No I have not gone completely insane, nor it is a belated April fool's joke. Apparently Sugizo tested Toyota's Mirai and Honda's Clarity Fuel Cell as alternative energy sources to power his guitar system and he will experiment with it further, saying that he heard subtle differences in sound quality versus normal electricity supply.

edit: they will use this system at Luna Sea's 5/29 show at Budokan.
