Gas is no good, it emits roughly 50% of the amount of CO2 that coal does, it's a big emitter. We need to cut CO2 emissions nearly 100%, we're not going to do that with burning gas.
And for every Megawatt of Hydro-electric capacity you have you can match it with a megawatt of wind/solar and it doesn't matter how intermittent the wind / solar is because you have the hydro as back-up.
Solar panels do not need rare earths, they can be made without them, same goes for wind turbines. "the energy cost of creating solar panels isn't" [falling]: Flat out wrong, see: Whatâ(TM)s the EROI of Solar? | Ramez Naam
The term "rare earth" is an archaic one, dating back to the elementsâ(TM) discovery by a Swedish army lieutenant in 1787. In fact, most (though not all) of the 15 (or 16, or 17, depending on which scientist youâ(TM)re talking to) elements are fairly common; several of them are more abundant in the Earthâ(TM)s crust than lead or nitrogen.
Rare earths are sourced from China because they sell them cheap. Declining solar panel performance is not an issue, good solar panels decline at less than 0.5% performance per year, that means they will still be going with 50% of their original efficiency 100 years from now. Energy density is not a problem. See: Land Art Generator Initiative A huge transition to solar panels will occur for one simple reason: price, solar+battery storage is expected to continue falling to as low as 2c per kWh of solar+battery.
As someone who's worked in construction, I wouldn't go near this place as a construction worker. Construction firms have a very bad habit of not providing suitable masks, they tend to provide 'comfort' masks which have no protective value.
So, we've had an industrial revolution, a technical revolution and lately the IT revolution, these should of resulted in less work, so why are people working long hours?
You could point out that people used to work 60-70 hours per week, but I'd point out in return that those people likely lived a few minutes away from where they worked and so the situation is nearly as bad now as it was a hundred years ago if you take commuting in to account. Salaried workers are working 49 hours per week and often commuting 10+ hours per week.
If the French can live comfortably with a 35 hour working week then why can't the rest of us?
Rubbish, you have very few rights for the first couple of years, if you want to make someone redundant then you're free to do so, if you want to fire someone who's not pulling there weight then you tell them twice to pull their socks up then you fire them but larger companies mostly don't give a stuff about people who don't pull their weight.
Or are you wishing to fire someone who's worked for the firm 2+ years because you don't like them?
Complete rubbish, modern turbines are expected to last 40 years, even offshore turbines can produce electricity cheaper than nuclear. Denmark for instance gets a high percentage of it's electricity from wind and it's paying under 10c per kwh and that's including subsidies, when the subsidies end it'll be less than 10c per kwh. (10c euro)
I think it's mostly a matter of laziness, people are too lazy to think for themselves or to think at all, this is why Trump is doing so well, he appeals to people who don't think, they are an embarrassment to the species.
Lift makers can't even get a simple thing like a lift right.
I've seen/heard animated up arrows when going down, declaring door closing when it's not, declaring lift going up/down when it's not going anywhere, and to top if off, lift declaring completely wrong floor numbers.
If we can't get simple shit like lifts right, what hope is there for getting robots right?
You should get an account to post, it'll be seen by more people.
What you said is a bit technical for me, it sounds expensive, what the world needs is cheap easy to fit solar. If it can get a high proportion of diffused light then that's good but it still needs to be cheap / manufacturable.
Actually it's still a challenge, I had to type in Russian letters, zoom in on a tv screen, hunt for road signs, still make guesses based on countryside, road markings etc. My places were more diverse, I got Argentina middle of nowhere, ditto for Iceland, Russia and Canada.
That's the way I like it because it means my OS is mine and not just a locked down part of a larger system which tells every advertiser who I am and it allows me to read and write anonymously like people have been able to since the beginning of print. These big digital trust systems, I don't trust them because the people running corporations and governments are highly untrustworthy.
Because they may have written their own abstraction layers to encapsulate multiple platforms
Doesn't seem to be done that way, I say this because it's often a third party that handles the 'port' to PC, if they were using what you describe then they wouldn't need to use a third party to port a game.
Researchers from the University of Surrey in the U.K. studied the eyes of moths to create sheets of graphene that they claim is the most light-absorbent material ever created.
I doubt this very much, the best solar collectors will collect 46% of light, but of course they don't come cheap, current cheap cells are the ones collecting up to 15 to 22% of light.
Cell Efficiency Chart (jpg)If the researchers had created solar collectors with more than 46% efficiency then they would say what the efficiency is and have it verified and it would be big news.
I just hunted around for street signs and googled them! Cheating no doubt but fiendishly difficult otherwise when you've got nothing to go on other than a road and some fir trees.
Eh? Trump doesn't even know what his agenda is, he just spouts the first crap that comes out of his mouth without thinking, he's utterly ignorant and doesn't have much in the way of policies, some of what he's come out with is completely absurd and unworkable. Trump would f**k America up if he got his way.
Both are willing to take up the fights they believe in,
You're trippin, Trump only believes in becoming more rich and powerful, he doesn't give a rats arse about most of what he talks about.
That's pretty dreadful, I'm glad we have the option of a third party to oversee justice here. Without the option of court, the govt has no incentive to be just during appeals.
Can they even do that? I don't see why apple would be making a fuss if it were just about the terrorists phone. Aren't the FBI asking for all iPhones to be back-doored so that they can get easy access in the future.
She stood by Appleâ(TM)s decision to fight a federal court order to create software that would allow federal authorities to access the shooterâ(TM)s password-blocked iPhone. The software would allow authorities to retrieve personal banking passwords, photos and other information.
Sounds like a judge who doesn't understand the tech just asked Apple to ruin the lock to the phone, it wouldn't just be the government who could unlock any phone, hackers would likely learn also how to unlock any phone.

That's complete bollocks quite frankly.

Wind costs so high? maybe a decade ago, not now.

And there is plenty of competition in the wind turbine market.

Lets leave the bible out of this please.
Unless you're Donald Trump and then apparently it's OK.
This isn't the first time us Brits have come up with solar for cloudy days. See:
British scientists develop solar panels which work better on a cloudy day [March 2014]
Both articles lack details about the efficiency in diffused light conditions.

The patent licenses will likely cost more than the drive hardware itself. I'm not kidding.

Also wrong,
It's not a stand-alone theory anyway, it requires quantum theory...
Article can say it better:
Why can't Einstein and Quantum Mechanics get along?
Can they even do that? I don't see why apple would be making a fuss if it were just about the terrorists phone. Aren't the FBI asking for all iPhones to be back-doored so that they can get easy access in the future.
