Why are you still posting, and not withdrawing Scholmz's money? He posted video evidence of what you are looking for, that wrecks your theory. Get to the bank.
Video evidence! Of what? You have to describe the structure A you intend to one-way crush-down. Then you have to build it, disconnect top C and drop C on A and one-way crush-down A by gravity and by C. And report. See rules at http://heiwaco.tripod.com/chall.htm . Scholmz must follow the rules. Not just copy/paste a video of controlled demolition of an old house using external energy, etc.
According NIST, Bazant and other terrorists it is possible and simple to crush a structure only by gravity. Any structure will do. And, actually you don't have to drop C on A! Just fly a plane into top of A and after a while A is one-way crushed-down.
So just do it! I have asked Bazant several times to produce a structure and ... no reply! Does he exist?
Imagine: dropping a little piece C of the complete Earth A on the Earth and pouff - Earth is crushed. Gone. Pouff, pouff! http://heiwaco.tripod.com/pouf.htm . According Bazant anything goes pouff, pouff. Just drop it.
Crazy, isn't it? And GWB and Condoleezza believe these clowns. That is of course logical! GWB isn't very intelligent and Condi is just an ice skater that can play piano.
