Cooking, a fundamental human necessity, frequently relies on environmentally harmful energy sources. Concentrated solar power offers a promising solution through solar cookers to address this issue. This study assesses a Parabolic Trough Collector (PTC) solar cooker's performance with two reflector materials: chrome stickers and glass mirrors. The PTC-type solar cooker comprises essential components, including an absorber tube, a flexible conduit, and a spiral-shaped cooking container holder that accommodates a diverse range of cooking vessels. In the configuration of the PTC collector, reflectors fabricated from chrome stickers and glass mirrors are strategically employed to harness and concentrate solar radiation effectively. The absorber tube, crafted from copper, is filled with a heat-transfer fluid consisting of soya oil. Experimental investigations were conducted in a two-stage process, encompassing trials without any applied load and subsequently with varying loads. In the no-load experiments, alterations were made to the PTC collector's inclination angle, spanning the ranges of 15º, 20º, 25º, and 30º. In contrast, the load-bearing tests encompassed the assessment of the PTC solar cooker's performance under a diverse array of cooking scenarios, including boiling water, heating oil, frying eggs, and crisping crackers. The evaluated parameters encompassed key metrics such as incident solar radiation (Ir), ambient temperature (Ta), receiver temperature (Tr), fluid temperature (Tf), spiral furnace temperature (Tsf), and load temperature (To). Subsequently, the outcomes of the experiments were employed to determine the efficiency of the solar cooker. Analysis of the no-load test results indicates that the most favorable performance, as observed in the parameters Tr, Tf, and Tsf, is achieved at a collector inclination angle of 15º for both chrome sticker and glass mirror reflector materials. The solar cooker demonstrated commendable proficiency in boiling water, heating oil, frying eggs, and crisping crackers, accomplishing these tasks within a time frame ranging from 5 to 20 minutes. Notably, the solar cooker featuring the glass mirror reflector exhibited a superior thermal efficiency of 33.7%, surpassing the efficiency of the counterpart with the chrome sticker reflector, which registered an efficiency of 30.9%. These findings underscore the efficacy of the glass mirror reflector in harnessing solar energy for enhanced cooking performance within this solar cooker configuration.

The heat pipe (HP) is a fundamental heat transfer component frequently utilized for energy recovery in heating, ventilation, and air conditioning (HVAC). However, a heat pipe transmits heat from the hot side (evaporator) to the cold side (condenser), resulting in a temperature difference on both sides. There are numerous methods for measuring heat pipe performance. Using the temperature difference between the evaporator and condenser, the performance characteristics may be evaluated. The objective of this study is to compare the thermal performance of thermosiphon and commercial wick heat pipes (WHP) utilizing water as the working fluid and varying temperatures between the evaporator and condenser. The copper thermosiphon and commercial wick heat pipe had a diameter of 10 mm, a length of 800 mm, and a vacuum pressure of 5000 Pa. The filling ratios range between 30% and 50%, and it was evacuated at a pressure of 5000 Pa; the hot water temperatures at the evaporator were 30, 50, 70, and 90 ºC. Temperature was steadily increased every 30 minutes, and variations were observed at multiple places, including hot water, evaporator, and condenser wall. The average difference in temperature between the WHP and thermosiphon was around 0.6 degrees Celsius. The decreased temperature difference (T) indicates that the heat pipe is performing well. In addition, if the temperature difference is very great, the HP will dry up, therefore the WHP performs better than the thermosiphon.

The demand for electricity is continually increasing. Typically, electrical energy is generated using fossil fuels such as coal in thermal power plants. Generally, these power plants or other electricity generators supply power to densely populated areas such as large cities. Remote areas, however, often lack access to electricity due to their distance from urban centers. One solution to this issue is the development of micro-hydropower plants (MHPs). In MHPs, turbines are generally made of metal, which has high inertia and thus leads to lower efficiency. Therefore, this study replaces the turbine in an MHP with one made of fiberglass to assess the material's resistance to the water pressure in MHP operations. Based on the research conducted, the allowable stress for the fiberglass was determined to be 11.59801 MPa, with the water pressure applied to be 0.000985 MPa.

The existing drying system struggles with efficiency and costs, contradicting its intended resource-saving purpose. Addressing these issues could generate increased interest in its utilization. To tackle this, precise control of the dryer's temperature and optimization of the heat source are essential for obtaining accurate and real-time data. Employing a quantitative approach, the researcher conducted a case study, performing tests subsequent to the completion of the dryer's assembly. These tests encompassed temperature measurements on both the core and periphery of the paraffin medium, as well as at the lower, middle, and upper sections of the heat pipes. Diverse voltage levels (150V, 180V, 200V, 220V) and two distinct airflow velocities (1 m/s and 2 m/s) were implemented. The study yielded a noteworthy finding: at 200 volts and a 2m/s airflow, a stable temperature of 94.8 ºC was maintained for an impressive duration of 1 hour and 5 minutes during testing. This promising outcome holds significant implications for enhancing the system's efficiency.
