An Ultrasonic Clothes Dryer Vibrates Clothes Dry


Researchers at Oak Ridge National Laboratory in Tennessee are trying to revolutionize the way Americans dry their clothes. They’re working on an ultrasonic dryer that vibrates moisture out, instead of evaporating it with heat, making the dryer more efficient and safer to operate. 

Working with GE, they're developing a prototype that swaps heat for ultrasound vibrations, using five to 10 times less energy than traditional dryers. See it in action in the video below. The vibrating dryer turns the moisture in wet clothes into a cold mist, and eliminates the danger of your clothes shrinking in a hot dryer. 

The first electric dryer was released in 1938 and became a popular fixture in American households after World War II. Now, some 85 percent of U.S. households have dryers and spend $9 billion a year to operate them [PDF], according to the Natural Resources Defense Council. By heating clothes in a rotating barrel, tumble dryers are exceedingly inefficient, using two to four times more energy than a new washer (and twice as much as European-style heat-pump dryers), and account for almost 6 percent of residential energy consumption [PDF]. These numbers are especially bleak considering there's a completely free, energy-efficient way to dry clothes: on a clothesline. 

For now, the ultrasonic dryer prototype is small and can only dry scraps of fabric, but the researchers estimate that a full-sized dryer could reduce drying times for a load by 15 to 20 minutes. Because of the lack of heat, the dryer also produces less lint, which can be a fire hazard when the lint trap isn't properly cleaned. 

The researchers expect to have a full working prototype by summer 2016.

A Visual History of Captain America’s Shields

Captain America has gone through plenty of wardrobe changes since his comic book debut in 1941, but it’s his iconic shield that has had the most makeovers. Over the past eight decades, fans have seen the shield change its shape, color, and even the material from which it’s crafted. For the folks at Pop Chart Lab, the shield’s storied history provided the perfect subject matter for their latest poster.

On this piece, the company teamed with Marvel to give a rundown of 50 of Cap’s shields—from the instantly recognizable to the downright obscure. Here we see his classic Golden Age shield, with its slightly different color scheme, and the different variations from Jack Kirby’s time-traveling Bicentennial Battles book. Then there are entries like the vibranium shield he received from Black Panther in Captain America #342 and an adamantium one made by Tony Stark.

Those different shields just scratch the surface of the deep cuts Pop Chart Lab provides. There are also shields from Captain Americas across Marvel’s numerous alternate universes, like the ones used by the Ultimate Universe Steve Rogers and the android Cap from Earth-725.

Each shield is illustrated to match its comic book counterpart and comes with a description specifying the series it debuted in and which Earth it exists on (the Marvel Universe has thousands of different versions of Earth, after all).

The posters will begin shipping on May 23, and you can pre-order yours now starting at $29 on the Pop Chart Lab website. You can check out a full look at the poster below.

Google Fixes Major Problem in its Cheeseburger and Beer Emojis

A digital slice of cheese that once sat beneath a digital beef patty has now ascended to its proper place in the hamburger emoji hierarchy. Google CEO Sundar Pichai saw to it personally.

"Towards the end of last year it came to my attention that we had a major bug in one of our core products," Pichai said in a keynote speech that opened this year's Google I/O conference for developers. After a pause, he added, "It turns out we got the cheese wrong in our burger emoji." Before and after images of the emoji were shown to an audience of more than 7000 people, bringing a satisfying resolution to an issue that was raised via tweet last October.

Author Thomas Baekdal was the first person to bring this crime against condiments to the public's attention, according to Dezeen. He tweeted, "I think we need to have a discussion about how Google's burger emoji is placing the cheese underneath the burger, while Apple puts it on top."

Pichai responded via tweet that he would "drop everything else" to fix it, and indeed, he kept his word. Google emojis are just one variety in the emoji universe, and they can be found on Android devices, Gmail, Google Hangouts, and ChromeOS.

Google's emoji experts were also tasked with fixing an image of a half-full mug of beer which had an inexplicable gap between the beer and the cloud of foam on top.

"We restored the natural laws of physics, so all is well, we can get back to business," Pichai said. Finally, a proper emoji meal can be had.
