US researchers have developed a fully transparent solar panel, meaning that windows of the future can turn the sun’s energy into electricity. It consists of organic salts that absorb ultraviolet and infrared light, which then glow at another wavelength. Eventually, infrared light is guided to the edge of plastic, where thin strips of conventional photovoltaic solar cell convert it into electricity.
FOOD APPLIANCE – Kitchens will have appliances such as the Food Cycler, a countertop composter that turns food scraps into odourless compost in three hours. At present, less than 5 per cent of the more than 30 million tonnes of organic waste that enters landfill each year gets recycled. Food waste produces methane gas.
