Traditional air conditioning systems account for up to 5 percent of a vehicle's fuel use. Delphi Automotive says it can cut that fuel consumption with an electronically controlled compressor that can adjust its displacement to meet the varying needs of the powertrain and the passenger compartment.

The average driver spends about $2000 a year on gasoline, so doubling milege saves over $1000 a year. It does not cost more than a couple thousand to make a car light enough to get 54.5 mpg. I had a Fiat 850 in the 1960s that got 40 mpg back then, and it was fun to drive. I had an MG 1100 back then that got 35 mpg and was fun to drive. I drove a Nash Metropolitan that got 35 mpg back then, and was fun to drive. It is not that hard to get getter mileage than we do. I can buy a VW Polo that gets 70 mpg right now in Europe, and it costs only $14k. Europe has stricter emission standards than we do.
Wouldn't you like to rephrase your statement: "There is no one making money off promoting global warming, and there is no major cost associated with minimizing it, because the main goal is conservation, and by saving oil, that saves money."?
You don't seriously believe that striving for 54.5 MPG isn't costing far more than the amount of oil/money it's going to save, do you? Perhaps you are aware of some manufacturers who'll back you up on that?
There used to be minerals from human CO2 sources that mitigated, but not after catalytic converters. Now car exhaust is "bright" pollution that causes much more global warming than the smog of the past did.

The scientific community has explored past climate change cycles, and we are supposed to be already into the part of the cycle that is getting colder, not warmer. We have tracked solar output, and know that is not the cause.
But I agree that the reduction of O2 is a significant problem that should be getting more attention.
I'm not so sure that's wrong. Human driven CO2 is also accompanied by minerals that absorb it, and plant life requires CO2 regardless of origin. So little is agreed upon as to the net benefit or liability of or even what constitutes 'excessive' levels of CO2, that it borders on economically insane to throw so much money at this 'problem' without better understanding more of the factors and ramifications of such measures. For example, I don't believe we're applying nearly enough attention to the corresponding - coincidental or not - depletion of oxygen levels, which we and all animal life are dependent on.
I'd much prefer to see the scientific community push back more against the players who have jumped to premature conclusions in order to drive their agenda of global control and ownership of the populace of the planet. I don't know how they got away with minimizing the factors of the Sun and natural climate cycles for so long, but that has greatly skewed 'the science'. So few seem to give consideration to the very real possibility that CO2 increases were DRIVEN by warming rather than driving it. As complex as their modeling was, it didn't come close to replicating the complexity of the organism itself.
Many fundamental principles of science have been violated during all the 'debate', especially evident in the scorn and demonization of dissenting opinion. Dissent must be dealt with in a respectful manner by all sides or credibility will always be in question.
TLuxon, sorry, but you are wrong to believe a volcano is more significant than human pollution. That is because although a volcano will produce more CO2, it also produces raw minerals that absorb more CO2 than they produce. Then when you also consider the particulate cooling, they counteract global warming, not add to it. In fact, one of the proposed solutions to global warming is to deliberately cause more volcanoes.
When will it be made part of the system that both the engine and the AC will shut off if the vehicle has not moved for... oh, say three minutes.
The idiots I see sitting outside the drive-in burger/ice cream joint in their nice AC'd Lexus with the windows up and the engine running... and the outside weather is delicious. And they're the ones who carp the loudest about fuel costs and pollution.
The rail lines in LA running from the port to the rail yards close to downtown were "trenched". It relieved a lot of congestion and accidents caused by long container trains having to use grade crossings, and also reduced the need to move containers by truck from the port to the rail yards: http://en.wikipedia.org/wiki/Alameda_Corridor
But, there will always be a need for trucks between distribution centers and the local supermarket, Walmart, etc. There will probably be a lot of resistance to building rail yards and distribution centers in suburban communities.
I'm all for living as efficiently and environmentally congruent as possible, but all this effort and expense to reduce our production of pollution is completely negated by one moderately-sized volcano.
No, this is an elaborate sideshow to further weaken the little guy and usher us under the umbrella of totalitarianism when we - out of desparation - not only welcome but demand it.
Raising the bus voltage to 42 VDC will reduce wire harness metal by 2/3 rds. Using more efficient devices will reduce the wire weight even more. Using LED lighting which is current mode rather than voltage mode will reduce the need for branch circuit protection shortening all of the wiring for lighting, again reducing wire weight.
I recently noticed that our express transit buses not only use LEDs for all marker lights, they now use them for headlights as well. If nothing else, this reduces the amount of service replacements (costs that a fleet manager is sensitive to) while increasing safety and fuel economy somewhat.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
