Agbogbloshie in Accra, Ghana is the world's largest dump for electronic waste from all over the globe. Meet the teenagers who tend it in this short film, Regolith, directed by Sam Goldwater. Read the rest
Server farms generate so much heat that they have to run air conditioning year round. That requires energy, which costs money and tends to mean burning more fossil fuels. Meanwhile, in winter, a lot of houses are cold. The people who live there have to turn on the heat, which costs money and tends to mean burning more fossil fuels.
So here's an idea: Why not distribute the hardware from a server farm, putting heat-producing equipment in houses that actually need the heat?

If a home has a broadband Internet connection, it can serve as a micro data center. One, two or three cabinets filled with servers could be installed where the furnace sits and connected with the existing circulation fan and ductwork. Each cabinet could have slots for, say, 40 motherboards — each one counting as a server. In the coldest climate, about 110 motherboards could keep a home as toasty as a conventional furnace does.
The rest of the year, the servers would still run, but the heat generated would be vented to the outside, as harmless as a clothes dryer’s. The researchers suggest that only if the local temperature reached 95 degrees or above would the machines need to be shut down to avoid overheating. (Of course, adding a new outside vent on the side of the house could give some homeowners pause.)
According to the researchers’ calculations, a conventional data center must invest about $400 a year to run each server, or about $16,000 for a cabinet filled with 40 of them.
