From following EmDrive work a little, my impression is that nobody has the budget to do a high power setup right. Budget was a major limitation in the published NASA work. Also, some artifact sources (e.g. power lead/B field artifacts) would scale up along with power.

- ridgeguy 10y agoI agree. I think it would be less expensive (but not cheap) to build definitive test equipment on Earth than in space. Space operations also might cause new types of artifacts. One such might be forces from induced currents due to spacecraft motion relative to the Earth's magnetic field. I think it's just expensive to do a really definitive physical demo in this domain, given that the effect (if there is one) is so small and sources of artifacts so numerous.

- kobeya 10y agoActually cube sats can be pretty damn cheap. A cube sat test rig with off the shelf components could be cheaper than a custom ground experiment.
- walrus01 10y agoSufficient watt hours per day to prove this are not available from the PV cells you can mount on a cubesat.
- euyyn 10y agoPlus you have to pay for launch, even if you piggyback.
- andygates 10y agoThere aren't even published controls -- the test rig with a non-resonant horn, for example -- so we're way ahead of flight testing.
