Technology could lead to more reliable renewable energy systemsTue, 03 Dec 2013 12:45:45 EST
Renewable energy sources such as wind-powered generators can be more reliable and efficient by better controlling the process of getting electricity onto the power grid, according to new research. New light shed on solar water-splitting processMon, 02 Dec 2013 11:21:21 EST
Scientists have provided new insight into how solar water-splitting cells work. An important and overlooked parameter, they report, is the ion-permeability of electrocatalysts used in water-splitting devices. Copper promises cheaper, sturdier fuel cellsFri, 22 Nov 2013 10:39:39 EST
Chemists are exploring the use of copper nanowires in fuel cells to convert solar energy into storable fuel. Copper nanowire catalysts cost less to produce than their indium tin oxide counterparts because they can be "printed" on pieces of glass or plastic in a liquid ink form, using a machine that functions much like a printing press. The nanowires can also be incorporated into transparent, flexible films. Power boosting self-cleaning solar panelsThu, 21 Nov 2013 11:18:18 EST
High-power, self-cleaning solar panels might be coming soon to a roof near you. There are two obvious problems with photovoltaic cells, solar panels. First, they are very shiny and so a lot of the incident sunlight is simply reflected back into the sky rather than being converted into electricity. Secondly, they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Now, new research suggests that it might be possible to add a nanoscopic relief pattern to the surface of solar cells that makes them non-reflective significantly boosting efficiency and at the same time making them highly non-stick and self-cleaning. Solar-powered battery woven into fabric overcomes hurdle for 'wearable electronics'Wed, 20 Nov 2013 11:20:20 EST
Though some people already seem inseparable from their smartphones, even more convenient, wearable, solar-powered electronics could be on the way soon, woven into clothing fibers or incorporated into watchbands. This novel battery development could usher in a new era of "wearable electronics."
