Comment Re:Seemed like a good idea at the time (Score 1) 222

For cars the environmental effects were also an order of magnitude lower than the alternative: horses.
Cities had trouble getting rid of all the dung from the horses by the time cars came around. Cars didn't smell as much and the exhaust simply flew away instead of staying in the middle of the road.

'Round here we have a 2 tier system for a lot of houses. Day power and night power. Night power is cheaper because then the high power users (industry mostly) are down. People who have it wash at night because that is cheaper.
Once the amount of solar energy on the net becomes a problem the power companies will change this, the night becomes more expensive. Then many people with 2 tier systems will change their habits to wash during the day because that is cheaper.

Ergo here in the Netherlands the problem will be delayed automatically. Maybe enough to have grid scale storage.

This is for those that don't need the computing power. This is something in between a normal PC and a ChromeCast. Not as locked down but just as slow.
Now ChromeCast has a specific market: easy video streaming with your Android device as a remote. Whether this offers enough over that to find a real place in the market remains to be seen.
It does offer full windows or linux. That means the possibilities are far greater. Whether the processor is sufficient for enough of those possibilities will probably be a deciding factor in the market size for this.

For computer power this changes nothing in the possibilities of a real PC. They will probably be irreplaceable in that regard for a long time. These thumb size devices have far to little cooling power.
But such strength isn't always needed. Often a low power processor is sufficient: cat videos don't need much power.

if their devices had the "unknown sources" setting enabled.

That is an advanced user setting. It should not be changed unless the user is certain. It even triggers a warning if you change it.
Only change that if you are certain you can use the device safely without it.
If you can't, then leave it in it's factory setting.

Stupid is as stupid does.

Comment Re:Rooftop seems unlikely (Score 1) 516

They come with free overheating problems. Solar panels need the airflow behind them to keep cool. Cool is efficient, hot is inefficient.
Insulating your house is good, insulating the back of your solar panels isn't.

Untill a company builds a layered system that has tile like solar panels on top, some air flowing freely below it and then insulation I would just stick solar panels on a roof unless the looks are really important (in sight from the street in an old city for example)

The sensitivity in measuring one effect is no guarantee it will measure any other effect.
As far as I know neither of the Voyagers is fitted with an atomic clock so this measurement method does not work on it.

According to the article dark energy signatures would be evident in slight time shifts. Slight as in in the range of "billionth of a second". Light travels 30 cm (1 foot) in that time.
According to the article GPS satellites can measure those. They just don't check if there is a pattern to them. That pattern would indicate the presence of dark matter.

GPS satellites have Cesium clocks. Those are accurate to one second in 1,400,000 years. That means the error the article is talking about is the error the clock naturally has over about half a day. Apparently that is precise enough.

Comment Re:How about "not diamond"? (Score 5, Insightful) 79

According to the preview on the Nature site each carbon atom is linked to 3 other carbon atoms and one hydrogen. Plastic is a better description than diamond. "Normal" carbon nanotubes are closer to diamond than this.
The preview didn't call it a diamond by the way. It does equate it's properties to diamondoids and nanotubes.

Having said that, if the result is a non-toxic high tensile strength material that can be used to make a space elevator then I don't really care what they call it. It's cool anyway.
They could call it "Superdung" and I'd still love the stuff.
