Hi All,

Colin Q. posted notice of an electromagnetic propulsionless drive,
more info about which can be found here.

Here's a link to Shawyers patent, GB2399601

Remarkably, it's only been patented in the UK. Given the
value of the device if it proves functional, I'm left
a bit slack jawed about that... You would think he would
have ignored GB and gone straight to WIPO. 

Anyway, it's promising that the device exhibits positve and
negative thrust depending on direction, so we can
rule out thermal effects. And simple radiation pressure ought
to be orders of magnitude lower than what he measures.
How about that?
