding a regular lead penciil in his hand, drew a three inch arc from the tower to the tip of his pencil.  The graphite tip of his pencil soon became red hot, and after four or five seconds, he withdrew the pencil - its tip still smoking.  He handed me the pencil so I could repeat the same stunt.  The body of the pencil - and my hand - became only slightly warm from the RF.

Electricity is electricity, and is neither cold nor hot.  Electricity does have volts, current and frequency, and certain combinations thereof behave in ways that are startling if you've never experienced them before.

I've built probably a dozen tesla coils - including one that was 12 feet tall, wound with Litz wire, and fed from a 16 kW transmitter.  It ended up heating the rebar in the concrete floor so hot the soles of my shoes melted.  I've also worked on multi-megawatt shortwave transmitters.  The trick there is to KEEP them from becoming tesla coils.  There is nothing I've ever seen in my hobbyist tesla coil experiments that I haven't also seen in a high power shortwave transmitter - in a much bigger way.

  I've seen voltage on a 100' loop of 40v... and you feel it when you touch it.
Call it what you like... that is power.

No, that IS my point! Voltage is NOT power.  If you terminate this 100' loop with, say, a 50 ohm resistor, then you can correlate voltage and power, but not until then.

[Elvis Oswald]

Voltage is not power.  The 40v is just voltage.  But I contend that if it shocks you, then it is voltage moving current - right?

So now we are only talking about the amount of power you can pull out of such a large wave of either 12Hz or 7.43Hz.

Apparently Tesla was able to do it with a couple of metal rods and a dozen tubes and some wire in 1931.  He powered a 80hp A/C motor in a Pierce-Arrow for a week.

So this is what we are talking about replicating.  Perhaps LC circuits are not the way to go... but that is what experiments are for.
