Abstract
Sunlight though not heat, has inherent potential for direct conversion to mechanical work, just as heat does. The Physics pitching the possibility of direct conversion of nearly the entire sunlight received by a system into mechanical work has been formulated in this work. The feasibility of the concept has also been pursued, as well as alignment of the idea to the 2017-2027 predicted technology tipping points. Key to the ultimate realization of this propose, which argues for greater espousal of renewable energy options that foster attainment of engines for direct conversion of solar energy to mechanical work, are highly reflective and perfect mirrors. Smart areas and their associated favorable ecological footprints and climate change moderation will be among the key indicators of espousal of this conception.
Highlights
In Kenya, there exists laudable focus on how to support integrated approaches to addressing climate change in ways that embrace existing energy obligations and synergies, while minimizing trade-offs between climate change mitigation, adaptation and development [1]
Multi-junction solar cells [29,30], as well as the bulk hetero-junction solar cells [31] are achieving efficiencies far beyond the Shockley-Queisser-established theoretical limit for single-junction cells [30], which affirms this viewpoint, demonstrating that more can be achieved from sunlight than is currently done. It is this line of thought that enthused consideration of pursuing the idea of conversion of solar energy directly into mechanical work
The smallness of ), which is a necessary condition for such a solar energy to mechanical work conversion system to be practicable, has been satisfied by the presented formalism
Summary
In Kenya, there exists laudable focus on how to support integrated approaches to addressing climate change in ways that embrace existing energy obligations and synergies, while minimizing trade-offs between climate change mitigation, adaptation and development [1]. It is an area that holds immense potential, yet has received diminutive research interest, either from theoretical or practical perspectives In this option, solar energy is converted to thermal energy that performs shaft work through heat engines; an idea that can find use in the envisaged driverless cars, 3D printing, and robots and services. Multi-junction solar cells [29,30], as well as the bulk hetero-junction solar cells [31] are achieving efficiencies far beyond the Shockley-Queisser-established theoretical limit for single-junction cells [30], which affirms this viewpoint, demonstrating that more can be achieved from sunlight than is currently done It is this line of thought that enthused consideration of pursuing the idea of conversion of solar energy directly into mechanical work. A number of aligned and initially monochromatic photons that are confined to move back and forth between two perfect reflecting mirrors; M1 and M2, placed a distance x apart, as presented in Figure 1, formed the starting point of this conception
