Pretty cool

Would work pretty good on that one way commute!

 

Just make sure you look out for those underpasses

 

Didn't do a very good job of explaining the 'energy storage' details....
I'm close to calling 'shenanigans' on this one......

 

I am going down to the hobby shop, getting a propellor, the longest piece of all-thread I can find, thread the center of the prop, and get it turning smoothly. Then measure wind speed and compare to how long it takes the prop to spin itself along the length of all-thread when facing into the wind.....maybe

 

Speaking of wind power, here's a video of a windmill that explodes as a result of RPM runaway due to brake failure.

If you ever seen the sheer size of these things, you can appreciate how dangerous this condition can be.

 

It's not a propellor, no more than the rotor on a helicopter is a propeller.

It's a wing, and by spinning it, it creates lift.

Placed horizontally.

 

I wonder if this would work with boats.
