How Does An Electromagnetic Drive Work?
How does an electromagnetic drive work? But the EM Drive works without any fuel or propellants at all. It works by simply bouncing microwave photons back and forth inside a cone-shaped closed metal cavity. That motion causes the 'pointy end' of the EM Drive to generate thrust, and propel the drive in the opposite direction.
What is EmDrive supposed to do?
EmDrive is a concept for a radio frequency (RF) resonant cavity thruster that is claimed to have potential applications as a spacecraft thruster. It is purported to generate thrust by reflecting microwaves internally in the device, in violation of the law of conservation of momentum and other laws of physics.
How fast would an EmDrive go?
EmDrive: NASA Engineer Says Physics-defying Engine Could Go 99% the Speed of Light.
What is an 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.
Is NASA working on a 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.

What happened to EmDrive?
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 there a working EmDrive?
The inventor of the physics-defying EmDrive defended his controversial propulsion device. Roger Shawyer, who created the EmDrive in 1998, said competing researchers got the whole design wrong, leading to recent failed tests. Shawyer is currently working on the third-generation EmDrive design.
Does the EmDrive really work?
Side stepping that Earth shattering possibility, the EM Drive, through rigorous peer review does indeed work. Not only does it work but because it doesn't require fuel it's lighter, cheaper, safer and far more efficient than current space rockets. It also doesn't explode. It's also fast.
Does the EmDrive work in salvation?
Last night (July 19) in the fictional television show "Salvation" on CBS, where an asteroid is on its way to slam into the Earth in six months, engineers talked about the EmDrive — an experimental engine that is supposed to break the laws of physics. While the plot is fully fictional, the EmDrive is not.
Who invented EmDrive?
How long would it take to get to Mars with an EmDrive?
All in all, your trip to Mars would take about 21 months: 9 months to get there, 3 months there, and 9 months to get back. With our current rocket technology, there is no way around this. The long duration of trip has several implications.
What happens if a space ship runs out of fuel?
Even when the thrust that comes from the fuel runs out, the space ship will still move forward thanks to the momentum that came from the fuel. This momentum will then carry the space ship forward on the same trajectory that it was already travelling, even when the fuel runs out and the engine shuts off.
Can Rockets work in a vacuum?
There's no air for the engine to burn in space! And there's no air for the rocket to push against in space! In spite of what they think, rockets can and do fly in a vacuum. Fuel and oxidizer mix and ignite in a combustion chamber causing a controlled explosion that is directed out through the engine bell.
How fast is warp 1 speed in mph?
That means the Enterprise can travel 9,166.66 light years in 1 year (2,750,000/300). A light year is equal to 670,616,629mph. So at max warp the Enterprise can travel at 701,748,755.636mph (670,616,629*1.04).
Is warp speed possible in real life?
Seriously. Humans are one step closer to traveling at faster-than-light speeds. A new paper proposes a fully physically realized model for warp drive.
Will warp speed ever be possible?
Warp drives are theoretically possible if still far-fetched technology. Two recent papers made headlines in March when researchers claimed to have overcome one of the many challenges that stand between the theory of warp drives and reality.
Is a warp drive possible?
Outside of that, even greater speeds appear to be possible. “None of the physically conceivable warp drives can accelerate to speeds faster than light,” Bobrick says. That is because you would require matter capable of being ejected at speeds faster than light—but no known particles can travel that fast.
Is Quantum drive real?
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. The first Xi'an quantum drive was created in 25343 BCE by House Yaing.
What is EmDrive NASA?
Five years ago, NASA researchers experimented with an object called the EmDrive (or electromagnetic drive), a Y-shaped metal chamber in which, they reported, thrust could be produced without propellant.
How do people move in space without propellant?
Most famous propellantless methods are the gravity assist maneuver or gravitational slingshot of a spacecraft accelerating at the expense of the momentum of the planet it orbits, through the gravitational field, or beam-powered propulsion and solar sailing, using the radiation pressure of electromagnetic waves from a
Are FTL drives possible?
If humanity ever wants to travel easily between stars, people will need to go faster than light. But so far, faster-than-light travel is possible only in science fiction. In Isaac Asimov's Foundation series, humanity can travel from planet to planet, star to star or across the universe using jump drives.
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).
How fast is electromagnetic propulsion?
There is a 1–10 cm (0.39-3.93 inch) air gap between that eliminates friction, allowing for speeds up to 500 km/h (310 mph).
What is the most advanced propulsion system?
Antimatter also has the highest energy density of any known substance. And if used as fuel, it could provide by far the most efficient propulsion system, with up to 40% of the fuel's mass energy being converted directly into thrust (compared with 1% for fusion, the next most efficient).
What produces thrust in space?
Rocket Thrust. Thrust is the force which moves the rocket through the air, and through space. Thrust is generated by the propulsion system of the rocket through the application of Newton's third law of motion; For every action there is an equal and opposite re-action.
What is EM drive in salvation?
In the new CBS summer series, "Salvation", the EM-drive is introduced in the third episode as the propulsion system to be used to divert a large asteroid headed towards Earth: Salvation.
Is Impulse drive possible?
Unfortunately, there is no way around this. That's why impulse engines are often limited in science fiction to about 25% of the speed of light where relativistic effects would be minimal. The other challenge for such engines is where they operate.
What is the Mach effect?
Mach effects are transient variations in the rest masses of objects that simultaneously experience accelerations and internal energy changes.
Does NASA use magnets?
Scientists and astronauts make good use of magnets in outer space. Magnetism is one force that remains predictable out there and such predictability is valuable. NASA's Mars Rovers also use magnets to collect magnetic dust from the face of Mars.
Can a magnetic field move air?
Yes, the air can be magnetized but only very weakly and only when the magnetic field is present. Magnetization, by definition, is a spatial density of magnetic moments.
