Hi, does anyone have suggestions for small scale power transmission over 1 wire, with no ground?
Imagine a small helium balloon, tethered to ground using a fine single conductor. The balloon has camera and other sensors and needs a few mA average. Probably under 10mA at 3.3v (33mW).
Obviously the goal is to have the balloon electronics powered over the tether conductor, and have it permanently aloft.
So the receiving power converter needs to be both small and light.
The ground based power transmitter can be larger and does not need to be efficient.
Any suggestions will be much appreciated.
