This video claims that the transmitter is self powered and hence needs no battery or other electric connection.
Is this possible? I have never come across an electronic device that runs self-powered.
Couple of things I think might happen here:
1. A solar cell in the transmitter?
2. Everytime when someone presses the switch, it converts some of that energy to electricity? Like piezoelectric for instance?
