You may want to check the amount of available storage space on your e-reader, because classic books by Lewis Carroll, Agatha Christie, Aldous Huxley, D.H. Lawrence, and Virginia Woolf are now in the public domain. As Motherboard reports, the copyright on tens of thousands of books from 1923 expired on January 1, which means that these titles are now in the public domain and can be legally downloaded for free.

Because the copyright on works published between 1923 and 1977 is good for 95 years, this marks the first time in decades that a large number of books, movies, and songs has entered the public domain. Next year, items from 1924 will be available for download, and so on.

The list of titles up for grabs includes Jacob’s Room by Virginia Woolf, The Murder on the Links by Agatha Christie, The Prophet by Kahlil Gibran, The World Crisis by Winston Churchill, Don Quixote by Miguel de Cervantes, Alice’s Adventures in Wonderland by Lewis Carroll, The Three Musketeers by Alexandre Dumas, and many more.

Duke’s Center for the Study of the Public Domain has painstakingly listed nearly all of the new public domain works in an Excel spreadsheet, and a condensed list of the top titles is also available on its website. Unfortunately, you can’t get them all in one place, but a few reliable sources probably have what you’re looking for.

Project Gutenberg, HathiTrust, and the Internet Archive are a few of the digital libraries that let you download or read books online for free. You can also check the selections available on Read Print and The Literature Network. If those options fail, try searching for a specific title on Google Books.

A few noteworthy movies also recently entered the public domain. Some of them include Cecil B. DeMille’s The Ten Commandments and Charlie Chaplin's The Pilgrim. This essentially means these films can now be shown in theaters or public screenings without fear of violating copyright laws. Some of them are also available for viewing or download on the Internet Moving Image Archive.

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.
