Congratulations! (On getting your proposal accepted and published to the site, not on getting blotto.)
I hesitate to comment, because you obviously did a lot of work and most of it is beyond my scope of criticism. If what I have to offer is less than helpful, please feel free to dismiss it out of hand.
I think the written explanation of your idea could use some fine tuning.
e.g.
I do understand the word limit and other constraints, but a lot of it seems clunky to me.
I mean this as a useful critique, although I must admit I am consumed with jealously. My idea for a car powered solely by my sense of self-satisfaction was rejected.
Isaac Asimov space ship engines were often, basically, steam engines. It must be quite fun to have any sort of interaction with NASA. I would be quite proud.
(I bet you if you had data cassette programming for your car they would pay particular attention)
