The way this works is that Google buys 120% of the power it needs from these renewable producers. It pays the grid operator to deliver 120% of its power requirement to its various data centers. It pays the grid to deliver the whole 120%. If Google only uses 100% of the power it is paying to have delivered, there is an additional 20% of power being fed into the grid. More likely, the renewable plants are delivering 200% or more of Google's instantaneous usage during the sunlight hours and that excess power get delivered to other consumers.
The grid doesn't care where power comes from after it is on the grid. It only knows how much power that is being put on the grid cost. If it gets a free 20% of Googles' power plus the transport fee from Google for that extra 20%,that is pure profit. At any given instance the grid looks at all power sources to determine where it can get the cheapest power to meet its anticipated demand. During the time the renewable plants are producing, the grid uses that power and tell the other sources to pound sand. The grid doesn't care if power is renewable or not. It only cares how much money it can make at any given instance. If it has more power sources than it needs, it can refuse power from peaker plants and they will reduce the amount of power that they produce. These plants are usually gas fired steam plants that can easily be dialed back, These peaker plants will probably become battery storage plants in the future when there are more renewable sources available than the total required peak load. In the end, the total amount of renewable energy gets consumed by somebody.
The grid operator loves it since they are essentially "buying" electricity for a negative price. When the sun goes down or the wind stops, the renewable plant stops putting energy on the grid and the grid has to start paying the carbon based peaker plants to make energy again. Maybe, at some point in the future, it will be able to draw down the battery storage before using the peaker plants. This works out great for the grid operators since their is much higher demand during the day than at night. The two big losers here are the non-renewable fuel suppliers since they aren't running the peaker plants as much and Google since they are overpaying for a specific amount of renewable power source to be generated and transported. The renewable producers are not likely to have many companies like Google to buy their power at a premium. Most companies will buy what is cheapest so the renewable operators will have to compete on price with the fossil producers.
While Teddy Roosevelt may have indeed expanded government, it was back in 1901-1909. I believe the Roosevelt you were referring to was good ole Franklin D.
Man I hate to jump in on this since I know I'll get flamed to a cinder but...
I hate to just post questions, but if anyone knows, I think we all deserve to know what everyone is trying to hide from us!! This bugs the hell out of me, and I hope I am not the only one:(
1. What is the standard, uncompromised compression rate for full HD video? eg. The rate of compression on a Blue Ray disc.
Most MPEG video is encoded at a variable bit rate. The ATSC standard for broadcast HD is something around 19.2 Mb/s but, as most have pointed out, a lot of stations statistically multiplex multiple programs into that 19.2. I believe that most source MPEG is kept at about 54 Mb/s before it is further compressed and distributed to the broadcasters.
2. What is the standard compression rate for cable HD video? eg. What I can expect from Time Warner.
It depends. If they are using MPEG2 which most still do, they probably only get 4 programs into a single channel. As newer settops that support MPEG4 get into their systems, they will do the same thing that DIRECTV does and go to 8 or 10 programs per channel.
3. What does Apple and Netflix (if they have a service) think they can get away with? eg. What they'll stream to me when I buy/rent something from their movie service.
My guess is that they will have to provide at least 6 Mb/s to get reasonable quality MPEG4 content
And finally,
4. What is the bit rate or internet throughput required to stream true uncompromised HD video? I ask this, because I am in doubt as to whether most cable and DSL connections are even fast enough.
True uncompromised HD video is just digitized but not compressed. In a really fast moving scene with lots of changing picture elements, this could be up to 30 full frames of JPEG images per second. turns out that's a lot of bits.
My TV isn't HD, and even with regular resolution programming, the quality is hideous. All jpeg-ed out, I like to call it. If they can't deliver regular programming properly, it makes me wonder how we are to expect them to deliver quality HD. And since I already know they can't, it is disturbing how they can claim they can, and are. Because I thought there already was a name for sub-HD video: Enhanced Definition, or ED, or rather, High Definition Erectile Disfunction TV!
You paid for the 8-tracks which includes a fair use license for the music. Just rip the music off to Audio Compact Discs or MP3s and destroy the 8-tracks. If you have any questions, just contact the RIAA which will assist you in preserving your rights.
Didn't anybody ever watch TROMA's "The Toxic Advenger". What's going to happen to these bugs after they've eaten all the plutonium and come after the people? Oh, the humanity!
I did the same thing almost the same time ago. I had 5 computers in my home running Symantic AV. The subscriptions kept expiring on a seemingly continuous rotation. Looking at the logs, none of them had detected a single virus in over a year. I finally decided to develop a system of backing up any critical files on a regular basis and a proceedure for reloading my systems if they were affected by any malware that came along. I removed all protection from my systems and waited for the worst.
It's a year later and, other than my systems running almost twice as fast and having a lot fewer weird hangups and crashes, I have not had a single problem.
I call BS on this one. I have been to Japan and they have the most backward banking system in the world. I only know of three ATM's in Tokyo that will even accept a foreign bank card. I'm sure that there are probably more, but that's just around the Shinjuku area. Given the lack of ATM's, I have found myself forced to get a cash advance from a VISA card at a bank. This operation is the most time consuming thing I have ever tried. It's like you have to schedule an appointment and then talk to three different people. Then you go sit down in a lobby and maybe an hour later they come get you and give you the money.
Actually, I believe that most DVD's today use VBR (Variable Bit Rate) "Program Streams" (not to be confused with MPEG-2 Transport Streams used by broadcasters) and therefore do not pad out the content. This is the same technique used for ATSC broadcast. The 19.2 Mbps equals roughly the 8.5 GBph or 20 GB for a movie with extras and multiple audio tracks.
I saw an article that SONY had decided to stick with MPEG2 initially for HD DVD releases (of course they will use Blu-Ray format). Their thinking was that there is enough room on the disk, and MPEG-2 compression technology is mature compared to H.264 (MPEG-4). The HD DVD players (be they Blu-Ray or HD-DVD or both) will include MPEG-2 and MPEG-4 decoders as well as WM9 so they can change at a later date when the technology catches up.
Actually this is not true. The article says Comcast on Demand customers can use the service. Cable on demand is not like satellite on demand. They truly have servers in the headend like a big TiVo machine. The viewer can watch the show whenever and as often as they want and have pause, fast forward, and rewind capability. Having said all of this, I believe that I would still opt for the TiVo option.
Ah. Well, you see... that's the problem sir. We've located the end of the universe. The problem is that it just passed Alpha Centauri and should be here early next week.
So why don't you drop cable and move to satellite? Oh. Wait a minute. They require a proprietary set top box for every television just like cable. Never mind.
And maybe I don't want them to be able to audit what I'm watching. And no, I don't like that they can do that with my cableboxes now.
I realize that everybody hates the cable companies and they believe that thay have black vans that drive around and collect data on what they are watching. I'm here to tell you that this just isn't true. I am pretty well connected in the industy, and as far as I know, there is not one cable company in the US that is collecting any viewer data from Cable Cards, Cable Boxes, or Vibrating Pictre Windows.
In the case of PPV or VOD, they have to collect data so that thay can bill for the services, but even Subscription VOD and Free On Demand views are not tracked beyond collecting a count of views of a title.
I realize nobody here will believe me, but the cable companies really do go out of their way to protect subscribers privacy.
That's the problem with unicast protocols. What you need to do is recruit a friend an have them stand on the other side of the room. Their job is to catch the hard drive. This protocol addition to your network will greatly reduce the chance of data loss errors.
Also, you might consider a 300GB drive to increase network throughput.
Most Mac users are professionals and are reasonably aware of the dangers of downloading and executing evil software. If the Mac had as large a base of clueless users as Windows does there would be a lot more evil stuff targeted towards them. There's just no good reason to spend a lot of effort targeting Macs.
Does that mean if it hits 81.8%, the 49.99% who voted for the loser will seceed from the union and start a civil war? Now that option on the/. poll makes sense.
Actually, I would have thought that a section on how to best configure MySQL for particular performance situations would have been very helpful. I have not read the book, so it may very well have such a section, but this posting implied that configuration was assumed to be a non-advanced topic.
Actually, the computer price is quite reasonable. It's the nuclear power plant to supply the 21 million jigawatts required to run it and its cooling system that will set you back big bucks.

So, in lawyer school didn't they teach you that "completely and creatively wrong" means the same thing as sarcastic?
