If a foreign government agency had spent years gathering data, and was mining it for undisclosed (possibly nefarious) purposes, It would be known as a dangerous spy network, would be subjected to infiltration/corruption and possible attack. I completely fail to understand why people tell FB anything about themselves ever, and don't request immediate deletion of all the data held about them. When governments try and spy on someone, they get all upset about it, when FB does it, and freely allows the data to be sold to the highest bidder/anyone who cares to look, people think its really cool and useful. what does it take for people to say enough is enough? Is it too late now, since the data is already gathered? why do I fail to see the upside of FB and its data gathering ilk?

Would using graphene as a kind of laser printer toner, allow us to print out circuit boards on paper? or does it need to be in a structure, that would prevent the electrical properties of the fused dust being useful?

Dear America, Please don't mine the entire ocean with giant non-robotic sea mines, just because you can, signed, the rest of the world. Also, didn't we have this conversation last week?

well they sound like mines,could look like mines, could act like mines, are being researched by the US military, will be under the control of the US military, and can have ANY payloads attached the US military see fit. In fact its such a great idea , I can believe no one thought of it before ........... oh wait....

Indeed, covering Giant robotic Sea Mines, with so much legal astroturf that they sound like a good idea to the American government, does not unfortunately remove the fact that they are giant robotic sea mines. If the US needs any help , from whats left of the British navy, I'm sure a treaty can be fabricated to get us to lay a few for you too....

Since it is the standard, surely its the world that needs to bend a little (space-time wise) to fit in with the new standard? surely the standard (master) kilo still weighs exactly 1 kg by definition?

count me as one of them lost tourists/fliers. I have spent lots of time in the USA, and have flown there from the UK on many occasions, before and after the 9/11 attacks. unfortunately, due to some rough treatment by customs/border guards on my last trip, I have flat out refused to ever go there again......

I'm on Virgin media in London, UK and I can see the promo site just fine
