This California Gym Runs on Energy Generated by Your Workout

At Sacramento Eco Fitness in California, the energy clients expend is put to good use. As Inhabitat reports, the gym is outfitted with special ECO-POWR equipment from SportsArt that collects kinetic energy from users' workouts and feeds it into a battery used to power a portion of the gym's operations.

The fitness center features much of the same equipment you'd find in any gym, but its stationary bikes are more sophisticated than most. SportsArt's ECO-POWR cycles have built-in micro inverters—the same technology that solar panels and wind turbines use to convert natural energy into electricity—that harvest the watts generated when you pedal. The gym also recently debuted an ECO-POWR treadmill that can harvest energy generated during a run.

A single bike can generate as much as 200 watts per hour, and one spin class produces enough energy to power two fridges for 24 hours. The gym's battery can also be used to power lights and charge cellphones and laptops. The results are apparent in the gym's energy bill—after debuting the new equipment, its electricity costs dropped from $680 to $30 a month.

Eco Fitness isn't the only business tweaking the conventional gym model. The app POPiN, which rolled out in several health clubs in New York City in 2017, lets guests pay for gym time by the minute. People in New York can also check out FaceGym, the aptly named gym for working out your face.

Mapping Technology Reveals 'Lost Cities' on National Geographic

Imagine what Pompeii looked like before the lava hit, or Mayan pyramids before the jungle took over. In the past decade, scientists have been able to explore human settlements long since abandoned by using a new wave of accessible technology. Instead of needing an expensive plane and crew to fly aerial sensors, for example, explorers can mount them on cheaper drones and pilot them into previously unreachable areas. The resulting data can tell us more about the past, and the future, than ever before.

That’s the premise of Lost Cities with Albert Lin, a new TV series premiering on National Geographic on Sunday, October 20.

Lin, an engineer and National Geographic Explorer, uses cutting-edge tools to shed light on centuries-old cities in the most beautiful places on Earth. Ground-penetrating radar reveals buried structures without disturbing the landscape. A drone-mounted remote sensing method called LIDAR—short for "Light Detection and Ranging"—shoots lasers at objects to generate data, which Lin visualizes with 3D mapping software. The results suggest what the ruins probably looked like when they were new.

“It’s like a window into a world that we’ve never had before,” Lin tells Mental Floss. “It’s shooting millions of laser pulses per second through a distance of air. By digitally removing the top layer of everything above the ground—trees, brush, cacti—you’re washing away the past. All of the sudden you’re left with these fingerprints—experiments in how we organized ourselves through time.”

For the six-episode series, Lin and the expert storytelling team were dispatched to the South Pacific, the Middle East, the Andes, the Arctic, and other destinations. Lin explains that while most of the sites are known to archaeologists, they’ve never been so precisely mapped in three-dimensional detail.

In the first episode, Lin travels to Nan Madol, an enigmatic complex of temples and other structures on the Micronesian island of Pohnpei. With the help of local researchers and indigenous leaders, Lin and the team scan the ruins and digitally erase trees, water, and forest undergrowth to unveil the complex's former grandeur.

“Technology and innovation have always been that gateway to go beyond the threshold, and see what’s around the corner,” Lin says. “Seeing these worlds for the first time since they were left, it’s almost like reversing the burning of the library of Alexandria. We can take the synthesis of knowledge of all these watershed moments of our human journey, and imagine a better future.”

Lost Cities With Albert Lin premieres Sunday, October 20 at 10/9c and resumes on Monday, October 21 at 10/9c on National Geographic.

Samsung Is Fixing Bug That Lets Anyone Unlock Fingerprint-Protected Galaxy S10s

Users of the Samsung Galaxy S10, fear not: A fix is on the way for your device’s faulty fingerprint reader. According to Engadget, Samsung Electronics told Reuters in a statement that it is “aware of the case of the S10’s malfunctioning fingerprint recognition and will soon issue a software patch.”

Soon after the device’s initial release, consumers discovered that a 3D-printed fingerprint could unlock the phones. Then, UK user Lisa Neilson reported to The Sun that any human fingerprint would work on her phone. Though we don’t know exactly why the technology is malfunctioning, it has happened through the use of third-party plastic or silicon screen protectors—Neilson had purchased hers on eBay.

“It’s a real concern,” Neilson told The Sun, in large part because people nowadays store much more than contacts and photos on their smartphones. “Anyone can access it and could get into the financial apps and transfer funds.”

Samsung users can protect their phone's security with an old-fashioned number code. Though not as hassle-free as the fingerprint mechanism, the code will work just fine.

The company hasn’t disclosed when we can expect a solution, though it confirmed to Engadget that an internal investigation is underway and customers should stick to using authorized Samsung products in the meantime, rather than third-party screen protectors.
