In this paper we discuss optical considerations and present design simulation results for a self-tracking (passive) solar concentrator. The self-tracking mechanism uses a reversible in-plane paraffin thermal actuator to couple short-wavelength light into a ...
We present a proof of principle demonstration of a reversible in-plane actuator activated by focused sunlight, and describe a concept for its use as a self-tracking mechanism in a planar solar concentrator. By actuating at the location of focused sunlight ...
Amidst a backdrop of rapidly increasing world-wide electricity demand, solar thermal power generation shows great potential for supplying the electricity needs of numerous countries in the Sun-belt regions of the world. In these regions, the absence of sig ...
What will the cities of tomorrow look like? This is a crucial question because in the four and a half billion years of its existence, the Earth has never been so threatened, as it is today. Since 2008 half of the world's population has lived in towns – mor ...
We present to the best of our knowledge the first successful demonstration of a planar, self-tracking solar concentrator system capable of a 2-dimensional angular acceptance of over 40 degrees. The light responsive mechanism allows for efficient waveguide ...
Renewable and available in abundance, incident solar radiation is an ideal candidate for energy production. The development of nanostructured coatings for the improve- ment of technologies that convert solar energy into heat and electricity opens interesti ...
This article integrates solar potential in a given urban area for the competing technologies of Photovoltaic and thermal collectors. On an urban level, scalable from several buildings to whole cities, the authors examine the possibility of solar power inte ...
The International Energy Agency (IEA) Task 41 is conducting an international survey concerning the integration of solar energy systems and architecture in order to identify barriers that architects are facing in incorporating active solar technologies in t ...

In the framework of the EU-project SOLZINC, a 300-kW solar chemical pilot plant for the production of zinc by carbothermic reduction of ZnO was experimentally demonstrated in a beam-down solar tower concentrating facility of Cassegrain optical configuratio ...
