Evaluating NASAâ€™s Futuristic EM Drive
J Thoendell stashed this in Space
The tests reported by Dr. Whiteâ€™s team in July 2014 were not conducted in a vacuum, and none of the tests reported by Prof. Yang in China or Mr. Shawyer in the UK were conducted in a vacuum either.
The scientific community met these NASA tests with skepticism and a number of physicists proposed that the measured thrust force in the US, UK, and China tests was more likely due to (external to the EM Drive cavity) natural thermal convection currents arising from microwave heating (internal to the EM Drive cavity).
However, Paul March, an engineer at NASA Eagleworks,Â recently reported in NASASpaceFlight.comâ€™s forum (on a thread now over 500,000 views)Â that NASA has successfully tested their EM Drive in a hard vacuum â€“ the first time any organization has reported such a successful test.
To this end, NASA Eagleworks has now nullified the prevailing hypothesis that thrust measurements were due to thermal convection.
A community of enthusiasts, engineers, and scientists on several continentsÂ joined forces on the NASASpaceflight.com EM Drive forumto thoroughly examine the experiments and discuss theories of operation of the EM Drive.
The quality of forum discussions attracted the attention of EagleWorks team member Paul March at NASA, who has shared testing and background information with the group in order to fill in information gaps and further the dialogue.
This synergy between NASASpaceflight.com contributors and NASA has resulted in several contributions to the body of knowledge about the EM Drive.
Okay but there's still a lot of skepticism. There's still a lot to do to figure out if this can be practical.
