The Karpen electrochemical cells
Nicolae Vasilescu-Karpen
The idea
Vasilescu-Karpen constructed electrochemical cells with gold and platinum electrodes, preserved in Bucharest’s technical museum.
A small experimental cell became a lasting museum object. The national museum catalogue identifies Karpen’s gold-and-platinum electrode cells among its holdings. Their historical interest does not establish perpetual motion or unlimited free energy.
