Don't forget the multi-megawatt radiators needed to provide a cold sink for those reactors. Chemical rocket engines dump heat into the exhaust gases but in a vacuum radiators have to be huge and heavy to get rid of significant amounts of heat from something like a nuclear reactor. They also have to be shaded from sunlight to stop them absorbing heat...

There is always Nuclear Thermal Rockets which pour the reactors heat into the propellant.

They're getting cracked because they're not paying attention to their security.

But start-ups are all about the most buzz you can generate in the shortest time. You need to get that product out the door ASAP because your competitors aren't going to wait for you to build your secure system first. After all, you're not in the business of security, you're in the business of connecting up the most people and building your community. /sacasm*

If a two-person rule is put into place, also put into place two switches further apart than arm's reach that have to be pressed in-sync or in very close succession.

So the pilot and co-pilot are in the cockpit and the door is locked. Then one of them has a heart attack and is incapacitated. Now no-one can get into the cockpit.

Regardless, was 16 schoolkids (amongst others) on that flight. You wanna hari kari? Go ahead, but keep it on your own dime.

Invoking "Think of the children" is just as bad here as anywhere else. None of the people on that plane deserved what happened to them*

Could someone fill me in on the economics of nuclear power generation? I'd like to know what the usual payback period for a plant is, and how much it costs to operate a plant over that period.

Well in terms of foreign aid and keeping a positive political presence in the area, the payback for Russia is priceless.

Yep, yep, sorry... Apple (as an organization) has consistently delivered hardware that we could count on, met or surpassed our needs (and alternative vendors)

Devils Advocate here, look what Apple did by gutting the hardware specs of the latest release of the Mac Mini. In addition they had slowly been morphing their hardware into something that is pure commodity - no user changeable RAM, Flash etc so you have to pay the full Apple price for those items when you buy the complete system, and you are limited by what they offer on the Apple store. As a result their hardware offerings are becoming less desirable every year to the point that I am considering that my next apple computer will be a hackintosh.

And I say that with 2 Apple computers, an iPad, an iPod touch and an iPod nano on my desk (and a Mac Mini in the other room)

In the U.S. the supreme court allows mandatory checkpoints only because they are pre-published where the driver has the ability to be informed and can take a different route.

There is also the fact that the US government defines the "border" as including 100 mile in from the physical border and can pretty well do what it likes in that zone. This "border" conveniently includes where the majority of the population lives. Are You Living in the Government's "Border" Zone?
