There is a world famous Doctor, Dr. Jordan Kare.. Now, what he's world famous for happens to be writing a song.. That song is called: Fire in the Sky (I have a very good copy of that song, as well as a mp3 of Dr. Kare himself singing it) He is a genuine rocket scientist by the way (Designs rockets for a living) His current "pet project" is an ice engine.. basically you fill a reaction chamber with water, Freeze it solid, sit it atop a ground mounted laser, and shoot laser beams into it, first melting ice, then boiling water, making high pressure steam which then propells the rocket.
Will it work? Well.. I am not a rocket scientist.. but it sure looks good on paper. Non-polluting too.
Another song by Dr. Kare is called, "The Designer" I do not have the lyrics on this machine.. At lest I do not think I do.. And I did not but I finally got lucky with a web search:
The Designer
The designer sat at his drafting board
A wealth of knowledge in his head was stored
Like "What can be done on a radial drill
Or a turret lathe or a vertical mill?"
But above all things a knack he had
Of driving machinists completly mad.
So he mused as he thoughtfully scratched his bean
"Just how can I make this thing hard to machine?"
If I make this perfect body straight
The job had ought to come out first rate
But would be so easy to turn and bore
That it would never make a machinist sore
So I'll put a compound taper there
And a couple of angles to make them swear
And brass would work for this little gear
But its too damned easy to work I fear
So just to make the machinist squeal
I'll have him carve it from tungsten steel
And I'll put these holes that hold the cap
Down underneath where they can't be tapped
Now if they can make this it'll just be luck
Cause it can't be held by dog or chuck
And it can't be planed and it cant be ground
So I feel my design is unusually sound.
And he shouted in glee, "Success at last!
I've designed a part that can't even be cast.',

I believe this is Dr. Kare's work, but the author of the web page had some of tey lyrics wrong too.
