Fast and complicated calculations are a product of fossil fuels.
Multiplying and dividing numbers was not always that easy. Before the
arrival of cheap electronic pocket calculators and computers
in the 1970s, people relied on an array of low-tech means and machines
to calculate taxes, profits or the properties of engineering parts.
Being an obsolete technology now, some of these 19th and 20th
century calculators are surprisingly sophisticated and fashionable.
Moreover, most are powered by a crank, which makes these gadgets
"green". Today's pocket calculators are no power hogs, either. The
thing is that computers took over most calculating jobs from
calculators, and a large supercomputer consumes as much energy as a convoy of trucks.
What do we do with all that calculation power?
We build fast cars, giant jumbo jets
and worldwide information highways, all of which, in their turn, raise
energy
consumption. We also construct opaque
financial products, rickety electronic voting systems and contradictory
global warming scenarios. Mechanical calculators may be an inferior
technology, but they had the benefit of keeping things on this planet
relatively simple. A brief overview of the most remarkable models.
