Made this mistake once. Searched for Electroneum but spelled it Electronium. To my surprise I discovered Electronium was invention by Raymond Scott. He was an engineer and musician that invented this system that is the predecessor of the modern day synthesizer keyboards you hear in just about all of today's music. The only one ever produced was commissioned by Barry Gordy at Motown Records. Scott built the thing, but it was never totally completed. It cost close to a million dollars. Well, I can afford to invest in Electroneum but not Electronium.
