I didn't research so forgive my ignorance

It gets this property from its fine surface structure, which is a forest of tubes. Incoming light has to be reflected many times before it gets back out, so a black material is effectively made even less reflective. It's the optical-scale version of the pointed absorbers used in anechoic chambers.

It probably is not going to retain its blackness when exposed to water, dirt, or wear. Superhydrophobic coatings such as Never Wet have the same problem - they work because they're composed of tiny points, so droplets of liquid don't have a surface they can grab. But after some wear, the effect stops working. (See any of the many "NeverWet fails" videos on YouTube.)

This is likely to be great for protected environments, such as inside optical systems. It should be useful for optical sensors in space, too. But it's probably an inherently fragile surface. That limits its uses. (The "stronger than steel" probably refers to the individual carbon nanotubes, not the bulk material.)

This s a problem with a lot of surface chemistry stuff touted as "nanomaterials". They have interesting surface properties, but the surfaces are fragile, because they're some very thin surface layer with an unusual structure. If you protect that structure with some coating, you lose the effect.

It's also a market distortion if one locale doesn't regulate pollution and allows businesses to dump waste in communal resources (e.g. rivers), making them externalities. A tariff on imports of such goods can be a way of redressing that balance - manufacturers have to pay the costs irrespective of where they produce the goods if they want to sell them in a particular country.

Many French People in rural France loathe the Parisiennes. When a car with a Paris Department number plate comes to my Village the locals suddenly become sullen and un-coopoerative towards the visitors. When the car leaves, life returns to normal. Even to a 'Les Rostbiff' like me they are far friendlier that they are to anyone from Paris.

The same is true in reverse too. I picked up quite a thick rural Normandy accent[1] when I speak French and discovered that everyone in Paris is a lot more polite to me if I speak French with an English accent...

[1] Cultural equivalents: For brits, think Devonshire farmer, for americans think deep south.

Comment Re:2-year CFLs (Score 1) 278

I took some with me when I moved about 10 years ago. I didn't the last couple of times I moved, because they're so cheap that it's not worth the effort to move them. I have had one fail in under 4 years, but most of the ones I installed when I moved into my last-but-one house were still working fine when I moved out 7 years later.

Maybe not. The law says they need to charge shipping costs, so unless their couriers are charging them â0.01 they are probably not complying. They are just hoping that it takes the authorities a long time to get around to forcing them to charge the real price, which will be obfuscated as much as possible, by which time the will have forced even more of the competition out of business.

They looked over the channel and saw what has happened in the UK. Most places are what we call "clone towns", which all have exactly the same set of chain shops. There are very few independents left in most places. Choice is non-existent, as even where there are multiple chains they both tend to carry the same products and only differentiate (slightly) on price.

Displays

Nano-Pixels Hold Potential For Screens Far Denser Than Today's Best 129

Zothecula (1870348) writes "The Retina displays featured on Apple's iPhone 4 and 5 models pack a pixel density of 326 ppi, with individual pixels measuring 78 micrometers. That might seem plenty good enough given the average human eye is unable to differentiate between the individual pixels, but scientists in the UK have now developed technology that could lead to extremely high-resolution displays that put such pixel densities to shame."

Google Now, or something like it. Forget about messing around with shortcut buttons and apps, I just want something that tells me what I need to know when I look at it. For example, as I get up to leave work I want to vibrate and notify me of traffic on my usual route. When I get to the airport I want my flight info displayed with the gate number.

Throw in some basic health monitoring (steps, maybe heart rate), a round face (square just looks stupid for some reason) and wireless charging. Most importantly it needs to be comfortable, and I'd expect it to be durable and waterproof so I can wash it off every now and then. Anti-bacterial coating would be nice too.

The Moto 360 is looking good on this front, except perhaps for the strap. It remains to be seen how well it works though.
