Electric car

Hello. So the following scheme of the electric car. Battery 12v (suppose 130 A). I attach a 2kW inverter to it (a current converter from 12 to 220v). From the inverter, I feed a 220 V electric motor, say 1.5 kW. With the help of pulleys and belts, this engine is connected to the drive axle and in parallel with a 700 W tractor generator. The generator accordingly charges the battery. That is, I suggested that such an electric car will pull itself and at the same time charge its own energy source. And now the question! )) Who thinks what about this design ???

The battery 1.5kw el leading motor will not be charged. + 1.0kw when the generator load is 700w, the generator will be considered as 1.0kw in general the battery will not charge

We had 8-10 classes, now 9-11.

We also have from the sixth. And the law of conservation of energy, including the main conclusions from it, was studied in the first year. If now physics is from the seventh grade, I correct the address: "March to the seventh grade, to study physics!".

First, physics is taught in schools from the seventh grade.

This is very bad ... We had it from the sixth ... If not from the fifth, even ... And we studied it, and did not pass ...

I wrote somewhere about the perpetual motion machine ???

Don't you even know what a perpetual motion machine is ???? "Excellent physicists" do not know this ???
Well, I’ll explain this as well. "Perpetuum mobile" is a system with an efficiency of more than 100%. This, that is, an electric car, which, not only that rides, but also is able to charge itself ...

Thank you all for your ability to scoop everything))))


Well then scum it? If physics is "excellent", then .... No wonder I asked, or is it not a joke ...
Simply, if in physics it is “satisfactory”, then this is enough to understand what efficiency is (Coefficient of Efficiency). And that EVEN it cannot be 100%. (That would be a MIRACLE!). Something else needs to be "explained in detail" ???? ...
Well, I’m chewing for those who have no higher than two in physics:
Imagine that the EFFICIENCY of ALL SYSTEM ELEMENTS = 100% (This is a miracle, as I already said !!! They would give the Nobel! For there are no engines and generators in which nothing is rubbed and nothing is heated). So, this means that the generator takes away exactly as much energy from the motor as it produces !!! Not more!! (That is, he will be able to offset the costs of himself !!!). Question: why is it needed ???)))) That is why I advised him to drop it ...))))
But in real life there is no one hundred efficiency ... Let's assume that it is 80% for each element (This is unprecedentedly high for the average one. The same battery "eats" when charging much more than it gives ...)))) .
So, the battery gives up energy. After converting to 220, it remains 80% (Why I advised to find a 12-volt motor)))). The generator takes it from the motor (which also ate “its interest)))), takes another 20% and gives the rest to the battery (which, when charging, also eats its legitimate 20%.
So, through simple calculations, we see that even if the WHEELS are EXCLUDED, and only “Battery-converter-motor-generator-battery” works, then only “100% -80% -64% -51.2 will return to the battery %
This is how your generator will not add, but eat energy ...
Any questions? Or does physics still need to be taught sometimes ??? )))))
So be so kind as to follow the brooms.)

And here I’ll answer in your own language: you follow your broom, you jerk !!! Talking to adults! And if you ask stupid questions, then what are you waiting for ??? To praise ???

Eugene, if I offended you, please apologize. I, as though not a great specialist, but here everything is so obvious.

But, if I'm wrong, then write me why?
To put it more delicately, you cannot get more energy than you spend, any technical (and not only) device cannot have an efficiency of more than 100%! Your battery will always give more than receive, sorry ...

First, physics is taught in schools from the seventh grade. Secondly, I’m excellent at the school physics course. Thirdly, how to write comments of such a plan can be normal, popularly explained!

Yes ... And after all, the evidence was compelling, remember?
- And what evidence? -
- I'm alive!!!!
P.S. This is my favorite movie ... Literally, every minute - quote !!!

Did you really ask a question, or is it a joke?
What jokes, everything is very serious, because Munchausen pulled himself by the hair! smile

The author, I'm sorry ... Have you really asked a question, or is it a joke?
Simply, if it’s real, I’ll say that for some, very short time, he will go. Then it will be necessary to remove and charge the battery.
Tip: discard the tractor generator - then, without it, it will take longer!)))
Council number 2. Find a 12 volt motor. (With the proper approach, you can use the same generator))). Then even more is enough.

Who thinks about this design ???
Everyone thinks that it’s time for the author to go to school, that’s the sixth grade.
