Drafting idea (using sails)
How about a sail like on a sail boat, have a winch run up the sails and masts with the flip of a button, a big truck should create enough suction to drag a civic behind it

Have you see the Unicorn lounge ?

I think a truck doesn't pull the wind forward, it just provides a barrier and lessens the force of the wind. So having sails would counter the effect of the truck, would catch more of the wind and slow down your car. |
...if you're close enough to draft, why not just use a "tow-rope"?
|
Yeah..a tow rope attatched to a giant fuel magnet, so you can change trucks when one turns off.
....and some people say those fuel magnets aren't good for anything, HA! |
Something ive thought about before :)

In theory you might see a small gain, but in practice not enough to sacrifice safety. At that distance a tow bar would be much better. |
i've seen guys in my hometown draft behind Semi-trucks down main street when it's not busy, watched one guy go about 1 1/2 miles without peddling at all. a little too risky if you ask me

This idea has been done, but it does not work by trying to grab on to the suction behind a large truck because that suction would have to be a perfect vacuum in order for it to pull you, but large trucks do also create a strong cross wind as they push thru the air and someone has built and tested a vehicle that took cross wind and made it in to forward motion with a wing of sorts, because just like with a sail boat you can not travel in the same direction of the wind as fast as that wind.
http://bks2.books.google.com/books?i...aFeaSAbmOnFm6g Popular Science - Google Books So yes, the idea of a sail can be laughed at but that is mostly because a sail works as a wing, not a cup that catches the wind, a wing creates lift and when put on a boat or a car that lift is turned in to forward force so a 15mph wind can push you forward at 30 or 40mph. |
I've been toying with the idea of attaching the kite from one of these Kite buggy - Wikipedia, the free encyclopedia to the Insight, for trips out to central Nevada. Once you get east of Fallon, there's not a whole lot to worry about in the way of power lines or other traffic...
