Example of material experimentation. Now it is up to experimentalists to produce these new materials and discover their physical properties. Previous studies have shown that Curtarolo's methods are highly accurate in generating recipes for new, stable compounds, but they don't provide much information about their behaviors.

Next month an Australian-led coalition is expected to unveil a project to build experimental water-­purification reactors in drought-plagued ­northeastern Australia.

It seems that in the last decade scientists have switched goals from producing efficient LEDs to producing "natural light" LEDs. However, whenever this was achieved, significant efficiency sacrifices were made to enable experimentation to work. Through use of a nano-crystaline coating, it seems that scientists at Bilkent University, Turkey have succeeded in creating an LED that "produces attractive white light while wasting next-to-no electricity". The definition of attractive is that for each watt of light produced, around 300 lumens are visible to the human eye. This compares with fluorescents which produce around 80 lumens per watt, according to the article. There is however a barrier to market. This is because the nano-crystalline coating is expensive and apparently difficult to produce.
