I remember reading years ago about how phages were being investigated for use in nano-technology, if i remember correctly they were planning to use phages alter bacteria to create the basic building blocks for nano machines.
I'm fairly sure people have been genetically engineering these things for about 10 years now
These have been around for years at a fraction of the price.
Screws on to pretty much any drum stool.
Even considering the amp you would need to buy it still comes in at well under half the price.
If I'd known you could charge £500 quid for a silly name I'd have been on this ages ago.
Heat exchangers come in all types, the ones on fridges just happen to be air cooled. Industrial building chillers use water as the medium to be cooled this cold water is then pumped around the building and used in small heat exchangers in each room, the warm water then being returned to the chiller to be re-cooled, thus saving tons of refrigerant.
A similar principle can be used for chillers that are located in basements, where the condenser part of the chiller has cool water flowing around it that absorbs the heat from the condenser, this warm water is then pumped to the roof where it is cooled through evaporative cooling where by water sprayed onto a coil containing the warm water is evaporated by large fans blowing over the coil thereby cooling the water inside which is pumped back downstairs to be used again.
(cooling towers are not always used, most beer coolers just have a coil with water flowing through it that is passively air cooled then fed to the condenser of the unit indoors)
The condensers for fridges generally kick out temperatures of around 40-50ºC which would be ideal for preheating water for showers etc the problem would be the need for cooling of the evaporator when showers aren't being used, so you would need an alternate method of heat rejection when no hot water is being used (cooling tower?) so it would be possible but not practical.
Legionella is not really an issue as all the water in the heat exchanger is contained in a sealed system, the problem comes from the cooling towers which are an open system and need to be treated regularly.
The problem with evaporitive cooling is that the amount of cooling achievable is limited by two factors, the ambient temperature and the humidity of the air for cooling the cooling towers, for example, air at 25ºC and 100% humidity would only be able to cool to 25ºC as there can be no more water held in the air hence no evaporation and no extra cooling, air at 25ºC but 50% humidity may be able to cool to 20ºC (i can't remember the exact maths i'm afraid) as evaporation aids the cooling (think of wind on a wet finger)
Sorry for the lengthy post
Apparently they actually used 540Gev according to their own front page.
The #LHC accelerated a beam to 540 GeV overnight. Here are the pictures http://bit.ly/4Njuxf. #CERN

I just wanted to mention that for those people who use it, OpenDNS has been blocking the Confiker call home address' for weeks, they will also show in your dashboard if any machines have been attempting to call home.
@ Ben Rose
Exactly what i was about to say.
I initially assumed BT wanted acess to the Actual fibre which would be wrong as Ben pointed out.
However using ducting that already exists surley makes sense for everyone. Virgin get a fat check BT get a backbone network at a fraction of the time/cost and we dont have all the streets dug up... again
Except maybe for virgin who lose a slight competitive edge.
Laser light operates in the 0.4μm to 10μm wavelength range, i would imagine that they would modulate small bands of these wavelengths from one laser source split into the appropriate wavelengths (by the waveguides?) then modulated individualy, then recombined and transmitted to wherever they are going to, then decombined again back into there respective wavlengths where the data is read.
But that's just my guess
To be honest i wouldn't want to smoke Kevlar either.
The Last Thing...
... the universe will ever hear is "i wonder what will happen if i push this...."
"But, er, if those numbers are to be believed, then Microsoft runs about 8.5 servers per rack, which seems disheartening in this day and age of bladey goodness."
Depends which are you look at, assuming that both sets of data are sorted alphabetically which they appear to be if you match overall server count with Kw consumed in the two screen grabs.
They appear to show that for example Columbia has 37,230 servers in 2,550 making 14.6 severs per rack on average, however Dublin has 1,209 servers in 318 racks making 3.8 servers per rack.
Interestingly if we take these figures and combine them with the utility power consumed we see that Columbia uses roughly 300W/server and Dublin is running at 950W/server???.
i have to say that 950W for a server seems a little high so maybe i have fudged something along the way, although if you check out Amsterdam they come out at a thoroughly respectable 288W/server.
Can a server consume nearly 1Kw? do these consumption figures include operating costs, i.e lighting, air con etc.
The only one
I can't be the only one who thinks this would be really funny, assuming the parties involved didn't trash the place.
With a bit of respect on the part of the kids this could work.

"Anyone with any sense can clearly see that Opera 9.5 is far superior in every aspect to Firefox3, just not as much hype"
Well for me on OSX 10.4.11(MBP 2.4Ghz 2Gb ram) Opera is being kinda sucky, after loading approx. two pages the browser will just show a blank page which i have to refresh to show the page content.
I have re-downloaded Opera and trashed all the prefs to no avail, i accept this may be isolated however ALL my other browsers work fine, and FF3 is pretty goddamn snappy.
Not saying anything against Opera, i've used it before and its great, i'll just use whatever works best for me at the time

De-mobilizing my ass!i discovered exactly the same thing when i was a kid, the capacitor for the flash will give you a nice little jolt and maybe a numb arm at best.
The only chance of demobilization is for the person with the "Taser" when the get a quick slap for shocking the wrong person.
