Why Rising Sea Levels Are a Problem for the Internet

If you get irrationally angry whenever your internet service provider allows a temporary drop in connectivity, you should probably develop some better coping skills. In the not-too-distant future, millions of users may be experiencing longer outages, thanks to rising sea levels.

In research prepared by the University of Wisconsin and recently presented at an academic conference in Montreal, scientists warned that climate change may soon have a radical impact on the way we’re able to obtain internet access, as Popular Science reports. Fiber-optic cables that allow for the transfer of data are buried underground and adjacent to coastlines—where sea levels are likely to rise in the coming years, saturating the cables and causing damage.

While some cables are run underwater and are housed in sheaths to prevent water from entering, cables buried underground were not intended to experience prolonged submersion. These affected cables—which measure more than 4000 miles in total length—will most likely become inoperable due to their exposure to damaging saltwater, corroding and losing the ability to transmit signals. The points where underwater cables connect to surface lines will also be vulnerable. Miami, New York, and Seattle are among the areas where connectivity could be most impacted.

Paul Barford, Ph.D., a computer scientist and the lead author on the paper, told Popular Science that this service interruption is likely to become a growing problem within the next 15 years. He cautioned that communications companies should begin implementing protective measures and solutions soon if they want to avoid major interruptions in the near future.

Charge Your Gadgets Anywhere With This Pocket-Sized Folding Solar Panel

Portable power banks are great for charging your phone when you’re out and about all day, but even they need to be charged via an electrical outlet. There's only so much a power bank can do when you’re out hiking the Appalachian Trail or roughing it in the woods during a camping trip.

Enter the SolarCru—a lightweight, foldable solar panel now available on Kickstarter. It charges your phone and other electronic devices just by soaking up the sunshine. Strap it to your backpack or drape it over your tent to let the solar panel’s external battery charge during the day. Then, right before you go to bed, you can plug your electronic device into the panel's USB port to let it charge overnight.

It's capable of charging a tablet, GPS, speaker, headphones, camera, or other small wattage devices. “A built-in intelligent chip identifies each device plugged in and automatically adjusts the energy output to provide the right amount of power,” according to the SolarCru Kickstarter page.

A single panel is good “for small charging tasks,” according to the product page, but you can connect up to three panels together to nearly triple the electrical output. It takes roughly three hours and 45 minutes to charge a phone using a single panel, for instance, or about one hour if you’re using three panels at once. The amount of daylight time it takes to harvest enough energy for charging will depend on weather conditions, but it will still work on cloudy days, albeit more slowly.

The foldable panel weighs less than a pound and rolls up into a compact case that it can easily be tucked away in your backpack or jacket pocket. It’s also made from a scratch- and water-resistant material, so if you get rained out while camping, it won't destroy your only source of power.

You can pre-order a single SolarCru panel on Kickstarter for $34 (less than some power banks), or a pack of five for $145. Orders are scheduled to be delivered in March.

Watch Ford's Sweaty-Butt Robot Put a Car Seat to the Test

Buyers tend to look at price, safety, and gas mileage when shopping for a car; a question that rarely comes up at the dealership is how well a car seat stands up to years of butt sweat. But even if it isn't a priority for car owners, the vehicle testers at Ford work to ensure the cars that leave the factory can accommodate the sweatiest passengers.

The secret to Ford's durable seats is a device called the Robutt. This video from the car company shows a Kuka robotic arm pushing a buttocks-shaped cushion into a car seat. To replicate a person sitting in the car after exercising, the dummy butt is heated to approximately human body temperate and pumped with half a liter of water. The average person produces about 0.7 to 1.5 liters of sweat in one hour of intense exercise, and people who are especially fit perspire 1.5 to 1.8 liters in the same time.

The sit test is repeated 7500 times over three days—simulating one decade of someone driving their sweaty behind home from the gym. If the surface of a car seat can make it through all that abuse without any wear and tear, the design is good enough for a Ford vehicle. Robutt-approved seats were first introduced in the 2018 Ford Fiesta and are now being built into all Ford vehicles in Europe.

You can watch the messy process play out below. Here are some more robots that, like the Robutt, were designed for oddly specific tasks.
