Abstract:

The paper studied the effect of running and structural parameters on solar energy regenerator performance, in which pebble was storage material. Comparing simulated values to tested values of outlet air temperature, good agreement was achieved, which proved the model was correct. Taking average regenerative power as target function, the simulated results showed that the larger inlet air temperature, the larger average regenerative power. The smaller void fraction, the larger average regenerative power. The larger cross section velocity, the larger average regenerative power.

Abstract:

The rider of an E-bike has the option to rely solely on the motor, pedal while using the motor simultaneously, or pedal only, akin to a conventional bicycle. It's essential that the installation of photovoltaic (P.V.) panels on the electric bicycle does not compromise riding comfort. The idea behind solar energy integration is to equip the bicycle with a high-torque motor powered by solar energy absorbed through portable solar panels. This energy can directly power the motor if it meets requirements; otherwise, a battery serves as backup. During periods of inactivity, such as daytime, the sola

Abstract:

The Euler’s holomorphic regenerative universe is a quantum-gravitational theory of Earth development recognizing that oxygen, hydrogen, nitrogen and carbon dioxide in the Earth’s hydrosphere engender biological processes along with living organisms able to reshape the planet as surely as any physical force, but with delayed effects, the so-called torsional/gravitational buckling lag. Herein, the environmental sciences as a Vernadsky’s hypothesis precursor to these, become vital for preserving biological recurrent cycles, their nature being artificially changed by a vicious human intervention.

Abstract:

Solar energy is important for the future as it provides a clean, renewable source of electricity that can help combat climate change by reducing reliance on fossil fuels via implementing various solar-based energy systems. In this study, a unique configuration for a parabolic-trough-based solar system is presented that allows energy storage for periods of time with insufficient solar radiation. This model, based on extensive analysis in MATLAB utilizing real-time weather data, demonstrates promising results with strong practical applicability.

The study aims to introduce a novel system that powers a passenger train using supercapacitor energy storage that is charged by a solar carport system located at each train stop station. The system’s detailed design and its techno-economic analysis have been carried out and applied to a case study of a supercapacitor-based train (SC-Train) that connects an international airport with five major cities in the eastern region of Saudi Arabia. The objective is to reduce CO2 emissions from Saudi Arabia’s transportation sector utilizing an electric-operated train energized by a solar carport system.
