I didn't think the J-damper had been banned, Mclaren came up with the idea then Renault didn't quite understand how it worked and came up with the mass damper which was banned.

Yup, he speaks the truth. I read up on it a bit just a second ago, and that's exactly what happened. I couldn't find anything about Mclaren's Double Breaking System too...I'm guessing that it must have been very hush-hush.

The story I heard was that Mika had crashed out or the car broken down and after he got out the car some photographer stuck his camera into the cockpit and took a photo that showed a 3rd pedal. Some other teams that I think were already suspicious got hold of the photo and complained. I'm not sure if it was illegal at the time or not or if it was banned after the discovery.

I don't know but I have always put it down to 2 reasons. Both are just conjecture

1, to create some airflow through the cockpit
2, decreases drag somehow

Its what bud said, just ventilation for the driver. Jarno Trulli said one time that at some tracks like Malaysia, the air that comes through the vent is still hot and it feels like blowing hot air in your face from a hair dryer.

Finding this site really good if it can answer any questions

I think the mechanical KERS uses a cvt (continuously variable transmission) to connect the flywheel to the drive instead of through a clutch.
I'm not really sure how the electric one works but I thought it would be some type of thermocouple that converted the heat from the braking into electric current which is then stored in the battery, then used to drive some sort of electric motor connected to the drive.

I seem to remember CVT being mentioned now come to think of it.

Not sure how you would convert heat into electricity, apart from maybe a Steam boiler type of expansion that would run a generator, does not sound very feasible. If you where gonna go down that route maybe attaching it to an the exhaust could be better. TBH I never really thought about it being a heat derived energy before.

KERS and how it works was always a google search away

Can someone post of a list of all 20 drivers and their car number?

It can be done with this:
http://en.wikipedia.org/wiki/Thermocouple

That's what I assumed it would be since they often talked about re-using the energy from the heat from braking but from looking around it looks the electrical F1 KERS system will use some sort of combined dynamo/motor to regain and re-use the energy.

hmm interesting. I always thought a thermocoupler changed its resistance, and did not produce electricity. According to that link the maximum voltage produced is at 70uV/C or 0.00007V/C if F1 brakes run at 1000C, that would be 0.07V it would produce at maximum brake temp. 70mV might not get you that far.

Heh, yep you're right,there are high power thermocouples though and they can be added together but you might still struggle to get the power required depending on the size and output of each one.

Whats the thrust of a F1 car?


.....wait nevermind.

[headless]

what are the little oval shaped holes in the nosecones of F1 cars for? I've been wondering this since about 1997!

Toilet releif reasons
