I've try it 2n3055 transistors too. Led is a good source, good volts. A simply solar cell only produces 0.5 volts. Very interesting, is possible use 100 LEDS in series and put capacitor discharger to recharge batteries.
Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma — which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.
