Wave-particle interactions in the solar wind and solar flares
… plasma waves play an important role in both the solar wind and solar flares. The dynamics of plasma turbulence in these settings controls the strength of the interactions, by determining the amplitudes of the small-scale electromagnetic fluctuations that have the largest effect on the particles. …

Developing a solar resource map for a stored solar cooker
Stored solar cookers collect energy using existing parabolic solar cookers and store the heat in a vessel filled with a salt. This stored solar cooker enables users to cook even when there is no radiation from the sun. The ability of the stored solar cooker to collect heat depends on the ambient …

Developing Solar War
Five years ago, I started development on Solar War, with the intent that I would someday publish it. During that time, I worked tirelessly to add features that would make this game unique and stand out. There were also setbacks during my journey, and times when I had to set the game’s development …

Luminescent solar concentrator structures for solar energy harvesting and radiation control
Luminescent solar concentrators are devices capable of converting some spectral components of solar radiation by luminescence and concentrating them before collection by photovoltaic. The aim of this thesis is to design, develop and demonstrate the principle of all-inorganic semitransparent …

Solar desiccant evaporative cooling with multivalent use of solar thermal heat
Solar DEC (Desiccant and Evaporative Cooling) air-conditioning is a renewable technological approach to the future air-conditioning of buildings driven with solar-thermal heat. The principal acceptance of solar airconditioning has led to system prototypes mainly across Europe, however the diffusion …

Series interconnected solar cells and solar cells with integrated bypass diode
A solar cell has a photovoltaic output voltage of about 0.5 volt and an output current proportional to cell area. Most present solar cell modules consists of small area cells connected in series to give desired output voltages. As large area substrates become available, e.g. continuously grown …

Beyond the solar surface: an observational study of solar coronal loops
… an observational analysis of structures in the solar corona. The plasmafl in the corona is low (<I), therefore, the emitting material is intimately linked to the magnetic fleldlines. The initial aim of this work, outlined in Chapter 3, is to take advantage of this relationship to calculate …

Solar thermal collector system modeling and testing for novel solar cooker
Solar cookers are aimed at reducing pollution and desertification in the developing world. However, they are often disregarded as they do not give users the ability to cook after daylight hours. The Wilson solar cooker is a solar cooker designed to address this problem by converting solar energy …

Enhanced Passive Solar Design: Studies in Solar Design and Human Health
Passive solar strategies have been present in architectural design for a long time. Basic concepts such as south facing openings to capture winter sunlight had been understood since ancient times and came about as a necessity to heat and cool a building with modern day mechanical systems. Over …

Comparison and Investigation of Solar Spectral Irradiance with Solar Aspect Monitor
… thermosphere is derived. The uniquely stable solar activity during 2010 allows the local time variation of NO to be observed with limited influence of solar variability. The comparison with a 1D model shows good agreement at altitude above 120 km, suggesting that most of the local time …
