Explain Bedini's free energy machine to me

Tesla... /sigh

Another hallmark of the free energy nutter is a deification of Tesla.

I have seen this upwards of ten times on websites such as this.

You do realize that he did go crazy so it isn't necessarily a deification more than people not mistaking insanity instead of genius.

When you think about Ohm's law as a definition of resistance, then what you find is that for some things, resistance isn't constant as a function of applied voltage, but you can still use that equation to define a resistance for anything, even if that value is only valid under specific conditions. Diodes and transistors are rather important examples of where the resistance defined by Ohm's law is not constant (current can vary exponentially with applied voltage).

Your right but you have to realize that if you ever take the EE class where you learn about Ohm's law it's called linear systems. With linear systems ohm's law always works because ohm's law is just a specialized form of a linear system. Your cars shock absorbers is another example and the math is exactly the same.

Actually, shock absorbers have moderately strong nonlinearities in their response (including hysteresis). Which isn't terribly surprising, given that fluid dynamics are messy.

In the real world approximately nothing is linear. Some things model to it reasonably. Shock absorbers, usually not one. Especially since we design them to be non linear.

For a fun demonstration of this, push down on your car, watch it bounce down and slowly rise up. Compare it to what happens when you try to lift the car up and it rises up on its absorbers. It behaves significantly differently.
