Spongey filter releases purified lake water when set in the sun

Ironically, many of the places that most require water purification have the least-developed infrastructure. That’s where a new filtration device comes in, as it’s activated by the sun – and it’s said to perform better than other solar-powered purifica… Continue reading Spongey filter releases purified lake water when set in the sun→

Sunlight-concentrating ball illuminates dark places

If you worked in a dingy, windowless environment, it would be nice (and energy-efficient) if you could get natural daylight “piped in” from outside. An experimental device does exactly that, in a new compact and robust form.Continue ReadingCategory: Go… Continue reading Sunlight-concentrating ball illuminates dark places→

“Artificial Sun” Lighting Via Old Satellite Dishes

Real sunlight is a beautiful thing, but due to the vagaries of Earth’s orbit and local weather systems, it’s not available all the time. [Matt] decided this wasn’t good enough, and set about building a rig to replicate the sun’s rays as closely as possible.

The great distance between the …read more

Super-white paint reflects 95.5 percent of sunlight to cool buildings

Researchers from Purdue University have developed a new white paint that can reflect over 95 percent of sunlight, which can cool the surface even lower than the ambient temperature. Painted on a building, the new paint could help cut cooling costs and … Continue reading Super-white paint reflects 95.5 percent of sunlight to cool buildings→

Skylight in any Room

Despite a glut of introvert memes, humans need sunlight. If vitamin D isn’t your concern, the sun is a powerful heater, and it helps plants grow. Sadly for [mime], their house is not positioned well to capture all those yummy sunbeams. Luckily for us, their entry into the 2020 Hackaday …read more

Ultraviolet LEDs proposed for skin-safe vitamin D production

Even though we’re warned about the harmful effects of the ultraviolet (UV) rays in sunlight, they’re essential for the production of vitamin D in the body. Now, scientists are claiming that UV LEDs could serve as a safe alternative to sunlight, when th… Continue reading Ultraviolet LEDs proposed for skin-safe vitamin D production→

Aerogel quickly and cheaply purifies water – by turning it to steam

By converting liquid salt water – or tainted water – into steam, it’s possible to obtain pure, clean drinking water. Doing so could soon be cheaper and easier than ever, thanks to a newly developed material.Continue ReadingCategory: Good Thinking, Life… Continue reading Aerogel quickly and cheaply purifies water – by turning it to steam→
