A follow-up to my Nikola Tesla Video. Can you extend the range? What if you add gears and flywheels? These questions answered in the video! #tesla, #freeenergy, #generator

Video Notes:
This video is part of a series here
The clip I show at the beginning is from this video but there are at least 50-100 just like it by others.
👉 Frequently asked questions in the comments.
👉Can you capture the wind energy of the car at highway speeds with a windmill or air ducks etc?
The short answer is no.
Exactly like the alternator, the windmill acts like a brake resisting turning and slowing down the car.
Remember you are "creating the wind" with your motor. It’s not free. If you add a windmill or scoop or "x", it will produce more drag and slow the car. you need more power from the motor to keep your speed. The power needed to spin the windmill will be slightly more than the electrical power created by turning it.
You have to use more energy than you can make like paying $50 to get $28.
👉Why not add solar panels to the roof, hood etc to use the suns energy?
👉What if you add a second battery charging one as you drive on the other then switch. If you re-watch the segment where I use the cups to show the flow of power, you will see an example of why this doesn't work. You are literally just charging one battery with the other when the process is boiled down to where the energy went. To simplify, it flows from battery #1 to motor, then motor to wheels, then wheels to alternator, then alternator to battery two. The problem is each mechanism is wasting some power, and because the second battery is a load just like the alternator, you are also running the first battery down faster by some amount that is greater than the energy that goes into battery two. The important thing is the power out of battery one is more than the power needed to just drive the car. It is driving power +charging power! You will get more mileage without this system, and that is why no one uses it. This is very easy to test with a remote control car, an extra DC motor to act as a generator, batteries and a multimeter at home.
👉What if you attach an alternator directly to the wheel instead of the motor?
This concept is addressed several times in the video. Perhaps you skipped around or didn't understand. Watching again should help. Short answer. This is exactly the same problem. Attached to the wheel IS attached to the motor. Even if you disconnect the motor after getting up to speed (because you just want to capture the kinetic "motion" of the car) the alternator acts like a brake quickly slowing the car down. In fact that is what regenerative braking is. The motor acts like an alternator slowing the car down and charging the battery a little. This is covered in the video. Cars already do this (regenerative braking), so adding an alternator doesn't add any benefit. It's just another part that can fail and increases the weight of the car.
Technical corrections
None so far.
