Unfortunately, MS didn't "kill" IE, they've just completed it's total integration into the OS. W(When I say OS, I probably mean Explorer or it's future equivalent) It was already difficult to work around since it was embedded somewhat into Windows. I think the lawsuits caused them to pause; but, I suspect this may have been part of the plan all along. Now, the OS (Explorer) and MS apps will automatically handle html, xml, etc. without calling up a special browser app...
Actually, the physics for this doesn't work out. If you figure that the average SUV (my pickup truck for example) has an upper surface area of 7 meters square. Also, the angle of the surface is not ideal wrt the sun. Typical solar cells are less than 10% efficient; but, for argument sakes we'll bump this number up to 15%. This gives you a maximum energy intake of about 1.6 kW which is only 2.2 hp. Battery storage would allow for some additional peak capacity; but, could hardly offset the requirements for modern cars or allow night operations.
Even at 100% efficiency (which is impossible), you're only talking about 10.5 kW or 14 hp.
You forgot, I believe, OS/2 and VM/CMS. although, they may no longer be available (?) I'm sure someone somewhere is still running such machines (They just don't die...)
IAAP (but not a PhD), you need something to ionize for an ion engine to work. In a vacuum, there's nothing to ionize. Ion engines in satellites use Xenon or something equiv. as the "fuel"
It's called a Laser...
The navy's been funding free electron laser (FEL) research for about a decade now; and, it's hitting the MW range. It wouldn't be too much of a leap to push it high enough for weapons use.
There is nothing to prevent you, as an individual, from owning your own nuclear power plant. Of course, the cost of implementing such a thing, and proving it meets all the safety requirements, and providing the necessary documentation to the NRC and DOE, and following up with regular inspections, not to mention the cost of the fuel, might prove prohibitive to an individual.
Having said that, I'm not critical of the regulations because they're there for a reason! It's not like owning a car; the results from an error in judgement can be much more significant: God forbid Bubba should forget to check the fluid level in his back yard reactor, cause a meltdown and nukes his entire neighborhood.
Virginia Tech generates it's own electricity using a university owned power plant with a system of boiler, which by design, can run on whatever is the cheapest fuel available at the time (coal, oil, gas, biomass, etc) They also use the steam from these boilers to heat the campus. I'm sure they're concerned about energy usage since they see a direct effect on their fuel bills...
Even if this were true, you're forgetting two things: first, you can fuse atoms other than tritium and deuterium (albeit they're among the easiest). Second, if energy is essentially free, then we can mine the vast stores of material available from other sources like, the sun, Jupiter, Saturn, asteroids, and so on.
If we run out with that kind of reserve resource available, we deserve to have fire taken away!
This has been discussed in sci-fi. It could in fact cause warming of the eco system if energy were free and used on a massive scale. There would be ways of dealing with it -- reduce the Earth's albedo and therefore it's natural heat absorbtion. Add reflectors in orbit that block sunlight. Beam energy away from Earth (pulling heat out of the eco-system). Move the Earth further from the Sun (which may need to be done anyway). Build a shell around the Earth (a la Ring World). and so on.
I'm not saying I agree with their premise; however, your argument has a hole in it: you say The variation just wouldn't be that great given the fact that the solar system simply hasn't moved very far in 100 years.
Well, that may be true; but, in the past 100 years there have been numerous distant super-nova. In the past 5 years, new emissions have been seen from the black hole at our galactic core, indicating that it may be becoming active again.
What I'm trying to say, is that it's not necessary that we move into a different region; but, that the cosmic "weather" in our region may have changed. Of course, that's assuming they're right, which, I don't think they are.
We're not even 100% certain there is a global warming problem. There are geological records that indicates the Earth regularly goes through not only major ice ages and warmer periods, but also mini ice ages and warm periods as the global temperature oscillates. As it happens, we're in the middle of a warm period... Remember our weather data only goes back 100 years of so, plus some anecdotal evidence...
do a yahoo search on the financial status of the CEO, etc. of SCO. because they're insiders, it's public record. Many of them have stock set to sell once the price reaches some value...
Don't buy SCO right now... You're wasting your money. sit back and wait until IBM beats them down a little in court. Their stock value will drop significantly. That's the time to buy!
water is non-conductive. It's all the contaminants in the water that make it conductive. By processing the water you can create "De-Ionized" water that is *gasp* non-conductive.
Yes, early VW's used magnesium, for cost reasons, and when it caught fire (due to either overheating or fuel leak) it was nearly impossible to put out. The magnesium reacts with the water under those conditions to produce more oxygen and hydrogen and more fire... The only way to put out an early VW engine fire was to use a grade D fire extinguisher.
From a computer mechanic / automotive mechanic (past lives) / physicist: The green colored radiator coolant is usually a mix of ethylene glycol, propylene glycol, detergent, and various corrosion prevention chemicals. The low-tox versions remove the ethylene glycol (it's poisonous)
Silent? maybe you don't need the little high rpm fan on the processor; but, you still end up listening to the fan on the radiator and the pump motor...
Your best bet is something like one of those Zallman coolers -- they only make 20dB of noise (less than the 30dB NEC stated)
I've used a laptop as a data acquisition test platform. For that you need as much horsepower as possible -- and in the smallest size you can reasonably get. (read that as, you may need to lug it up and down 4 flights of stairs inside an industrial complex, sometimes with limited access).
In the process they destroyed a good set of RCC panels from Atlantis. They'll have to be replaced. That's probably a big chunk of that $3.4M dollars...
there are better articles at other sources. The short answer to your question is yes. Oh, and, NO, this isn't the same kind of soft foam used in padding; it's a hard, dense, polyurethane foam
They performed several tests. One problem is that, from the footage they have, they can only come up with an estimated range of angles -- not a specific number.
In one test they used a fiberglass components from the test glider Enterprise. This was more or less done to prove the test setup was correct; and, to prove that the foam would cause some (unknown) damage. Follow up tests with real RCC panels were required for verification
In another test they used actual panels taken off of Discovery -- this was more of a glancing blow and clearly cracked the RCC components. Would components with similar cracks have survived an actual re-entry? We may never know; although it's reported Discovery did return from one of it's prior flights with a significant crack in a RCC panel.
The final test used actual panels from Atlantis and was a more direct hit. As you have seen, it punched a BIG hole in the leading edge. This is bad, very very bad.

As long as the shark has a multi-mega watt nuclear reactor strapped to it as well, we can do it!

You build a big reflector that sits between the sun and the Earth. You did say that energy was free didn't you?
