It was a long time ago, I was called into help shore up the lower bridge from falling further. It was sureal. after a few days the spell of rotting flesh was overwelming. I went 5 days without sleep on adrenline ( or the fear that i would be crushed ) anyway sometimes i still see clips of me...

My thought are if we can make sound crumble concrete we can use this device to rescue people in a a colapsed building. without heavy equipment.

Would it be possible to break concrete into rubble with sound? if so, How much energy would it take? Forgive me if this is a stupid question, I am not a physics guy but am trying to learn. Joe
