emerging technologies increase the needs on self efficient mobile robotic applications that bring a new concern of sustainable and continuous power supply for the robotic platforms. this paper covers the various techniques and technologies used to design a solar powered robot, exploring the currently available products, software and limitations to this application. the main aim is to integrate ...

The solar energy research community has realized the redundancy of image-forming while collecting/ concentrating solar energy with the discovery of the nonimaging type radiation collection mechanism in 1965. Since then, various nonimaging concentration mechanisms have proven their superior collection efficiency over their imaging counter-parts. The feasibility of using nonimaging concentrators ...

Anderson, et al. have recently reported the discovery of an apparent anomalous, weak, long-range acceleration in the Pioneer 10/11 and Ulysses spacecraft. I believe that this result can be explained by non-isotropic radiative cooling of the spacecraft electronics through passive radiators on the spacecraft surface. These radiators are preferentially placed on the anti-solar side of the spacecra...

in this paper by the introduction of the basic equipment of a solar cooling system, solar hydrogen ammonia refrigeration system as a solar cooling technique will be discussed. using heat collector and absorption refrigeration allows us to use residual heat, for cooling, heating and producing hot water and boiling water .this research focuses on methods of heat transfer from the sun into the gen...

This paper presents the performance evaluation of a passive solar dryer. The Dryer was designed and constructed at Mechanical Engineering Department Caritas University, Amorji-Nike, Enugu, Nigeria. using locally sourced materials from Ogbete main market, Enugu. Experimentation carried out samples 20mm 40mm sliced cassava chips weighing 46g 80g respectively in month November, 2020.Temperature re...

The main purpose of the passive remote sensing instruments GOME and SCIAMACHY is to determine the amount and distribution of a large number of atmospheric trace constituents by measuring Earthshine radiance. In addition solar observations are performed on a regular time grid which offer the possibility to monitor solar variations. This paper summarises the derivation of a proxy solar activity i...
