    Jun 29 2012: About energy :

    We produce high voltage electricity, not because we need it, but to be able to transport it.
    Nearly all of our devices use 12V and must use a transformer tu use 110V or 220V.
    A family boat or a camping car use a 12V battery.

    99% or our energy "need" is a waste : it is used to make the whole energetic system possible = Pure tautology.

    We work to sustain the work. That's nonsens. (or maybe I'm an idiot?)
