Electrical Energy Requirements for Accelerator and Fusion Neutrons

An active brine reconcentration system has been incorporated into the design of the University of Illinois half-acre salt gradient solar pond facility. An important feature of the system is its ability to keep precipitation from diluting the brine. Experimental data presented is in good agreement with a numerical simulation model of the evaporation process. The “film”-type evaporation process used in the system efficiently collects solar energy for evaporating water from brine. Parasitic electrical energy requirements for the evaporation system are 1.2 watts per square meter of evaporation surface area.

Abstrak - Perahu merupakan salah satu armada yang digunakan para nelayan untuk mencari mata pencaharian. Namun pada umumnya pada saat perahu nelayan beropesi mengandalkan bahan bakar sebagai penggerak kapal, hal ini sangatlah tidak menguntungkan mengingat harga bahan bakar semakin mahal. Pada penelitian ini akan membahas desain dan perhitungan daya listrik penggerak perahu nelayan dimana enegi listrik didapat dari energi surya. Dengan adanya sistem pemanfaatan energi surya ini akan menghemat pengeluaran nelayan bahkan bisa dikatakan bahwa energi ini merupakan energi cuma-cuma atau gratis. Pada penelitian ini akan dihitung desain bodi perahu dengan kapasitas 2-3 orang, perhitungan kebutuhan alat penggerak, perhitungan kebutuhan energi listrik dan perhitungan panel surya yang akan digunakan. Hasil dari penelelitian ini dapat dijadikan kajian untuk pengembangan perahu ramah lingkungan, ekonomis, dan pemanfatan enegi surya yang merupakan energi terbarukan. Kapal yang dirancang mempunyai dimensi 3 meter dan lebar 1,33 meter dengan kecepatan 3-4 knot dan menggunakan panel surya dengan spesifikasi 150Wp sebanyak 3 buah.Kata kunci: perahu nelayan, energi penggerak kapal, panel surya, energi terbarukan, MPPTAbstract—Boat is one of the fleets that fishermen use livelihoods. But in general, when fishing boats oppose relying on fuel as a boat propeller, this is very unprofitable given the increasingly expensive. In this study will discuss the design and calculation of electric power driving a fishing boat where the electric energy is obtained from solar energy. Solar energy system will save fishermen's expenses. It can even be said that this energy is free energy. In this study the boat body design will be design with a capacity of 2-3 people, calculation of propulsion requirements, calculation of electrical energy requirements and calculation of solar panels to be used. The results of this research can be used as a study for the development of environmentally friendly, economical boats and the utilization of solar energy which is renewable energy. The ship was designed to have dimensions of 3 meters and 1.33 meters wide with a speed of 3-4 knots and uses 3 solar panels with capasity 150Wp.Keywords: fishing boat, boat propulsion energy, solar panel, renewable energy, MPPT

The Impact

This study presents an analysis of a 75 kWp grid-tied solar photovoltaic (PV) system with a grid tie limiter to provide energy requirements for an aquaculture centre in the Eastern Cape province of South Africa. A data acquisition system, comprising power and energy consumption meters, was deployed to measure solar PV generation, demand for the facility, and energy drawn from the utility grid. Statistical analysis was conducted on the data to determine the impact of the solar PV plant in reducing demand from the utility grid throughout the day, and this was extrapolated into monthly and annual contributions by the PV system to meeting the energy requirements. Findings reveal that the annual energy yield for the system was 1 864.29 kWh/kWp. The solar contribution to the total load requirement on a 24 hour cycle was 28% (139.82 MWh) from July 2018 to June 2019. Summer and winter average contributions by the PV system were 62% and 57% respectively for the period of 05:30–18:30. The mean monthly solar fraction for operating the farm between sunrise and sunset was 0.44. Furthermore, a total of 141.07 tCO2 has been avoided due to the operation of the PV system.
