  • The paper seems published emdrive.com/IAC2019Paper.pdf Quote from Roger Shawyer: “... This paper reports on a second programme of testscarried out on the SPR C-Band Flight Thruster. Thefirst series of tests, together with the design anddevelopment of the thruster was fully documented inDecember 2017 [1]. The original version of [1] wasissued as a test report in July 2010, as part of thedeliverable documentation for the Contract withBoeing, under Purchase Contract No 9CS1145H. Thiscontract was su…

  • newscientist.com/article/22186…late-the-laws-of-physics/ Quote from NewScientist: “NASA engineer's 'helical engine' may violate the laws of physics For every action, there is a reaction: that is the principle on which all space rockets operate, blasting propellant in one direction to travel in the other. But one NASA engineer believes he could take us to the stars without any propellant at all. Designed by David Burns at NASA’s Marshall Space Flight Center in Alabama, the “helical engine” exploi…

  • Let us hope the Emdrive par itself is enough satisfying (good shape, good frequency/phase) for the Emdrive to work or the supporters to surrender to evidences.

  • iafastro.directory/iac/paper/i…f.pdf?2019-03-28.12:18:32 Quote from Roger Shawyer: “Abstract EmDrive is the name given to a new propellant-less propulsion technology which has its origins incold war missile research. The subsequent development work has been shrouded in secrecy and publiccontroversy, and has therefore been largely overlooked by the wider propulsion community. With thetechnology now maturing, it is time for EmDrive to come out of the shadows. This paper examines oneaspect of EmDri…

  • A very educative video explaining keys about MiHsC/Quantized Inertia theory developed by Michael McCulloch youtube.com/watch?v=VYdebV9YlnI&feature=youtu.be Michael McCulloch endorsed it as "great" on Twitter, sot it seems correct.

    It seems only based on 2016 Chinese media, and some Chinese locutor said there was in fact nothing work on EmDrive despite the images... Current time is depressing. Latest test by Tajmar was very good about measurement, and negative...maybe did he build a weak EmDrive, or tpasted it, but his method looked top quality. Need more.

  • Michael McCulloch's paper on QI-thrusters, recently accepted by the J. of Space Exploration is now available as a preprint here: researchgate.net/publication/3…on_from_Quantised_Inertia Propellant-less Propulsion from Quantised Inertia Propellant-less Propulsion from Quantised Inertia M.E. McCulloch December 2018 Plymouth University, PL4 8AA, UK. Abstract A new model for inertial mass, quantised inertia, that predicts galaxy rotation without dark matter, also predicts that a highly-accelerated s…

  • Tajmar produced a paper about a very well done experiment, but with a negative result. researchgate.net/publication/3…ect_and_EMDrive_Thrusters I'm worried, but that is the rule of science. At least he set a new standard on what should be done to confirm EmDrive&co Quote: “Forces claimed by potential propellantless propulsion systems like the Mach-Effect thruster or the EMDrive are in the µN or even sub-µN range. In this paper, an automated thrust balance design capable of measuring forces of 10…

  • I hope this can allow to clear the MiHsC question clearly, if possible with a success. The claims are very convincing, but I cannot check if all is solid, and normally there would be some missing details to cleanup (unless Mike is lucky).

  • From DamianMłodziankowski @dmlodzian on twitter I got those conference slides from Roger Shawyer (published on emdrive.com) emdrive.com/dresden2018.pdf Maybe it was already published here... I don't remember. about German test that fueled the skeptics, note that page 29 Shawyers state "Very low Q"... while in all his presentation it is clear high-Q is key factor. page 30, the dresden test iw clearly coherent with ofthers experiments but with very low Q compared to others, even NASA.

  • A followup article that is considering that worrying result, but introduces more questions: nextbigfuture.com/2018/05/145239.html Emdrive could be mainly magnetic effects but there is still more testing to be done

  • Beside worrying presentaton by Dr Tajmar, Breajthrough Discuss conference featured Dr Halrold White, who is scaling his EmDrive to 400W. Beside that he is pushing a theory. Quote from NextBugFuture: “His theory is that Acoustic resonances in the quantum vacuum are directly responsible for atomic structure Applying a time-varying electromagnetic field using simulation and experimentation He then has force predictions ” nextbigfuture.com/2018/05/sonn…riments-to-400-watts.html the paper can be requ…

  • Next Big Future reports (like many) the worrying results of Dr Tajmar with his EmDrive experiments. It seems his thrust can be attributed to twisted pair in earth magnetic field. The paper is there researchgate.net/publication/3…and_Mach-Effect_Thrusters nextbigfuture.com/2018/05/the-…ach-effect-thrusters.html Quote from NextBigFuture: “Tajmar is finding more magnetic interaction from cables. He is not conclusively saying that is all that is happening with EMdrive or Mach Effect but he thinks it…

  • It is new to me, and it seems after a surface reading a good review to start with. I like the conclusion as it is operable...

  • This seems a sane position. Someone in LENR use the concept of "Conservation of Miracles", which states that when you have multiple anomalies, they are probably related, as having two murder in the same building is probably not just two independent "anomalies"... Michael McCulloch is pushing the concept very far, in trying to use MiHsC to explain LENR too... I'm not convinced, but if EmDrive, Mach, LENR, and darkmatter/energy had the same origin, it would save much work for physicists.

  • Is the article serious (published on Apr1?). All looks stated seriously, gathering old references, but mybe I missed a point. Nasa article is March 30, so looks serious. nasa.gov/directorates/spacetec…sion_Interstellar_Mission Is there any parallel/difference description with EmDrive, and interpretation relatively to MiHsC model? I did not follow Mach effect, theory, nor experiments ....

  • Interesting for frequency stability I imagine, but probably low energetic efficiency? however maybe can it serve to lock a high efficiency MicoWaves generator, like travelingwave tube... It seems Shawyer's recent patent introduce a phase condition... Not sure Maser is useful (condition as I understand is more having a VCO controlled by phase difference in the cavity). Good news for clocks.

  • Hard to answer without a confirmed theory. What would be the expected for the thrust of a solid state maser, or why not a gas maser ? It seems the energetic efficiency and density is very low compared to a magnetron?

  • Thanks. I Cannot verify the details, but the approach is very interesting. To understand what is the phenomenon, and what candidate theories can be eliminated, one way is to look at the behavior of the function for thrusts from design parameters, especially dimensions. One interesting point is this study is that it account for the behavior of Q with dimensions. One common error in such studies is to assume "all else being equals" while in fact many parameters assumed stable , depends (like Q) fr…
