This is an attempt to explain a controversial experimental result that appears to violate conservation of momentum. The experiment consists of flooding a resonant cavity with microwaves and measuring the thrust produced, which should be zero but is measured to be some small positive number. The explanation in the paper uses the quantum vacuum. The funding of these type of experiments are always interesting to explore.
