Tackling urban water shortages: new technologies for self-sufficiency
04/09/2011
A Danish study of alternative water supply systems suggests that adopting a mix of different technologies could optimise the potential for water self- sufficiency in urban areas. Population growth and urbanisation are challenging current water supply systems. In many urban areas, attention has...
Danish LED greenhouse system lights path to energy savings
28/04/2009
A LED system producing photosynthetic wavelengths of light could result in dramatic energy savings for plant growers. The concept was developed in the University of Southern Denmark. Designed for use in greenhouses, the LED system emits light at the specific photosynthetic wavelengths that...
Nano-flake structure boosts solar cell performance
