Two excellent points and something of a concern in our home. We are a
very environmentally friendly household, recycle everything : paper,
cans, plastics, grass cuttings & dead vegetation, batteries, old pc's
Our bin only goes out every 6 weeks - saving a fortune ;--)
Now we, sorry, I fail _miserably_ on electricity usage. Two aquariums
with outragous filters, lights, heaters running hot (30 degrees for
discus) - not even counting the pond ones.
Then there's the three pc's, two are always on (one headless "server",
one a TV, and one gamestation)
Does having so many services on one box add security worries?
I've considered buying low power setups, but the wife would go mental if
I brought home any more kit. We are trying to acually _save_ money, a
concept I dont seem to have grasped. So I'm waiting for one box to die
I would image that switches and routers would use very little power, and
I am entrigued by your suggestion of compact flash.
Have you implemented this Padraig?
I would welcome comments from anyone who has done so.
Its gotta be cheper than my other mad idea - investing in a 5 grand
solar panel for the roof. Really got to grasp that savings concept!
