Mechanical calculators: computing without electricity
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.
