No motive mentioned. The guy was probably annoyed by the stupid helicopter hovering over a residential area at night. Stop doing that and the problem is solved. Bad city planning is often a cause of crime, which is why there is so much of it in America. And why does a ship need a helicopter escort? If it's so important, they should make the ship wait until morning. That will never happen of course, because it would cost the shipper money. Screw the people living in town. If you ask me, the helicopter pilot was the one who should be in jail.

In fact the best way to look for aliens capable of mega-engineering (like Dyson spheres) would be too look for telltale flares of vast quantities of infrared radiation. But there aren't any around.

Also why show pictures of a wind hose or a crystal?

If it were likely that "accidental" cell phone use would crash airplanes it already would have happened. It doesn't even have to be very likely for a ban on bringing cell phones on planes. They even ban carry on shampoo. The whole thing is a farce.

This isn't really true. Nice story though. Georges Lemaître proposed a similar idea but didn't provide enough scientific detail to really discuss.

Didn't find any reference to Saudi Arabia in your link.

Comments about how "stupid" the operators of Fukushima or Chernobyl were remind me of that story in "The Right Stuff" about how the the pilots always reassure their wives that flying isn't dangerous if you are a good pilot. Every time a good pilot gets killed they deal with the cognitive dissonance by saying it was pilot error and pinning it on his personality in some complicated, technically detailed narrative.

Nonsense. High food prices help the very poor because the poorest people in the world are primary producers.

Actually the problem is you can't insure a nuke. The Fukushima cleanup is going to cost $300bn or so. No company in the world can have that kind of risk on its balance sheet.

Actually China has been contributing more to CO2 reduction than any other country.

You'd need a dedicated road for this. Might as well build a train.

It is traded in dollars because the dollar is the reserve currency, not because most of the world's wealth is in the US. It isn't. The US economy is smaller than the EU economy.

They used to tell this story about the Soviet Union.

If his name is Raj the Germans will pronounce it Ray.
