I ask the same thing about these posts that bitch about Comcast non stop ! Just fucking switch or stop using it bro ! Oh wait . <| sep |> lmao . I don ' t know why , but I love it when people not having English as their first language make mistakes like this . It ' s cute for some reason . Thought I ' d share this . maybe to distract myself from the sickening general discussion of the article itself . <| sep |> I don ' t think you understand well what the EM drive imply . Even tho it is less efficient than the current technologies , it does not require any propellant . And accelerationtime is the derivative of speedtime , meaning that for a constant acceleration as small as it is you get a power 2 speedtime function . The problem with current means of propulsion is that once in space you can not indefinitievly accelerate , you run out of fuel , but with an EM drive you could for exemple use atomic energysolar energy for propulsion , wich we currently can ' t except for solar sails ! For exemple if you were took a 538 tons rocket falcon 9 before take off , and you got it to it ' s release rate you ' d get a speed of 1210104 t 2 release rate ms with t elapsed time in seconds . Of course it would mean a lot of power , all we need is to devellop more efficient power sources . PS sorry if it does not sound clear but my english is not the best
