Submission + - Are roads safer with no central white lines?

Press2ToContinue writes: White lines along the center of roads have been removed in parts of the UK, with some experts saying it encourages motorists to slow down. So is it the beginning of the end for the central road marking?

You are driving along the road when the dotted white line that has been your companion — separating your car from oncoming traffic — suddenly disappears.

One theory is that you will slow down, making the road safer.

What could possibly go wrong?

Submission + - Skylake Breaks 7GHz In Intel Overclocking World Record (hothardware.com)

MojoKid writes: Intel's latest generation of processors built on the Skylake architecture are efficient as well as seriously fast. The flagship, Core i7-6700K, is an interesting chip as it's clocked at a base 4GHz, and can peak at 4.2GHz with Turbo Boost. Of course, as fast as the 6700K is, overclocking can always help take things to the next level, or at least temporarily explore future potential. In Chi-Kui Lam's case, he did just that, and managed to break a world record for Intel processors along the way. Equipped with an ASRock motherboard, G.SKILL memory, and a beefy 1.3KW Antec power supply — not to mention liquid nitrogen — Lam managed to break through the 7GHz barrier to settle in at 7025.66MHz. A CPU-Z screenshot shows us that all cores but one were disabled — something traditionally done to improve the chances of reaching such high clock speeds.

1. The amount (by volume) of carbon dioxide in the atmosphere is so small,

So this process might work best if installed at a major CO2 point source. Like a power plant.

2. It takes at least as much energy to reverse combustion as you get when you burn something.

This is true. So if you produced that additional heat energy needed to convert that CO2 (ideally from a non CO2 producing heat source) then why not just replace the CO2 emitting process with that heat source in the first place.

I think the people that came up with this idea would be the ones who would build the Eiffel Tower to put a flashing red light on top of it so planes won't hit it.

Trust me, it makes no sense... I can guarantee you that it takes a lot more energy input than you can get out of the methanol.

And which is then going to just ... release all of that carbon dioxide.

It isn't magic.

But, in case you really needed to know:

but they admit that such a system may be five to 10 years away and will probably be still more expensive than ordinary fuel production.

Which over the years I have taken to mean "it kind works in the lab, we need to publish now, but there will never be any applications of this technology on a meaningful scale".

An awful lot of things which are 5-10 years away are really never going to happen. In fact, most such things are pretty much doomed to never be useful.

Not saying basic research isn't cool, but I don't think we'll expect to see this any time soon.

Now, if you can make ethanol, we're listening. Why no, officer, that's not a still ... ;-)

Bush and Christie hitting one-time Senator Rubio out on lack of experience

It is funny how they keep trying to compare him to President Lawnchair without directly comparing him to President Lawnchair. That is of course their aim with the "first term senator" comparison, but they don't want to accidentally mention that they are taking most of the "new" campaign ideas from the Obama campaign. They also don't want to mention that the same health care bill that has his name on it - that they demanded as the only thing they would vote for - is the bill that they want to repeal and then replace with itself (with someone else's name on it, of course!).

It does make for good entertainment, watching the GOP self-destruct in this cycle. Maybe if we're lucky the damage with be lasting and we can get some work done in DC.

Comment that would be nice, but weather systems are big (Score 2, Insightful) 100

First I want to be clear - wind is a great supplemental power source in some areas. Having said that ...

> they are spread around national grids so the wind is always blowing on some somewhere.

It would be nice if any of those three things were true. In fact, weather systems are generally larger than most countries. Here's the current weather map for a very large country, the United States:
http://sirocco.accuweather.com...

You'll notice there's very little weather in the US today. Next week, a storm system may cover most of the population of the US.

Regarding "national electric grid" - you may recall a few years ago a blackout left the northeast without power for several days, while the nine other power regional grids including had plenty of power. The California grid had a chronic power shortage for decades, while the neighboring grid for Texas was fine. There are 10 regional power grids in the US. There's no such thing as "the national grid", and can't without save a complete redesign of the technology and replacing billions in infrastructure.

Lastly, wind farms are NOT spread evenly around the country. They are located in specific areas where it makes sense to have them. You need steady, predictable wind (the cube power law means high winds destroy them), near population centers, but with cheap real estate. The last two requirements are of course contradictory, so a limited number of locations fit all of the criteria.

In those places where it DOES make sense, wind power allows producers to reduce fuel usage on the natural gas generators whenever the wind happens to be right, and that's a good thing.

Comment Re:can't the state do something about this? (Score 1) 155

States (utility commissions) generally regulate the relationship between the company and the customers (state residents). Things like utility rates, terms of service, etc. Everything on the back end (subcontractors, labor negotiations, etc.) works pretty much the same as any other private company doing business in that state or across state lines.

Comment if "flexible" means uncontrollable 100X variation (Score 1) 100

> The next thing you need to know is that renewable, whilst mostly very flexible

"Flexible" is an interesting word choice. Consider wind, for example. A 20 mph wind has 8 times as much power as a 10 mph wind, at 30 mph it's 27 times as much power. You can't control how much wind there is. Similarly, we might not realize it since our eyes measure brightness on logarithmic scale, but a cloudy day has 95% less solar energy than a sunny day. Most people would probably call this "unpredictable" or "unreliable" rather than "flexible".

On the other hand, the operators of a typical small natural gas plant with 4 generators can choose to run anywhere from full throttle on all four to just one at half throttle.
