Two brake questions.

I'll look around for a little red wagon and a bowling ball... I have model sailboat and a fan but it sunk when I put the fan on it.
 
Actually, the bowling ball example isn't quite appropriate. In fact, if the bowling ball weighed more than the wagon and passengers, the wagon would move backwards as the ball is thrown forward. (Something about Newton's Law....)

Depending on the design of the sail and the location of the fan, the boat would indeed move forward. There would be a slight amount of "spill" from the curved sail that will cause a very slight forward motion, and since the fan is steady (depending on the length of the extension cord), the boat would continue to move forward. Also, there will be a pressure differential from the front to the back of the sale, the sail will try to move into the lower pressure at the front of the sail, carrying the boat with it...............

This is just bizarre!!

It's no wonder the Green Lobby has gained such a foothold on America's throat.

There's actually an electric car proposal out there, I #$% you not, that has proposed FANS ON THE ROOF to "generate energy from forward movement" for use in recharging the batteries..... and of course when you park said vehicle "you park in such a way that the prevailing wind charges the system." It's in the development stages yet" and the proponents have "realized that larger, more fluid parking accommodations are needed"...............

but I'd better just STOP


before I start going sideweays



wheewwwwww

If the fan is blowing air and the sail is only 'catching' a portion of that air, then the fan 'power' is more than the sail' power' and the boat should slowly move backwards, the way the fan is inefficiently 'pulling' it...
 
Roy,
I just don't know about you...

I suppose you could also stand in the bed of a pickup truck, push on the cab, and make the truck go forward?

Dennis,
I hope the fan wasn't plugged in. It could distort your future responses. :)

Best,

Al,
I bet the oil companies have been keeping this a secret and it just leaked out recently. What an idea! Did you happen to see if they said this would generate enough electricity for my cell phone and portable dvd player so I can use them while I drive? That way I could use the free energy from the air vs having my alternator lug the engine down to do it. Or perhaps it will generate enough electricity that the car will have a surplus now? Like having a windmill of your own at your house and selling the power back to the utility company. My only question then is, would I be selling this electricity back to Pennsylvania Power and Light, or would it go to Exxon at the service station? Maybe now there'll be new "Unfilling stations" where you drop off your charged battery and pick up a dead one along with some cash.

The possibilities are endless...

Much of innovation in the auto industry is driven by racing. What body of racers found this cause I've not seen any fans on the top of NHRA dragsters or Nascar stockers... Or even on F1's or GTP's for that matter.
 
this post brings back old memory,s of my old uncle he would go to the pub with 2 buckets when he got so drunk that he could not walk home. he would stand in the
bucket,s grab the handles and carry him self home. :)

Ha ha ha, I think I know your uncle Ted.
Used to drink with him and sometimes he had to carry me also.
