mechanical LED flashlights?
According to wikipedia (http://en.wikipedia.org/wiki/Dyno_torch), a flashlight under tension (or torch dyno) has a device called the flywheel can store energy. From this, the user presses a handle to operate a small dynamo provides power power to a miniature incandescent bulb to work. My questions are: 1. How much energy stores it in the wheel? 2. How much energy is produced Inject when driving? 3. Is it possible that this mechanism to generate enough power (with some modifications if necessary) to make a hand fan to be used (Eg http://a248.e.akamai.net/f/248/5462/2h/amplestuff.safeshopper. Com / images / W0fks5v.jpg)? Thank you very much!
1. Energy is stored in the rotation of the wheel. A bit like when your car coast. The real power is the magnet coil of copper coils of a generator. 2. Very little. But if you did the best configuration real bearing and precession team could get much more. Maybe around 1 / 4 watt. 3.n not even close to the energy required to operate a fan. Perhaps with a new configuration of the precession. So I think it still uses the movement of the pump to recharge a battery. Then run the Battery fan after pumping a few times. More like portable radios engine.
