95 The main element of the anchoring and stabilization system is the fastening of floating sections to the bottom of the reservoir using composite anchors, as shown in Figure 3. An important feature of this system is the ability to adjust the level of the installation in relation to the water level. In the design, composite anchors were made using the pultrusion method from drawn fiberglass and thermosetting polyester resin. Preliminary studies indicate that anchors with a diameter of 60-100 mm will meet the assumed operational requirements. The final dimension will be determined on the basis of complete data on static and dynamic loads for the entire installation. The choice of polyester composite was based on an assessment of its mechanical parameters and resistance to alkaline and acid solutions, a wide range of resistance to low and high temperatures, and resistance to UV rays. The attachment to the bottom of the tank was designed by pressure injection of a two-component organic-mineral adhesive into prepared holes. The pull-out resistance of such an attachment will be checked in the next stage of testing. Figure 3 – Anchoring diagram with a description of the main system components 4. SINGLE WIRE ENERGY SYSTEM (SWET) In the scientific literature and in several SWET patents, Nikola Tesla’s patent (Tesla, 1897) is widely regarded as the prototype of single-wire electric power transfer. Single-wire electric power transmission has been in use since 1925. The theoretical foundations of this approach were developed by Lloyd Mandeno (Mandeno, 1947), who was the first to implement the system in New Zealand, where it became known as SWER (Single Wire Earth Return). Since then, more than 200.000 km of such lines have been constructed worldwide. The theoretical background of 50/60 Hz SWER systems is well established in the literature, with the main challenges being grounding resistance, electromagnetic field distribution, and overall efficiency (Bolshev et al., 2023; Jin et al., 2023). The primary motivation for deploying SWER lines is economic, as their investment cost is approximately three times lower than that of conventional three-phase lines. However, SWER systems also exhibit several disadvantages, including high transmission losses (up to 50%), relatively high line voltages (typically 12-19 kV), significant voltage drops at the customer end, stringent grounding quality requirements (ground resistance below 5 Ω), and other grounding-related issues. Recent advances in transistor-based resonant power converters enable the generation of high-
