Chinese Creating First Warp Drive? More formally known as the "electromagnetic drive," or "emdrive" for short, this steampunk-looking device converts electrical energy into thrust via microwaves, in a way that some physicists believe is impossible. But the Chinese claim they're building a prototype right now. British scientist Roger Shayer caused a stir when New Scientist highlighted his claims that an em drive could violate strict Newtonian physics, thanks to an effect of Einsteinian relativity. The drive works by filling a "tapering resonant cavity" with microwaves. Critics have dismissed Shayer's idea as another perpetual motion machine, and the British government cut off his funding. But his assocation with China's Northwestern Polytechnical University in Xi'an paid off, and the NPU team has been able to confirm Shayer's work independently. They also claim they're building a a thruster based on Shayer's theories. Link.
