"The biggest wind potential lies off the nation's Atlantic coast, which the Interior report estimates could produce 1,000 gigawatts of electricity..."...when the wind's blowing.
Bullshit, there is always wind somewhere, if a windmill is down, another one will be the backup.
And thats before you get into power transmission issues - windy sites generally arn't near big cities.
Do you often see nuclear power plants inside a city ? We are perfectly able to transport electricity over hundreds or thousands of kilometres... (with some loss, but it is definitely doable)
Feet, miles and knot based units are the de facto standard in aerospace. The scientists
use SI units, the pilots do not. For a software I wrote I had to use SI units internally
and had to convert those values to feet/miles/knot based ones before passing them into a
pilot specific software. I work in germany (at the DLR if it matters).
Pilots don't use metric units but engineers do, I work in France (for Thales Alenia Space) and the most unmetric unit i've seen is the millimetre...
Once again: my buddy got shot by one of those high velocity armour piercing rounds; it went straight through him, hardly any damage at all. So there's no chance at all anyone'd be hurt by one of those namby-pamby pistol rounds. They'd probably bounce right off or something.
Did he also get shot at billions of times per second for 4.5 billion years?
Unfortunately for NASA, this is the reason most people would want to get rid of NASA, because it would be many thousands of times more cost efficient to develop those things directly for utilitarian Earth bound industries rather than having indirect spin-offs through NASA. What a waste:(
In that case, why didn't anyone develop any of this stuff before NASA ?
Surely the asteroid has considerable inertia due to its mass? A probe would have to apply thrust to overcome gravity wells that it encounters. The asteroid will be affected by the "drag" of passing close to large bodies but already has considerable ineria.
Let's say that I sent a ping pong ball, a house brick, and a 20t lump of iron heading away from earth at 5 m/s. I would expect the ping pong ball to slow most quickly, followed by the house brick. In some situations, the lump of iron might be able to escape where the others would not. You'd experience the same effect if you tried to stop a car rolling down hill a ten miles per hour and then compared it to stopping a skate board moving at the same speed. Perhaps I'm missing something?
Yes, you're missing the basics of physics... This whole post is pretty much bullshit.
slashdot doesn't even need to store comments. They could just randomly generate some "frosty piss!!", some "brown rope", some "kdawson is a retard", and some "dupe!" posts.
They don't apply for a power plant... you don't care about gyroscopic effects...
No? Current human energy consumption averages around 15 terawatts. Say you want your wind energy system to store on average at least a day's worth of energy. That makes 10^18 joules. I'll leave it to someone else to carry the calculation further, but when it comes to potential for irreparable climate change, I'd much rather take my chances adding CO2 to the atmosphere than storing 10^18 joules of energy in angular momentum along the earth's surface.
Put two flywheels rotating in opposite directions, problem solved...

But water is apparently a highly explosive substance that can be used to bring a plane down.
It isn't known exactly how this might be carried out, but apparently it was discussed on some Islamic internet site.
Na ?
I don't like Bush either, but eating the guy? Isn't that a bit too much? And no I didn't follow the link, why do you ask?
And btw, it's spelled "recherche", not "récherche"
Finally! Now, can someone do something about the hair on my palms?
Yes.
Don't talk out of your ass, the win95 upgrade CD allows you to do a clean install if you show it a win3.1 floppy...
Et vive l'UTF8!

You're spelling is correct
How ironic...

And do you keep them both in the same closet? :-(
In the closet? My drives are out and proud, you insensitive clod!
And as for the term "climate change" ... that is, well, dumb. The climate is always changing ... always has, always will.
"climate change" stands for "anthropogenic climate change" but four syllables words are too hard to remember for americans...
I'd go for #3 of course, it has the highest number after its name !
Actually we don't, biologists understand evolution better than physicists understand gravity...
Is that Klingon ?

I remember that flywheels were considered for electric cars as well.
Some of the issues I remember off hand were:
1. Specialized materials needed to build flywheels that are small, yet heavy enough to keep spinning for a long enough time after being "charged"
2. Getting the energy IN the flywheels in the first place - it takes more energy to get them spinning than what you draw from them.
3. Given the high velocities - what will happen when they fly apart? Also, the gyroscopic effects they generate while spinning.
4. The heavy mounts needed to safely position them negated any advantages through increased weight.
I don't know if any of these apply to stationary flywheels built into power plants though...
They don't apply for a power plant:
