Subject: Can someone explain Eric Laithwaites Royal Institute lecture?

I searched internet for valid explanation of Eric Laithwaites Royal Institute 
gyroscope demonstration.

Yet, I still haven't found a satisfying answer as to why an old man could lift 
a 50lb gyro so easily.

There must be an applications for this - at a basic level, consider moving 
cargo?

If Mr Laithwaite could lift the gyroscope, what would happen if spun faster? 

I dont imagine that this is a perpetual motion machine. However it seems there 
are questions surrounding gyroscopes - that nobody answers and some ignore.
