What is with this policy? We've killed it - repeatedly and it just won't stay dead.

I mean we know they're doing intercepts of some sort anyway, and we know they retain probably quite a bit, but the big benefit at the moment is none of this can be used in court.

And for the types of things it's worth stopping, you don't need to use it since if you grab some terrorists with a couple kilograms of fertilizer and diesel in a truck, then you've got all your evidence.

What seems way more likely to me is that this is being pushed hard by the copyright lobby, who, once they can legally obtain the data, will want to use it to go after people.

What's the economic damage of shutdowns due to tornados?

A lot of talk about a city's traffic problems essentially focuses on the fact that a major car accident can wipe out productivity for an entire morning or day in a metropolis. How much productivity is being lost due to tornados? If you could prevent them entirely, then it could easily pay back many, many times the construction cost.

The Slashdot armchair physicist brigade is out in force I see...

...kaiju protection.

Mythbusters debunks this. Every single pressure vessel explosion they've ever done has involved having to disable 2-3 different safety features in dramatic ways, and then subjecting the whole thing to absurdly extreme conditions before anything happens.

Which would be relevant if SUV's were remotely safe...

As it stood for a long time, SUVs were big...and little else. Any car with a decent roll cage and side-airbags was likely going to come out of all but the most disasterous scrapes much better, since it wouldn't be rolling and caving in the roof on it's occupants.

Diesels cannot, in anyway, be scalably filled with carbon neutral fuel. Biodiesel and it's ilk have all the same problems as ethanol.

CO2 sequestration as conventionally imagined is just a huge hand out to the coal industry though. Depending on geological strata which no one's even sure can reliably hold that much CO2 as an energy plan is just absurd. It's a plan we don't know will work, which has a limited range of viability to start with, and the results to date are not promising.

That said, Orico and the CSIRO in Australia have been doing something much cooler with the idea: chemical reactors where heat and CO2 is reacted with minerals to permanently sequester it as carbonate rock which can be dumped (or as they propose: refined into concrete). That process I fully support, since they're proposing running it as a retrofit to pretty much any fossil fuel powerplant, anywhere.

The point is that hydrogen is very light. It doesn't easily accumulate in rooms since it's much lighter then air - when it leaks it disperses. Unlike say, heavy petroleum fumes, which hang around and accumulate near the ground.

The number of responses restating that "no they're evil, you're stupid if you can't see it" is exactly my point.

Given that the cartels build submarines for this, the thing I'm surprised is that there's never been "drug smuggling by ballistic rocket".

You do realize that the newer systems simply autoland when they lose control, and that new thing with GPS will simply move to dead hover until the RF interference passes.

Meanwhile, as you obliterate parts of the cellband nearby, the FCC is going to be pretty highly motivated to find you.

Please outline the evil Google has done.

You know, actual events, not your imagined slights because somewhere, somehow, they might someday do something.

Who in their right mind would have used Dropcam in their home to start with?

The news here certainly isn't Google buying it...

It will be if it can't sell products to the US government.
