Most people in Indonesia usually have plants at their homes, places of business and so on. Balad is a place of business, which has a minimalist garden on the second floor. The limited land owned by Balad has made business owners take advantage of the existing land conditions to raise crops on a small scale. The garden is usually planted with a variety of plants to beautify and make the gardens in Balad cool. Plants grown by business owners in order to grow properly must have adequate water consumption and adequate lighting. The provision of water or watering and lighting to plants is one of the important things to keep the plants alive. Seeing this condition, business owners must do regular watering so that these plants get sufficient water consumption. Nowadays everyone has their own preferences, the same applies to business owners in Balad, so that sometimes they are forgotten to care for plants due to limited time. Information systems on plant care based on the Internet of Things help in collecting information related to conditions such as humidity, temperature, soil fertility, and plant inspection that can be controlled via a smartphone using the internet network. Internet of Things makes use of plant owners to connect with their residence or place of business from anywhere and anytime. The remote sensor structure using Microcontroller ESP8266 is used to monitor the condition of plants in the Balad park, of course, to see conditions remotely. Designing Plant Care Information Systems based on the Internet of Things, can reduce costs and update productivity standards in maintaining small-scale plants and if needed can be developed on a large scale

This work presents a detailed model of performance of Stirling engines which is expected to be of interest for the Concentrated Solar Power community. In effect, gas turbines of different types have been proposed for small and medium scale solar applications based on their reduced (even inexistent) water consumption and modularity. In the medium to large scale, conventional steam turbine based plants demand high investment costs as well as high operation costs (mostly due to water consumption). In the small-scale it is the Stirling engine which is generally consider as the prime mover of choice due to its high efficiency at moderate temperatures. In this context, this paper describes a detailed model of performance of Stirling engines. The model includes frictional and mechanical losses, heat transfer within the engine and other features like auxiliary power consumption and applies to both on-design and off-design operation. The validation of all these capabilities is also presented in the text. Hence, the model is expected to provide a valuable tool for individuals who need to assess the performance of externally heated piston engines.

Architecture and Design, whether developing ideas in creative process or implementing projects, are not out from the emerging challenges that involve people and environmental well-being. Created by its own community in a specific place, vernacular design is a fundamental identity expression of these individuals, their relationship with its territory and, at the same time, the cultural diversity of the world. This article express the importance of vernacular for essential sustainability issues, specifically related to future critical scenarios of water consumption in small scale food self-production. Moreover, this research will illustrate these important topics throughout the exhibition “Prato do Que” (2019), developed by Museum of Tomorrow, with the Laboratório de Investigação em Livre Desenho (LILD - Brasil) and Universidad del Bío-Bío, Chile.

The increased demand for water resources due to urban population and economic growth has worsened the urban water crisis. In order to address this issue, a policy of “developing a water-saving society” (namely, water-saving society policy) has been implemented in some Chinese cities. This study takes 285 cities at the prefecture level and above as the sample and uses the propensity score matching (PSM) method to analyze the effect of China’s urban water-saving society policy on the reduction of water consumption per CNY 10,000 gross domestic product (GDP) from 2005 to 2017. The results show that the water-saving society policy significantly (p < 0.01) reduced water consumption in the study period; however, the effects differed between cities with different water resource endowments, economic development level, and urban scale. Specifically, there was a positive water consumption reduction effect in cities in humid areas, with low economic development, or of large scale, while the effect was limited in cities in arid areas, with high economic development, or of small scale. Therefore, for areas where water resource supply is insufficient, water-saving policy should be designed and implemented suiting local conditions, and it is also necessary to explore more water sources.

In this study, a combined experimental and computational study for the design of a low water consumption cooling tower is performed. The purpose of the study is to reduce the water consumption without decreasing the efficiency of a typical cooling tower. To achieve this aim, it is necessary to enhance the homogeneity of mist/air mixture. For this purpose, firstly, an experimental set-up including a small scale wind tunnel is installed which provides opportunity to examine different inlet and outlet configurations easily. Computational Fluid Dynamics (CFD) is used extensively to examine the effects of different configurations before experimental studies. Simulations of different inlet and outlet configurations are performed using only air. Several turbulators are designed and simulated to increase the turbulence levels. A three dimensional multi-phase CFD model is utilized to design a nozzle-turbulator system for the cooling tower. As results of the computational and experimental studies, the most efficient inlet and outlet configurations are specified and turbulators are selected from the alternative designs.

High performances and operation with low water consumption are mandatory but not sufficient conditions for the Combined Cycles Units implementation in the terrestrial propulsion systems field. There is another restrictive condition, which refers on the admitted size. That is why a dimensional analysis of the Combined Cycles Units is mandatory. In this view, paper presents the results of the dimensional analysis of a small scale Combined Cycles Unit for terrestrial propulsion, based on a two-pressure-levels Steam Cycle and operating with liquid fuel.
