Carrying a spare tire = funny!

Glad I took those college physics courses about energy balance. 100mpg carbeuretors etc. are pretty well covered by applying "Intro to Physics" and mass-balance or energy-balance equations. Can't get something for nothing. Also can't change from one form of energy to another without an energy cost. This applies to changes in storage unit (gas to hydrogen, coal to electricity) or changes in form (heat to motion). There is always an efficiency factor, and it's always less than 100%.

This also applies to DRLs, LED lighting, etc. ALL that energy is generated by the gas in the tank. Little savings do add up, and EPA regs are important. Butt dyno my @$$, it's only the EPA dyno that matters!

As for the socio/political/conspiracy side of things, maybe we watch too much TV, or perhaps too little "good" TV.

Fuel for the fire:
1. Hydrogen will never be a "great" fuel because it takes more energy to extract/refine/generate ("make") it than you get back in the form of energy (motion or heat). No tailpipe emissions, yes, but plenty of emissions, and energy loss, during the "make" process.

2. Ethanol: Ditto, by the time you add up all the fossil fuel energy used to till, plant, harvest, distill... and there isn't enough left to run our infrastructure.

3. Electric cars: ditto ditto. They're definitely not pollution-free, as that electrical energy is generated somewhere, primarily from fossil fuel, and some is lost to resistance as it travels to the automobile recharging station.

4. Toyota Prius's (all hybrids) are powered 100% by gasoline - even when the gas motor is off. Exception: "plug-in" hybrids - see point 3 above.

I said I wasn't coming back, but you can't buy entertainment like this thread!

 

now is that caliberated to a big *** or a huge ***? cause
EPA dyno numbers are great but does not reflect real world data...
meaning, you have to have someone from the suburbs in the car
with a big or gigantic *** to know the true meaning of why mpg
is important to us.

is it... best mpg with a powerful car?
or is it best mpg with slooow inferior car?
or is it best mpg for the best compromise?

continue on! this is only Chapter1. there are 11 chapters
to this book.

 

Matt. not quite true. They use the FULL energy of the 55w bulb.

DRLs work by switching the halogen bulb on/off thousands of times/sec giving that duller look.

Bi-xenons, at least in some comes, mean the low beam is ALWAYS on ... making it much brighter and quicker to kill the bulb.

 

yah, my hand hurts after a few minutes...

 

Hey, thanks for actually reading my post. What I should have said is that 99% of the gasoline is burned in the combustion process. If the 100 mile per gal carb allowed 100 percent of the fuel to be burned, the increase in gas mileage would be almost non-existent. Overall engine efficiency is a lot less, like you said.

 

What I meant was the EPA test, while unrealistic to real-world driving experiences, is the yardstick by which the automakers' CAFE calculations are done... so that's what they're concerned with...
