Introduction: Free Energy From Rgb Leds Serially

8 rgb leds (common cathode) serially, sun, meter..... outputs 7 volts dc.
rgb led like solar cells...... it works. :) face up the sun and tilt it 35-40 degrees.

by the way, has anyone tested whether the same effect occurs with power LEDs? eg
2 high power 10 watts LEDS in parallel 11 volts and 900 mA = equal 11 volts and 1800 mA
or
2 high power 5 watts LEDS in parallel 7 volts and 700 mA = equal 7 volts and 1400 mA

this is the first step of something great.
i know, only 20 mA current, but it will be improved.
1 rgb led 1 euro/unit. but will be cheaper in a near future.
please I would like to hear ideas for improving the amperage.
thanks for watching. god bless you all.

you can try using a black marker to color the bottom of the LED so that it attracts more light. Bye and good luck

pretty expensive though. LED's tend not to generate very much current at all, but this is an excellent demonstration of how you can use an LED as a light sensor as well.
