Light pressure: A pressure of 100 newtons/meter^2 = 100 pascals on a reflective mirror, is achieved with beam power 30 gigawatt/meter^2.
--Even if the mirrorfilm were 99.9% reflective, that'd mean said film would be absorbing 30 megawatt/meter^2 from this beam, which would have to be compensated by blackbody radiation for cooling, which would force the film to have a temperature of 4000 kelvin (calculation using stefan boltzmann law). This is even assuming a mirror film that reflective could at the same time be an excellent blackbody, which seems a contradiction. So that seems another damning obstacle. So yah, I think I've found enough problems in 15 minutes to kill the entire project that was claimed. Can I have my $100 million now?
