Improving solar hydrogen production

Using a simple solar cell and a photo anode made of a metal oxide, scientists have successfully stored nearly five percent of solar energy chemically in the form of hydrogen. This is a major feat as the design of the solar cell is much simpler than that of the high-efficiency triple-junction cells based on amorphous silicon or expensive III-V semiconductors that are traditionally used for this purpose.

A melting Arctic could cost us $60 trillion

Arctic sea ice is retreating, with projections suggesting that the summer months will be substantially ice-free within the next few years. Nations are waking up to the possibilities for shipping and resource exploration this brings. But for all the potential economic benefits they glimpse, none have taken on board the hidden costs of an Arctic thaw.

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.
