It doesn't matter what temperature you run your reactor at. They're not putting the water and CO2 into the nuclear core. They're just using the electrical power generated by the reactor.

Splitting a statement between the first line and the subject is bad form.

By posting "I'm fine", they clearly were not "people in a disaster". However, they could have been a block or two away from the disaster and thought it important to let people know their status.

Who says you can't make money from things in the public domain? Where do you think symphony orchestras get their material?

Italicised colon followed by a period to make the "therefore" symbol... clever.

I do miss the "swim across the Atlantic" bit they used to have.

But I miss far more, the old Google Calculator. You used to be able to stuff like "circumference of earth in football fields", but now-a-days it's not much better than a four function calculator.

Monsanto to the rescue, I'm sure.

Your perspective is warped. If characters performing behaviour that would get you thrown in jail were the criterion for making a movie bad, then we can toss Pulp Fiction; Kill Bill; Ocean's Eleven; Batman; The Usual Suspects; The Good, The Bad, and the Ugly; practically every western, actually; every crime movie; every vigilante movie; every horror movie; and a whole slew of others right on the trash heap.

So what you're saying is that your altitude is zero most of the time. Well, there's two options that fit.

Sorry, fourth or last option.

Chris Hadfield is retired from the Space Agency, and has been on Earth for almost two years now. He does lectures and book signings now. His home town of Sarnia is at 180 metres, so chalk up another vote for the third or last option.

It is a good picture, but I think I like this one better. It's got kind of a Michael Whelan feel to it.

Why not just build them in an inert state to begin with; like, say, Nebraska or Wyoming?

For the love of sanity why? The moon is 770 times as far away, which means you'd need a laser almost 600,000 times more powerful than one in Low Earth Orbit to deliver the same "punch". (Lasers spread out like any other beam of light, so inverse square law applies). Your aiming mechanism also needs to be magnitudes more accurate. If you're running this off solar power, then the moon based laser is going to be out of commission half the time, and is not going to be at peak energy most of the time. Furthermore, the launch costs are going to be astronomical.

A satellite based system can be in perpetual sunlight, with the solar panels constantly at the optimum angle for energy collection. You're right on top of the target, so aiming is easier and power delivered on target is greater.

Did you learn nothing from Fukushima? Don't build nuclear power plants in earthquake zones! Bad idea.
