For an equivalent RMS voltage, the power losses using DC are actually lower than AC - basically due to lower capacative effects. This effect gets greater at high voltages, so high voltage DC is very efficient.
One of the main reasons for DC in this circumstance is for phase matching - it compeltely isolates the AC phases at each end.
Someone mentioned earlier - he's creating a bulk material that naturally forms a variety of crystals - some of those crystals have better high temp superconductuivity than others. By doing the bulk resistance test, he can see small jumps when individual crystals start to contribute.
Later they'll have to isolate those crystals and figure out how to recreate them in viable quantities.
You've watched too many cartoons where people blow in their own sails. Why not skip the sails and shoot the laser out the back, same net effect with less losses.
Google uses custom trays fitted out with a 12V desktop motherboard & 12V SLA battery, and everything is velcro'd in place. The density is high, and the the cost is very low. They dont need expensive servers because they maintain redundancy at the "whole computer" level.
I would assume that since it's atmosperic oxygen reacting with the lithium, the thicknes of the resulting oxide layer limits the overall capacity. More surface area for the same thickness = more total capacity.
Also, many (if not most) people wont have the network capability to play cloud gaming. There are many days when my feed cant keep up with YouTube, and that's with dedicated ADSL. What about when I'm travelling or at a hotspot?
Considering it's a unicycle, I dont think so. From wikipedia:
"As well as moving forward and backward like conventional wheels, they allow sideways movement by spinning wheels on the front and rear axles in opposite directions."
You're right, not all men were affected by the attractive women. The others were gay and had buckleys chance of chatting to an attractive male in a lab.:)
If we could get the oxygen out carbon dioxide easily and leave us with plain carbon, there's no way we'd bothering with biochar - we'd be running our power plants on it
The whole point is that we gain energy by combusting carbon sources, turning it back to it's elemental form and burying it would cost the same amount of energy, if not more.
The Mars rovers have managed to drive around for a couple of years. Whilst I agree it's a pretty harsh environment, it must not be as abrasive as the moon.
Also Mars spacesuits dont have to be like on the moon. A flexible but tight fitting body garment (think wetsuit) is generally all that is required, with a pressurised face mask for breathing.
ISP arent shaping by port anymore these days - usually it's some other deep inspection techniques. There's no free/easy solution, and if you think you have one, the ISP's will have a countermeasure just as quickly.
Australia generally doesn't insulate (or heat) their floors, the winter temperatures just aren't that cold. The ground temperature is sort-of midway between the cold spring nights (just above freezing) and hot summer days (30 - 35 degC), so the ground is a moderating influence. In winter the cloud cover generally traps the atmospheric heat and overnight temperatures are much milder.
Most of the heat loss/gain is through the ceiling it's most cost effective to insulate there. A small portable gas heater is enough in winter, and a fan or airconditioner in summer.
"For our tests we use a combination of the onboard thermal reporting system as well as external inferred thermal testing equipment. Our reported temperatures below were the maximum detected temperature."
He should be taking the onboard temp sensor only as that represents the CPU. As other posted have said, a hotter heatsink (external) temperature for a particulat heatsink/fan combo is actually better beause it means that heat is reaching the heatsink easier.
Now, technically the onboard CPU should have always been the hotter of the two, but he didnt actually say this and it is a concern. Perhaps the infrared thermometer got reflections from other hot components off the shiny heatsink, eg the power regulator and chipset.

Yep. Same as like a static electric charge.
That's just plain wrong.

Huh?? RDBMS is a tool, not a solution. *How* will an RDBMS fix game worlds and servers?

But none would get funding for 22 in a million. I mean a million is such a big number, it wouldnt happen. ;)
Maybe 4 in a million makes people feel better. I mean, a million is alot bigger than 45000 isn't it!
Personally I think they just stuffed up converting imperial to metric somewhere.

I would argue that using a script to look for vulnerabilities is hacking (cracking), regardless of how foolish or trivial the vulnerability is.
It's clearly not actions of a normal / authorised user.
Umm..... I get your point, but the refrigeration on LNG plant would be about 4 orders of magnitude more powerfull than a data center.
Once you have low carbon grid power, it them makes alot of sense to move to electric vehicles.

Get a Linksys WRT54GL, flash OpenWRT onto it and then install the VPNC package. Instant VPN router and works a treat.
I run off one all day long, and use my work VOIP / PBX phone through it.
Feedback loops can have forward feedback components too.
Agreed, imagine bundle of these using 1.2GHz Intel Atom chips. Still very low power.
The distinction is usually intent. If you accidentally walk into a secret bunker with no intent, then that's not breaking and entering or burglary.
The analysis is somewhat flawed, here's why:
"For our tests we use a combination of the onboard thermal reporting system as well as external inferred thermal testing equipment. Our reported temperatures below were the maximum detected temperature."

Hahahahaha.... me too! Glad I'm not the only one :)
