Research ArticleOpen accessIn the abstractEnergy Sources TodayNicolae Petrescu, Florian Ion Tiberiu PetrescuThe paper intends to go through some major energy sources that need to be further developed in order to provide the energy needed for an indefinite period of time. It is proposed that both water and solar energy, as well as wind energy together with nuclear energy, are important, but other modern energy sources capable of generating energy directly or … …Energy Research Journal, Vol. 10, Issue 1 · 21 Aug 2019 · 6,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Assessment of Solar Chimneys: Part I – Impact of Chimney Height on Power OutputErdem Cuce, Pinar Mert CuceSolar chimney is a truly sustainable and green energy technology, which is a potential alternative to carbon-based energy economy. The working principle of solar chimneys is based on the buoyant nature of air to turn a turbine that produces electrical power. Solar chimneys are highly in the centre of interest among all solar energy applications since they enable both day … …Energy Research Journal, Vol. 10, Issue 1 · 29 Jun 2019 · 8,200 accessesView PDFCite
EditorialOpen accessIn the abstractFuel Crisis vis-à-vis Green FuelSusmita KamilaThe real sense of crisis often leads to bring some changes for betterment of society. We are in an age, where every day we are facing the crisis of energy. Decisions on current energy as well as fuel crisis in right direction can bring about a better, more sustainable future for our planet. We have huge opportunities and scope for … …American Journal of Applied Sciences, Vol. 16, Issue 2 · 4 Mar 2019 · 7,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Production of Anhydrous Bioethanol using Glycerol and 1-Butyl-3-Methylimidazolyl-Tetrafluoroborate in the Aspen Plus SimulatorJosé Izaquiel Santos da Silva, Lílian da Silva Félix, Mariana Martins Vieira et al.Biofuels are present in the global scenario as an energy source derived from organic biomass, representing an economic and environmental alternative. They are a renewable source of energy with low rates of pollutants emissions and, consequently, less carbon dioxide is released into the atmosphere. The obtaining of bioethanol is originated from a fermentation process, in which a multi-component mix is … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 16 Jun 2021 · 7,114 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Cobalt, Iron and Ruthenium Catalysts for the Production of Synthetic DieselDayna M. Ortiz Rodríguez, María del C. Cotto-Maldonado, José Duconge Hernández et al.Fossil fuels are currently the world's leading source of energy. Environmental legislations, the high price of fossil fuels, the concern about the supply of these fuels and technological development, makes it necessary to search for alternative sources of energy. The production of clean liquid fuels, such as synthetic diesel from synthesis gas, by Fischer-Tropsch (FT) method, is considered a very … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 29 Apr 2020 · 7,256 accessesView PDFCite
Review ArticleOpen accessIn the abstractNikola TESLARelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Nicolae Tesla, has remained and spent most of his life, making it hard to pronounce "Teslea"), is considered to be the inventor of the alternating current and uncovered cableless power transmission. It is attributed to the transmission of energy through monophase, biphasic, polyphase alternating currents and transmission of non-wired energy by electromagnetic waves (oscillations) in the industrial alternating current frequency … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 6 Nov 2017 · 13,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Energy for Aerospace VesselsRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.The advances in solar technology and electric propulsion now offer the promise of new, very capable space transport systems that will allow us to effectively explore the solar system. NASA has developed many concepts of space-powered spacecraft with power levels ranging from tens to hundreds of kilowatts for robotic and asteroid-driven missions and Mars. This paper describes two electrical/chemical propulsion … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 4 · 4 Nov 2017 · 8,019 accessesView PDFCite
EditorialOpen accessIn the abstractAn Opportunity for the Agricultural Sector: The Renewable Energy SourcesRiccardo Testa, Salvatore TudiscaToday, among the most important issue for energy decisions by policymakers, there are security challenges and environmental impacts on climate change and economic aspects. Since the seventies, in fact, global warming and environmental issues have had an increasing importance in international debate, attracting the attention of several scientific studies (Landi and Benelli, 2016). Many of these studies denoted that over … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 6 Sep 2016 · 8,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Simulation and Optimum Operation Strategy of a Trigeneration System Serving a HospitalFrancesco Calise, Massimo Dentice d'Accadia, Luigi Libertini et al.This paper presents a numerical analysis of a trigeneration system in a hospital, aiming at determining the cost-optimal operating strategy as a function of the energy demands to be matched. The system includes: A natural gas fired reciprocating engine, heat exchangers for waste-heat recovery, a single-stage LiBr-H2O Absorption Chiller (ACH), a cooling tower, pumps, a backup boiler, a backup vapour-compression … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 29 Aug 2016 · 8,183 accessesView PDFCite
