Wind powered car

The hybrid is kind of neat around town but on the highway the straight drive will win every time.

Hydrogen is not all it is being touted to be either. It takes tanks four times as large as that used by gasoline to hold the same energy.

Tax Rebates to subsidize Japanese auto industry while the American industries go bankrupt not to mention the ridiculous trade deficit!!

I think you are misunderstanding. I haven't seen anything about the fan driving air through the radiator, only that positioning a fan there would block air from flowing through the radiator (to some extent).

Yeah, I just got a bit confused at the arguments. Using fans there in comparison to one on the roof.

Anyway, the point is that if air movement is used to generate electricity, no matter where the fan is, under the hood or on top, it will require additional energy from some source. That would be whatever is used to power the vehicle. The the energy would be in proportion to the amount of electricity generated.

Ol' Newton again requiring all energy in the system be constant.

How about the P51's radiator? The radiator was in a scoop on the bottom of the airframe with a ramp exhausting the heated air rearward. The heated air provided more than enough thrust to offset the drag of the cross-section of the scoop.

I had this argument a couple of weeks ago. It seems that some (Ford) have designed the engine so it has less torque at the low end, relying on the electrics for the start-up. They can then get away with a smaller engine (less low-end torque, anyway) than the equivalent straight-drive car, saving fuel on the highway too.

It's not as dangerous as the nay-sayers believe either. The problem with hydrogen is availability.

US car manufacturers can build hybrids too. ...not that I'm in favor of these subsidies.

You're too full of yourself (****, iow) to see humor, Harry... Besides.. The guy asked about powering an 'electric car,' did he not?.....

Good point...I'm an old P51 fan....used to go see them yearly at the Watsonville Fly In....They flew support back in WWII and will always be remembered by the fantastic roar of their engines.......not to mention their great contribution to the war effort....hope all is well. Keith....Ross

It was a form of jet propulsion. The Meredith Effect. As I recall it only becomes effective at higher speeds like 300 MPH.

Hardly "full of myself" Just correcting some very confused understandings of the laws of thermo and physics.
