Open Thread – Eel-Powered Christmas!
This was taken at a Christmas display in the ‘Journey To South America’ gallery at the Living Planet Aquarium in Sandy, Utah. The blinking is caused by using the energy generated by an electric eel in a nearby tank. “We took the voltage produced by the eel via stainless steel electrodes and used it to power a sequencer,” said Terry Smith, Project Manager at Cache Valley Electric. “The sequencer takes the voltage the eel produces and operates circuitry that flashes the lights, fast or slow, based on the level of voltage he puts out, ” said Smith. Each time the eel moves, the lights on the 5ft tall tree flash intermittently using 4 strands of holiday lights.
