EmDrive is the first true Propellantless Propulsion technology. High frequency electrical energy is directly converted to thrust. It is a resonant microwave cavity, shaped to obtain different group ...

The keys to EMDrive experiments are prove the propulsion is real and will work in space. Find a way with theory or experiment to scale up the effect. If it is real and the effect can be scaled up then ...

The article on “flying by light” describes a machine that uses microwaves to generate thrust. As I read it, I, like the thousands of other physicists who will have read it, immediately realised that ...
