This is the Holy Grail of space travel.
EmDrive, also known as a quantum vacuum plasma thruster, doesn’t need any fuel in order to operate. Without a fuel, what could create energy necessary to overcome gravity and reach orbital velocity? This is totally contradictory to applicable laws of physics, most notably, the Conservation of Momentum, implied in the Newton’s laws of motion, a cornerstones of modern physics.
EmDrive technology, a brainchild of Roger Sawyer, who has been ridiculed by the scientific community as a “TV repair man”, is based on microwaves bouncing around a specially designed container inside which the difference in radiation pressure creates thrust. It directly converts electrical energy (from solar panels) to thrust. EmDrive was developed by Satellite Propulsion Research Ltd, a UK startup company.
Last year, Eagleworks Laboratories in Huston, Texas, led by Dr. Harold White, presented a paper at a conference in Cleveland, Ohio, which describes experimental tests they conducted on a this concept of a space engine that has a potential to take us to Mars in a couple of weeks, and to nearest stars in little more than a century. Such a venture with the available propulsion technology, based on liquid propellants and nuclear reactors, would otherwise be impossible. It would take us thousand s of years to reach the nearest star, Alpha Centauri, which is located some 4.3 light years from our solar system. Not to mention all the logistics problems implied in similar attempts.
Previously we have written about similar tests conducted on EmDrive propulsion that’s been an object of controversy among scientists for many years. Its patented microwave technology was tested by four independent research teams from three different countries, which confirmed unexplainable thrust. Although these findings were refuted by most scientists on the basis of tiny effects which could easily be interpreted as noise or measuring error, the trials continued.
The new tests, conducted at NASA’s Johnson Space center, were performed in vacuum, in order to dismiss the interpretations according to which the measured output was a result of thermal convection produced by microwave heating, or other environmental conditions external to the engine. These new findings were recently reported in NASASpaceFlight.com’s forum by Paul March, NASA Eagleworks engineer, and the tests were successful, again. EmDrive works.
These new test results spurred a huge interest of enthusiasts from around the world, who are now discussing possible application of EmDrive propulsion in current and future space missions on NASASpaceFlight.com EmDrive forum.
