  1. MACH 1 is 1/3 km per second = 6 times slower than 2km/s. Kinetic energy is mass*speed*speed*0.5 So if demonstrator speed is 1unit of speed then its kinetic energy is 0.5units of kinetic energy and with speed of 6units(2km/s) the kinetic energy will be 18 units so the demonstrator is doing less than 3% of the kinetic energy... MACH 1 is the limit for most helicopter rotors tips as you do not want to have part of the rotor blade going supersonic and part of it subsonic. The whole demonstrator looks like a scam for people that have money but do not want to do the math...
