Lemming3K my man,
I am glad you brought up the antimatter subject. Fascinating, fascinating, fascinating, did I say fascinating or what? You are right I do have some physics to catch up on. I have some white papers for your professor to look at.
First take a look at NASA's attempt at harnassing this incredible resource. My hat is off too ya dude
Here is the NASA white paper, check it out and I am sure your professor will be pleased:
NASA Antimatter Propulsion Systems
Next let me try to engineer this propulsion device a little if you don't mind. I worked in generation planning for an electric utility for 5 years and I evaluated all kinds of new technoligies for feasibility. This project is far more interesting than any technolgy I ever looked at including nuclear PWR, ALWR, wind power, geothernmal, Israeli desalienation project, to name a few.
Before I proceed, let me say I think the physics going on here can fit within the current energy laws as I know them, and I am ready for an education here if needed.
As an engineer I have three major problems to tackle with this technology:
Production of the fuel (antimatter),
Control of the energy process (mass annihilation)
Disposing of the waste products back to the universe from which they came.
Each of these processes has a relative efficiency, and to look at the overall process efficiency I must multiply the three efficiencies together. This will tell me what is going on with entropy as well.
1)The relative efficiency of the anti-matter production process can not theoretically excede 50% according to the NASA paper. OK the second law of thermo is satisfied. This efficiency then is assumed to be .50 under the best theoretical possibilty. (Current antimatter production processes are much less efficient than that).
Let's keep going:
2) The annihilation process satisfies the first law for conservation of mass/energy if you consider antimatter to be mass. This process could be as much as 200% efficient (previously thought an impossibility), that being = to 2. Man, what a problem there is with containing the beastie, and this surely will not be free! Somebody has to hold this thing with a magnetic field, there has to be a loss here. So I'll say less than 2. Let's call it ~2.
3) The disposal of the waste products back to the universe poses a problem, but let's ignore that for now and assume it can be 100% efficient, that being equal to 1.
Now I multiply the three and I get .5 * ~2 *1 for an overall process efficiency of ~100%, when I look at it from start to finish. The energy I "throw away" is then at a minimum whatever it takes to suspend the antimatter particles = ~100% and the devil is paid his dues at the magnetic field, (no pun intended). The overall net effect then is that entropy increases in the universe (the expected result). So the laws of energy are obeyed when you look from start to finish, though the uptick at annihilation is something new -- i.e. getting 2 fers.
I also read some about a parallel universe (nobody has seen), and supposedly our universe can be made a PMM with this alternate universe where antimatter could exist. That is something I have not studied.
All things considered I don't think you can get 100% efficiency from start to finish, and this is what the second law tells us.
I am eager to learn. Tell me more.
By the way, gravity acts on an object in a vacuum at ground zero (earth surface), gravity acts on the object inside the vacuum container the same as any other object. I checked with one of my engineering buddies at the development testing lab where I work (he has a masters degree in mechanical engineering). He agrees on this as a fundamental concept.
I like you Lemming. Give your professor my complements.
