Electric Vehicles and the Electrical Grid: Can the Relationship Work?

(DGIwire) – Electric vehicles (EVs) feature strongly in a multitude of rosy visions about the future. Unfortunately, these visions don’t go as far at the moment as some might hope, thanks to a sobering realization: today’s electrical grid would likely fail catastrophically if the entire U.S. car fleet immediately made the switch to running on […]

Electric Bikes Pedal Toward Future With Carbon-Ion Batteries

(DGIwire) – Most of today’s electric bicycles are powered by lithium-ion batteries. But that technology has its drawbacks. As reported in Electric Bike Action magazine, when some bikes were switched from lead-acid to Li-ion in the early 2000s, the batteries could catch fire, and a few people burned their garages to the ground when charging […]

Japan Races to Embrace an Electric-Car Future

(DGIwire) – What is the biggest threat to traditional car manufacturers in Japan? As The New York Times recently reported, it is the advent of battery-powered electric vehicles.
