Wireless device makes clean fuel from sunlight, CO2, water: Study

Researchers claim to have developed a wireless device that converts sunlight, carbon dioxide and water into carbon-neutral fuel. The device is based on advanced 'photosheet' technology and converts sunlight, carbon dioxide and water into oxygen and formic acid. It doesn't require components from solar cells and relies solely on photocatalysts embedded on a sheet to produce a 'photocatalyst sheet'.
