spinner, it is presumed to be electric driven using the fans to power it and or to recharge the batteries.

spinner ..there is more than one vehicle that has proven to save us money and to use wind and solar , lets roll with it
or at least look into it.

it takes crazy things like this to think outside of the box.  there's no dumb ideas, because it can cause someone to think about something that they never would have without watch this video..  go electric............

Someone mentioned somewhere a problem arising with stop & go traffic, well....

why not add an air compressor to the system that would be charged up with regular driving of the vehicle.  Once in deadly slow traffic, you switch over to the air drive which will then give you the little bumps of movement you need to get through traffic.

Yeah I know, you'd need a huge air tank if you were stuck on the freeway in LA, but hey, just a thought.

The fans not turning in stop and go traffic wouldn't matter too much, because the motor isn't "idling" like a gasoline one would. However to eliminate the possibly of running low, a solar panel would do the trick in the daytime.

this is the dumbest thing i have ever seen out of all the dumb things this is the dumbest
the pinwheels will provide more losses in air resistance than u can gain with charging

maybe u should drive your hybrid car with the brakes on all the time because then the regenerative braking will recharge the battery!

and the video showing the model car moving by the fan blowing the fan is providing the energy it shows nothing except that it is almost as stupid as the other one

Here is the deal ...

Unfortuneately Pese is right ... The more drag the more power you need to move it...

But there is a design which I have thought of a couple of years ago ... With wind...

Anytime you are slowing down it does not matter how much drag you use because your objective is to come to a stop.

Now the tesla roadster uses this in the wheels or axel when breaking they generate energy...

A similar design could be done with wind!

How you ask the answer is simple in all the doors and the front bumper you could have tubes with fans in them that open as soon as the breaks are depressed and close as soon as you step on the gas again. This would generate free power for your car  ...

The maximal efficiantcy that one can get while slowing to a stop  is the maximal additional energy that you can recieve other then the heat losses that you could conserve using the electric motor.

Solar Paint and solar sun roofing or windows would be another way to make your car more efficiant as well.

But yes the amount of drag placed on this design is equal to the amount of energy gained if not less energy.

SOLAR

Car makers are in the news today, especially
General Motors.

The company appears to be on the verge of running
out of money. It's likely to go bankrupt without
government intervention.

Apparently, two million jobs are tied in one
way or another to GM. Not only that, but countless
billions of dollars in bonds too

One of the ideas is to give GM money for "innovation."

The truth is there's been a lot of innovation in
car making in the last ten years.

The only problem is none of it has shown up on
the production floor. Why the disconnect?

Here's what one man working with high school
students accomplished:

i had this website a while ago that detailed a solar/wind van made by a guy in the UK

http://www.speedace.info/solar_van.htm

Quote
UK road tax is free!!!  Yes, electric vehicles have to have an excise licence, but it's issued for free.

At the very bottom you also have the list of all the worldwide solar team wich make a nice list of comparative pieces to adapt a normal car to the road , a mix of solar . wind tunneling and braking regeneration is totally possible and probably wouldnt cost that much .

I think the dumbest thing one can do, is make a statement as though it is fact, even though it is merely an opinion. Especially a negative one. YOU my friend are DUMB beyond compare. 8)

Here is the REAL deal....

There is something called momentum. There are also things called hills. I could make positive assumptions all day. But until I KNOW for sure I will assume(by opinion) this thing can put energy back into the batteries. Until you come up with real tested(by you) documentation, I will retain my assumptions.

when one base himself on physic laws, the only assumption he make are :
he didn't forgot one, or more, of them in his calculations.
or that he did took into account the special cases, where/when they apply.

The assumption, I can see now, is that this is supposed to be over unity. This is in the electric car forum. That does not imply over unity. All this idea needs to do here is increase milage substantially to be relevant here.

my point is that you can calculate the results without making a bunches of assomptions.
the only assomption you will make at the end is that you didn't forgot anything.

momentum mean the the energy level will stay at same level unless an external force is apply, positively or negatively.
so.
momentum = momentum energy
momentum + drag = need more energy to keep the same velocity.
momentum + drag + hill = depends on the hill angle and the drag, whitch is in function of the velocity.
if drag energy > hill energy then it = still need energy = difference of both energies.
since you still need energy, you won't be able to store any energy back without losing velocity.
like you can see here, what might work in some cases might not work all the time.

the wind drag is in direct relation to the energy used to stay at a fixed velocity.
that mean that for something to work like in the video of reply #13
the natural earth wind blow must always come from the front for it to work.
the wind generated by the fan in that video is not the same as the wind drag on a car.
the wind drag is caused by the velocity of the car, it is not something that happen for free, energy is needed to fight it back.

you don't have to beleive me.
all the force at play can be calculated.
even for the methods used to harness the energy back.
ex: regenerative bracking efficientcy > wind generator efficientcy.

and since the efficientcy of a wind generator is so low, it might not even give enough energy back to fight it own surface drag.

i think the only important factor is,.. can it get you from point A to point B without costing 26 cents per mile?
