How to define "Electrical"?
hah posted for all of us...
So you have a radio that works with no electricity. How does that work?
Considering that radio signals themselves are electric fields, you'd
need a new kind of broadcasting.
You don't need electricity to receive AM. A (?)crystal will convert the
received signal to headphones. DAGS on Crystal radios.
