"Nuclear-Powered Vacuum Cleaners Will Be a Reality in 10 Years" — Alex Lewyt (1955)

Alex Lewyt's 1955 promise of nuclear-powered vacuum cleaners within a decade epitomizes atomic-age overreach, being far more extreme than the typical optimistic prediction about consumer nuclear energy. The Lewyt president's vision anticipated a future where homes hummed with mini-reactors, yet today zero commercial nuclear appliances exist. Instead, the total U.S. nuclear capacity stands at 96 gigawatts from 93 large reactors—a 10,000x scale difference that highlights how his 10-year timeline failed by an order of magnitude compared to the actual path of nuclear adoption.
