    I am new here and have been thinking a long time about infinite power and movement, so here is my question:

    If you put a lamp against multible mirrors with all the mirrors aiming at a solar panel, will it be enough to power the lamp again and
    even get more power out of it?

    Ps: i am not english so my grammar is not the best.

    No, you won't even get the same energy back, because some energy is lost at each and every step, usually as heat.

    Mirrors don't create energy, so having 10 mirrors around a candle is not the same as having 10 candles. The very best you can do is collect all of the energy of that one candle and direct it to a solar panel. Then the solar panel will convert less than 100% of that incident candlelight into electricity (a typical value today is between 10 and 20%).

    And of course, real mirrors are themselves imperfect, so not 100% of the candle's energy will be directed to the solar panel, so you can't even break even. You will only lose.

    That's the tough lesson of the second law of thermodynamics, also known as the "no free lunch" principle.

    Lamps generate both a light source and a heat source. From memory (I might be completely wrong) but the ratio is about 90/10 for heat and light (efficiency) . The heat is due to the resistance in the bulb which creates the light. Even if you were to try and harness the heat as well as the light energy, you would still lose power due to dissapation of the heat
