Luís Euxebio Irías Calderón is the operator of a small hydroelectric power plant in the mountainous coffee country of northern Nicaragua, and he’s singing a song he wrote about turbines and transformers, to celebrate the arrival of electricity here in his remote corner of the country.
Carmakers are falling over themselves to announce full-electric, hybrid, and alternative-fuel vehicles at this year’s Detroit auto show. Chevrolet announced a concept for a mid-range fully electric car, the 200-mile-range Bolt, that might cost around $37,500 before tax credits in its 2017 lineup. The Bolt, designed by an Australian subsidiary of GM, will use a battery under development by LG that has a less block-like design than conventional battery packs and could offer carmakers more design flexibility.
The only current widely distributed electric car in that price range, the 84-mile range Nissan Leaf, will see “a lot of enhancements,” in time to compete with the Bolt, says Nissan-Renault CEO Carlos Ghosn.

Inside, the tube is attached to a machine that’s gobbling plastic flakes—which can come from used drink bottles—through a funnel also made from a plastic drink bottle. At the other end of the machine, a spinning wheel draws out the fresh-melted polymer into a black filament just three millimeters wide and value hundreds of times what it was worth in in bottle form.
