I think Sugar on a Stick, especially the way we are going technically where you can use either LTSP or a stand alone computer with the same stick is a very green solution. LTSP saves electricity. Extending the life of old computers keeps them out of landfills and saves the power and resources used to make a new computer. At the Gardner School the computer lab is used pretty much all day and all afternoon. Call it conservatively 8 hours a day, the school is actually open 7am to 5pm at least. There is 180 school days plus 30 days of 8am-5pm. So lets say 210 days x 8 hours = 1680 hours/year. If a kid has a computer at home they will use it less then 8hours a day because they are mostly out of the house. Does anyone have any data on how many hours per day kids use their XOs outside of school? I'm going to make a guess at an average of 10 hours per week x 52 weeks per year. So that is 520 hours/year. Thus energy effieciecy is 3 times more important in the school computers then for the computers the kids use at home. If a school is in a warm climate and is air conditioned it becomes even more important. Thus as a school gets money for new computers, first it should goto LTSP for high usage computer labs and move older computers in kids homes and low usage areas. No idea what is better from the environmental POV, but from the organizational one may be great to associate with some of those NGOs that recycle computers in urban centres for redistribution in their area. It may not be easy for them to explain to some parents why having a computer at home is good for their kids, but if it was included in a bigger initiative involving also schools and SLs, that may give an extra push to their vision.

I think Sugar on a HW is wildly over the map in environmental efficiency and risks. The software is almost incidental -- at its best it can help HW designed to be efficient achieve its design goals. I can't do much with HW that is not designed for it. I can't do anything with HW that is laden with environmental risks. So I don't think much of a statement can be made in terms of environmental impact :-/ -- OTOH, the HW is a complement to Sugar... maybe we can publish 'environmental impact assessment' howtos, charts, procurement guides, etc. Same as you'd do with any other complement to your product. cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ IAEP -- It's An Education Project (not a laptop project!)
