Solving a condensation mystery

Posted by in categories: computing, engineering, sustainability

Condensation might ruin a wood coffee table or fog up glasses when entering a warm building on a winter day, but it’s not all inconveniences; the condensation and evaporation cycle has important applications.

Water can be harvested from “thin air,” or separated from salt in desalination plants by way of . Due to the fact condensing take heat with them when they evaporate, it’s also part of the cooling process in the industrial and high-powered computing arenas. Yet when researchers took a look at the newest method of condensation, they saw something strange: When a special type of is covered in a thin layer of oil, condensed water droplets seemed to be randomly flying across the surface at high velocities, merging with larger droplets, in patterns not caused by gravity.

“They’re so far apart, in terms of their own, relative dimensions”—the droplets have a diameter smaller than 50 micrometers—” and yet they’re getting pulled, and moving at really high velocities,” said Patricia Weisensee, assistant professor of mechanical engineering & materials science in the McKelvey School of Engineering at Washington University in St. Louis.

Farmed Salmon = Most Toxic Food in the World

Posted by in categories: biotech/medical, food, health, sustainability

Fish are an important part of the ecosystem and the human diet. Unfortunately, overfishing has depleted many fish stocks, and the proposed solution — fish farming — is creating far more problems than it solves. Not only are fish farms polluting the aquatic environment and spreading disease to wild fish, farmed fish are also an inferior food source, in part by providing fewer healthy nutrients; and in part by containing more toxins, which readily accumulate in fat.

Farmed Salmon = Most Toxic Food in the World

Salmon is perhaps the most prominent example of how fish farming has led us astray. Food testing reveals farmed salmon is one of the most toxic foods in the world, having more in common with junk food than health food. Studies highlighting the seriousness of the problem include:

What Could Possibly Be Cooler Than RoboBee? RoboBee X-Wing

Posted by in categories: robotics/AI, solar power, space, sustainability, transportation

They used to call it RoboBee—a flying machine half the size of a paperclip that could flap its pair of wings 120 times a second. It was always tethered to a power source, limiting its freedom. Now, though, RoboBee becomes RoboBee X-Wing, as Harvard researchers have added solar cells and an extra pair of wings, freeing the robot to blast off to a galaxy far, far away. Or at least partway across the room, as it can sustain flight for only half a second, and only indoors.

But hey, baby steps. The teeniest of quadrotors measure a few inches across and weigh a third of an ounce. RoboBee X-Wing is about the same size as those untethered fliers, but weighs a hundredth of an ounce, which earns it the distinction of being the lightest aerial vehicle to manage sustained untethered flight. One day that could make it ideal for navigating tight, sensitive spaces in a galaxy very, very near.

Baldness breakthrough uses 3D-printed “hair farms” to grow new hair follicles

Posted by in categories: 3D printing, food, sustainability

An exciting breakthrough from Columbia University researchers demonstrates a new way to grow human hair follicles using 3D printed molds. This is the first time human hair follicle cells have been grown completely in lab conditions, opening up a potentially unlimited source of hair follicles for future hair restoration surgical procedures.

New Tesla Pickup Truck Costs Just $49,000 And Will Topple The F-150s

Posted by in categories: Elon Musk, space, sustainability, transportation

Tesla and the electric cars they produce are renowned for their sleek design and high tech capabilities. There is currently a saloon car (Model S), a budget version (Model 3), an SUV (Model X) and of course, the famous Roadster model which was launched into space by Elon Musk himself. There’s also a mid-sized car which is planned to be released later this year — the model Y, which is in between an S and an X. So, what’s missing from this luxury vehicle line-up? A pickup truck, of course! Tesla’s got that covered as well!

The latest Tesla model that Elon Musk has revealed is an electric pickup truck. Currently, it’s just a rumor and there has been no leak of the design or any details about this truck. That said, there is no shortage of speculation and many people seem to have their own opinions on the appearance of the new Tesla truck. However, one thing that is known is Tesla’s are expensive. Not only the design but the interior and the technology they scream luxury and offer amazing comfort. They are arguably some of the best electric vehicles on the market today but costs can run upwards of $100,000 for the latest models.

So, as anyone would expect, the new pickup truck was predicted to cost in the region of high five-, maybe even low six-figures. However, the price range has been revealed and it’s shocked everyone — apart from the Model 3, this could be one of the cheapest Tesla cars ever produced.
