When you land on that alien planet, and escape your abductors, then you need to IMPROVISE.

You got it man!
I was sinking baut this, it seems if yer mama has an induction cooking machine, and you an eepod or something, then as every electronics minded lifeform always carries some diodes, and some capacitors, and a magnet of course to activate the iron detector in that cook er then you can charge your pod and send a message to yer planet .
NASA can detect an eepod on one of our planets I'm sure.

Remember how the voltage was regulated in the Cray-1 CPU? A variable speed motor driving a generator.

Right, nothing says low noise like pulling power from a big energized open air inductor.

In the old film audio synchronisation (voice over) studio where I worked the 'magnetocord' (= perfo-tape, audio tape with holes in it like film), moters were together with the film projectors run from a DC to 50 Hz net generated by a field coil from a motor / generator combination that was slowly stopped.. To keep the audio in sync you know. There were more relais in that building than people that is for sure..

There is an exponential curve .. Anyways, I was wearing a radio watch, quite expensive, it can sync to that long wave radio transmitter in Germany. Was a bit worried if it still worked. It does. Has this little ferrite rod tuned to DCF77

DCF77 is at 77.5 kHz, this heater operates as about 100 kHz (lower on heavy load). Watch seems to have good selectivity, good design Casio!
Although DCF77 transmits at 50 kW it does not really interfere with a lot of things...
I am using google ;-)
