the whole "max torque from 0 rpm" phrase that is thrown around is quite misleading. While true that a motor exerts its maximum torque at zero rpm (and drops linearly as rpm increases), it also has the worst efficiency. maximum power draw (it's a short circuit!) and minimum power output (it's not moving is it?). peak efficiency is at a specific rpm, thus a gearbox is needed *for efficiency*.
to put 8 kW/kg into perspective, all commercial brushless dc motors are at 4 kW/kg and it is a limitation of the materials used.
Commercial internal combustion engines range from 1 kW/kg to *maybe* 3 kW/kg if it is turbocharged to the point of sacrificing engine longevity and formula 1 engines are at around 5 kW/kg
although i suspect they saved weight by using the vehicle frame as (part of?) the stator, a perk of making a motor for a very specific purpose.
going off on a tangent, whoever is responsible for android's ui needs to be tortured.
no clear indication of accepted taps, no indication the device is busy, no way to distinguish interactive elements from eyecandy, menus needlessly hidden even on huge devices, pointless separation of menus (eg: why are there two menus with different styles in youtube?), elements abruptly changing location whilst being active (you tap somewhere but at the last fraction of a second, the list refreshes without warning and now you must guess what you've tapped), message windows pop up just before you tap something completely unrelated but since you've already tapped the window disappears and now you will never know what it said, i could go on.
my 1997 hp48gx has immeasurably better engineered UI.
someone explain to me why each newer version is progressively slower on the same hardware as time goes by? If we were to believe the continuous performance improvements, this thing would hit 120 fps on a 286 by now.
Why does the FBI get involved? is it because the events span multiple states, or because the banks have so much clout? If this had happened to google or microsoft, for example, would the FBI get involved?

A clutch isn't really necessary, i'd guess.
and it will get floated every couple of years until they figure out how to make it worthwhile

you do realise the absurdity in what you suggested, don't you.
can you think of a way to do those tests with less cost?
but to see them actually go for it? ... the poor bastards...

*tortured* i say.
If you have the patience, can you please give me a short explanation how to read the chart? Thank you in advance.
... do you have a source?
"They want to consume more than they produce"
if you were familiar with what the EU *forced* us to do when we entered the euro, you wouldn't say this.
they basically paid us to stop exporting.
there doesn't have to be a provision
they can just make it so the greeks will wish to leave the eurozone.
no not any more promises for free or cheap stuff no, this is what earlier greek gorvernments promised
"there is money" etcetc
no for fuck's sake no NO GOD NO
what greece needs is for the greek people to finally FINALLY learn how to work EFFICIENTLY and manage their finances
Not sure if anyone agrees, but it seems simple enough to me.
Where are the really high power ARM architecture computers?
Isn't there anything that can compete with current x86 processors?
I'd very much like a normal desktop computer with an ARM cpu.
cubieboard 1 and 2 have sata ports.
cubieboard 3 aka 'cubietruck' doesn't.
the other one i've found is "TS-7800" on here http://www.embeddedarm.com/pro...
poor performance on hardware nearing 10 years old
who would have thought
in unrelated news, my hp48gx can not run crysis.
it better switch to desktop mode when i plug in mouse+keyboard on my Z ultra.
i feel steam is horrible in this regard.

"monumentally" ranks higher, imho

Isn't it possible to sideload siri in an earlier phone model?
yeah, no thanks. After having been burned horribly by ocz, i'm not touching anything carrying their name, no matter who actually builds them.
