There's no reason even a big SUV shouldn't be able to exceed 35MPG.
Yes, there is. There's only a certain amount of energy per gallon of gas. And it takes a certain amount of energy to move 4,000 lbs of metal. Even with a hybrid system, I doubt you'll see many SUVs like an Expedition or a Suburban get close to 35MPG. The Ford Escape hits 34MPG I believe, but it also is a fairly small SUV compared to others.
Agreed. Composites are the way to go (look at SpaceShipOne and the 777 Dreamliner). They're strong and light. The problem is they can't be recycled well. So make sure when you build a composite car, that it's going to last for quite a long time.
As cars move to electric drivetrains (a la Tesla Roadster), maintenance requirements are going to plummet due to a reduced number of moving parts. Also, the transmission is much simpler (two gears, fast and faster).
what of the users who did lose valuable computer time due to this problem? The proverbial kid handing in their homework (or dissertation paper or whatever), for example. Apologizing and willing to pay for a third party tech support service (e.g. Geek Squad) is nice and all, but does that cover damages incurred? doubtful. Perhaps that EULA will finally get a test.
Almost never will damages be covered. Come to think of it, I think in this case I can say "Damages will never be covered." You have to show value and proof of destruction of that value. Your homework being destroyed? Your dissertation being destroyed? While it may have a large amount of value to you, monetarily it has very little value.
If your commodity hardware is distributed properly, you don't need six sigma uptime on it. The system handles the redundancy. For more info, google for info on Google's distributed architecture.

A typical patch from Microsoft takes years, if you're a consumer.
Fixed that for you.
If Windows was running somewhere with high visibility and intense needs like the NYSE, Microsoft would have the problem fixed extremely quickly.

When the shuttle enters the atmosphere, the brunt of the heat is on the underside of the orbiter. The thermo protection tiles are facedown, so the plasma or ionization layer is open at the trailing end behind the shuttle, providing a hole through which communications with the shuttle can be maintained with the TDRS. Even if the TDRS satellites had been in use when Mercury, Gemini and Apollo were in flight, the spacecrafts still may have experienced blackouts because of their body shapes.
and
NASA found that if the radio signal was sent back up to the satellite and then down to the ground, they didn't even need to try to communicate through the plasma layer.
I saw in a TIME Magazine article that another contributing factor to air travel delay is the fact that planes can't fly in a straight line. They can't fly straight from Boston to Washington DC, even. They have to fly between control and radio towers most of the time, so it's more like a jagged line to stay within the different control tower's radii. How they travel oversees, I do not know. I am willing to be enlightened by anyone who does know about this, in addition to an article about the flying-between-control towers procedure.
Correct. They have to travel in victor airways, which are designated "highways in the skys". Airplanes also have minimum seperation guidelines in these airways. Because of this, even though there's tons of sky out there, the system has limits.
ADS-B, the next generation FAA tracking system, is supposed to fix this. All planes will have transponders on them that transmit their position to a network that bounces it back to every other plane and controller within 150-200 miles. Planes will save fuel and time being able to fly direct to their destination. UPS already is using it at their base of operations for all their aircraft (helps on the tarmac with juggling planes around). The problem is that to retrofit the existing system is going to take 10 years and tens billions of dollars. It'll be fixed sometime, just don't hold your breath.
The big upcoming shift to electric drivetrains and storage systems for cars is going to be huge though. No dependency on oil, no source restriction on where you get your energy (wind, solar, nuclear, etc.), and extremely reliable components (no need for oil changes, 2 gear transmission, and so on).
Hopefully John D Anderson will write some articles on the subject when Wikipedia reaches the stage where experts can be verfied and peer-audited (as to make the information more reliable, so it could be cited in academia).
While in its air-superiority configuration, the F-22 carries its weapons internally, though it is not limited to this option. The wings are capable of supporting four detachable hardpoints. Each hardpoint is theoretically capable of handling 5,000 lb of ordnance. However, use of external stores greatly compromises the F-22's stealth, and has a detrimental effect on maneuverability, speed, and range. As many as two of these hardpoints are "plumbed", allowing the usage of external fuel tanks. The hardpoints are detachable in flight allowing the fighter to regain its stealth once these external stores are exhausted. Currently, there is research being conducted to develop a stealth ordnance pod and hardpoints for it. Such a pod would comprise a stealth shape and carry its weapons internally, then would split open when launching a missile or dropping a bomb. Both the pod and hardpoints could be detached when no longer needed. This system would allow the F-22 to carry its maximum ordnance load while remaining stealthy, albeit at a loss of maneuverability. However, there is concern over this program as external carriage of fuel tanks has shown more stress placed on the wings than originally anticipated.
The SR-71 engines were hybrids. Turbofans for subsonic, ram engines for supersonic. What we really need is a breakthrough in engine technology where the engine has components for all phases of flight while still being reliable and efficient. Turbofan/ramjet/scramjet engine anyone?
What happens when you launch ordinance off a missile rail at supersonic speeds? Does the ordinance continue at supersonic speeds for a short period and then slow down past the sound barrier?
Plus jet fuel is way different than your car's ordinary gasoline.
It depends. A lot of new GA aircraft are coming out with diesel engines that can burn either automotive diesel or Jet-A (jet fuel). There's a big push to move away from 100LL, which is used by the vast majority of piston planes on the US, because it contains lead (there's also the fact that they only make 300 million gallons a year of it, which is chump change to most oil refineries).
Good sir! Since you're an EVE, and I'm an EE in training, I was wondering if you could answer a quick question for me. Would using a capacitor of significant size inline with a traction pack on a hybrid allow the motor to draw more current for short bursts without putting strain on the traction battery from heavy drain?

I owe those fellows at Tesla Motors a pint for building such a fine care. Two pints a piece if they get my car to me before the end of '08.
There is no such thing as a "consumer" OS, only the situation the OS is put into.

When you drip fuel on the tarmac since your fuel tank joints haven't expanded fully yet, you'll have that =)
