Energy-saving light-control film automatically controls sunlight transmission

This light-control film is based on the fact that there is a change in the incident angle of sunlight between summer and winter. The film blocks sunlight in summer by using total reflection but transmits it in winter. Unlike other light-control films, the film can control the transmission of direct sunlight while always allowing people inside to see the view outside the window.

Clean, green high performance biofuels from carbon dioxide

Could there come a time in which the carbon dioxide emitted from natural gas or coal-burning power plants that warms the atmosphere and exacerbates global climate change is harvested and used to produce clean, green and renewable liquid transportation fuels? A pathway to that possibility has been opened by a team of researchers who have engineered a microbe now being used to produce biodegradable plastic into a strain that can produce a high-performance advanced biofuel.
