I believe you are right with you'r numbers.Which it why Smokey's engine used ceramic coatings on the pistons.What is being ignored here though is the ammount of unburned hydrocarbons leaving the engine,which is the main reason for catalytic converters.And if I remember correctly,wasn't a mostly ceramic engine actually built and tested back in 82?Increased thermal effiency requires lower tempratures to achieve the same overall effiency.There is more then just thermodynamics involved.If I remember correctly,Smokey's engine reached a maximum coolant temprature of something like 140 degrees F.
But I guess I'm wasteing my time here because the currant known laws of physics are infallible now.All the past misconceptions in physics have now been discovered and corrected.All science is now perfect.And there are NEVER more then one set of equasions to be considered to solving a problem.And it's also known that increased efficiency doesn't supply more usable power that can be better utiliesed with higher gearing resulting in lower engine rpm's,resulting in less fuel being used.You don't have to have increased heat to be able to better utilize the heat being generated.I agree with the general laws of thermodynamics,which I have studied on several occasions over the last 25 years.But I don't agree with all the assumptions made concerning those laws.No I can neither prove nor disprove them.But some of those conclusions don't seem to make sense when all factors are taken into consideration.



But this is where I quit.Everyone now knows all know laws are absolutly perfect.Mankind has become infallible in his sciences.It is impossible to build an affordable engine that can better utilise the fuels being used.It's impossible to use more of the fuel entering the combustion chambers,and decrease the ammount of unburned hydrocarbons in any kind of practical application.And all mathamatical theories concerning this have now been proven by practical application of those former theories.Opps,I guess that hasn't been done yet.But the experts know their theories must be 100% correct.I don't claim to be an expert on anything.Which is why I always try to learn more.And I already admitted my numbers may be off some.But my origional points remain that most,if not all the mileage boosting gadgets advertiesed are junk technolodgy.And science is not perfect.And secrets are kept from the worlds population about better technologies every day.But it seems I'm the only one here who is guessing the technology that can greatly increase fuel effiency is being kept secret until the auto manufacturers feel they can make the greatest profits due to demand for super efficient cars.And any manufacturer looking to get their car on the market before general consensus agrees the maximum profit potential has been reached,would be ruined,discredited,and bankrupted just like the Tucker car company was for building his vastly superior car.The tucker automobile was decades ahead of the compitition.Even though they could build cars just as good,they didn't want to because they didn't see a potential for maximum profits for safer and more efficient cars.You believe what you want to.Keeping technolegy from the public has been done before.And science facts have been supressed before to keep the public ignorant of the potential bennifits.And no,I'm not a conspiricy kook.I'm just an inquiring mind who has had access to some little known technology,and questions what are the real reasons past and preasent for supressing new knowledge.But you just keep on believing that you've been told the truth,the whole truth,and nothing but the truth.I have nothing more to say.
