As a mechanical engineer, I'm not exactly cynical about this application of Eneco's technology, but I remain very, very skeptical. With such a relatively small temperature difference, I would say it is very unlikely that such a device would be economically feasible. A quick visit to Eneco's site shows me that they don't even have lab data for temperature differences of less than 100 deg C!
They obfuscate the issue of efficiency by referring to the Carnot efficiency to inflate the numbers to the uninitiated. Sadi Carnot showed that an ideal heat engine that operated between two infinite reservoirs at temperatures, T(hot) and T(cold) would have an efficiency of ( T(hot)-T(cold) ) / T(hot), and the temperatures have to be on an absolute scale like Kelvin or Rankine. The "Carnot efficiency" compares the performance of the system in question to this ideal heat engine.
Suppose you ran your chip at a very warm 90 deg C (363 K) and could dump the heat to your 25 deg C (298 K) room, your perfect efficiency would be about 18%! This means that for every 5W of heat you dissipate from the chip, you get a little less that 1 W of electric power. Something with an impressive-sounding 50% Carnot efficiency would really have a measly 9% real efficiency.
Unless Eneco sells these things very cheaply and makes them very small, I can't see Apple going through the trouble and expense of adding them to their portables for such a small benefit in recycled power. I remain skeptical, yet open-minded.
Finding efficiency data for temperatures below 100C would be important since the max junction temperature for most processors is below that. Power supply devices max out at about 150C. You just can't get hotter than that and expect silicon to function as a semiconductor.
If the Intel chips burn 100W, then 9% conversion efficiency would generate 9W of electricity. In absolute terms, that's not too bad. You can do a lot with 9W. If you have a 5 hour battery life now, and can use these on all the major power sinks, you'd get 5.5 hours of battery life.
(Those are big "if"s, but putting them in bold seemed a bit too cynical...)
Interesting, but not earth shattering yet... If this became widespread though and we could cut world energy consumption by 10%-- that would be a big deal. Personally, I think there's more to be gained in cars (hotter and less efficient to begin with) than computers, but who knows.

Sure, but how much "iDisk" space are they offering? ;)
I get 1gb from Yahoo for their "Briefcase" which is online storage.
You can easiliy convert a Gmail account in to online storage. So that's 2+gb of online space as well.
AND, you can use mediamax (or numerous other online storage sites) which I mentioned above for 25gb of free online storage.

There have been many intel gpu based machine that had 1600x900 res displays, like the C2D Vaio Z or some of the offerings from Lenovo. I don't see why apple can't give such a res with to the 11.6in MBA with a 350nit display and wide color gamut. Then just add and SD card slot, make the usb ports 3.0 and a maybe even add a thunderbolt port and I'd be the first in line to get one.
Core 2 Duo based VAIO Z's had an NVIDIA graphics chip for light gaming/HD videos/GPU intensive processes and the Intel graphics were only for basic processes like Word and internet surfing.
In the Air you would be stuck with the Intel gfx doing everything as there is no space for a dedicated chip.

And there's something about Steve jobs drinking Starbucks coffee that doesn't sit right with me. I don't really know why.
It's not starbucks they were at: Calafia

"warfighters"...ugh.
I disagree.
Whether you like the military or you don't, if we want them to survive on the battlefield it's important that they have the best equipment possible. If in some case that were an Apple product, all the more power to them if they want to buy it.

That's really interesting! You just held "c" at boot to load up the XP CD?
I'm guessing you still needed to use a "slipstreamed" XP SP2 CD with the SATA drivers installed so it doesn't run in dog slow PIO mode
Where the hell did you find chipset drivers, graphics card drivers, sound card drivers etc? :confused:
Clarification:
I made a MacPro driver CD from Bootcamp, and a slipstreamed XP SP2 CD. The slipstreamed XP SP2 CD boots up just fine holding "c" at boot.

Damn Early for x86 only mac software!
This is to be expected. Apple sold 680x0 Macs right into mid-1996, but support for the chip was even disappearing from mainstream stuff like Netscape by 1998.

Anyone know if the video card in MBP 13" will be acceptable. When I saw acceptable I want some what decent performance.
Acceptable you saw? Sure.
Who needs to be specific, huh.

I am JB and have biteSMS. This is the reason the new version won't work? I'm logged in but everything keeps popping up 'Error' on every page.
Is the only option to restore the old one by syncing with iTunes on my computer?
yes this is the reason. try it yourself.
and yes. i updated FB on my phone. so i just deleted it, and then re-sync'd my phone with the older version of FB.

Really nice for the schools.
Really irrelevant for the schools. I can't say this will change our purchasing strategy in this area either way, the discount is too small to matter really.
It's up to innovative schools to decide whether, and how, iPads have a role in schools. They might have good uses in classrooms, libraries, labs, reading clubs, alongside computers, instead of computers, or who knows.
Except they don't support things like Jmol. They're too big to go into a pocket, they can't be shared around like books, they'll need recharging if they're used heavily. The ipad is a lot of things, sure, but there's lots of things it isn't, too.
Who cares??? its a $500 device that can replace all computer needs of any student. Period.
I bet my students can't wait to run products like AutoCad, Final Cut Pro, Logic, Sonar and Visual Studio, on the ipad. They'll be so excited I'm sure.
It's just a glorified web slate and note taker. By no means bad but I don't see any students where I work, or staff for that matter, rushing to get one. We may buy one or two for R&D.

The iPhone 4 sported twice the RAM of the iPad. Perhaps the iPhone 5 also sports more RAM than the iPad 2.
In fact, maybe that's part of the reason for the push to September. To put more distance between the iPad and the iPhone so that iPad owners don't feel like their product is playing second fiddle to the iPhone (which it is).

I wonder what this means for being able to install virtual servers on Parallels and the like?
For one thing it will be cheaper. Family Pack vs having to pay $500 per copy. I hope Apple doesn't cripple it.

Except race has been shown to have an effect on intelligence. Ashkenazi Jews are about 1SD above whites, on average (average IQ 100, SD = 15). Blacks typically fare about 1SD lower than whites.
You should start with The Bell Curve: Intelligence and Class Structure in American Life (http://www.amazon.com/Bell-Curve-Intelligence-Structure-Paperbacks/dp/0684824299/ref=sr_1_1?s=books&ie=UTF8&qid=1302676401&sr=1-1). The authors explain it far better than I could.
Where do East and South Asians (not SE) place, +1SD or +2SD?

The phrase Podcast didn't exist until the development of Apple's iPod so I don't see why they shouldn't own the rights to it or at least have some level of control for it's use.
