They did, since the grid really became interconnected and deregulated.
Ontario's been selling off excess nuclear at below-zero for years. They can't throttle it, someone has to take it, so they pay New York and Michigan to throttle down their coal and gas plants.
This has been happening for decades, except now we conflate it with renewables because there's millions of dollars in ad buys being spent to tell you how bad all of this is.
> Why pay $700 for a phone if you just you it to send text messages and run few simple apps?
Well for one, you're not paying $700, you're paying the delta between $700 and whatever other phone you buy. In a better-case scenario where you get something like the Moto X, that's more like $300.
So why pay $300? Well if all the people at the other end of the connection are on iPhones, it gets you iMessage, FaceTime, AirDrop and many other features. I know I find those compelling. $300 compelling.
So exactly what everyone has been saying without variation since the Alsos teams arrived in Paris in 1944 turns out to be correct?
Slow news day.
p.s. Had a nice chat with one of the Alsos guys once. Described showing up in one of the labs and everyone there being shocked to see just who was walking through the door. All their former colleges were in fatigues, which they kinda thought was weird. But then when they explained why they were there, and what they were trying to stop, all of the Germans immediately went "What?!? No, we were never doing that!" but then understood why they were in uniform and armed.
No, it's not different at all. Anyone can go to the local reference library and get any of these references. If you're complaint is that you can't do it for free from your compute, well join the 70% of the population of world that can't do that *ever*.
Which is precisely why SETI works in radio frequencies.
If we turned our best telescopes on Earth, we would only detect ourselves out to about 10 ly (although I bet that's improved). The only hope we have of finding an ET thus requires them to be deliberately signalling back to civilizations like ours. We assume they would do that in the radio frequencies simply because that's what we'd do.
Sure, these other systems might be useful, but we can't spy on them. So in the meantime...
> Not quite, he's saying there's lots left to discover. There just might not be anything left for the LHC to discover.
Not quite, he's saying there's lots left to discover. We just don't know how to build the machine to discover it.
But of course that's really just particle scientists talking to accelerator builders. Astronomers are discovering new physics all the time, and its so weird that most in the field cover their ears, chant "la la la!" and pretend it doesn't exist.
Like, for instance, the story that came up right here on/. a few days ago about a fully developed galaxy only a few million years after the start of time. Nothing we currently know can explain this, so we just say it started that way. No problem! Black hole information paradox? Who cares! Mach's principle is based on what, exactly? The "distant stars"! Wavefunction collapse? Shut up and do your homework!
> Not too long ago, a Forbes writer declared that a liberal arts degree had "become tech's hottest ticket."
I've been hearing this refrain every couple of years since I was in university. That was so long ago our connection to the world was BITNET.
Having worked in or for several dozen companies over that span, I've seen no indication that liberal arts are hired more or less than anyone else. I call BS.
It's a totally reasonable deal - it's at least as good as the ones you get from the phone companies, and much *much* better than what you get from your credit card company.
Let's see, Apple does *exactly* what everyone else is already doing, for a slightly lower cost, with clearly defined terms and nothing hidden in the price, and slightly improved conditions (AC+).
"how do I determine the Ah equivalent, which is what batteries are actually sized in"
That's how lead-acid and other older technologies are actually sized in. Several reasons why. One is they have a slow decline in voltage during discharge, so over the entire cycle the voltage may vary perhaps 35%. Combined with that is the voltage sag. So for these batteries you have a wide span of curves.
In contrast, lipos are *much* flatter. They hold their voltage until they're 90% discharged (or more) and then suddenly fall flat. They also don't have the same sort of sag curves. So you can generally get away with assuming the kWh and Ah are linear, and kWh is far easier to use in practice.
> But they have a tendency to cause expensive machinery to go up in smoke
That's li*co* batteries, not the li*po* batteries we're talking about here. Lipo batteries are just as safe as lead acid, at the cost of decreased energy density compared to lico.
"People with off-grid systems are getting much better results than that."
No they aren't. I sold them for a living. We wouldn't do anything beyond 50% DoD, and customers that did burned out their batteries.
At any size around 5000Wh or larger the lipos started pulling ahead in lifetime cost. Once you factor in maintenance-free operation and the fact that they're half the size and weight, there's no contest. And that's when they cost 80/Wh.

Actually electric cars will add very little to the grid load.

I did a similar calculation for the UK, where it appears the slack in existing generation assets will cover all the driven miles.

When they stop being the largest and most profitable company in all of recorded history, with the number 1, 2 and 7 best selling phones on the planet?
Duh.
I hear iRan is pretty much up for sale.

We do this all the time, they're called "books".

_EVERY_ time somebody says "There's nothing new to be learned",
That's great, but that's not what the article says.
It says we don't know how to build the machine that will demonstrate the new stuff.
This is why paywalls suck:

They just keep hitting it out of the park!
> So about $70 more over the course of a year.
Which is significantly less than the AC+.
> however if you read the fine print, you are allowed 2 accidental damage incidents a year
So, two more than the ATT next plan then?
> but with an additional fee of $100 per incident
$70 + $100 $700 for a new phone.
If you think ATT is offering you a better deal, by all means, go for it. Don't cry if you drop your phone though.
It's a totally reasonable deal - it's at least as good as the ones you get from the phone companies, and much *much* better than what you get from your credit card company.
> they don't have to realize they are paying $200 in interest
Opportunity cost on that is what, $150? Seems like a perfectly reasonable decision to me, at least financially.
My problem is the vendor lock-in, which is amusing considering its an unlocked phone. That part I need to read more carefully.
Let's see, Apple does *exactly* what everyone else is already doing, for a slightly lower cost, with clearly defined terms and nothing hidden in the price, and slightly improved conditions (AC+).
Apple is evil. ::rolleyes::
Double that for Canada.
Let the race to the bottom begin! Lets see Samsung make a dime now.
Apple execs must be laughing their heads off.
