Kite rotor to power lamp (LEDs)

How to make a Savonius wind rotor using kite technics.
The rotor generates electricity to power a lamp with LEDs.
The lamp lights up from a windspeed of 1.5 m/s , 3 knots
or 3.3 mph.

Now that is a neat little turbine. Why haven't I seen it on the market? Would be perfect for camping and im sure it could push a larger pma.

@sirtom68 Thanks for your kind reaction.The rotor is not on the market, it is just a prototype to show the possibilities of kite materials for this type of rotor. I am now working on a new prototype with a higher yield by doing windtunnel experiments.

Hi !

Great vid.

What kind of generator you used?

[RIENK62]

Hi, thanks for your nice response! A small permanent magnet DC motor is used as generator, produced by Maxon Motor. It is an older type, comparable with the current F 2140 series ( 6 Watt) and provided with a small gearbox ( 1:18). The red lamp ( 18 leds ) is working upto 5 m/s (18 km/h or 11 mph) . From that windspeed on you need to insert a resistor in the electrical circuit to protect the leds from burning out : 90 ohm upto 9 m/s/20mph. If you want to load a battery use the RE 40 / 150 Watt.

5 stars! I see LEDs on trailing edges of the vanes sequenced to make a barber pole effect by POV circuits like those used on bike wheels. What a light show! It could be powered and sequenced through slip rings and cammed contacts, armatures etc as well. The width and # of stripes could morph as well as color, speed, direction (CW vs CCW). POV, animation, strobe and marquee effects are unlimited in their combinations. LEDs need only minimal contacts for switching and are instant off/on.

Hallo Rienk,

Indrukwekkend! En heel inventief. Mijn respect!
