Not really sure why some one would choose to use AA batteries on a netbook.

puns• 17 years ago

Quote from the article: "This allows the Gecko Edubook to be easily configured to the end-user's requirements and gives the opportunity the Edubook to be assembled or retrofitted locally. These batteries can be easily sourced and replaced as required."

I think the main advantage is that these batteries are cheaper and easier to replace.

And you can get generic rechargeable batteries from a variety of manufacturers.

Edit: Or a battery pack like described in the article.

axod2• 17 years ago

Same reason you buy a digital camera that takes AA's. So as when they run out, and you're away from home, you can pick some new ones up from any shop.

I bought a netbook lately, Asus Aspire One. It cost £179, and a new/spare battery for it costs £80. That's just obscene.

edit: ACER Aspire One.

chanux2• 17 years ago

I think your machine is Acer Aspire one :)

hyujiok• 17 years ago

And imagine you are using the machine in an industrial app and you need it to work in 5years time. How much will they charge you for batteries then when they are the only source?

That's why we pay so much for Psion handhelds now

The AA is the closest thing to a generic battery. I often work in remote locations and more of my gear (also including cameras/sound equipment) that runs on AA, the better. A UPS style big battery with outlets is a worthy alternative, but they typically weigh 30 pounds, you have to keep track of more cables, and can attract suspicion from airport security. I'd way rather have a few hundred AAs - yes, I do recycle batteries, and use rechargeables, but in a work environment you just want to be able to grab fully charged ones, fast, even if that means recharging said few hundred after the job ends and you get home.

On a more general level, I like it that they've designed the RAM and CPU slots to allow easy upgrades. At a $200 MSRP, I would certainly get one (or even if they drifted up to $249). The specs are very good for such a small machine and I wish them every success with it.

Why wouldn't you? Most laptop batteries -- with the exception of some of the most recent ones that use LiPo packs, or some very rare designs using prismatic cells -- are just plastic cases built around commodity cylindrical cells.

Here's a photo of the inside of a Dell: http://electronics.howstuffworks.com/lithium-ion-battery1.ht...

It's pretty trivial to build the charging circuit into the device and let the end user swap out the cells directly, but doing that gives up the obscene margins that manufacturers charge for replacement batteries, and (although I don't buy this as the actual reason) might conceivably lead to more damaged devices due to users swapping cells improperly, reversing the polarity, or mixing cell types.

of interest in the modularity of the chipset itself. why throw away the screen and power supply when you can upgrade by replacing the main board?

cmos• 17 years ago

What they are trying to do is build the 'ibm pc' of laptops. If they use enough off the shelf parts that are somewhat standardized (or open enough to make into a new standard) it could be a platform that takes off.

(though the market demand for such a platform is probably more aligned with people having to maintain large numbers of laptops than the casual consumer)

DTrejo• 17 years ago

I'd say it is also more aligned with people in poor areas who find it cheaper to upgrade, rather than replace.

If history taught us a lesson, next step will be solar powered netbooks.

In order to do that all you need is to get rid of power consuming devices like HD, DVD etc and just leave a motherboard, memory, SSD and a low consuming display.

ryanwaggoner3• 17 years ago

I must have missed that history lesson...what consumer electronics are solar powered, other than perhaps those cheap calculators?

TweedHeads2• 17 years ago

"other than perhaps those cheap calculators?"

Read about the history of calculators to understand their evolution.

Since the abacus...

Also watches? I'm skeptical on the idea but the math seems to be reasonably close as to justify hope.

Suppose the notebook's lid is 20cm x 30cm, direct sun light is 1000wt/m^2, so we're getting 60 watts of energy per lid. Best solar cell efficiency available today is 20%, with 40% in the works (it takes very long time to make stride though). So, we're looking at 12w today and 24w in the future.

This is not entirely outlandish. Moving parts can be removed and silicon parts can be optimized for smart power management (e.g. sleep some regions of RAM, some parts (cores) of CPU, shutdown some SSD controllers while keeping others etc).

The only big thing left is the screen. Latest 2.2" OLED screen works at 100mw. http://www.treehugger.com/files/2008/08/tmdisplay-oled-scree... So this screen is, (2.2 * 2.54)^2 * sqrt(3)/4 = 13.5 cm^2 and to cover a big 20x30cm screen we need 600/13.5 = 44 such small screens, and they should consume 4.4watts total. So the screen problem is manageable in the long run.

This can be made to work, at least in sunnier climates.

I would probably expect cell phones to get there first, however. the technology is expensive (both OLEDs and solar cells) and ARM&cell phone companies have better expertise in deep power management.

anigbrowl2• 17 years ago

I'd rather a cheap general purpose solar-panel/ crank-handle/ battery combo. Or those bags I've been seeing recently with solar panels worked into the flap. You can't depend on the back of the screen being pointed directly at the sun enough of the time. In hot countries you might well want to get into the shade before sitting down for an hour.

It's nice when traveling to have electronics that all runs from AAs.

AAs can be found all over the world. And, if all your stuff runs the same battery, you can swap them between devices in a pinch. This computer looks awesome.

brfox• 17 years ago

It looks exactly like an Asus eee PC. Is this some sort of retrofit or something?

blasdel• 17 years ago

I have a 15-year-old Gateway Handbook 486 that only takes 5~6v at well under 1A (with a hard drive, much less with a CF card). It can run forever on 4 AA NiMH batteries, or from a USB port!

Unfortunately, the screen is total crap -- I don't mind that it's grayscale, but that it's an ancient bottom-barrel passive screen.

Ah, NorhTec! Quirky little Asian/Canadian company. They do lots of interesting simplifications like this. A few years ago I was seriously looking at filling a datacenter cabinet with 200 of their 5W microservers.
