The EmDrive

The EmDrive is a reactionless spacecraft drive proposed by and its inventor Roger Shawyer in 1999. It has become one of a small family of supposed reactionless drives, and each researcher seems to have their own pet theory. Shawyer's "theory" is based on special relativity, at least as Shawyer understands it: he claims that the radiation inside the cavity has less momentum at the narrow end of the cavity due to a reduction in group velocity and that the resulting force against the large end is higher.Forces exerted on the sloped sides of the resonant cavity are dismissed as "negligible", when a simple application of conservation laws would have them exactly equal any change in momentum of the electromagnetic wave travelling along the cavity due to the geometry of those surfaces. Shawyer's theory is muddled and inconsistent, with misunderstandings of the equivalence principle and an apparent assumption of an absolute universal rest frame (he and Dr Harold White claim the device loses efficiency as it accelerates, and Shawyer claims that the drive is best used to hover instead of accelerating, despite there being no difference between hovering and accelerating at 9.8 m/s2), and many other problems. Amusingly, he not only seems to believe there is an absolute rest frame, he apparently believes that Earth's surface is at rest with respect to it.

The Chinese researchers suggest it's somehow based on electromagnetism and Maxwell's Law, and Dr White's group believes the microwaves push against "quantum vacuum virtual particles" in the resonant cavity. Dr Fernando Minotti, a researcher at CONICET, in a 2013 paper titled "Scalar-tensor theories and asymmetric resonant cavities" noted that the alleged thrust produced by the Emdrive may be explained by certain scalar-tensor theories of gravity. Also, Dr Michael McCulloch in a paper titled "Can the Emdrive Be Explained by Quantised Inertia?" Noted that the thrust produced by the EmDrive may be explained by Unruh radiation which causes the photons in the wide end of the cavity to have greater inertial mass than the photons in the narrow end, causing the cavity to exhibit thrust towards the narrow end. Several prominent physicists have said that the concept is impossible. A PhD physicist, John Costella, in his related paper explained why.

The Nassikas Thruster

Basically, the thruster is propelled by unbalanced forces due to the effect of the magnetic field on the nozzle.  Superconductors expel magnetic field lines and as a result, an external magnetic field source will exert a force on the superconductor, the so-called Meisner effect.  The field lines are more concentrated within the throat of the nozzle which pushes the nozzle in the convergence direction, whereas the field lines impacting the outer surface of the nozzle and pushing in the opposite direction are much weaker.  The net effect is that the nozzle has a net propulsion force.

<< Maglev trains levitate on the basis of the Meisner effect.  In maglev, the magnet is attached to the ground and levitates the superconductor.  In the Nassikas thruster, the magnet is attached to the superconductor and propels itself and the superconductor together.  Of course, this throws Newton’s third law and the law of energy conservation out the window. " For more information about the Nassikas Truster please use this link:

Rocket Engine

A rocket engine, or simply "rocket", is a jet engine[1] that uses only stored propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law. Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as terrestrial uses, such as missiles. Most rocket engines are internal combustion engines, although non-combusting forms also exist.

Devising yet another ingenious way for people to accidentally kill themselves (or as the British euphemistically call it "death by misadventure"-damn you, British, and your clever way with words!), Trek Aerospace is working on a line of personal Vertical Takeoff and Landing (VTOL) aircraft, including the Dragonfly UMR-1, and our personal fave, the Springtail EFV-4A (pictured above). Let's just hope they can build one that goes more than 18 inches off the ground.

Space Elevator

A space elevator space transportation system. The main component would be a cable anchored to the surface and extending into space. The design would permit vehicles to travel along the cable from a planetary surface, such as the Earth's, directly into space or orbit, without the use of large rockets. An Earth-based space elevator would consist of a cable with one end attached to the surface near the equator and the other end in space beyond geostationary orbit (35,800 km altitude). The competing forces of gravity, which is stronger at the lower end, and the outward/upward centrifugal force, which is stronger at the upper end, would result in the cable being held up, under tension, and stationary over a single position on Earth. (The Patent documents for Space Elevator is in "Related Patents-Page")  

MC-130J Commando II and CV-22 Osprey tilt-rotor aircraft

MC-130J Commando II and CV-22 Osprey tilt-rotor aircraft The introduction to service of the CV-22 at RAF Mildenhall resurrects a vertical lift capability not seen here since the retirement of the MH-53 Pave Low helicopter. The CV- 22 has the capability to take off, hover and land vertically when required but also the speed and agility of a conventional turboprop aircraft in forward flight enabling it to operate over greater distances compared to a helicopter.

MAGLEV trains

Eric Roberts Laithwaite (14 June 1921 – 27 November 1997) was a British electrical engineer, known as the "Father of Maglev" for his development of the linear induction motor and maglev rail system.


We have always thought of airplanes as the fastest mode of transportation. As it travels thousands of miles in an hour we do not mind the flight delays and also the risk in flying. There is no other alternative to planes that can travel such a great distance in a minimum amount of time. Buses, cars, boats and even conventional trains seem to be too slow in comparison to planes. Now a new transportation mode has occurred that can clearly compete with planes in both speed and safety. 

They are called MAGLEV trains. The full form and the basic working principle of MAGLEV are called Magnetic Levitation. The principle of magnetic levitation is that a vehicle can be suspended and propelled on a guidance track made with magnets. The vehicle on top of the track may be propelled with the help of a linear induction motor. Although the vehicle does not use steel wheels on a steel rail they are still referred to as trains as by definition they are a long chain of vehicles which travel in the same direction. This is the definition of a MAGLEV Train(The Patent documents for "Magnetic Levitation" is in "Related Patents-Page")

Dean Drive


The Dean drive was a device created and promoted by inventor Norman Lorimer Dean (1902–1972) that he claimed to be a reactionless drive. Dean claimed that his device was able to generate a uni-directional force in free space, in violation of Newton's third law of motion from classical physics. His claims generated notoriety because, if true, such a device would have had enormous applications, completely changing human transport, engineering, space travel and more. Dean made several controlled private demonstrations of a number of different devices; however, no working models were ever demonstrated publicly or subjected to independent analysis and Dean never presented any rigorous theoretical basis for their operation. Analysts conclude that the motion seen in Dean's device demonstrations was likely reliant on asymmetrical frictional resistance between the device and the surface on which the device was set ("stick and slip"), resulting in the device moving in one direction when in operation, driven by the vibrations of the apparatus.
