Another experiment that I did while I was in Middle school was, trying to power a motor with another motor and light bulb. The idea was jump start a motor belt to another motor that can generate power back to the other motor power it and with extra power to light up a light bulb, well I did this because I was stubborn to understand “you cannot get free lunch” in this case, basically you cannot produce more energy from another source of energy, well I did the experiment anyway.
Picture below. As you can see two motors, both have permanent magnet motors. So what I was put a belt from motor A to motor B, jump start motor A that would turn motor B to generate electricity, as you can see it does generate power, but when I connect the power to motor A it stopped, so the experiment fail. But, I was able to generate electricity to power a light bulb and some other small electronic devices that doesn’t use a lot of power like a digital watch… I this is a good test, it can be use as concept for future alternative energy, clean energy that is.
Similar experiment that I did was with solar cell, the idea again is to get the solar cell power up a light bulb and use that light bulb as light source for the solar cell to produce power, well, it failed again. No such thing as “free lunch”
