According to the article, the charging is created by movement. So if that is the case, it would be unlimited flying. I can see that being a good and bad thing at the field. There are some people that just won't want to stop flying.

So long and thanks for all the fish!

This technology has been around for decades in wristwatches only it stores the energy mechanically in a spring. It is practical for devices that has low energy consumption since the amount of energy that can be practically captured in this way is fairly low. So for our helis this would not be a practical application. The bottom line is that you don't get anything for nothing, any energy that you are able to capture will indirectly come from the engine.

Hhmmmm, let's see if I got this, the electric motor creates motion that is converted into electricity that runs the electric motor.

I think I'm going around in circles.

So strap your heli in the back of your truck and go four wheeling for a week and then you could get in 15 seconds of flying. Oh, and also put some solar panels on the canopy and you could fly forever without charging. Another one is to put a propellor on the front of the canopy hooked to a generator and in fff you would get free amps. The possibilities are endless!

This falls into the "There's no such thing as a free lunch" category. The only way the Nokia phone would work is with the external energy of the walker shaking it. Therefore, I suppose with this technology you could shake your heli violently on the ground for a few hours to charge the battery instead of plugging it into your car battery or a wall outlet. Note, if you think that the heli can recharge itself by doing continual tic-tocs, keep in mind that the charging device will have an efficiency less than one, as does the motor, gear-train, rotors, etc, so you could expect to recover maybe a few percent of the expended energy at best, and with the additional weight and complexity of the charging system added to your heli.

What if you just extended your charger cables 1000' and had them connected to your lipo the entire time you were flying? Then you would be charging constantly

Use a y-harness between the connection to the esc

You guys are missing the point.
We have been able to charge watches with movement.
Now we can have cell phones that will never die. Who would have thunk it? I remember my first bag phone and that was the greatest thing going.
What will we be able to do tomorrow? In 5 years?
