Scientists in Canada have demonstrated a promising new device that can purify a gallon of water a day, for just a few cents per gallon. Better yet, it’s made of old tires, and can even generate small amounts of electricity.Continue ReadingCategory: Env… Continue reading Solar still made of old tires purifies 15 cups of water per day
As the days shorten and temperatures drop, it’s natural that people are likely to spend more time indoors even on sunny days. But new research has shown that by monitoring time spent in sunshine, which is also often linked to more physical activity, ca… Continue reading Beat the ‘winter blues’ by tracking your time in the Sun

Thanks to a recent discovery regarding marine algae, scientists have developed crop plants that absorb a fuller spectrum of sunlight, resulting in better growth. The finding could also lead to increased production of biofuels.Continue ReadingCategory: … Continue reading Algae-gene-boosted crop plants grow better by using more light
Scientists in Hong Kong have demonstrated a new ultra-white ceramic material that can drastically cool buildings by reflecting sunlight and heat at record highs. The beetle-inspired material gets its ability from its nanostructure, stays tough to the e… Continue reading Ultra-white ceramic cools buildings with record-high 99.6% reflectivity
Scientists have discovered that the Sun produces higher energy light than was thought possible. An unusual type of telescope detected gamma rays with energies of over 1 tera electron volt (TeV), at least five times more energetic than previously known…. Continue reading Gamma ray detection marks highest energy light from the Sun
If you leave a clear bottle of water in the sunlight, the ultraviolet rays will kill any harmful microbes in that water, making it drinkable … but it has to sit in the sun for at least six hours. A new sunlight-activated powder, however, does the job i… Continue reading Sunlight-activated powder disinfects water in just 60 seconds
Solar stills provide a clever and simple means of purifying dirty or salty water, but they work at a rather slow rate. A new material has been shown to boost their performance, and it’s made from fruit waste which would otherwise be discarded.Continue … Continue reading Simple process converts fruit waste into water-purifying material
There are already “smart” windows that can be electronically switched between either letting sunlight through or blocking it. A new multi-layered one, however, can be set to several energy-saving light filtration modes.Continue ReadingCategory: Energy,… Continue reading Multi-layer “liquid window” tech could help buildings save energy
We’ve already seen systems that wirelessly transmit data via patterns of flickering light. A Saudi Arabian team has created a less energy-intensive alternative, that could use modulated sunlight in place of traditional Wi-Fi.Continue ReadingCategory: S… Continue reading “Smart glass” windows could alter sunlight to replace Wi-Fi
