They fund it, no?
Maybe, if that 0.05% is used against NASA by claiming it doesn't do its job how it should.

And I believe they actually did a serious job, which is probably why they never found any warp-drive ;-)
NASA pays small amount of money ($50,000 or so) and gives them a room to do experiments. Or at least did in 2011. Eagleworks and their team are not official NASA research. They just have facebook page. Contact attempts trough NASA don't work.
Glenn Research Center offered to replicate the experiment in a hard vacuum if Eagleworks manages to reach 100 µN of thrust.
