👉 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?

A solar panel would give you "some" energy. But it would also make the car more expensive and heavier. In fact many car companies have tried this and went bankrupt because it cost so much for so little return. Check out this video.    • Why aren't solar cars everywhere?   It still has to pass a crash test for road worthiness, and buyers may not be willing to pay 3 times as much for a car that only get 1% more miles. I made those numbers up only to illustrate the point. "Current" solar panels don't produce enough energy per sqft to offset the difficulty and cost of adding them to cars. Not yet. It is great for a house because the surface area is huge and houses don't move. Cars park in garages, under trees, and/or may be behind a building or even a big truck in the parking lot all day getting no sun. Millions of engineers are thinking about this problem. No one has given up on making better systems. We are all looking for 5-10% more efficiency that doesn't raise the overall cost too much. Its just the problem is more complicated than this.

👉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.

FYI I do in fact talk about regenerative braking in the video! LOL There is a whole segment on it. Thank you for watching!

The hardest part of building a perpetual motion machine is figuring out where to hide the batteries.

When I was 5 I had a light on my bike powered by a generator. It was like riding with the brakes on. When I was 5 I knew you were right. Great explanation TY.

You are a great teacher Jeremy. You use facts and proof through logic and science. I'm happy your children are lucky enough to have you as a teacher. Great job teaching your own children and making it fun.

Jeremy, I WAS one of those who thought about alternator on electric car. I’m so glad I watched this. You taught a 64 years old man something today. Love your channel

Best explanation of why an alternator isn't a free energy machine. I've tried to tell someone this but i am not a good talker like this guy.

As a teenager some 60 years ago I had a bicycle with a wheel-driven dynamo that powered the lights. It was noticeable just how much harder it was to cycle the bike when the lights were switched on.

You sir are an amazing teacher and father! My dad took the time to teach me so many things when I was growing up and I still appreciate it each and every time I accomplish something with the knowledge he passed along. Knowing this makes me really appreciate that you take the time to do these things with your children and pass your knowledge along to your viewers in an easily understandable format. Thank you!

Man the education system could use more people like you. None of my teachers ever explained things with even half the passion and enthusiasm you do.

Where were you when I was in school?? I always learned better with visual explanations then numbers on a chalkboard. All thought I already knew this, the way you show and explain things I would have done far better in school in the 80's. Iv have learned a lot more in my late 40's then i ever did when I was in school. Thank you for being such a good teacher and God Bless!

There is not a car manufacturer in the world who would not jump at the smell of improved efficiency. There are teams of dedicated engineers looking for these incremental improvements every day. If the alternator scheme worked, every manufacturer would have implemented already. The explanation in this video was excellent. Good job Jeremy, good job...

You have a talent to teach. I'm an old man having served on Nuclear Submarines as a reactor operator 1962-1966. I am very qualified to make this statement Sir. You have a talent to teach. Please keep it up. BWV

I absolutely love how well you conveyed the transfer of energy between such seemingly alien systems. I have a BS in engineering, however, while I was in high school I could not wrap my head around gears, teeth, size ratios, and efficency transfers. Watching this, I truly wish I could have had these kinds of videos available. I have such appreciation for people who take the time to explain, in such a concise manner, things like equivalent exchange. Hope to see more videos like this as opposed to others trying to disprove the earth is round.
