Base station communication experiment
Here, we propose a large-scale 2-bit millimeter-wave programmable metasurface to build an integrated smart base station framework for 6G communications. The meta-array is composed of 30 × 30 meta-elements, each with two embedded positive-intrinsic-negative (PIN) diodes. The proposed system includes PS-LTE functionalities, mission-critical push-to-talk, proximity-based. . The article covers a major scientific breakthrough in cross-network convergence between fiber-optic and wireless communications. They integrated photonics and ultra-wideband devices, showing seamless. . To serve the maximum number of users in the disaster area without apriori user distribution information, we proposed a 'sweep and search' algorithm to find the optimal deployment of drone base stations. The algorithm involves polygon area decomposition, coverage control and collision avoidance.

Photovoltaic panel hydrogen production experiment
This paper presents the design and optimization of a novel lab-scale green hydrogen production system driven by solar photovoltaic (PV) energy. The system was run for several days and it showed its suitability and capability to produce hydrogen. The quantity of produced hydrogen is linearly. . The increasing recognition of hydrogen as a critical element in the global net-zero transition and its clear role in decarbonizing challenging sectors coincide with the growing urgency to address climate change. Africa's favourable renewable-energy capacity, ranging from 28% to 36% for solar, has. . This study sets forth an experiment of producing hydrogen via utilizing the solar energy through the electrical analysis of the solution of hydroxide sodium whose concentration (2 g/l).

Japan s space solar power generation experiment
The OHISAMA program is designed to test whether harnessing solar power from space is technically feasible. The plan is to launch a 180-kilogram satellite equipped with PV panels into orbit 400 kilometers above Earth, where it will constantly receive sunlight and turn it into. . Japan is preparing to launch OHISAMA: a satellite designed to capture sunlight in space, convert it to microwaves, and beam that energy back to Earth. The satellite, no bigger than a washing machine, is scheduled to launch later in 2026 into orbit roughly 400 kilometers above Earth. The Japan Aerospace Exploration Agency (JAXA) successfully sent power collected by solar panels in space to a ground station using microwave transmission. At the heart of this innovation is a satellite project called OHISAMA, a name which means “sun” in Japanese—a fitting symbol for. . Although earlier experiments have detected signals transmitted from orbit, the OHISAMA project aims to be the first in the world to deliver solar power to a receiving site on Earth and convert it into usable electricity. The satellite will be carried aboard Space One Co.

Solar Photovoltaic Power Generation Design Experiment
Experiment with solar power by building your own solar-powered robot or oven or by testing ways to speed up an existing solar car. Or analyze how solar cells or panels work. . The purpose of this experiment is to analyze the system behavior when the light rays strike the PV panel and a portable rheostat is connected. A second PV panel, connected to the first one in parallel or series, is also available. To prepare for this lab before your session starts, read through the Theory section below; note there is no explicit material on photo cells in your textbook. . Students examine how the orientation of a photovoltaic (PV) panel relative to the sun affects the efficiency of the panel. The following projects allow students to set up. .
