Ok....heres the deal mate Work = Force x distance

In a car jack, you crank the damn jack like a gazzillion times to get the 10 inches off the ground. Those cranks turn a gear which travels the distance. You need to do the same amount of work to lift the car whether with a jack or with your bare hands. With a jack, what you do is make the distance longer, hence reducing the amount of force you need to put in. Pulleys operate on the same principle.

Question at hand,

Nope....impossible under the current laws of physics. While yes, a device with a smaller amount of energy can trigger a reaction that produces larger amounts of energy (daily example, car battery produces power to crank engine, which then starts combustion cycle to produce enough energy to move the car)

no sh1t sherlock, ever checked what currents are induced on the up-side?

Yes, it is fundamentally impossible. But most of our methods of producing energy give the "impression" that we are creating larger amounts of energy from smaller ones. A casual observer would contend that energy is being "created" in devices such as engines etc, when actually it is just conversion

You bold the wrong section la sis. I said IMPRESSION, big emphasis on that. And I'm referring to ppl with little or no scientific background at all
