Thames Water Radio

I created a radio receiver that used River Thames estuary water as an antenna for a piece of audio artwork by Cathy Fitzgerald. The receiver used a pump to fire the water up into a perspex tube. The salt from the brackish water meant radiowaves caused induction in the plumb of water, which could be demodulated and played out of loudspeakers. The signals were transmitted by a Raspberry Pi mounted in the tower of the lightship LV21.
