Mr. Kryptid ,Trick to everything , isn't there ? Mr. Einstein said it ; E = MC2 . Convert some of the momentum energy to heat energy , and you have a net loss of momentum , and a gain in heat .
EM waves transfer energy well , but not momentum .
How do you think a plane flies ? TRICK ! P.M.
Janus , your faith in your paradigm is extraordinary
Mr. Einstein said it ; E = MC2 . Convert some of the momentum energy to heat energy , and you have a net loss of momentum , and a gain in heat . EM waves transfer energy well , but not momentum .
I'm not going to go deep on the associated ( and convoluted ) formulas . The fact that the thrust produced by a 1 gigawatt laser ( a large cities worth ) is less than 1 pound makes the point . The same energy put into a 0 G ball-bouncing drive would produce OVER 100,000 lbs. of thrust easily . Momentum MAY be conserved , ENERGY always is . To critique my designs , accurate & complete numerical values are necessary . These are basic , mechanical machines, not intricate , relativistic experiments . Anyhow , I always welcome well- intentioned debate , I just prefer easily measurable & transparent processes and quantities , to opaque & formulaic obfuscation. Alright , my mechanical mind has to roll out . P.M.
Momentum MAY be conserved
A 25 to 1 ratio in KE makes for an excellent propulsion mechanism , with no propellent necessary .
Kryptid ,The random quiverings of the component molecules ( radiating random photons ) do not exert a significant net force on this system
This is why EM is good at transferring heat , but not push.
As to usage , you'll just have to ask Mr. E.M. . He needs it a lot more than I do , he wants to get his car back ! Don't ya dig my sense of humor now ? Signing off , P.M.
Mr. K. ,You have made a good suggestion ! Let's " start the reaction ..." and see what happens ! I suggest you use a small boat , and compare the two ball throws . Don't worry , I know a good eye doctor who can get your eyes back in after they pop out staring in disbelief . When you finally see a boat w/no propeller , just remember 'Ol Professor ! Toodles . P.M.

To : Pimby Phi & Janus Effect .Oh ye of little faith ! It doesn't need to be THAT complicated ! All you need is a system of circulating momentum . Transmute some of that mom. energy (unidirectionally) into heat energy , and your R.Drive will push in one direction . Think of a free-floating Hot Wheels track with a bunch of pinball circulating on it . If you suddenly convert the momentum energy of one ball to heat , the resulting collisions will cause the entire track to move in one direction , as a unit . Consider this a hint , because there's a 100 ways to skin a cat .........................Professor Meg.
A typical inelastic collision distributes it's kinetic energy as follows : 45% heat / 55% final motion . A 1kg. sand bag @ 30 mph. has 50 joules of KE .
