Actually you just explained his idea, no? The difference between the dense particles just behind the craft with maximal drag and sparse particles just in front

Actually you just explained his idea, no? The difference between the dense particles just behind the craft with maximal drag and sparse particles just in front, means a pressure differential pushing the vehicle forward
