Niniejsza praca dotyczy zapewnienia zasilania w energię elektryczną budynku (domku) letniskowego. Wykorzystano do tego celu odnawialne źródła energii w postaci turbiny wiatrowej oraz paneli fotowoltaicznych współpracujących z magazynem energii w celu zbilansowania produkcji oraz zapotrzebowania na energię. Na podstawie danych meteorologicznych i szacowanego profilu obciążenia wykonano symulację pracy całego układu, co pozwoliło na ocenę pracy instalacji w zakresie technicznym oraz ekonomicznym.

This paper deals with the problem of providing electricity for a summer building (house). The installation of renewable energy sources in the form of a wind turbine and photovoltaic panels, cooperating with an energy storage in order to balance production and energy demand, was used for this purpose. Based on the meteorological data and load profile, a simulation of generation and consumption of energy was performed, which enables the technical and economic assessment of the installation.

Geochemical studies (WD-XRF, ICP-MS, and GF-AAS) have shown that polymetallic nodules from the eastern Clarion-Clipperton Zone (CCZ) in the Pacific Ocean are enriched in several metals such as Cu (mean 1.16%), Ni (1.15%), Co (0.15%), and Zn (0.14%), as well as remarkable contents of Mo (0.059%), V (0.04%), Ce (0.019%), Nd (0.011%), Li (0.015), and Pt (43 ppb). The average content of REE, together with Y and Sc, is 620 ppm. In nodules from the CCZ metal concentrations are often much higher than those reported in nodules from other ocean basins in the world. The bulk-nodule mean value of the Mn/Fe ratio is 5.3, which is characteristic for a mixed (hydrogenetic and diagenetic) origin of the nodules. Microprobe investigation revealed two different chemical compositions of the layers, and ascertained their general metal content. The nodules analyzed are composed mainly of concentric-collomorphic laminae of Mn and Fe (oxy)hydroxides which crystallized around mineral nuclei (e.g., quartz, clay minerals), bioclasts or rock fragments. They are from 3.3 to 7.6 cm in diameter. The chemical and physical properties of the laminae allowed distinction of two genetic types: hydrogenetic and diagenetic. Those formed as a result of hydrogenesis had increased values of Co, Si, Cl and S, while formed diagenetically showed increased levels of Cu, Ni, Mg, Zn and K. These lamina types are characterized by different growth structures, reflectivity, density and Mn/Fe ratios. The ratio of the diagenetic layers to hydrogenetic layers (192/53) in representative polymetallic nodules shows that the nodules of this study are of mixed hydrogenetic-diagenetic type. A mixed genesis was also shown by discriminant diagrams, with these CCZ samples being located at the transition between typical hydrogenetic and diagenetic fields.

In the shadow of discoveries of large deposits of mineral resources in Poland after World War II, intensive exploration works were carried out, but the results of this research did not bring such spectacular effects. Exploration of Zn-Pb deposits conducted in the vicinity of historic deposits of Tarnowskie Góry and Bytom led to documentation of the Zawiercie, Goluchowice and Marciszów deposits. With some successes, exploration works of metal ore deposits in Paleozoic igneous and metamorphic rocks of the NE margin of the Upper Silesian Coal Basin were carried out. In this area, the Myszków Mo-W-Cu mineral deposit was confirmed, representing the porphyry copper genetic type. Moreover, in the area of Mrzyglód, the promising mineralization zone was found, requiring further geological research. The exploration of uranium and rare earth element ores did not lead to documentation of the deposits, nevertheless they made it possible to recognize all geological structures in Poland in terms of the possibility of occurrence of ore deposit occurrence of these metals. The prospecting works for these goals was carried out with a relatively small scale and were limited of the Sudetes, where exploitation took place on a fairly large scale in the past (Zloty Stok, Radzimowice, Klecza-Radomice, Wądroże Wielkie). The gold concentration occurring in the Zechstein Kupferschiefer formation and the porphyry copper mineralisation in NE margin of the Upper Silesian Coal Basin were also studied. The PGI participated in the exploration of mineral resources in marine areas, where besides the hydrocarbon exploration in the Polish economic zone, research on the Baltic polymetallic nodules was carried out, and within the INTEROCEANMETAL consortium the raw material potential of the Clarion-Clipperton Zone in the Pacific was studied.
