Recycling Excess Heat From the Data Center

itwbennett writes "A new data center being built in Helsinki, scheduled to go live at the end of January, will generate energy and deliver hot water for the city. The data center is located in an old bomb shelter and is connected to the Helsinki public energy company's district heating system, which works by pumping boiling water through a system of pipes to households in Helsinki. The recycled heat from the data center could add about 1 percent to the total energy generated by the energy company's system in the summer." The article doesn't say what the overall efficiency of the heat recovery is. Researchers at MIT are working on a new energy-conversion technology based on quantum dots that they say has already demonstrated 40% of the Carnot efficiency limit — 4 times what is achieved by current commercial thermoelectric devices. The researchers believe they can reach 90% of the Carnot limit.

Valium and Xanax for Engineers and Physicists

The pump is also very efficient -- you get five times the amount of energy you put in, he said.

So, engineers and physicists, when you see statements like that, how do you cope:

1. Stiff drink(s)
2. Xanax(s)
3. Dust off plans for your perpetual motion machine company to go public
4. Cry yourselves to sleep.
5. Other

6. Post condescending comments on a forum that no one will read.

That's good

"The Internet is not a big truck. It's a series of tubes. And if you don't understand, those tubes can be filled and if they are filled, when you put your message in, it generates more heat and it's going to be delayed by anyone that puts into that tube enormous amounts of boiling water, enormous amounts of boiling water."

What about the exec office?

[filesiteguy]

Now that we have the issue with the heat coming from the server room solved, let's tackle the hot air coming from the executive offices next.

Any ideas?

Re:WTF, why is a Carnot reference here?

There is NO WORK being done.

You know way too much about computers.
