Re: Space Voyage #1

Who could ask for a better crew than this. I am surrounded by geniouses!

Welcome aboard the Prophesy, Janus. You are offered the role of our Nuclear Propulsion Engineer (unless you prefer a different title). Along with our resident Astrophysicist - JQ - I am sure we will have discovered the plausible limits of our propulsion system and fuel supply in no time. I am open to all suggestions for how our main engine and fuel tank should best be configured, and I will concede that the Prophesy is probably more of an RV than a Ferrari. So the lower extended thrust is probably appropriate. Although I will reserve the right to keep the potential of 1G accelleration for emergencies (at the cost of fuel economy).

So...

Suggestion: Our tank is filled with spent nuclear fuel that is a single step from being turned back into enriched uranium. This way the whole tank can be filled with the stuff, but in a fairly stable way. As the fuel is brought to the engine it is enriched in line before passing into the engine.
Question: Is that plausible? (By the way, one way we are financing this whole affair is by having the govenrment pay us to dispose of the nuclear waste that we are using as fuel)

Consider the fuel to be the most energetic enriched uranium. What is the highest amount of energy that we can expect from a ml of that stuff, and what percentage of that energy can ce convert into motive power of the ship? The higher we can get these number the better off we are.

And in answer to your question Janus, The sections are straight. There will be a weird effect near the ends as the gravity will be a bit angular. But we will get used to it. I have them straight because a banana doesn't fly straight. These are assembled on the ground and lauched as completed units. It will add character to the experience. Ever been to "the mystery spot"?

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
