Apparently you haven't been keeping up with battery technology. Toshiba's SCiB charges in 10 mins. Been shipping for a few years now. Other researchers have reported similar capabilities in the lab.
That's a secondary question. The capacity and charge rate of the specific vehicle/battery will of course affect charge time.
However, the capability of the charging system/connector puts a hard limit on all vehicles, thus it becomes the critical limit for designers of new vehicles.
And just like most self-righteous jerks, you have a problem with reading comprehension. Check again, I never said the discontinued the iPad 2. I know they never discontinued the Wi-Fi version, but I thought they had discontinued the 3G versions. I was wrong, caught my own mistake, and posted a correction.
And you have no clue who I am, or what I know. And you come back with that BS. Stick your attitude.
Rather than fight a standards war, they'll likely adopt this for the US and European models. Having the charging infrastructure is more important than the specific charging system.
8MW is a measure of power, but it's irrelevant to the question at hand. Gas powered vehicles waste most of the energy in gasoline. Heat, friction, conversion efficiency, etc. So the theoretical power flowing through a fuel hose has only an indirect relationship to the amount of power an EV will require to theoretically be able to "charge" as quickly as you can refuel.
Which is exactly why I asked the question. How much power can it deliver in 15 minutes? It will have maximum voltage and amperage that the connection is capable of delivering, yielding a maximum power it can deliver, yielding a maximum energy it can deliver. And the commonly used unit for measuring electric energy is KWh.
So again, how many KWh can it deliver in 15 mins? Everything else is secondary.
Valid question. But for something like the Volt, they only operate the battery from ~30% capacity to 80% capacity, which means you can fast charge a "full charge". Most batteries don't have to slow the charging until somewhere over 90% capacity.
Better question is how many KWh can it deliver in 15 mins? Since vehicle battery capacities vary significantly, that's the relevant question.
I've misunderstood nothing. It appears that you didn't actually read my blog, or that you've completely misinterpreted it. If you read my blog, I think you'll find that we basically agree.
The idea of "free markets" as espoused by most people is flawed. They don't exist, because they can never persist. They don't account for human nature. Greed, corruption, and the pursuit of power will destroy any free market. "Market forces" are not always sufficient to keep those in check. Therefore, there must be some level of regulation.
Rather than post lengthy explanation, I'll refer you to my blog post on the topic.
Except that they don't explode, they burn. Lots of energy, but it can't be released fast enough to actually "explode". While the same is true of liquid fuels, if you can vaporize or aerosolize those fuels, they can become explosive. See "internal combustion engine" or "fuel-air bomb" for examples. They can be dangerous, but they're not as dangerous as a fuel tank can be.
Most likely because they got rid of Elop. Of course, Sony has been doing their best to run off PS3 customers. Which brings up and interesting question; did Sony hire a former MS exec a few years ago?
IPv6 isn't even available everywhere yet, much less widely deployed. So, yes, it is absolutely necessary to have directory nodes. They used to co-opt user machines for that purpose, now, they've allocated dedicated servers in data centers with high availability and high bandwidth. That's an improvement anyway you look at it.
Obviously, you didn't RTFA, but that's the norm these days. The traffic doesn't go through the supernodes, all call traffic is p2p. The supernodes are directory servers so that clients can locate other clients.
But units wouldn't need to be labeled if everybody used the same system. The continued existence of the zombie Imperial system is the root cause of the problem.
Flawed logic. Units always need to be labeled. Here's a metric length for you 5.5
You know it's metric and a length, therefore, it's in meters. But is is nm, mm, cm, m, km? Without labeling, you have no idea what the units are.
Unless you want to eliminate all the si prefixes and list everything as decimal gm, m, l, etc. Of course, that's as absurd proposition, making your statement absurd and incorrect.
At first, I thought this sounded like a stupid idea too. Then, I read the spec. They're not just changing the width of the equipment area, and it's not just an extra 2".
External width is unchanged from the 19" rack standard, it's still nominally 23.6". No replacement of floor tiles or room redesign necessary.
Equipment width is increased from ~17" (on a 19" rack) to 21", it's allows 4" wider equip.
Power is handled in 3 "zones" per tower. Each power zone provides 12.5V DC power on each of 3 independent pairs of power rails, No AC power supply is required for each piece of equipment, but they will need DC-DC converters and VRs to supply the voltages needed for their specific components. That saves some space on each device, and provides a slight improvement in efficiency. Because this is standardized worldwide, there is no need for each device to have different power circuitry for different countries.
Because a zone can have triple power rails, devices can use 1, 2, or 3 power rails to provide whatever level of redundancy is appropriate.
Space for switches is included in each rack, along with power monitoring/reporting circuitry per rack.
Battery backup power can either be built into the power supply for each zone, or supplied from a separate battery rack.
The specification allows for many AC or DC power sources, this is the only significant part of the spec that will vary by country as the power units will need to support the available AC and/or DC supply.
All devices are to be hot-plug compatible.
So, it does have a lot of advantages.
Here are the concerns I have with it:
All power rails appear to be exposed. While they are on the back, this could be a significant safety (personnel and/or fire) issue. Considering that you can up to 500A @ 12.5V DC running through the zone power rails, and potentially more for the main cabinet DC power rails, exposed seems like a bad idea.
The standard allows depths from 36" to 48". With the way devices connect to power rails on the back, it looks like this means you will need to use devices designed for the specific depth of your rack, or use a shim to extend the device to match the depth of the rack. I believe they should standardize on one, or at most 3 depths, and have a standard set of shims to connect the devices designed for the shorter depths to fit the deeper racks.
80% of users don't need a high performance GPU, and in fact won't benefit from one at all. I'm an example of such a user. I can always use more CPU speed, but I don't even own any software than can get my laptop's discrete GPU anywhere near it's potential. And, since I'm on a 4.5yr old machine, even the HD 3000 graphics in Sandy Bridge would be a significant GPU performance increase, that still wouldn't be used.
But most importantly, if you look at the reviews, IB can maintain playable framerates at medium or high quality settings in most games. It's really only hard core gamers, or people doing work that can benefit from GPU acceleration that need a discrete GPU with SB or IB.
So, thank you for your opinion that is irrelevant to 90% of the market.
Presuming he messed with the wiring to accomplish this is recklessness. There is nothing in the video that requires more than wireless and plugging in to a power socket.
We'll never get to witness that, either Sol will become a red giant first, consuming anything that still lives on the earth, or, the gravity of the black hole with eat the earth before Sol succumbs. Either way, we'll already be dead.

Sorry, I was wrong. I thought they discontinued those, but apparently not yet.
No, less power, for a longer "run" time.
They don't sell 3G and CMDA versions of the iPad 2 anymore. If you want those, you have to buy used/refurb, or get a "New iPad" (aka iPad 3)

You seem to have forgotten a few missteps.
The Pentium IV "NetBurst" architecture. Dead end.
The P3 1.13GHz disaster. Unstable, and unable to keep up with AMDs chips.
The Itanic, er, Itanium, repeated delays, failure to perform to expectations, complete recall of first model, marketing failure, etc.
Larabee, or any Intel graphics prior to Sandy Bridge.
