Boiling water by releasing some sort of potential energy is the most efficient way of producing electricity.
Wind and solar are not reliable enough for baseload generation as they depend on the wind to be blowing or the sun to be shining at a given time, which is not a guarantee. Geothermal and hydro depend on very specific geography/geology, which does not exist everywhere and in enough quantity for our baseload needs.
The only reliable and economical sources of energy for general baseload power generation not tied to a specific and limited locale will be transportable materials containing potential energy that can be made to release that energy at will. Currently, that means combustible materials or fissile materials.
I believe that part of man rating includes astronaut survival and recovery at any point between T-0 and orbit in the case of catastrophic rocket failure. IIRC, the reason they couldn't just drop an Orion capsule on top of the current Delta IV is that rocket's flight path includes a window where if the rocket were to explode at that point the capsule would not be recoverable even with a perfectly functioning escape tower. I believe it is because the Max Q of the Delta IV's flight path is too great, even though the G forces might still be in line with crew comfort.
Of course, crew survivability means the shuttle would never have been man-rated, as it doesn't contain any crew escape mechanism, which resulted in the death of 7 astronauts when a rocket failed on launch in 1986.

Congress doesn't really care about 'shuttle derived technologies' and costs are a straw man. But ATK in particular, who makes the shuttle SRBs, holds some pretty strong sway over certain congress-critters. That's why the Ares 1 first stage was just a scaled up shuttle SRB even though SRBs are a pretty dumb idea for a human-carrying rocket and completely idiotic as the sole first stage, as they can't be effectively throttled or shut off after being lit.
I don't know if I'm just feeding the troll here, but some control is necessary. Do a little research, and read up on the concepts of the Tragedy of the Commons and the Tyranny of the Majority. When everybody is allowed to act out in their own self interest without limits in a world where we all have to live together and survive on the same scrap of dirt, nobody wins.
Part of the art of government is crafting a system which in which all controllers are themselves controlled. Hence the need for IP reform, as current IP laws grant control without any sane checks (allowing the MAFIAA to run rampant).
But maybe countertrolling already knows all this, and just wants to watch the world burn.
He's right. It is inaccurate, yet true. The spacecraft did use solar wind rather than thrusters to adjust it's trajectory for some maneuvers. It also used thrusters rather than solar wind to adjust trajectory for others. So the wording that would have made it both accurate and true would be "During its 6-year journey it used solar panels as sails, often relying on the solar wind instead of thrusters to adjust its trajectory"
It is possible that the submitter did understand the mechanics of the mission, and intended the 'often' to be implied. Then again, he may simply have been mistaken.
Well, I refuse to code without multiple screens. I just need too much open at once to work effectively with one screen.
And my coworker who uses linux uses compiz effects to switch between multiple virtual desktops in addition to the multiple monitors, so he's got the spinning 3D graphics down as well.
I still fear that Apple will start to boil the OS X frog. They have code signing and an app store in place. They have a warning dialog if you try to run software downloaded from anywhere else. They're clearly repositioning OS X server versus the regular version in Lion. My fear is that the regular version of Lion (or perhaps the version after it) will have lock-in, and you'll have to buy a $500 pro version with the server stuff in order to get an open Mac. If that happens, I'll shed a tear and jump ship to Linux.
To be fair, that warning dialog isn't unique to mac, and I don't really mind my computer informing me of where something came from the first time I run it. It's kind of like when the credit card company calls me to verify after I make a big ticket purchase. Usually there isn't a problem, but it's nice that someone or something is watching to make sure that somebody sneaky isn't trying to do something nasty to me.
And I understood the point was that the server stuff was all included in the one single solitary edition of Lion. And even Paul Thurrott thinks this is a good idea.
But if I make a button saying "I like Coke" or "I hate Coke" or "I didn't have a Coke today", or if I write a book with the title "My first Coke", then this should not be a trademark infringement.
As long as you make it clear that the 'Coke' you are referring to is the beverage made by the Coca Cola Company and not some other beverage that you are calling Coke, while simultaneously making it equally clear that the Coca Cola Company in no way endorses your mentioning of their product.

Well, actually geothermal is nuclear. The reason the core of the earth is still molten is because of the energy released by radioisotope decay in the rock.
Well, right now it is doing all the microgravity science that was previously done by the space shuttle. FYI, Columbia was in fact on a microgravity science mission when it had its disaster.
Well, perhaps you wouldn't have been a paying customer. Just because you have the means to pay doesn't mean you will. If everything you say in the second paragraph is true, perhaps you would have just foregone watching the movie and done one of the other things you mention instead.
That's the genius behind iTunes and Amazon. They make legit purchasing as convenient as piracy, and it should come as no surprise that they are wildly successful while CD and DVD sales are plummeting.
Stealing a car and downloading an MP3 are NOT the same thing.
I'll say it again.
Stealing a car and downloading an MP3 are NOT the same thing.
See, when I steal your car, suddenly I have a car and you don't. But if I download an MP3 from you, I have an MP3, yet magically you still do as well.
If I were able to create a magical replicator that made an exact duplicate copy of your car, and then I drove off in my duplicate copy, then you could start comparing it to MP3 downloading. The auto industry might start complaining that I am 'stealing' their cars by duplicating them, and saying that my duplicated car is lost revenue to them. But I wouldn't have bought a car from them in the first place, and only drive the duplicated car because I was able to duplicate it for free.
Do you understand the difference yet?

Actually, it is very useful to know what output your wind farm will have in the next hour or in the next day. Utilities are constantly monitoring their generation resources so they can plan ahead.
It would be beneficial to Xcel to know today that tomorrow windfarm A will not be producing as much electricity, so they can make a deal now to buy that electricity from someplace else at better prices than if they suddenly had to buy in that electricity tomorrow when they realized their windfarm wasn't producing. Or maybe, they know that it will be very windy next week, so they make a deal with another utility to sell that extra power that they know they are going to have. Electricity is bought and sold up to months in advance of when it is actually generated, so it is very important to know how much you will be able to generate in that time. It's all economics.
I suppose then by that interpretation of the IAU definition, Jupiter is a dwarf planet. IMHO, the whole dwarf planet classification is just silly, and completely meaningless.
