Re: Would this work?
[ QUOTE ]
Imagine I'm sitting in a sailboat, and have a battery operated fan. I point the fan at the sails - will the boat move forward? What if the fan has an external power source?
Is that like pulling yourself up with your own shoelaces?

it wouldn't work. the fan would push you backward more than forward. if you turned the fan around and pointed it behind you (like a fanboat) i think it would help you a bit.
