Now... it may be just me, but I have a few queries:
a) 'can' in no way affect? I think you mean 'under my testing it did not'. What angle did you light it? See again the radiometer...
b) We live in an age where we can put a webcam with motion detection on a subject for free... why didn't you do that? Or better yet, put a livestream on, lots of sites like ustream... have a television program running in the background so interested people can watch it for you...
Also, did you verify that without any effort it *did* move first?
As the basic rule is; you need to be able to do something that is not probable; so if it almost did not move without you trying....
c) You know it doesn't count if you glue/stick the weel to it's axle, right?
