How to build super-efficient Chevy's

I sent this to FORD and GM, so they have been told. This proves they want our fuel consumption to stay they way it is!

How do you build such a car? The fact of the matter is that internal combustion cars are only about 25% thermally efficient. 75% of the heat energy goes into the radiator. That is a terrible waste. How would a car company use this energy more efficiently?

1)External combustion
a)Using a modern flash boiler system means that a larger boiler carrying many gallons of water is not needed.

I. Modern mono-tube boilers need only about 3-5 gallons of water. Only a small percentage of this is actaul steam. They are less likely to explode as they use less volatile fuels. Modern steam generators for automotive use are constructed in such a way that in case of a rupture they have vary little water at the saturation point, preventing an explosion.

II.The boiler could pick up as much as 1200 degrees of heat coming off the exhaust manifold. That would be more than 800 lbs of pressure. Very useful

III. The boiler could be wrapped by the exhaust header(s) soaking up the heat and help catalytic converter light-off by being heated up by use of a electric element.

IV. If a steam engine is used in combination with a diesal the transmission could be deleted or switched to a centrifugal clutch allowing direct drive. Direct drive and lock up clutching allow for better fuel economy and less weight which helps economy also.


The engine without a transmission could sit low and back for excellent handling. If combined further with an electric motor the gasoline engine could be throttled back to the point that it merely generates heat and the air/fuel ratio is leaned out quite a bit further improving economy. Another idea is to include a small transmission. And have each component able to couple/decouple. That would allow a electric motor to drive the car until the batteries where depleted

What sports cars have better gas mileage and more performance than the new Corvette C6 and C6 Z06?

The new Corvette Z06 has a hand-built V-8 that weighs 71 pounds less than BMW's new 500 hp V-10. The new Z06 is the only car sold in North America that has more than 400 hp that doesn't have a gas guzzler tax. The new Z06 also gets around 26 mpg on the highway. The new Corvette C6 has 400 and also doesn't have a gas guzzler tax.

I appreciate your devotion to such a great car, but gasonline engines are only 25% efficient. What I'm talking about is 60% or more efficiency. Your Z06 would get more like 50 mpg and have enough torque to roast 20 inch drag slicks. The future is now, not in an engine that is over 100 years old.

as cool as it sounds. im not sure. i mean that would be cool if they could use the heat and turn it into electricity so i dont have to run an alternator (which will free up power). or even a steam asisted drive that would be cool too. but i think that the tech is also there for us to naturally get 50 mpg. but if they ever come out with a concept, ill be glad to see it.

umm... you meant the steam engine was over 100 years old right? the old school chevy small block has only been around for 50 years, let alone the new engines they put in todays domestics... besides, wouldnt a steam powered car have to stop quite often to fill up on water? it would be great for all those small towns that used to be water towers for stream engines on railroads lol. if you ever get bored, notice on a map how they are all 7 something miles apart lol...
besides, you would need something to create the heat needed to boil the water, so a gasolene engine would be necessary and who knows how big of one you would need to heat it... prolly not that big, but still...

but i think that there might be a way to tie it in for something. it has potential, however, we wont know until we have a MODERN concept. but as people say even if we use all the oil, then we can get it from corn, sugar, and so on.

I promise you GM is looking at alternative fuels and of which have more efficiency than steam.

what is gm doin for thier motors there gmtech? im curious. ive been thinkin about this in some of my spare time and i wonder if we can harness natural gas (which is more abundant then oil) into a decently runnable fuel source. ive seen certain small engine designs that, ussually 2 stroke, that use it.

i also wonder about the motor designs themselves. for instance is twin cam a more efficient set up... for instance the early dsm's the 1.8's were origionally seen as the better n/a set up, because of the weight the 2.0 had too much weight for the extra power. (i know its not gm but it's an example, i own 2 fords so ussually im more up on them... but i still like some gm stuff)
there are also other set up designs i wonder about.

it makes me wonder how certain motors as well can make such great mpg.... but these modern ones arent... like mt grandfathers corollas. they got 45 mpg, no prob, my old laser (1.8) got 50 mpg w/ 2 octane boosters. and yet our new aveo (granted its an auto) only gets about 32. and some more modern dont even touch that. can anyone tell me why? i mean if we have the tech for huge mpg( granted at the expense of power) then why dont we employ it?
