Juan J. Tomadelli

Juan Joseph Tomadelli (August 19, 1885 - November 1962) was an Italian-born American socialite, painter, and electrical engineer who promoted a cold self-sustaining incandescent light bulb, referred to as "Bottled Sunshine," which he claimed would remain lit for up to three years without electrical current, drawing power from the atmosphere. Tomadelli ultimately failed to produce his technology and was charged repeatedly with fraud in connection with the claims, including an attempted enjoinment against selling stock by New York in 1924 (dismissed due to lack of evidence that Tomadelli made representations that were "consciously false and made with intent to deceive"), an injunction against selling stock by New Jersey in 1928, and a conviction in 1942 on federal mail fraud charges.
