Cheap and Safe Hydrogen Solution by Indian and Italian Researchers

Benji Jerew — Fri, 18 Jan 2013 16:13:58 +0000

Mention hydrogen, and for anyone who’s watched Myth Busters or The History Channel, the name Hindenburg immediately comes to mind. The reason is because hydrogen, especially large quantities of pure hydrogen, is one of the most reactive substances we know of, and it wants to get rid of that solo electron so bad it’ll bond […]

Concentrated Sunlight Generating Hydrogen from Water and Splitting Carbon Dioxide

Ovidiu Sandru — Mon, 27 Dec 2010 20:34:28 +0000

I've known for years that solar concentrators do a good job at harnessing heat. You may also use them to generate electricity, but it's not their best job possible. A recent article published in the journal Science shows how solar concentrators can be used to directly extract hydrogen from water, without any middlemen such as photovoltaic panels and electricity.

Unexpected Discovery Brings Three Times More Solar Power

Ovidiu Sandru — Mon, 27 Apr 2009 19:52:28 +0000

Sometimes, what we get is not what we expect - at all. For example, a team of scientists from Northeastern University and from NIST discovered by mistake how to produce more solar power by using the residue of a process used to build arrays of titania nanotubes. Now, physorg.com interprets this invention through the perspective of better hydrogen production, but improving the solar power capturing ability gives a lot more useful applications than only that of hydrogen production.
