Well, this may be a bit out of line from what you were thinking but what about using an RC car or airplane nitro engine? I think that would be pretty cool. For propellers check your local hobby shop for ones used on RC planes. They come in all different sizes and pitches and are pretty cheap.

At a garage sale today I saw a 3HP verticle shaft engine lawnmower for $5. I didn't buy it because I couldn't think of anything to do with it but hey, what about a really big hovercraft? Like one that you could ride on. Then you could get a horizontal shaft engine to propell it.

that's pretty cool. I tried making an unofficial one during the build season. I connected two alligator clip wires to a 14.4 V battery to a 4" muffin fan. I had some problems, because the alligator clips (which were metal and unshielded), touched and a wire burned, pretty badly. I don't think i'll work with circuits again.

Anyways, about the K'nex thing, its great if you can get it to work with other devices. I have played with K'nex for about 11 years now and I have had a lot of trouble making it work with other devices, such as coffee cans, etc. Since the K'nex rods and connectors are not of a uniform length (that is a rational number, in inches or centimeters), it is very hard making it work with objects that have rational numbers of lengths. Congratulations!!

P.S. don't use alligator clips!!!
