Interesting.
Then I suppose a broadband RF detector can be made by aligning a tube of brine towards a source. Alternatively a 3D microphone array could be employed in an ocean.
External noise floor probably sets the maximum sensitivity, but should be possible to process most external noise out
- baerrie 3y agoHow does the brine help detect the RF?
- seamac3 3y agoElectrolytes? Better conduction of EMF? Just a guess.
- jacknobody 3y agoIn fact a silly idea I had
- baerrie 3y agoThere are no silly ideas!
- jacknobody 3y agoThank you :)
- jacknobody 3y agoThere the piece suggests that KCl conduction is sufficient to enable the electric- acoustic effect, and brine is sea water, which also conducts. So maybe a matrix of sensitive microphones in the sea can detect the direction of a radio signal.
