I'm still waiting for the sound deadening paint that will also power my home by absorbing ambient vibrations.

  Piezoelectric energy harvesting is cool though, even if the paint stuff is a pipe dream

  We're awash in waste energy (thermal etc.), but almost every form of harvesting it is way more expensive $/watt than tapping the grid.

    Yep, the second law of thermodynamics is like that.

    The $/watt price from tapping the grid part might solve itself in the foreseable future. Not that I'm happy with it.
