Re: Electric planes do get lighter...
I am not a nuclear physicist, but as I recall, in the case of a battery, you're not converting matter into energy. That only happens in things like nuclear reactors. You're converting one form of matter into another (lead and sulfuric acid into some other mix of those elements that I can't remember offhand) and one form of energy (chemical potential) into another (electricity).
If you cause the battery to outgass, that could "make the plane lighter" in that some of the mass would not be carried by the aircraft, but in terms of the total system, the overall mass remains the same.
or did I miss an irony/joke icon?
