Magic of physics makes this fridge chill food without fans or electricity

Add as a preferred source on Google

Coolers are big business on Kickstarter, dating back to the multi-function Coolest Cooler, which racked up an epic $13 million in pledges several years ago. Now a new refrigeration system has landed on the popular crowdfunding platform — and it’s missing one big feature. What feature is that? Just a little thing we call the need for electricity!

As a result, the electricity-free, fan-free, air compressor-free Yuma 60L fridge — which runs solely on water — could be useful for both your upcoming camping trip and, potentially, in developing countries or disaster areas where power is in short supply. While it won’t keep your beers as frosty as a standard compression refrigerator, it does promise to retain a “nice and refreshing” temperature level for anything stored in it. And all without needing to be plugged in.

“The Fenik Yuma cooler is a portable food preserver that never needs ice or electricity,” co-founder Jeremy Fryer-Biggs told Digital Trends. “It comes totally flat, and pops up like a tent in under 20 seconds. This allows you to easily take it anywhere. Once assembled, you open the door, place your food inside and activate it by pouring water into the fill-port. The water absorbs heat energy from your food and evaporates through a smart material called PhaseTek, in much the same way that your body cools itself. The result is that your food lasts much longer. Yumas will work anywhere in the world where there isn’t excessive humidity and can be stacked to save space or collapsed again for easy transport.”

Fryer-Biggs said that the germ of the idea behind the project started when one of his co-founders, Quang Truong, was working with farmers in Liberia and Vietnam to improve the productivity of their crops. Witnessing food rotting in the fields and in open air markets, he set about looking for a way to solve a problem — lack of refrigeration — that affects around 1.2 billion people around the world. This adds up to nearly a trillion dollars in wasted productivity and 8 percent of global greenhouse gas emissions. Truong settled on evaporative cooling: based on the observation that when water evaporates, the surface it was on gets colder.

As ever, we offer our usual warnings about the risk inherent in crowdfunding campaigns. However, if you’re aware of these and still wish to get involved, head over to the Fenik Yuma cooler project page for more information. Prices for the cooler (plus handy carrying strap) start at $120. A $250 pledge, meanwhile, will secure a cooler for yourself and provide one to a family in need. Provided the project hits its funding target, shipping should take place in March 2019.

AI agents are sitting through students’ online courses, and colleges are struggling to stop them
The technology has moved from helping with homework to effectively impersonating students inside virtual classrooms.

AI cheating has already gone from asking a chatbot to write an essay to using tools that can make that AI-written work look human. We've previously talked about AI tools designed to help students cheat and the growing problem of AI detectors struggling to keep up, as well as how commonly students are already using AI for homework. Now the technology isn't merely helping students do the work. In some cases, it can effectively be the student.

Researchers built a tiny wearable patch that measures cholesterol levels from your sweat
Skipping the lab visit might actually be possible in the future.

Think about the last time you actually had your cholesterol checked. If you are like most people, it has probably been years since it usually means scheduling a lab visit and getting your blood drawn. Caltech researchers just built something that could change that entirely — a small stick-on patch that reads your cholesterol and triglyceride levels continuously, using sweat instead of blood.

Chinese startup claims its brain implant takes just 10 minutes to place, no skull surgery required
StairMed Technology's vein-based BCI could beat Neuralink's roughly two-hour surgery on speed, but the device still hasn't undergone human trials.

Brain implants, like the ones made by Elon Musk's Neuralink, typically involve open-skull surgery. But a Chinese startup says it can skip that step entirely, threading its device into the brain through a vein in a procedure that reportedly takes as little as ten minutes. According to the South China Morning Post, Shanghai-based StairMed Technology is one of several companies pursuing this approach, as the country pushes to expand its homegrown brain-computer interface (BCI) industry.
