Water pumping for irrigation has a relatively high energy demand, depending on the applied irrigation method. At the same time, there is a considerable energy from the sun during the irrigation period. The solar PV (photovoltaic) technology may be suitable to ensure electric energy for pumping in many cases in agriculture, where the electric network is not available or reduction of the energy costs is wanted. There are some pilot plants for water pumping on the base of solar energy in the world and the spreading of these solar technologies is predictable. The solar energy based pumping process can be approached both in theoretical and experimental ways. In this paper, both the theoretical questions of the solar based pumping process and the experimental results of a model testing pump station powered by PV panels are shown.

In 1982 McDonnell Douglas Aerospace (MDA) and United Stirling AB (USAB) of Sweden formed a joint venture to develop and market a solar Stirling dish system. Eight modules were built and extensively tested from 1984 to 1988. Power production and daily energy-conversion efficiency as determined by field testing were characterized and modeled into a computer program. Included in this simulation are models of mirror soiling rate, wind spillage loss, mirror washing, and other maintenance outage time, operation and maintenance (O&M) costs, and equipment purchase cost. An economic model of a hybrid (combustion) receiver has been included in the simulation for illustrating the value of using solar energy when available and other fuels such as methane, natural gas, hydrogen, etc. when solar energy is not available or adequate. This paper describes the simulation and presents comparisons of the simulation to test data. The simulation also estimates both the O&M expenses and levelized energy costs for different production volumes.

Abstract Crude oil is considered the main source of energy worldwide. Important problems faced by oil transportation methods are spills and unintended releases. Therefore, most technological developments in the field of transportation methods are aimed at reducing emissions, improving efficiency or preventing spills and leaks. Pipeline systems are the safest, most efficient and economical way to transport crude oil. The transportation process suffers from serious problems, such as: asphaltene and paraffin interacting with the structure damages it, pressure drop in the pipes and high energy consumption during pumping. One of the most important economic tasks when transporting oil through a pipeline is to maintain fluidity and reduce the pressure drop along the pipe. This article highlights the latest and most effective development methods that were used to increase the fluidity of crude oil in pipelines, and also examines the possibilities of reducing energy costs for transporting heavy oils and hydraulic resistance of pipelines by creating intermediate solar station devices consisting of a parabolocylindrical concentrator with a tracking system and a solar panel with a converter that increase the safety and environmental friendliness of oil transportation by reducing the risk of accidents. The intermediate solar station uses a renewable energy source and is clean from an environmental point of view, since it does not produce harmful emissions. The use of solar energy as a green alternative to traditional energy carriers makes it possible to increase the productivity of the pipeline by up to 50 %, eliminate energy costs during oil transportation.

The Impact

AbstractModern urban planning in the world is nowadays facing severe problems due to the fast increase of the population and migration from villages to cities, which led countries to implementation of strategy of fast, modern urban planning to meet the needs of the population. Since the 1980s, in a context marked by increasing development in energy costs and by rising attention to the problem of global warming, countries have gradually mobilized to control their energy better and reduce the environmental footprint. However, even if there are some great successes, the deployment of renewable energies is still not well developed in developing countries such as Algeria that mainly uses fossil fuels. Considering the huge potential and good climatic conditions, developing countries should take on renewable energies for their future development. This paper aims to understand the impact of modern urban strategy on the application of solar urban planning. This study will clarify the critical role of solar electricity integration used in determining the urban solar potential in four studied regions located on three different continents: Africa, Europe and North America, in the cities of Ibenbadis (Constantine, Algeria), Saint-Hugues (Quebec, Canada), Saint-Malo (France) and Ambolobozobe (Madagascar). The results obtained will allow a comparison of the calculated solar energy potential of three urban sites, the benefits of reducing carbon dioxide as well as a comparison of solar energy costs on three continents.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
