Does Black Friday Contribute to Global Warming?

| by NRDC

The environmentalist mantra "live simply so that others may simply live" has been around for at least a couple decades.

But it hasn't had a discernable impact on the American consumer,
whose personal consumption spending has risen about 5% since the late
1980s, to 70-72% of our entire gross domestic product. (That's the
highest in the industrialized world; in Europe it's more like 50-60%.)

And the worst recession since the 1980s may not be stopping us. To
judge from this morning's newscasts, thousands lined up in front stores
around the country late last night, so that as soon as the clock ticked
over from Thanksgiving Day to Black Friday, they would be first through
the open doors to grab bargain-priced products out from under the
fingers of their fellow shoppers

In other words: I am American. Watch me spend.

This trend strongly suggests that taking only a morality-based
approach to curbing material lust won't shrink the average American's
personal avarice. So what about changing how we make things as well?

A revolution in manufacturing, called digital fabrication or
"fabbing," holds the promise to dramatically shrink the amount of
material and energy that go into creating and distributing our gizmos,
gadgets, and other objects of desire, without curbing their quality or

"You can't set aside fabbing" when looking at the next wave of
change in how we make things for daily use, says my friend and fellow
former Worldchanger,
futurist Jamais Cascio. "The compelling trend in manufacturing, looking
out over the course of the next decade, really does include an
increasing availability of local manufacturing, that is, the localist
movement taken to the industrial extreme."

A fabber
is effectively a small, self-contained factory that can take a
two-dimentional plan -- a computer file containing the design of a toy,
for instance -- and "print" it as a solid, three-dimensional object. As
the machine reads the plan, the fabber's small nozzle moves back and
forth, just like the nozzle of an inkjet computer printer. Instead of
spraying ink onto a piece of paper, it deposits tiny drops of a
quick-hardening plastic, layer by layer, until the entire object is

The plastic material used by fabbers to print objects can have diverse qualities -- there are even polymers that conduct electricity.
And these polymers can be part of the solution. "If you design these
polymers [and] printers the right way," says Jamais, "you can end up in
a world where when you're done with something, you essentially drop it
in the recycling bucket, and it gets broken down into the constituent
polymers that you can then use for the next thing you want to print
out. It's the ultimate cradle-to-cradle model."

Jamais believes that this is not just possible, but likely, and within the next two decades.

In terms of both size and cost, the technological trajectory of fabbers is closely mirroring that of personal computers. The hulking digital fabricators of a few years ago have given way to desktop-sized units, and while a ready-built fabber can go for $15,000, the mechanically-inclined can build one using open-source plans for around $2,300.

That's solid prosumer territory -- the product niche between the
professional and the casual user. And sure enough, right now the "maker" community of hardcore do-it-yourself technology enthusiasts is the group doing some of the most innovative work with fabbers and fabbing

"This is one of those of areas that is a sleeper, a sleeper trend
that has the potentital to be really transformative when it hits," he
tells me. "The challenge is getting the software to point where you
don't have to be expert in both Linux and in design to get it to work."
