as far as i know this cannot be done, but i havnt heard or seen on the internet to say that this can or cannot be done. soo.... my idea is to use solar cells on a bank of LED's. in theory, when there is light energy on the solar cells, that power is stored in a capacitor (capacitors?) and then through a resistor, and then into the LED bank. they would then produce enough light energy to power the solar cells, and charge the capacitor(s), and so on. this would be started by 2 LED's powered by a cell battery, then turned off when enough energy is built up in the capacitor(s). i understand the theory that the LED's will produce heat as well and burning off the power....but.... if the LED's are sealed in a vacuum, and heat cannot go anywhere, and the resistors are only allowing enough energy to go through and power the LED's, and the capacitor(s) are storing enough energy to power the LED's...can this work???? can anyone build a working model to show this cant work???? ????
