Video Notes:
This video is part of a series here
• Discussing Free Energy

The clip I show at the beginning is from this video but there are at least 50-100 just like it by others.

The video that started this conversation 👉 • Reviewing Free Energy ...

How to size motors for projects 👉 • How To Size Electric M...
👉 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 ... 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.
Technical corrections
None so far.

@wds4097
@wds4097 Рік тому
@Richard Autenzio If you look at the Dyno charts of an electric motor, you’ll find that voltage will always be about level (give or take about 10% between 0RPM and the max RPM), but the drawn amperage will climb from a low baseline linearly up until it reaches between 3500 - 4000RPM, then it’ll begin coming back down at a decelerating pace, but the RPM will keep increasing. Basically, to get an electric motor to accelerate from 0 to around 4000 RPM takes a lot of power, but getting it from there to 8000 - 10,000 RPM takes less and less power. In much the same way it takes much more effort to pull a heavy cart from a dead stop to keeping it rolling once it has some inertia, an electric motor takes less energy to maintain or even reach higher speeds than it does to get it up to a lower critical speed. This is why cruising in an electric car at 40 - 50+ mph is much more efficient than trying to drive in the city, even with a similar amount of slowing down and accelerating (say +/- 10mph every few minutes).

Tbf the teachers are constrained by time they have to teach the students the basics. Different students have different level of passion for knowledge based on their upbringing. Therefore the depth of the topic needs to be explored by the students themselves in their own time. Their interest for the knowledge can be increased more if their surrounding is constructed to be towards practical use of knowledge which made them see its usefulness in daily life.

I served on US Navy Submarines in the early 60’s both diesel and Nuclear boats. I was a Navy trained reactor operator when on Nuclear boats. In the fall of 1963, moored in New London CT there were a lot of anti-nuclear folks that on week ends and holidays would harass us by water skiing as close to our boats as possible yelling obscenities. It’s just like today but 60 years ago and it wasn’t just a few, there were many. Often I was standing topside watch with another mate, both of us armed with Remington 1911 .45’s. We tired of it over time and concocted a plan. Back then our boats had four sanitary tanks each capable of holding 1,500 gallons of human waste and they were blown with compressed air into the Thames River by the below decks watch during their 4-8 AM watch. Can’t do this today but it was different back then. I told the below decks watch to not blow these tanks to the river until I told them. When these guys on water skis came by we blew them into the Thames river right into their skiing path and they were skiing in our excrement. It personally made me feel better. I won’t tolerate bad behavior in a man. We are still seeing it today though.

if it wouldnt extend the range then why are hybrids a proven point that this works? bro said thats why they dont put alternators in them already, but they do, all the brands. it also puts a load on the engine but somehow it extends the range. you dont need all that torque just cuz u wanna go go 0-60 in 2 seconds. accelerating that fast is inefficient in itself. he thinks the electric motor is gonna use more power because of a load, but thats not how it works, the alternator steals energy from the already overpowered motor, extending its range by making it not as powerful. he literally explained it in the gears comparison. half the weight capacity for double the speed, or double the weight and half the speed. its the same concept why electric trucks r gonna require bigger/more motors to haul alot of weight. same concept why a v8 gets less mileage than a 4 cylinder. if you were to limit the v8 to only use 4 cylinders, it would also extend the mileage. thats exactly how regen braking works

It was only when it started to get dark at work leaving time in late October that he found his own proof. He rode a motor bike to and from work and when he was leaving he started the bike and let it tick over as he put his helmet on. He then put the lights on and heard the engine slow down, switched them off and the revs picked up again. The next day he came in and told us he had never even thought about the lights using fuel as being significant.

But the Company survives and offers the technology to other manufacturers (They have onboard already Scania Trucks and others) But I really wonder what has happened in the background to make them back down.

Yes, great explanations but that still doesn't answer the BIG question I have in mind. That question is: "Then how do you explain why they even put/use alternators in gas powered cars!? They find it worth it. Why? And why, at least for electric accessories like a car AM/FM radio, wouldn't it be worth it for electric cars as well (with only the way the same basic type of vehicle is powered being different)?"
@krystoffersprague6100
@krystoffersprague6100 Рік тому
electric motors use next to no power to turn motors, ever see how small the battery is to turn the motor on a hybrid? not much bigger than a battery for a Power Wheels kids car and the crank amps arent as high. With traditional motors they need spark, unless it's a diesel, to ignite the fuel which can't happen without a big amp battery. If you make a lot of stops and have to start and stop the motor it puts a strain on the battery and it eventually dies. That's where alternators come in, while it may not be effective with multiple motor stop/start cycles-nor will the starter motor last as long- it prolongs the life of the battery until it's internal design is wore out. Most V8s need 750-1000 crank amps or CA. CCA is cold crank amps which comes in play for regions where it gets close to freezing obviously and that's why it's also listed on the battery. When the starter motor is powered by the battery using 12v it uses a small motor and gear assembly with a Bendix actuator and wound magnet to push that little gear to mesh with the HUGE flywheel...little gear moving a huge gear that mechanically turns the vehicle motor until fuel takes over. The time before fuel takes over, which also type of fuel, age of motor, efficiency, etc come into play before it takes over uses a lot of power and this being amps. the alternator is designed to take some of the motor power to replenish the battery close to capacity as long as the system is complete and the battery can accept it. Corrosion will inhibit and make that system work very hard and destroy it over time. Bigger motors need bigger alternators and higher CA capacity batteries because of the little gear to big flywheel ratio like he used in the video, it's a trade off. But in the end it's only as good as the parts and how well they're maintained, much like our bodies 👍

@@kevine9376 true but it's taking too much power that the electric vehicle can better use to go further, based upon the video presentation. Now maybe if different ratio gears were used to the alternator and is took less revs to generate more current but with a bigger amp system it could compensate but again most electric batteries are massive. Even if it was a tickle, it'd still take more energy to attempt that tickle than to go further...unless breakthroughs in tech allow it to happen. It could be hidden purposely though.....

I agree that he has a talent for explaining the subject, but I disagree that this is a complex subject. It's a lot like buying something with sales tax. Sales tax representing the waste energy. You have $10, you want to buy a $1, and there's 10% sales tax, so it's going to cost you a total of $1.10. Now you have $8.90, not $10. Then for plugging the alternator into the battery to charge it, you haven't opened the soda and want to return it. Well there's a 10% restocking fee. So you're only going to get back $1.10 minus the 10% restocking fee, which ends up being $0.11. So now you've spent $1.10 and gotten back $0.99. So instead of starting with $10 and having $10 despite returning the soda, now you're 11 cents short, so you have $9.89. You've lost money just by trying to get your money back for an unused product. Keep doing that, keep buying and returning the soda because we're talking about an engine running an alternator, every moment of time it loses energy, so to extend the analogy to this, you have to be constantly buying and returning the soda every nanosecond. Before you know it, you're out of money. So the motor is going to grind to a halt.

A science teacher interested in real science? Is this real? I Would really like to know how to calculate how much is lost in each conversion of chemically generated (or would that be converted from what its stored in? Like gas, coal, nuclear?) required to get the energy generated/converted so much more efficiently than could ever be done in the engins under the hood of my car before its finally the electrical energy stored in batteries in an electric car being generated/converted into the mechanical energy required to turn the wheels of that car. So many steps must result in massive loss. From stepping (transforming?) It to high voltage, or even dc to transmit it from the power plant miles away where it is somehow magically created with ZERO emissions, Then converted to lower voltage & back from DC to ac at my city's substation so it can fit in my citys lines to be carried close to my home where it must be transformed to yet lower voltage before into my smart meter, then into the car charger Newsome was just a couple of weeks ago was telling everyone not to use because we had a couple of warm afternoons , & pg&e shuts off the power every time the wind blows & the grid can't provide what's needed now , Because those who have now made gasoline illegal in a couple years (Right about the time Claus has declared we will own nothing. But none of all this is related, of course) they had a duty(an important word to define) to qt least maintain the grid, & If they are going to make laws requiring 5 TIMES the current load (pun not intended) on the grid they had a DUTY to ensure they improve the grid accordingly. & the people have a duty to hold them accountable for being derilect! But I digress. So 240vac entered into the home & must be converted to 12 vdc (=LOSS yet again. Is that the 13th loss now? Ive loss track.) to go into the batteries, to be converted into chemical energy to be stored in those batteries where it must be converted back from chemical to electric energy before it can be converted to mechanical energy to turn the wheels. If only ten conversions/transformations (& rhere are far more) & you "only" lose 10% each time.... when fact is more like 30% loss...must be converted be used

The fuel you burn in your car has also gone through a series of conversions and transportation in order to become gasoline in your tank. It has to be extracted, transported to a refinery, refined, transported to storage, put in a delivery truck, added to a storage tank at your local gas station, and then dispensed into your tank. Each of those also takes energy (particularly the refinery bit, but the transport bits can also be pretty costly). Then your gasoline engine is about 20-35% efficient at turning the energy stored in the gasoline into motion. In order to compare that with electricity, you have to really look at the exact source of electricity. Taking natural gas, the extraction process is about as energy intensive as oil extraction, but it doesn't need refining, and converting it to electricity is about 45-57% efficient. From there transporting electricity happens over wires and while it is not lossless, it involves far less loss than trucking liquids. Once it is in your car (charging is another loss, but in the 5% range or less), the car itself is pretty close to 100% efficient at turning the electricity into motion. Of course, there are some losses for heating when it's very cold out, but the gasoline car is better at that only because there is so much waste heat it can be "thrown away" into the cabin - an electric car only has a fraction of those losses when it needs to produce heat. Electricity can also come from many sources, as electric cars don't care how their power was created - it's all electricity. So you can burn coal, burn natural gas, generate it with solar, tidal, nuclear, wind, or any one of a number of sources. So you can use the source that makes sense locally to generate electricity. "& pg&e shuts off the power every time the wind blows & the grid can't provide what's needed now ," Electric vehicles can (in large part) be charged at times when the demand is lowest and the supply is highest. Other electric uses have a more difficult time moving. So EVs can provide demand when the grid has excess supply (in most places this is at night when businesses are shut down, but in areas with a lot of solar power this can actually be during the day when solar plants are cranking out power). Most if not all EVs can easily be programmed to only charge when demand is low - and if you set electric prices appropriately (Time of Use plans) your EV drivers are going to be the portion of your demand that is the most easily-moved.

We spent a week of lunchtime breaks investigating why until I finally got the fact that energy is a constant and can not be created or destroyed.

I’m not an engineer so I’ll ask my dumb question. Say you build a light weight alternator that didn’t take a lot of torque to turn. Could you turn it sideways and add a pinwheel on the end of the shaft, then have a wind funnel on the car so it charges when you drive 35 MPH or faster? Obviously this isn’t going to do away with the need to charge but if you build one into each side of the car with intakes and one on the roof it might in theory be able to drastically extend the time needed between charges right? I work in green energy so I was just trying to think outside the box and can’t find an obvious downside to this. What do you think?

@Dustin Bridges The main issue, if you were to do this, would be the added drag from the wind generator/ wind turbine. Especially, for an EV, drag has a huge effect on their efficiency. I haven't done the math on this but I am willing to bet that the increase in air resistance, turning the fan, would out way the energy generated. The only time it would generate more energy than the car is using is when it's going downhill but by that point, you should just use the motors driving the wheels as generators which all EVs do use (regen braking). Hope this answers your question :)

May I ask if that is the engineering job you wanted? Or did you have other fields of engineering you were interested in? I always wonder what people want to do with mechanical engineering and have a hard time myself figuring out what I'd want.

You're an amazing teacher. I wish all teachers were as patient and demonstrative as you were in this video. I've had many teachers who only delve into theory and formulae rather than providing demonstrations for students to learn from. It's the teachers that take the time to design such demonstrations and to explain exactly what's going on that I've learned the most from.

Unexpected analogy, but I loved hearing the splash every time the power shifted. Bonus points for addressing regenerative braking. Great video!

I first read of regenerative braking in a very early copy of Mother Earth. It was a hydraulic based system. At the time I thought that the author had not allowed the added weight of needed pumps and such. A few years ago driving a nephews Tesla S for the first time, I was shocked at coming up 20 feet short at my first stop sign due to for the regenerative braking.

Using the cups with water was a great visual, really helps visualize and explain the process in simple terms that pretty much anyone can understand. Really wish I had teachers like this when I was in school. Then I might have actually paid attention. Thanks for sharing. Edit: One thing people should take away from this, is that if it were this simple. It would be common place on every EV. I had a coworker say they should put turbines on EVs to help recharge the battery while driving.
