Yet inspiring too. Driven by his drive to understand, thus his attempt at bringing rationality to alchemy.qraalhttps://www.blogger.com/profile/13436948899560519608noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-39947932966615809522015-05-22T08:07:53.387-07:002015-05-22T08:07:53.387-07:00the question if it keem it's momentum is where...the question if it keem it's momentum is where came the momentum from if not from the inertial mass imbalance...<br /><br /><br />another idea from discussion, that resonate (Q>10 ;-> ) with some exchange on forums is that maybe it is not the simple EM field at the given frequency, but a parametric pumping.<br /><br />some exchange supports that the secret of Chinese Emdrive was that the magnetron was less stable than the Nasa VCO.<br /><br />I don't know well Parametric oscillators, but let us imagine that the inertial mass depend on the frequency and that you modulate Microwave frequency at good frequence (a multiple/submultiple of a cavity mode), then it may pump some momentum... a bit like a catterpilar, or a swimmer.<br /><br />Just a wild idea<br />(I'm influenced by recent Discrete Breather discussion)...Alain_Cohttps://www.blogger.com/profile/08352476615242858677noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-35257618446194924912015-05-22T07:49:08.586-07:002015-05-22T07:49:08.586-07:00No, it doesn't mean when energy input stops, t...No, it doesn't mean when energy input stops, the cavity must stop.

If we assume that the cavity walls are like the cosmic horizon in MiHsC then the photons at the wide end have more inertial mass, so they gain mass going from the narrow to the wide end (so mass-energy is not conserved in the usual way because the horizon causes energy from the zpf/Unruh field to become real). To conserve momentum then the cavity has to move towards the narrow end. This predicts the results quite well.Mike McCullochhttps://www.blogger.com/profile/00985573443686082382noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-77377237368948401392015-05-21T00:56:27.651-07:002015-05-21T00:56:27.651-07:00Hi,

My ...Yes, I saw that, and I love his open approach. My only fear is that his weight loss might be due to buoyancy/convection? He should take temperatures & estimate those effects, or try it upside down. If it's confirmed I'd love to know his Q value. Assuming Q=7300? and P=1000W? MiHsC predicts 15mN thrust, so for his 5kg setup that's a 1.5g weight loss.Mike McCullochhttps://www.blogger.com/profile/00985573443686082382noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-25464614186279759852015-05-17T19:52:32.392-07:002015-05-17T19:52:32.392-07:00Mike-
