London Unveils New Electric-Powered Black Cabs

Black taxi cabs (or Hackney carriages, as they're often called) have been a fixture on London's streets for decades. A redesign from the London Taxi Company should ensure they stay that way well into the future. As The Guardian reports, the newly unveiled model of the city's black cab runs on gasoline and electric batteries.

The cabs most Londoners are used to hailing are currently powered by diesel fuel, which releases much more toxic emissions than regular gas. With London facing deadly air pollution levels, city officials are pushing to replace the smog-producers with cleaner modes of transport.

The new cab runs on an electric battery for the first 70 miles of its journey before switching to a fuel reserve for the next 400. (The average cab travels about 120 miles a day.) The London Taxi Company, which will soon rebrand as the London Electric Vehicle Company, plans to have as many as 150 cabs on the road by next year, with the first vehicles debuting in November.

Starting January 1, 2018, Transport for London will require all new taxis in London to be electric or have zero-emissions capabilities. Diesel cabs introduced before the cut-off will be allowed to stay, but after turning 15 they will need to be retired—therefore, the city should be completely diesel-free by 2032.

The black cab isn't the first four-wheeled London icon to receive an earth-friendly update. In 2016, Transport for London launched its inaugural fleet of all-electric double-decker buses, vehicles the agency claimed were the first of their kind.

A Free Cup Share Program Is Coming to Coffee Shops in Boulder, Colorado

Paper coffee cups are wasteful, taking decades to break down in a landfill after they're used for just a small part of someone's morning. But they're also irresistibly convenient to many. A new startup called Vessel Works is aiming to tackle the waste problem at coffee shops by applying the convenience of disposable to-go cups to reusable mugs, Fast Company reports.

The program, which is launching in four Boulder, Colorado cafes, takes the pressure off of customers to provide their own reusable cups. Instead, they can download an app and use it to check out an insulated, stainless steel mug free of charge. Throughout the day, the app updates them on ways their choice has made a difference, including how much waste they've prevented, how much water they've conserved, and how much they've reduced their carbon footprint. When they're done with the drink, users have five days to return their mug to a Vessel kiosk; from there it will be cleaned in one of the startup's facilities and returned to a cafe where the cycle will start all over again.

Vessel isn't the first company to attempt to bring reusable cups into the sharing economy. In 2016, coffee shops in Hamburg, Germany adopted a program where customers could acquire a mug for a small deposit and return it to a participating cafe to get their money back. Vessel Works's program differs in that users are never asked to pay unless they fail to return their cups on time (in that case, they'll be charged a fee).

Vessel is currently working with Boxcar Coffee Roasters and Trident Booksellers and Cafe in Boulder, and is coming soon to Seeds Library Cafe at the Boulder Public Library and the Pekoe Sip House at the University of Colorado. The startup hopes to eventually expand to more cafes and install dropoff kiosks at more convenient locations like transit stops.

This Live Stream Lets You Eavesdrop on Endangered Killer Whales' Conversations

Southern resident killer whales, which are usually found off the coasts of Washington, Oregon, and British Columbia, are an endangered species. If you're lucky, though, you might be able to hear a pod of the killer whales chattering away from the comfort of your own home. A website spotted by The Kansas City Star lets you live stream the calls of killer whales from your phone or laptop. Dubbed Orcasound, it uses hydrophones (underwater microphones) to pick up oceanic sounds from two areas off the coast of Washington.

On the website, listeners can choose between the two locations. One is the Orcasound Lab in Haro Strait, which is situated off the coast of Washington's San Juan Islands—the "summertime habitat" of this specific ecotype of whale, according to the website. The other location is Bush Point at the entrance to Puget Sound, where the whales pass through about once a month in search of salmon. However, that hydrophone is currently being repaired.

So what do orcas sound like? They're loud, and they do a whole lot of whistling, whining, and clicking. You can hear a snippet of what that sounds like in a four-minute podcast uploaded to the Orcasound site.

There’s no guarantee you’ll hear an orca, though. "Mostly you'll hear ships," the website notes, but there's also a chance you'll hear humpbacks in the fall and male harbor seals in the summer.

The live stream isn't just for educational purposes. It also serves as a citizen science project to help researchers continue their studies of southern resident killer whales, which are in danger of starvation as Chinook salmon, their main food source, die off.

The makers of Orcasound are urging listeners to email ihearsomething@orcasound.net anytime they hear killer whales or "other interesting sounds." They can also log their observations in a shared Google spreadsheet. Eventually, developers of the site hope to roll out a button that listeners can click when they hear a whale, to make the process easier for people to get involved.
