Umm. No. If you look at a collision where momentum transfer occurs, the moving object will decrease in velocity. Unfortunately for Mr. Szamboti, his entire idea is based upon a really bad assumption: that the upper and lower blocks are both rigid bodies and free-to-move. Momentum transfer between the upper and lower block does not occur as the lower block is not free to move: it's attached to the Earth.
More importantly, if one considers that the upper and lower block will both behave as springs, the "jolt" that Mr. Szamboti is looking for at the roof-line can never occur. The force exerted from the lower block to the upper block will cause the a "jolt" in the bottom most portion of the upper block, this is true. However this jolt is going to be damped out at the roof-line as the columns in the upper block compress. It will behave quite similarly to shock absorbers on a car.
His entire thesis is based on assumptions that does not reflect reality. Though the assumption is wrong, his understanding of physics and engineering AFTER said assumptions are made is mostly correct.
