[Arm-netbook] "recycling not the answer"

[Luke Kenneth Casson Leighton]

if the energy cost of the plastics injection molding is enough to
power a 30 watt laptop for 1,000 days (3 years), then clearly,
recycling of the plastic, doing exactly the same thing, is *not* doing
the environment any favours.

the answer is, (a) instead, to keep that plastic casework in use for
as long as possible (for example by allowing the main processor and
memory to be continuously upgraded on a rolling basis) and/or (b)
develop different casework production techniques that are far more
energy-efficient.

I don't see where in the article it states such a cost. I does mention
pretty much exactly this cost when talking about the price of the memory
chips, IIRC.

i'm not so concerned with precision, on this, just the general
principle and that someone has done the research, and found out such
estimated costs.

something like that, yeah.

But whether this cost is in the injection molding of the case, or in the
memory chips makes an enormous difference for your project, since the
memory chips are on the CPU card.

both (casework and cpu card) are long-term re-usable, because the
main base unit may be upgraded on a continuous basis, and the cpu
cards may be put, ultimately, after being re-used for many other
end-user purposes, finally into alternative products such as routers,
3d printers, NAS storage boxes, low-power co-located servers [1] and
so on.

so in both instances, the lifetimes are extended, making it a much
more responsible strategy and also allowing people to save money.

[1] google "raspberry pi hosting" and i think you'll agree that the
idea of co-location sites putting out a permanent ebay automated "buy"
order for unwanted EOMA68 CPU Cards is not unreasonable.
