China is building the world’s first photovoltaic highway in Jinan The 2-km-long photovoltaic expressway is scheduled to open for public traffic by this year. This solar-powered highway consists of three layers: a…
Norway is testing auto-dimming streetlights
Most highways and streets are lit with streetlights at night to ensure safety on roads. But this needs lot of energy even when using more efficient LED bulbs. And, it creates light…
New desalination method offers low-energy alternative to purify salty water
Providing safer drinking water to those in need may be a little easier. According to Penn State researchers, a new desalination technique is able to remove salt from water using less energy…
Single metalens focuses all colors of the rainbow in one point
Metalenses — flat surfaces that use nanostructures to focus light — promise to revolutionize optics by replacing the bulky, curved lenses currently used in optical devices with a simple, flat surface. But,…
