What is electromagnetic drive?

The so-called EM drive – a rocket engine powered by electromagnetic waves – has been touted as a way to eliminate fuel required for deep space exploration. The idea is championed by inventor Roger Shawyer, whose EM drive uses microwaves trapped in a conical cavity to generate thrust.

How does an electromagnetic drive work?

The RF resonant cavity thruster (or EM drive) was first proposed in 2001 and is essentially a propellant free propulsion system. It works by firing microwaves into a closed truncated cone, which push on the cone and propel the craft forward. … Because there’s no reaction in the same way as conventional propulsion.

Is an electromagnetic drive possible?

After failing critical thrust tests, the “impossible” engine has proven to be just that. The “impossible” EmDrive has failed international testing in three new papers. The idea was always far out, but that’s part of how science moves forward.

Is Reactionless drive possible?

Physicist: In a word: no. A reactionless drive is basically a closed box with the ability to just start moving, on its own, without touching or exuding anything.

Who made the EmDrive?

In his presentation to the April 3 meeting of the biweekly Alternate Propulsion Engineering Conference (APEC), Roger Shawyer, who developed the EmDrive back in 1998, detailed different tests over time of all three generations of his concept.

Is NASA working on warp drive?

NASA is obviously still working out the kinks of their warp drive, but perhaps it’s only a matter of time before at least neighboring star systems, like Proxima Centauri, will be in reach for human crews. Until then, we can only look at the furthest stars using our telescopes.

Has the EmDrive been debunked?

In March 2021, physicists at the Dresden University of Technology published three papers claiming that all results showing thrust were false positives, explained by outside forces: When power flows into the EmDrive, the engine warms up. … Our measurements refute all EmDrive claims by at least 3 orders of magnitude.

Is magnetic propulsion real?

The present state of modern technology allows the use of magnetic propulsion systems as orbital microthrusters in the near-to-earth space. The current thrust-to mass ratios of these systems are relatively low. Nevertheless, since they do not require propulsive mass, the vehicle mass is constant.

Can magnets bend gravity?

Electric charges and magnets do indeed “distort space,” but this happens on a couple of levels. … According to the current best theory of gravitation, which is contained in Albert Einstein’s famous general theory of relativity, a gravitational field represents a curvature of space-time, rather than a distortion of it.

Is Quantum drive possible?

Although this concept may be allowed by the currently accepted laws of physics, it remains unproven; implementation would require a negative energy density, and possibly a better understanding of quantum gravity.

What is Quantum drive?

A quantum drive is a type of engine that generates a Chan-Eisen field, enabling spacecraft to travel at approximately 20% of the speed of light.

Is warp drive faster than light?

A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude. … In contrast to hyperspace, spacecraft at warp velocity would continue to interact with objects in “normal space”.

What is anti gravity technology?

“Anti-gravity” is often used to refer to devices that look as if they reverse gravity even though they operate through other means, such as lifters, which fly in the air by moving air with electromagnetic fields.

How fast can an EmDrive go?

EmDrive: NASA Engineer Says Physics-defying Engine Could Go 99% the Speed of Light.

Are solar sails real?

Since the failed Cosmos 1 mission, solar sails have been successfully built and launched by the Japanese Aerospace Exploration Agency (JAXA) with their IKAROS spacecraft that first demonstrated controlled solar sailing, by NASA with their NanoSail-D spacecraft, and by The Planetary Society with our LightSail 1 …

How fast is nuclear pulse propulsion?

velocity of 13,411 km/s, at a distance of 4.5 light years, equivalent to 4.5% of light speed).
