Nanotechnology can be a powerful weapon in creating competitive advantages in the energy market, through the use of the photovoltaic nanopanels, which may reduce production costs and simultaneously permit to achieve the socio-environmental requirements. Moreover, today the adoption of nanotechnology in energy production can make this kind of energy very interesting along the years. Nanotechnology may, in fact, be responsible for unimaginable gains, both economically and for preserving the planet. The use of nanotechnology in the industry production processes is evidenced in this article. The example of the electric energy produced by photovoltaic panels is the vehicle to do so. The competitive advantage associated to the use of nanotechnology to solar energy production for companies in this market segment is highlighted. Finally, in addition to the already existent nanopanels, another opportunity to revolutionize the market, already in sight, is presented: the Nanogenerators that can convert the mechanical energy of body motion in electricity.

The present article discusses the institutional model adopted in Brazil regarding energy production through biomass. The utilization of renewable energy and clean sources of energy is a characteristic of Brazil’s energy matrix. Recently, the production of energy through biogas—and biomass in general—started to gain force. The concessionaires of energy, as well, started to discipline its utilization and selling, creating an impediment to the commercialization of energy produced by micro or mini generation outside the free energy market, as well as a prohibition of binding the contracts to the value of electric energy. Even though, it is possible to create a network of contracts that interconnect the producers and the consumers. In this line, the theoretical-empirical method was used to conclude that the model’s difficulties—and specially the legal limitations—can be overcome by adopting a network of contracts capable of subjecting renewable energy generation to an energy compensation model.

Poland is dynamically changing its energy mix. As a result of this process, solar energy is increasing its share in energy production. The development of the solar energy market is determined by numerous factors. This paper aims to develop a roadmap for further development of the photovoltaic (PV) energy market in Poland. The scope of the research covers five areas of PV technology and market development in Poland: (i) technology; (ii) power grids; (iii) law; (iv) economic conditions; and (v) social conditions. With the use of a Technology Roadmapping Methodology (TRM), for each of the determined areas, several factors were analyzed, and their development paths were described. In addition, the article focuses on technological challenges (regarding PV cells, modules, components, power conversion and monitoring and management system, optimizers, batteries, and other energy storage systems), grid efficiency, recycling, production costs, subsidies, public awareness and education, and the energy exclusion problem. The main result of the research is the roadmap of the photovoltaic solar energy technology and market development in Poland. Further development of the PV market and technology requires parallel progress in all the identified areas. This study offers implications for policymakers, investors, managers, and technology and infrastructure developers regarding their involvement in photovoltaic market.

The balancing of the power of the Polish Power System (KSE) is a key element in ensuring the safety of electric energy supplies to end users. This article presents an analysis of the power demand in power systems (PS), with emphasis on the typical power variability both in subsequent hours of the day and on particular days and in particular months each year. The methodology for calculating the costs of electric energy undelivered to the end users and the amount of these costs for KSE is presented. Different possibilities have been analyzed for balancing power systems’ peak load and assumptions have been formulated for calculating the amount of the related costs. On this basis, a comparative analysis has been made of the possibility to balance peak load using operators’ system services, trans-border connections, and various energy storage solutions. On the basis of the obtained results, optimal tools have been proposed for market-based influence from transmission and distribution system operators on energy market participants’ behaviors in order to ensure the power systems’ operating safety and continuous energy deliveries to end users.

AbstractElectric energy generation from falling droplets has seen a hundred-fold rise in efficiency over the past few years. However, even these newest devices can only extract a small portion of the droplet energy. In this paper, we theoretically investigate the contributions of hydrodynamic and electric losses in limiting the efficiency of droplet electricity generators (DEG). We restrict our analysis to cases where the droplet contacts the electrode at maximum spread, which was observed to maximize the DEG efficiency. Herein, the electro-mechanical energy conversion occurs during the recoil that immediately follows droplet impact. We then identify three limits on existing droplet electric generators: (i) the impingement velocity is limited in order to maintain the droplet integrity; (ii) much of droplet mechanical energy is squandered in overcoming viscous shear force with the substrate; (iii) insufficient electrical charge of the substrate. Of all these effects, we found that up to 83% of the total energy available was lost by viscous dissipation during spreading. Minimizing this loss by using cascaded DEG devices to reduce the droplet kinetic energy may increase future devices efficiency beyond 10%.

AbstractSelf-powered implantable devices have the potential to extend device operation time inside the body and reduce the necessity for high-risk repeated surgery. Without the technological innovation of in vivo energy harvesters driven by biomechanical energy, energy harvesters are insufficient and inconvenient to power titanium-packaged implantable medical devices. Here, we report on a commercial coin battery-sized high-performance inertia-driven triboelectric nanogenerator (I-TENG) based on body motion and gravity. We demonstrate that the enclosed five-stacked I-TENG converts mechanical energy into electricity at 4.9 μW/cm3 (root-mean-square output). In a preclinical test, we show that the device successfully harvests energy using real-time output voltage data monitored via Bluetooth and demonstrate the ability to charge a lithium-ion battery. Furthermore, we successfully integrate a cardiac pacemaker with the I-TENG, and confirm the ventricle pacing and sensing operation mode of the self-rechargeable cardiac pacemaker system. This proof-of-concept device may lead to the development of new self-rechargeable implantable medical devices.

<p>As coastal production costs in many countries, producers are moving inland to remain competitive with other<br />countries. Also, container transport volumes continue to grow, the sea flow generates almost proportional inland<br />flow; the links with hinterland will become critical factors for the seaports functionality. Development of dry<br />ports is an important part of intermodal transport which play an important role in improving hinterlands.<br />Successful implementation dry port depends on identification and description of required capabilities to develop<br />advanced intermediate terminal, discover existing deficiency in these capabilities and their effects of each other.<br />This article fill the gaps of implementation of dry ports by offering a conceptual model. To do so, this current<br />study is done in a complicated process in five stages of: review of literature, Delphi, Gap analysis, fuzzy<br />Dematel and Structural equation modeling (SEM). 17 indexes of Delphi model were extracted and classified in 8<br />groups. The identified gap and causal relations enabled presentation of a model which was tested and verified by<br />Partial Least Squares (PLS).</p>
