In the American Navy research laboratories it was developed a hydrogen fuel cell-powered plane that was capable to fly during more than 23 hours in a test accomplished last week. The Íon Tiger, as it is called, got to fly during that period without emitting any pollutant particle and its motor is silent, a secondary [...]

From the Hubble telescope’s images of planetary nebulae comes the idea of how the sun will eventually look when it expires five billion years hence. Once it has exhausted its reserves of hydrogen that feeds a continuous process of nuclear fusion, the sun will become just like any of the nebulae the most beautiful of [...]

Photosynthesis, the process which energizes plants by breakdown of water using sunlight got artificial. Nocera and his colleagues conducted an experiment in which solar panels were used to power an electrolyzer with cobalt and phosphate catalysts to break down water into its elemental constituents, hydrogen and oxygen. The hydrogen thus produced was fed into a [...]
