Horizontal wind turbine on vehicle

[Cuicui]

We are talking about putting a wind turbine on the roof of a car

No, not on the roof, but under the hood behind the grille.

Pout...

Either way, it's peanuts to motorize a car. It is only extra, and more.

it doesn't work against tricycles by the sea

you will look at the size of blades you need in full wind.

Uh, if you read on the first page the introduction toiridium who launched the subject, there was never any question of motorizing a car.

certainly and then there, we start to mix everything up because the link to the invented wind-powered tanks works with absolute wind which is an intrinsic source of energy, whereas from the start, iridium tells us that it thinks it is "recovering" from the energy of the air displacement of the vehicle, which I refute.
it is therefore assumed that the "natural" wind is zero.

Good evening
that would give a wind turbine placed and faired horizontally on the roof of a car (blades // on the roof): which would make it turn by depression on the upper surface of the mobile.
not to be confused with autogyro

saw little bit between 10 and 25% energy recover.
is not very weak and is far from being negligible.

we will always be limited to Cx by its forms and therefore as much benefited as much as possible.

Can we know where you get the 25% from?
It depends on the size of your wind turbine ...
And anyway, it will be 25% of power recovered on 30% of additional aerodynamic braking (for example)

I think you still haven't understood the history of the Cx, many of us have explained it to you: the Cx (and also the master-couple S) do not depend solely on the exterior shape of the car, but also of the interior form, in the places where the air passes.
So if you brake an air flow under the hood it's like putting a speedbrake on the roof, it's the same

To join some who explained it to you in a less visual but more scientific way: all energy drawn from the movement of the car FORCED comes from the organ which sets the car in motion, that is to say the engine.
Any recovery of energy while the car is running only draws a little more power from the mill. It's physical, mathematical, universal

The ONLY way to gain energy is not to recover it (= pump again) but to save it, by reducing aerodynamic braking = improving the SCx. Lack of pot, your wind turbine makes it worse ...

are figures out there go that I push you.
It is for that that I repeat from the start that anyone with the necessary knowledge in the field is welcome and also that I insist on seeing how much we can recover from this system

and many times I explained that anyway even if we do not put a wind turbine, the air will still be braked by a solid surface which is the original engine.
the constraints of colission obliges us to have fixed external forms.
the wind turbine brakes the air flow less strongly than the engine itself.
his grave the Cx is can be improved.
more it will leave room in the engine compartment which will allow either to add equipment, or to channel the air for its circulation in the vehicle.

reread the subject from the beginning.
I made it clear that I don't believe in perpetual motion.
and then I was fed up with the bowl of repeating myself.
the air will in any case brake in the engine compartment.
that there is a motor or that there is not.
so take advantage of this lost energy
knowing that even if we add a wind turbine, the braking of the air achieved by this one will be completely negligible compared to the surface to which the air must face in the engine compatriment which luimème is fixed by constraints of colissions ...

It's a bit like installing a fan in front of a parachute.
the braking of the air from the fan will be negligible compared to that of the parachute.
except that the fan provides energy.

The principle is the same.
the air will still be braked so that the wind turbine will be negotiable in front of the rest.
and in addition to its, we must not caricaturalize the thing we lose bcp more energy on the exterior surface of the vehicle and bcp less on the interior surface.
even if it can be considered a mini parachute.

I agree with tlm here practically but the fact is that in reality we have form constraints and therefore Cx at the front of the car.
added a wind turbine in an air flow which is lost anyway because it braked just after will not change the Cx of the whole enormously nor meme the drag.
the batteries will be recharged in proportion to the consumption.
the more energy we need to advance, the more the wind turbine will recharge.
and by negligently modifying the Cx or the drag.

it remains to be seen in what proportion this type of material can recharge the batteries!?!?!?!?
history of knowing if its worth the cost or not.
but if for example we imagine an audi A3 with its large front air intake we can easily imagine a wind turbine of the same surface and deduce a power.
its only a guy who touches his ball in there can say.

who here can assess the power of a wind turbine of this type which can withstand winds of 90km / h or more ?????

Blah blah blah .....

Blah?

Blah blah blah ....

Bla!?!

Blah!

In short, unbeatable!

Iridium, the least of courtesies is to try to understand the answers you get when you ask a question.
If you stubbornly stay on your (wrong) idea, you will not move forward.
A little humility and admitting mistakes is more positive! Take the trouble to reread the many posts of many participants (!!!) or, I repeat, if you are still not convinced: MAKE A PROTO and there you may understand!

I apologize for the "tone" of this message but I have a kind of "allergy" so bad I find a mind wasting its resources in useless research.

Greetings.

PS: the quote from Olivier_22's post on energy is bright, isn't it? Unless the principle of conservation of energy is foreign to you, in this case you are not on the right forum.

[iridium]

MAKE A PROTO and there you may understand!

I started to make prototypes which go in my direction ...

so change your tone or change the subject !!!!

even better prove to me that I was wrong other than telling myself.
"Baaaaah if you add a wind turbine, its will be an additional charge and therefore you will ultimately consume more than before !!! "
its will allow you to avoid wasting your resources other than writing to people like shit.

PS: and do not speak to me any more of politeness because considering the tone used in your message is the hospital which laughs at the charity.

Now I expect proof from you of what you are doing when you don't agree with me!
considering the tone you used is the least of the things expected of you.

[dirk pitt]

it seems to me that highflyaddict has taken gloves to answer you by apologizing in advance for the tone, etc.
on the other hand, your answer ....

explanations have been given to you but you don't seem to have explored them. when I say explore, it means taking the time to consult other sources, documenting and trying to understand why what you have just imagined does not already exist, etc.
good luck anyway.
