Okay, Hello everyone! and great thread, idk if its still alive but i felt like signing up and giving my two cents!
id frist like to introduce my self as a 2nd year auto tech student and a 15 year mechanic. i love electronics and have build/created/fabricated just about everything.
a few things i noticed, one stood out, Free energy.
If you figured out how to get free energy, you were either shot, or to smart to patent your idea. so i think that's a dead route. also you wouldn't want to share that sort of technology.
as for fuel efficiency, its a giant scheme, people want fancy cars, not cheap plastic crap cars. Ive owned many cars now only to realize, i want my diesel truck to hual things and i want my saturn to save gas.
a couple of times i have come across better technology. Take for example, the most fuel effienct car in america,
The Geo Metro. three cylinder, XFI. curb weight of 1600lbs, and 5 speed automatic, tuned for weight reduction and modified cam duration. This got me close to 63mpg. but the car was plastic and reallly cold in the winter. i absolutely hated driving the crap ass car. A buddy of mine told me about a friend who modified his Metro with a electric motor and a hydrogen fuel cell. he pushed his car to about 90 mpg. so the idea that yea your ordinary joe can modify a car to reach the 100mpg is possible.
another unique thing i was taught in school was the future and direction of cars. The future for cars is going to be diesel hybrids. think of a diesel generator that powers battery's that power a electric motor of some sort. the principal is based on locomotives. when they throttle up they use a slow process of the engines reaching a certain "optimal rpm" range then maintaining that for extended periods of time. there isnt a throttle pedal in that sort of application. hence the future of cars. if you can understand that.
in my personal experience, there is a whole slew of more efficient engine designs that currently employ higher mpg.
take for example the idea of VARIABLE TIMMING TURBOS or the ford ecoboost technology. the idea of that a turbo takes a min to spool up, why not use a smaller second turbo to spool up the first turbo?
or variable intake runners? A engine needs more air faster at high rpms so short intake runners increase efficiency, where as long runners are great for loads on low acceleration.
Or the idea of direct injection helps atomize fuel better. these technology are already implemented.
now for the stuff that will blow your mind.
Quasiturbine engines, use the same principal of Wankle rotary engines, except they use a 4 chamber design.

wankle motors have less moving components there for more efficient design.

the idea that internal combustion engines havnt changed in the last 100 years just sickens me.
if you have a afternoon check out all these engine alternative.

i like the wave disk generator, same principal as a turbine engine.
anyways i dont claim to be an expert by any means, but theres always a better way of doing something especially when it comes to cars.
