not to be taken serious?Fun fact:in 1989 two electrochemists actually claimed to have created a small electrolysis device using heavy water with deuterium and a palladium electrodeDue to the PR shitstorm that followed when everyone and their goat tried to replicate the result and failed, then the two guys' claim was dismissed and cold fusion never given that much attentionbut experiments continue.And the results aren't that bad. The deuterium in the water is attracted via the electric current running through the water to a paladium/tungsten/platinum electrode, which suchs the deuterium into the electrode at a molecular level. This results in a compression so hard that the individual deuterium molecules fuse to the electrode. Fusion.the main issue now seems to make it a stable reaction - to somehow ensure that you get a stable excess of heat out of the process.TlR - the makers of the iron man movie arc reactor probably knew about this... but didn't wanna call the thing a miniaturized cold fusion reactor
