To be clear, the hoax part is that emdrive cannot be explained by the laws of physics.
The fact that photons can push is real. It has been measured. Simply apply newton's third law - for every action there is a reaction - and you get emdrive.
But, the engineers will probably show that the force is too small. The sun's illumination in space is very strong and it only pushed the satellites a few miles over several days?
