Re: [Vo]:Nextgen EM Drive's Potential seems way above the Theoretical Limit

2015-05-10 Thread David Roberson
It concerns me that an observer on Earth will notice that the mass and thus energy of the stationary car held up by the drive is becoming lower with time. He will not find where that energy is being deposited as the mass drops. The heat due to cavity loss can be calculated directly, but any

Ok, well if it is used for static thrust only, it is then a coin toss if it would work opposing gravity as static on the surface of the earth experiences 1G of acceleration. According to the equivalence principle... On Mon, May 11, 2015 at 4:27 PM, Craig Haynie cchayniepub...@gmail.com wrote:

Thanks Robin. You're right. He does say that this force of 1 tonne per kilowatt is for 'static thrust'. I found an answer from the website. He is referring specifically to a 'static thrust', not used to do work. The static thrust/power ratio is calculated assuming a superconducting EmDrive with

A reactionless drive tends to break the conservation of energy by just existing. Since there is no equal and opposite energy does not balance, double the velocity would be achieved with double the energy but yield 4 times the stored energy, eventually that leads to excess energy out. Now in the

Hello! I was hoping the Vorts could help me with this. Roger Shawyer, at minute 2:56 in this video, claims that the next generation EM Drive could generation 1 tonne of thrust per kilowatt of power. This means that a 1 tonne car should be able to hover above the ground for the price of one

His claim is 1 tonne of thrust per kilowatt. One tonne of thrust will accelerate an object. An object under the acceleration of gravity will be countered by the thrust, costing 48 kilowatts of power in the process. This is not the same as suspending an object by a rope or something. Are you
