How Nissan is Using Old Batteries to Light a Town Hit By the Fukushima Disaster

In 2010, Nissan debuted the Leaf: an electric car with a battery range built to compete with cars that run on fossil fuels. Now, Nissan is testing ways to use the technology even after a vehicle has been taken off the road. As engadget reports, old Leaf batteries are being used to power streetlights in Japan.

Namie, Japan, which transformed into a ghost town following the 2011 Fukushima nuclear disaster, is the initial test site of the project, dubbed "The Reborn Light." There, streetlights have been outfitted with batteries from out-of-commission Leaf vehicles. During the day, sunlight hits a solar panel attached to the battery. Then, at night, the battery-powered lamps can illuminate the streets without any support from the main power grid.

As the technology improves, electric vehicles are becoming more mainstream, and car companies are looking for ways to get the most out of the materials used to make them. When lithium-ion batteries aren't sent to recycling plants, they can be repurposed into batteries that capture wind power outside people's homes, or batteries that harness the energy of playing children in a park—both ideas that Nissan is considering.

After launching a small-scale trial of the battery-powered lights in Namie, Nissan plans to install the lamps throughout the town later this year. As of now, the area is still uninhabitable, with the Japanese government hoping to lift evacuation orders for parts of it by 2023.

McBroken: This Website Saves You a Trip to McDonald's By Telling You If Their Ice Cream Machine Is Down

Fast food is about indulgence, and there are few menu items that promote cravings more than the soft-serve ice cream cones and McFlurry treats at McDonald’s. These pseudo-dairy desserts have an ardent fan base despite the fact that the machines dispensing them are frequently out of service for maintenance or cleaning.

Now, a new website can inform customers when a McDonald’s ice cream machine may be down. It’s called McBroken, and The Verge reports it was created by 24-year-old software engineer Rashiq Zahid. The site maintains a map that displays in real time which restaurants are able to offer ice cream and which aren't.

How does Zahid gather this information? A program attempts to place a McSundae order at every McDonald’s location in the United States via their app. If it’s added to his cart, the location gets a green dot and is prepared to dispense ice cream. If not, a red dot indicates there will be no ice cream forthcoming.

McBroken also keeps a running tally of the percentage of all restaurants without a working machine. At last glance, it was at 10.93 percent.

According to The Verge, Zahid was inspired to create McBroken after failing to retrieve a McSundae while in Berlin, Germany, over the summer. His program, or bot, originally attempted to order a McSundae every minute, but the McDonald’s app declared the activity suspicious. Now, he has set it to attempt an order every 30 minutes. The system works, Zahid said, because he verified the results against locations he visited in Berlin in person.
