## Sleep deprived brain fart...Solar Panel Lightbox Generator

OK first off let me tell you I don't know much at all about solar panels, wiring, or electrical at all. So to those that want to flame save your breath. Now at 3:30 am my time I woke up and since I couldn't sleep logged on to Instructables because something was bothering me. The something that wouldn't allow me to get back to the sleep which I craved was the idea for a Solar Panel Lightbox Generator. Now I see the logic in thinking about some of the perpetual motion generators and how they are impossible. And I believe my idea is not possible either, but till I get some info from someone that knows more about electric and solar panels I don't think I will be able to rest. So here is the idea, someone please explain how my thinking is wrong. Build a box of solar panels faceing inward with a light source inside of the box. once the panels start to charge a battery, use the battery to power the light. First off I know direct sunlight is optimal for the panels, but I'm thinking "outside/Inside" the box. How much light does it take for a panel to actually start creating current? How much energy does the light use to create the light? How do you measure how much light (candle power?) a bulb/LED or what ever produces and is it enough to " power " a solar panel/cell? My thinking is if a LED/incandescent/haligion light can produce enough light, with the right amount of solar cells it could power its self after start up. I know things degrade, bulbs burn out and all that. What I guess I'm saying is mathematically could this happen? Since I know so very little about solar and electrical in general is it possible? And if it's possible could more panels be added to make more power than it uses? There's my brain fart, feel free to point out the flaws so I can get some sleep tonight.

Solar panels & LEDs aren't 100% efficient, you lose some energy in each. If they were you might get unity, but no more. You're right on "I believe my idea is not possible" but anyone who answers technical on this is most likely going to Google your keywords (do that) L
