Berkeley Lab engineers have developed a roof coating that can keep a building warmer or cooler, depending on the weather. When it’s warm out, the material will reflect sunlight and heat, but this radiative cooling automatically switches off in winter, … Continue reading Smart roof coating reflects heat in summer and traps it in winter
We wouldn’t go so far as to say “don’t try this at home”, but the way [Troy] brought an expensive (but out of warranty) laptop back to life is interesting, …read more Continue reading Laptop Gets Fixed by Simply Removing Problem Component
A thermal camera is a tool I have been wanting to add to my workbench for quite a while, so when I learned about the tCam-Mini, a wireless thermal camera …read more Continue reading Hands-On Review: tCam-Mini WiFi Thermal Imager
Sometimes a device doesn’t do quite what one needs, and in those cases a bit of tampering might do the trick. That’s what led to being able to record video …read more Continue reading Hacking a Thermal Imager for Dual-use of the Thermal Sensor
Australian researchers have created what may be one of the most thermally stable materials ever discovered. This new zero thermal expansion (ZTE) material made of scandium, aluminum, tungsten and oxygen did not change in volume at temperatures ranging … Continue reading Extraordinary new material shows zero heat expansion from 4 to 1,400 K
Let’s be honest — not too many of us have a need to deposit nanometer-thick films onto substrates in a controlled manner. But if you do find yourself in such …read more Continue reading Thin Coatings Require an Impressive Collection of Equipment and Know-How
The sun is a tremendous source of energy, and while photovoltaic panels are an easy way to harvest some of that energy especially now that prices for them are incredibly …read more Continue reading Heating A Home With Sunlight… And Water
We won’t pretend to fully grok everything going on with this open-source 8.5-digit voltmeter that [Marco Reps] built. After all, the design came from the wizards at CERN, the European Organization for Nuclear Research, home to the Large Hadron Collider …read more
Air conditioners and other cooling systems are among our biggest consumers of electricity, so finding ways to passively cool buildings will be important in our increasingly warmer future. Now, researchers at the University at Buffalo have developed a p… Continue reading Electricity-free radiative system cools buildings and heats water
When you buy a mass-market mobile phone, you’re making the decision to trust a long list of companies with your private data. While it’s difficult for any one consumer to fully audit even a single piece of consumer technology, there have been efforts to solve this problem to a degree. …read more
