Biefeld-Brown Effect
TL;DR
Let’s breakdown the Biefeld-Brown effect and analyze what the different contributing factors are to producing, and most importantly, maximizing the effect for real world propulsion.
There are many factors that together combine to create the Biefeld-Brown effect, the propulsive force observed in the direction from lower voltage to higher voltage plate in an asymmetric parallel plate capacitor. It is my hypothesis that the biggest factor behind the Biefeld-Brown effect is the production of spin alignment of unpaired protons in the dielectric and the metal capacitor plate electrodes.
Introduction
To put it simply, inertia is the force you feel pushing you into your seat when you are accelerating in a car and the same force you feel when slamming on the brakes. It is the force every object feels when it is accelerating or decelerating. Albert Einstein posited that a man standing in a rocket that was accelerating vertically at 9.8m/s2 would be unable to tell the difference between standing in that accelerating rocket and standing on the planet Earth whose gravitational acceleration rate is also 9.8m/s2. Formally this correlation is known as the Equivalence Principle.
One interesting fact about the Equivalence Principle is that an object's inertial and gravitational masses are believed to be equal which results in objects of different masses falling at the same rate. This was demonstrated in the Apollo 15 Moon landing in 1971 where astronaut David Scott dropped a hammer and a feather at the same time. The reason feathers fall slower on Earth is due to wind resistance. On the Moon there is no atmosphere and therefore no wind resistance.
