First Dutch homes heated by computer servers



We’ve just posted the following news: First Dutch homes heated by computer servers[newsimage][/newsimage]

The Dutch start-up Nerdalize and electricity provider Eneco have started a pilot to heat homes with computer servers called eRadiators. When the eRadiators are calculating, they generate free heat for homes.

Wow, a most ingenious idea. Whatever will you clever Dutch think of next. :clap:


I suppose these servers will have to be plugged in to the homeowners’ internet connections. If they use an excessive amount of bandwidth, will that mean the users will be unable to use their own high-speed connections at a reasonable speed?

How about computers that don’t produce excessive quantities of heat?

They’ve been working hard on that for a while. Modern processors - even those aimed at servers - are far more power efficient than those of a decade ago and continue to improve. And the energy saved is multiplied by the fact that server rooms are normally air conditioned and which requires even more energy to remove the waste heat.

But alas room temperature superconductivity is still many years away (if it is ever possible). Great progress has been made in high temperature superconductivity over the last 30 years, but in this field ‘high temperature’ is relative. A record high of 138 Kelvin was claimed 22 years ago but remains unconfirmed, but even that is a rather impractical -135.15°C.

So for now, putting the waste heat they inevitably generate to good use is much more practical than attempting to circumvent the laws of electrodynamics and thermodynamics. :wink:

Superconductivity was a Dutch discovery - Heike Kamerlingh Onnes at Leiden in 1911.


Power consumption of servers has indeed dropped quite significantly over the last few years, with lower power requirements from the CPU, and the adoption of SSDs replacing HDDs.

However, the consumption of us consumers for ever more data bandwidth, means they need more servers to meet our demands.

It’s good to hear that all that heat the servers produce are being put to good use.


A full-spec Xeon CPU with 14+ [I]physical [/I]cores, running at a similar clock speed & TDP to a single core Athlon 64 of a decade ago is an astonishing achievement.

And that’s before factoring in the huge improvements in processing efficiency per clock cycle.

Hard to believe this is the same company who spent 5 years trying to flog us the dead horse which was the Pentium 4. All processors produce heat as a by product, but it sometimes seemed like the Pentium 4 was a heating element with processing as the by product. :rolleyes:
