Mess with your minds: A wind powered craft going faster than a tail wind speed.

A wind powered craft going faster than A TAIL wind speed.
It's for real...



Anyone here thinks it's impossible?
If so, watch the video again...

I don't get all the apparent resistance from the people once the principle is explained. I somehow have no issues with it and don't really need a full scale replica to believe it.

Now, airplane taking off from a treadmill still takes an effort to figure out.

I'm not sure why I would think it's impossible?

For an EE analogy: I plug an inverter into a 12 V socket and get a 120 V output voltage which is higher than the input voltage. Anyone here think that's impossible?
Red Squirrel:
I've always been intrigued by a similar idea myself: Could a wind powered craft go AGAINST the wind?   Basically you're still harnessing the wind's energy so it's not really overunity but at same time the idea of going against the wind by using the wind feels like it breaks laws of thermodynamics.  I think it would be equivalant to using a hydro electric generator to pump water back up the dam.
