    I disagree with your premise. The theft, and defense of life, liberty and property happen at the point of a gun. It is a tool, not a cause. Driving is not a fundamental right of man. Defending ones life is.

    Still think some regulation is acceptable? Okay. then how do you feel about some "reasonable regulation" regarding voting? (perhaps only land owners can vote? Maybe pass a test first or pay a voting tax?) Or "reasonable regulation" for freedom of speech (such as jail time if you offend someone or laws against speaking ill of the government?) Finally, how would you feel about "reasonable regulation" of ones ability to practice a religion (say we just ban Islam completely or require everyone pray to the Official State Government) Doesn't sound very appealing, does it?

    All of those things I've mentioned are considered God-given, fundamental rights which the US Constitution and Bill of Rights prohibits the government from tampering with or infringing upon.

    Besides, who gets to define "reasonable?" This is the definition of a slippery slope. Fundamental rights are immutable, and having politicians determine your rights is precisely the opposite of what our Constitutional Republic was designed for.

    Reasonable Regulation often isn't.

    Excellent observation about cooling! Boyles' law, IIRC. Yeah, A/C may be "free" in this case if they put a heat exchanger at the point where the gas is throttled.

Two steps forward, one step back. Hopefully we won't have to adjust the dwell on the distributor or gap the dynamo.

    >.Since this car would have both an internal combustion engine and a compressed-air engine, I would guess you can get either heating or cooling fairly cheaply.

    Ah, but there's the rub. From what I read, I don't think there is an internal combustion engine. Unlike current gas/electric hybrids which use the gasoline for propulsion, in this case they're simply burning the gasoline (or other fuel) as a source of heat to improve the efficiency of the compressed air charge.

  20. Exactly on 100-MPG Air-Powered Car Headed To US Next Year · · Score: 2, Interesting

    If they're heating the air charge to increase the volume/pressure then I suppose that efficiency would increase as ambient air temperatures decreases, but what does this automobile do to provide passenger cabin heat? If the heat extraction from the burned fuel is efficient (and I imagine it must be) then waste heat is unavailable for the cabin.

    This is one of the substantial (and as yet to date, unsolved) issues for an all-electric car serving in anywhere other than a tropical climate -- at some point you must provide heat to the cabin. Electrical resistance heat is incredibly inefficient, heat pumps are efficient above about 30 degrees F (though they are nearly worthless below that temperature), and further heat pumps have a very low thermal output (e.g. it would take FOREVER to warm a car on a 30 degree F day).

    This car might succeed in Southern California or Florida... maybe texas, but seems impractical for anything other than summer use in the majority of American states. (Even the southwest -- you can die of hypothermia in the desert at night.)

    It's a shame, because I'd love to have some more options for transportation other than gasoline engines.

    (BTW, I never knew about electrically heated VW Beetle seats and I've been restoring them for years. I suspect that's some aftermarket "solution." The Beetles (and all aircooled VWs & Porsches) capture heat from the outside of the exhaust manifolds.)

    I wish them luck for success but I too am feeling skeptical. Here's why:

    >>400-500 miles per 8 gallons, or 50mpg. Pretty goddamn good for a 6-passenger vehicle.
    Yeah, but notice they say "six passenger vehicle" and not "vehicle with six passengers." BIG difference.

    With very low-hp automobiles, the extra weight of even one passenger can have a tremendous impact upon performance and economy. (I drive a 40hp 1964 VW Beetle so I know from whence I speak). Driven alone, my car actually performs as well as most modern cars. Add a couple passengers and suddenly it's sluggish and MPG falls into the mid-20 range.

    >>Say we halve what they claim for most practical uses (city driving), you still have 400-500 miles per 8 gallons, or 50mpg.

    Judging from the tone of the press release (they don't seem to believe it) the 95mpg figure doesn't seem likely at all. And if we take half that figure, 50mpg as you suggest, it's still better than most gasoline vehicles, but roughly on par with turbodiesels. But we need to consider this a bit further. Because low-hp vehicles are greatly impacted by laden weight, if we were to take this 6-passenger vehicle and add a couple passengers I think we'd see that 50mpg figure fall further, possibly into the range of traditional gasoline vehicles which puts it well BELOW that of turbodiesels! It takes approx 35 hp to maintain 60mph in a vehicle with average aerodynamic drag. This vehicle has approx 75hp equivalent. That leaves 40hp to accelerate a vehicle with up to 900 lbs (6x150) of passengers plus the weight of the car. Subtract parasitic losses such as alternator (headlights, heating??) or a/c compressor drag (-5 hp) and it's anemic at best. Meaning it will struggle on hills, and passing on the interstate will be difficult.

    Disappointing, but it helps us realize just how efficient a fuel-injected, turbo intercooled internal combustion engine is.

    Basically, the US was enforcing, finally, the last of an exceedingly long line of UNITED NATIONS demands and the surrender terms from the first Gulf War, which Iraq never fully complied with.

    However, if you're implying that he merely insists on fighting a conflict with a well-armed military, then I think we can agree. However, is that a problem? Is not the goal of armed conflict to win, and the best way to accomplish that is through application of overwhelming force. In short, I don't see the problem here.

    So whichever way, either you're ill informed and/or unable to connect the dots of historical events or you don't understand the purpose of having a military.
