As we experience temperature extremes more often as a result of climate change, it predictably leads to an uptick in the use of air conditioning systems. This of course results in higher energy use, which, if it’s not coming from renewable sources, mea… Continue reading Spaceship tech slashes energy usage of existing AC systems by 50%
It’s an unfortunate irony that while many regions struggle to find enough water, there’s trillions of liters of the stuff floating around in the air everywhere. A new water harvester design from MIT can pull enough fresh water out of the air to meet th… Continue reading Harvester pulls 1.5 gallons of drinking water from arid air per day
Most 3D printer filament soaks up water from the air, and when it does, the water passing through the extruder nozzle can expand, bubble, and pop, causing all kinds of …read more Continue reading Instant Filament Drying Satisfies an Immediate Need
For those new to fields like robotics or aerospace, it can seem at first glance that a problem like moving a robot arm or flying an RC airplane might be …read more Continue reading A General-Purpose PID Controller
Researchers have developed a product that reduces hair’s moisture-absorbing tendencies, maintaining frizz-free curls for at least six hours in high-humidity environments and even allowing them to bounce back thanks to its shape-memory properties.Contin… Continue reading Shape-memory hair product keeps curls curly even in 80% humidity
With the increase in popularity of Internet of Things (IoT) devices and their need to communicate wirelessly, there’s been a corresponding explosion of wireless protocols to chose from. Of course …read more Continue reading Converting Bluetooth Sensors to Zigbee
Heat pumps are taking the world by storm, and for good reason. Not only are they many times more efficient than electric heaters, but they can also be used to …read more Continue reading Heat Pump Control That Works
Online weather services are great for providing generic area forecasts, but they don’t provide hyperlocal data specific to your location. [Harald Kreuzer] needed both and built a Raspberry Pi Weather …read more Continue reading Raspberry Pi Weather Station Features Wireless Sensor Nodes
Australian researchers have developed and tested a way to electrolyze hydrogen straight out of the air, anywhere on Earth, without requiring any other fresh water source. The Direct Air Electrolyzer (DAE) absorbs and converts atmospheric moisture – eve… Continue reading World’s first direct air electrolyzer makes hydrogen from humidity
Half of the solar energy that bathes the Earth in warmth goes into a single process, according to some researchers: evaporating the water that covers some 71 percent of our fragile blue marble. Australian company Strategic Elements wants that energy ba… Continue reading Self-charging moisture battery promises sweat-powered wearables
