greenflying the internet

so this post recently on greening the internet (a popular topic since I promoted accepting a paper at sigcomm a couple of years back which lots of others didnt seem to want then:)
is partly wrong

a couple of problems here
1. optical isn't cheaper powerbudget necessarily - lasers take a lot of power and
dissipate a lot of heat needing a lot of aircon -
2. decentralising resources (e.g. into people's homes) removes need for aircon
which reduces power needs and means a lot of requests can be satisfied locally
reducing load on net, reducing net power budget
3. people dont like putting resources in central sites - attacks,
latency, ownership, censorship and other problems abound
4. the issue isn't the price of power, its the nmber of KWatts -
one obvous thing about putting resources in everyone's home is that everyone needs hot water, so one can
use heath exchange to cool computer to pre-heat water - this sort of thing is very good karma
and cheap technology...

so i disagree with the blog!!! in fact, i take a diametrically opposed viewpoint.

but thanks to bill for posting all the usual useful stuff at
his canadian net news site
