France Will Build More Than 600 Miles of Solar-Powered Roadways

Original image

France may soon be the world’s leader in solar-powered roadways. Ségolène Royal, the country’s minister of ecology, announced a plan last month to pave more than 600 miles of French roads with photovoltaic panels, beginning this spring. The project will be completed over the next five years.

Made by Colas, a construction company that has been working on the technology for five years, the photovoltaic tiles are designed to stay warm enough to prevent ice from forming on top of them, and to withstand the weight of cars. According to the French plan, 1 kilometer of solar road (.6 miles) could power a town of 5000 people for a year. Should it work, the solar road network would provide 8 percent of the country’s population with electricity.

Some critics argue that solar roads will be too expensive to be worthwhile on a large scale, so France’s project will provide a more definitive test of the technology’s capabilities (or drawbacks). The photovoltaic cells will have to hold up under the impact of heavy traffic (including trucks) and remain safe in winter conditions.

France is not the first country to invest in solar roads, but it would be the first to do so for vehicular highways. A U.S. solar road project—funded by the U.S. Department of Transportation and more than $2 million raised on Indiegogo—is currently in the research phase, but has not begun a pilot test yet. South Korea and the Netherlands, on the other hand, are both experimenting with solar panels installed on bike lanes. Korea’s are installed on a structure on top of the bike lane, shading the cyclists below, while the Dutch solar panels are buried within the bike path itself. In 2015, the 328-foot-long Dutch pilot was able to generate enough power to run three homes for a year.

Tokyo Tops List of Safest Cities in the World, New Report Says

When choosing a city to call home, some might weigh factors like affordability, potential for job growth, and even the number of bookstores and libraries. But for many aspiring urbanites, safety is a top concern. This list of the world’s safest cities from the Economist Intelligence Unit (EIU) proves you don’t need to trade your sense of welfare for the hustle and bustle of city life—especially if you're headed to Tokyo.

As Quartz reports, the EIU assessed the overall safety of 60 major cities using categories like health safety, infrastructure safety, personal safety, and the cybersecurity of smart city technology. With an overall score in 89.80 out of 100 points, Tokyo is the 2017 Safe Cities Index's highest-ranking city for the third year in a row.

While it was rated in the top five places for cybersecurity, health security, and personal security, Tokyo's No. 12 spot in the infrastructure security category kept it from receiving an even higher score. The next two spots on the EIU list also belong to East Asian cities, with Singapore snagging second place with a score of 89.64 and Osaka coming in third with 88.67. Toronto and Melbourne round out the top five. View more from the list below.

1. Tokyo
2. Singapore
3. Osaka
4. Toronto
5. Melbourne
6. Amsterdam
7. Sydney
8. Stockholm
9. Hong Kong
10. Zurich

You may have noticed that no U.S. cities broke into the top 10. The best-rated American metropolis is San Francisco, which came in 15th place with a score of 83.55. Meanwhile, New York, which used to hold the No. 10 slot, fell to No. 21 this year. The report blames the U.S.'s poor performance in part on America's aging infrastructure, which regularly receives failing grades from reports like these due to lack of maintenance and upgrades.

History
In 1909, a Door-to-Door Catnip Salesman Incited a Riot in New York

In 1909, New York City businessman G. Herman Gottlieb was looking for a way to make a quick buck. He found it in a wooded section of Northern Manhattan, where wild catnip grew. After harvesting two baskets full of the plant, Gottlieb headed downtown to Harlem, intending to sell the product to residents with pampered felines.

As the history blog The Hatching Cat recounts, what Gottlieb didn’t know was that the neighborhood was also home to plenty of feral cats with voracious appetites. As Gottlieb made his way around the neighborhood, a handful of stray cats seized upon some leaves that had fallen out of his basket and began writhing and rolling around on the ground. Soon, even more kitties joined in, and “jumped up at his baskets, rubbed themselves against his legs, mewing, purring, and saying complimentary things about him,” according to an August 19, 1909 article in the St. Louis Post-Dispatch.

Gottlieb tried to frighten the cats away, according to The Washington Times’s account of the event, but the persistent animals wouldn’t budge. “All of them, rich and poor, aristocrats from the sofa cushions near the front windows and thin plebians from the areaways struggled mightily to get into the two baskets of catnip,” the Times wrote. Soon, Gottlieb found himself surrounded by somewhere between 30 and 40 cats, each one of them clamoring for his goods.

When he eventually spotted a policeman, Gottlieb thought he’d found an ally against the cats. Instead, Sergeant John F. Higgins promptly arrested Gottlieb for inciting a crowd. (“Why don’t you arrest the catnip?” Gottlieb asked him, according to the Times. “That is collecting the crowd. Not I.”)

Trailed by several cats, Higgins and Gottlieb made their way to a police station on East 104th Street. But when they arrived, authorities couldn’t decide whether or not the salesman had actually broken any laws.

“We can’t hold this man,” Lieutenant Lasky, the officer who received the arrest report, said. “The law says a man must not cause a crowd of people to collect. The law doesn’t say anything about cats.”

“The law doesn’t say anything about people,” Higgins replied. “It says ‘a crowd.’ A crowd of cats is certainly a crowd.” Amid this debate, a station cat named Pete began fighting with the invading felines, and, with the help of some policemen, eventually drove the catnip-hungry kitties out of the building.

Gottlieb was eventually released, and even driven home in a patrol wagon—all while being chased by a few lingering cats, still hot on the trail of his now regrettable merchandise.
