Why not just put in on a skateboard or something? If the skateboard moves, it works.

Because, if it works, it produces so little thrust it wouldn't overcome the skateboards inertia.

How is it any different from a radiometer? One side gets heated up, hot air expands pushing the device forward a tiny bit. Radiometer uses ambient light an Meme drive uses microwaves but they both produce the same effect.

Because the MemeDrive also appears to work in a vacuum. When it had only been tested in air, convection and heating effects were still very viable explanations for it being bullshit; however, when experiments exclude these effects, a small force on the order of Shawyer's theories is still observed.

It could still be an artifact (something like electromagnetic interactions with the powerlines or test equipment) and if there is some new effect going on, it isn't necessarily the one predicted (maybe it's ablating copper ions out the back to make a very efficient electrical thruster). But we can rule out radiometer-like effects as the source of all the signal.

Radiometers are vacuum sealed too but achieving 100% perfect vacuum is difficult. It only takes a small amount of air to create the effect.

How did they achieve a perfect vacuum in their tests?
