Hi, I was recently reading up on the workings of fluorescent light bulbs, and I thought of an idea for using the bulb as an electrical generator. I know that inside the ballast of the light fixture, there is a small coil of wire that keeps the electrical current from going to fast through the bulb. I also learned that the gas inside the bulb itself, when excited with electrons, turns into plasma, which interacts with the phosphorous coating on the glass to make light. I also learned that unlike normal copper wires, when electricity flows through plasma, the resistance drops as the current rises because the excited ions continually release more electrons as the electricity flows through the gas. I was wondering if anyone knew if both the voltage and the current would rise inside the bulb if the control coil were not present to regulate the power flow. If both the voltage and current rise couldn?t one logically say that the bulb is outputting more power then it took to get it started? If this is true (and it?s purely hypothetical) couldn?t one create a circuit chip to keep the bulb lit and draw out the excess power instead of wasting it away in the control coil? I have absolutely no idea if this would work, but it was just an idea. Any thoughts?
