主题：无工质推进器 -- 五藤高庆

别想加速了，没用。理论上可以到3吨每千瓦推力。可是一做功推力就指数衰减了，能量和质量守恒，绕不过去的

The second generation engines will be capable of producing a specific thrust of 30kN/kW. Thus for 1 kilowatt (typical of the power in a microwave oven) a static thrust of 3 tonnes can be obtained, which is enough to support a large car. This is clearly adequate for terrestrial transport applications.

不过用来做浮空器倒是一个用途，不做功平衡重力梯度，浮空战舰满塞！

The device's operation as described seemingly violates several basic laws of physics, notably conservation of momentum, though the inventor insists to the contrary. John Costella, an expert in relativistic electrodynamics describes the EmDrive as a 'fraud'.[4]
