Could this help with saving in our mpg?

I was thinking, there is a technology with puts our engines into "sleep mode" the way our computers can be without having them shut down.
Places like when you stop at a light and such.
It is supposed to benefit in our mpg pretty decently.
Now with that in mind why cant they incorporate that into the rx8?
Even if it only provides and extra mpg or 2 its still great.
Incorporate that with other ideas like hydrogen, solar paneling on the wing and roof of the car and such, and you will see some really improved #'s

Thoughts?

many hybrids already do this, they shut down the gas engine at idle and use battery power for the aux systems. when you accelerate it starts with the electric motor first then kicks in the gas engine.

even mild hybrids do this such as the chevy silverado pickup. The main reason fo needing a hybrid is that without the engine, there is nothing to drive the A/C, stereo, lights, etc....

They already incorporated this technology in the car. You engage it by putting the key in the OFF position at red lights.

U waste more gas shutting off and startng an engine back up, this temp keeps it in a type of sleep mode.

To answer the other question I read it in a newspaper article sometime last fall.
If I had a link I def would have provided it.

As far as the solar panels go, whats the diff between making the top of the wings surafce and roof out of solar panels and not?
It wont make the car look riced out or anything, and im sure it can be made durable, its not like the front end of the car which is subject to rocks and such.

if I can find an article online ill post it.

I remember reading somewhere lately (can't remember if in C&D or on one of the forums) that in places where gas is 2x what it is here, many people already do shut their cars off at stoplights.

How am I wrong, all this article talked about was if you are waiting for some1 and u know it will take awhile liek 15 mins.
Thats common sense.
I was reffering to things like stops lights which are around 1 min or less.
You dont stop at a stop light for mins mins. You will waste alot of gas if you turn your engine off at every stop late and turn it back on.
I remember reading that, doing that was the equivilant of 1-2 mins of engine idling.

Just so you guys know, when brillo and I played with the fuel mixture on his RX-8 through the Megasquirt, we found that the way the car is right now is just about as lean as it will idle at. Richening it up actually made it idle smoother. The only way to usably go leaner at idle would be to shut it off.

i read somewhere that starting up the car puts a few miles worth of wear on the engine.

The biggest eason why startup is so hard on engines is because when your car is sitting for a while most of the oil flows out of it and down into the pan. When you start it up you might have some metal/metal contact in spots which creates wear. When the oil is doing it's job, there is no metal/metal contact.

this idle-stop technology is already pretty extensively used in Japan. Buses, taxis, trucks/rigs... nothing new.

I wonder what a rotary-electric hybrid would be like...

Wouldn't this be bad for our plugs and cause our cars to flood when cold?
