Yes, I am a structural engineer and registered PE.

How do explain THREE collapses at near free fall speed? First time in
history from fire!

It is called progressive collapse. This is when a smaller less
significant failure causes an overall greater failure.

Where did the energy come from to pulvarize concrete and office furniture
into particles of fine powder?

The concrete and other materials had a large amounts of potential
energy stored when they were raised to a higher elevation in the
building. BTW, you don't need to be an engineer to know this, you
need to have not slept through 6th grade science class.

Where did the force come to *evaporate* steel?

Steel doesn't evaporate. ASCE (an independent non-government
organization) determined from analysis that "The thinning of the steel
occurred by a high temperature corrosion due to a combination of
oxidation and sulfidation.

Why was there moltel metal and yellow-hot metal under the Towers (AND
BUILDING 7) weeks after 9/11? (Those colors are consistant with thermite
explosives.)

Fire. BTW it can be consistant with many things.

Also, why did the government hall away and destroy the evidence before it
could be properly analyzed?

See above about ASCE analyzing the steel.
