It is strange but perhaps this is referring to a ratio. A temperature change similarly does not imply any energy delta (in classical physics at least) as the mass of an object approaches zero. I agree though, just tell us how much more efficient it is than existing technology. >> Low voltage with extremely high current is still a lot of energy To be a bit pedantic, this is strictly a lot of power - it is necessary to multiply by time to get energy. 1 amp * 1 volt = 1 watt = 1 joule / second
