John Hutchison used directed Millimeter Microwave energy to generate novel effects that include:

Propulsion

Negation of Gravity

Molecular Phase Transition

It is molecular phase transition which brought down the Twin Towers. Like turning the bones of your spine from a solid to a powder.

The Molecular Phase Transition effects requires more than one focused beam of millimeter microwaves to transit through an electro-static field, think Tesla Coil/Van de Graff Generator/Hurricane. The MMMW beams must overlap. Whatever resides within the overlapping zone of the two MMMW Beams will experience the molecular phase transition, changing the molecular material from a solid to a powder.

The Propulsive effects requires a singular MMMW beam to transit through an electro-static field, Tesla coil/Van de Graff Generator. Think Bob Lazar UFO, which used MMMW emitters housed in a wave guide, which could be directed through an electro-static field that adhered to a metalic skinned structure, generating propulsion.

The foundations of the Bob Lazar's craft were set down by James Clerk Maxwell in the 1860's-70's.

Maxwell's equations are a set of partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits. The equations provide a mathematical model for electric, optical and radio technologies, such as power generation, electric motors, wireless communication, lenses, radar etc. Maxwell's equations describe how electric and magnetic fields are generated by charges, currents, and changes of the fields.

Millimeter Microwave Energy is a tool which can be used for good or harm. The purpose for which the tool is used depends on the intentions of the ones using said tool.

When 5G routers become ubiquitous that will give me the opportunity to build my own UFO. :D
