Karpen's Pile: A Battery That Produces Energy Continuously Since 1950 Exists in Romanian Museum.: "The 'Dimitrie Leonida' National Technical Museum from Romania hosts a weird kind of battery. Built by Vasile Karpen, the pile has been working uninterrupted for 60 years. 'I admit it's also hard for me to advance the idea of an overunity generator without sounding ridiculous, even if the object exists,' says Nicolae Diaconescu, engineer and director of the museum."
