    In major international tests, the physics-defying EmDrive has failed to produce the amount of thrust proponents were expecting. In fact, in one test at Germany’s Dresden University, it didn’t produce any thrust at all. Is this the end of the line for EmDrive?

    (© Elvis Popovic/CGS Society) PHYSICS In a Comprehensive Test, The 'Impossible' EM Drive Has Failed to Produce Thrust… Again PAUL M. SUTTER, UNIVERSE TODAY5 APRIL 2021 The EM Drive is a hypothetical rocket that proponents claim can generate thrust with no exhaust. This would violate all known physics. In 2016, a team at NASA's Eagleworks lab claimed to measure thrust from an EM Drive device, the news of which caused quite a stir. The latest attempt to replicate the shocking results has resulted in a simple answer: the Eagleworks measurement was from heating of the engine mount, not any new...

    The "EmDrive" claims to make the impossible possible: a method of pushing spacecraft around without the need for — well, pushing. No propulsion. No exhaust. But the EmDrive doesn't just violate our fundamental understanding of the universe; the experiments that claim to measure an effect haven't been replicated. [A]ll forms of rocketry (and indeed, all forms of motion across the entire universe) require conservation of momentum. In order to set yourself in motion, you have to push off of something. Your feet push off of the ground, airplanes push themselves off of the air, and rockets push parts of themselves...

    So... it could still get us to Mars in 70 days? Physicists have just published a new paper that suggests the controversial EM drive - or electromagnetic drive - could actually work, and doesn't defy Newton's third law after all. In case you've missed the hype, here's a quick catch-up: a lot of space lovers are freaking out about the EM drive because of claims it could get humans to Mars in just 10 weeks, but just as many are sick of hearing about it, because, on paper at least, it doesn't work within the laws of physics. Despite that...

    As the 21st century unfolds, radically different forms of air and space vehicles will replace the clunky machines of today, whisking passengers at ultra-high speed around the Earth and outward into space. Laboratories scattered around the world are delving into novel and exotic forms of propulsion. Breakthrough physics could well make possible ambitious human treks across interstellar distances. Work is underway to harness antimatter as a way to shave travel time to the Moon down to minutes, or between Earth and Mars to a day. Meanwhile, laser and microwave technology is rapidly advancing the idea of beaming people and payloads...
  • Testing shows using microwaves to propel a craft into space might work

    07/23/2015 12:10:47 PM PDT · by Red Badger · 28 replies
    =============================================================================================== A team of researchers at Colorado based Escape Dynamics is reporting that initial tests indicate that it might really be possible to launch space-planes into space using microwaves sent from the ground, to allow for a single stage spacecraft. If the idea pans out, the cost savings for sending satellites (or perhaps humans) into orbit could be considerable. Today's rockets are all based on the same idea, a multi-stage rocket is used, each part filled with propellant that pushes the rocket into space as the propellant is burned. It is a really expensive way to go because the propellant...

The least extreme is a patent for Piezoelectricity-Induced Room Temperature Superconductor. The other two patents are gravity wave generator and inertial mass reduction.If these could be realized as technologies then we are talking Star Trek level spaceships. The gravitational wave generator could be used for propellentless propulsion to near the speed of light. Being able to reduce inertia would also mean capabilities which currently seem beyond known physics.The more likely situation...

    Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg, Germany have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications. The vacuum is not empty. It may sound like magic to laypeople but the problem has preoccupied physicists since the birth of quantum mechanics. The apparent void...

    M Drive, the microwave radiation thruster capable of propelling a spacecraft without any fuel, has been heating up the debates over the past couple of years. The concept of EM Drive has been facing harsh criticism as it appears to violate the Newton’s Third Law of Motion, which says that every action has an equal and opposite reaction. In a recent development, a full and official peer-reviewed paper on EM Drive has been published online. This paper has appeared via the American Institute of Aeronautics and Astronautics (AIAA)’s Journal of Propulsion and Power. While the publication of this paper doesn’t...

    The laws of physics have won again, it would appear. For the past few years, researchers at NASA's Eagleworks advanced-propulsion lab have been putting a controversial and potentially revolutionary space engine called the EmDrive to the test. The EmDrive, which was originally developed by British scientist Roger Shawyer in the early 2000s, purportedly generates thrust by bouncing microwaves around inside a conical chamber. Because the engine doesn't require any fuel, it could theoretically make spaceflight far cheaper and more efficient, opening the heavens to exploration The EmDrive really shouldn't work. The engine doesn't blast anything out a nozzle, so Newton's...

    The EmDrive propulsion system might be able to take us to the stars, but first it must be reconciled with the laws of physics. Giulio Prisco is a futurist, theoretical physicist, and computer scientist. He writes about science, technology, and the future. He's also a cofounder of Space Cooperative. A tentative theoretical explanation for the mysterious, "impossible" EmDrive propulsion system was published in the Journal of Applied Physical Science International in August. First proposed by British engineer Roger Shawyer, the EmDrive is an asymmetric box that looks like a truncated cone, with a standing microwave field inside that—apparently violating known...

    The results of NASA's tests on the 'impossible' EM Drive have been leaked, and they reveal that the controversial propulsion system really does work, and is capable of generating impressive thrust in a vacuum, even after error measurements have been accounted for. The EM Drive has made headlines over the past year, because it offers the incredible possibility of a fuel-free propulsion system that could potentially get us to Mars in just 70 days. But there's one major problem: according to the current laws of physics, it shouldn't work. The issue is the fact that the EM Drive defies Newton's...

    Until yesterday, every physicist was laughing at this engine and its inventor, Roger Shawyer. It's called the EmDrive and everyone said it was impossible because it goes against classical mechanics. But the fact is that the quantum vacuum plasma thruster works and scientists can't explain why. Shawyer's engine is extremely light and simple. It provides a thrust by "bouncing microwaves around in a closed container." The microwaves are generated using electricity that can be provided by solar energy. No propellant is necessary, which means that this thrusters can work forever unless a hardware failure occurs. If real, this would be...
