A University of Colorado Boulder team has developed a new solar-thermal water-splitting (STWS) system for the efficient production of hydrogen. STWS cycles have long been recognized as a desirable means of generating hydrogen gas (H 2 ) from water and sunlight, the team notes. A paper on their work is published in the journal Science.
Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy.
Ford Motor Company is furthering its commitment to aggressively step up water conservation programs at its global facilities and among the company’s suppliers, according to its 15 annual Sustainability Report, released today. Plans are under way to further cut water use by another 2% this year and to set new long-term goals.
is well known that some higher plants can synthesize ammonia or its derivatives directly from air and water at room temperature. To the best of our knowledge, there is no report on artificial synthesis of ammonia direct from air and water. The ammonia produced by plants is normally directly used as fertilizer by the plants.
The ultra-small particles react with water to generate hydrogen 1,000 times faster than bulk silicon, 100 times faster than previously reported Si structures, and 6 times faster than competing metal formulations. Water can also be split chemically using a substance that can be oxidized by water, such as aluminum or silicon, the authors notes.

A new satellite study finds more than 75% of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought. This is a lot of water to lose. Credit: U.S.
With the small circuit, the water warms up very quickly. Once the engine is warm, the cylinder head management opens the next circuit and draws the water through the crankcase. Speed is variable; if the engine is idling, for example, there is reduced need to draw away heat, and thus no need for higher speed water flow.
