I am thrilled to announce that our recent work entitled: The Integration of Internet of Things and Machine Learning for Energy Prediction of Wind Turbines https://lnkd.in/dMzZPXX5 has been published in Applied Sciences journal (IF 2.5). This work is based on the diploma thesis of Mr Christos Emexidis, graduate student in the Department of Digital Industry Technologies of  the National and Kapodistrian University of Athens. The main goal of this work is to combine the IoT technology with machine learning in the wind energy sector by processing weather data acquired from sensors to predict wind power generation. Both the advantages and shortcomings of the three studied regression models  indicate that their integration with IoT devices will facilitate successful energy prediction.

📊 Three different regression models are evaluated. The models under comparison include Linear Regression, Random Forest, and Lasso Regression, which were evaluated using metrics such as coefficient of determination (R²), adjusted R², mean squared error (MSE), root mean squared error (RMSE), and mean absolute error (MAE). Moreover, the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) were taken into consideration as well. ⚙ 🔋 After examining a dataset from IoT devices that included weather data, the models provided substantial insights regarding their capabilities and responses to preprocessing, as well as each model’s reaction in terms of statistical performance deviation indicators.

Device that turns Wi-Fi signals into electricity created by scientists This rectifier is designed to operate at extremely low power levels, even below -20 dBm, overcoming the limitations faced by conventional technologies. Updated: Jul 25, 2024 06:39 AM EST Aman Tripathi • he team optimized the spin-rectifiers, ensuring effective operation across various power levels. FabrikaCr/iStock A research team led by the National University of Singapore (NUS) has made a significant stride in energy harvesting technology. This innovation could potentially eliminate the need for batteries in various electronic devices. They have developed a new type of rectifier that can efficiently convert ambient radio frequency (RF) signals, typically considered as “waste” energy, into usable direct current (DC) voltage For reference, their novel technology converts ambient RF signals from sources like Wi-Fi and cellular networks into usable electricity. “RF energy harvesting technologies, such as this, are essential as they reduce battery dependency, extend device lifetimes, minimize environmental impact, and enhance the feasibility of wireless sensor networks and IoT devices in remote areas where frequent battery replacement is impractical,” stated the press release. Harvesting ambient RF electromagnetic signals The research demonstrated the use of nanoscale spin-rectifiers (SR) to achieve this conversion. They did it even at low RF power levels below -20 dBm, a threshold where existing technologies struggle. “We optimized the spin-rectifiers to operate at low RF power levels available in the ambient, and integrated an array of such spin-rectifiers to an energy harvesting module for powering the LED and commercial sensor at RF power less than -20 dBm,” explained Professor Yang Hyunsoo of NUS, who spearheaded the project. The team successfully powered a commercial temperature sensor using this technology. “Harvesting ambient RF electromagneticsignals is crucial for advancing energy-efficient electronic devices and sensors,” said Yang. “However, existing Energy Harvesting Modules face challenges operating at low ambient power due to limitations in existing rectifier technology.” Overcoming existing challenges Traditional rectifiers, like Schottky diodes, face thermodynamic constraints and parasitic effects at low power levels. “Nanoscale spin-rectifiers, on the other hand, offer a compact technology for sensitive and efficient RF-to-DC conversion,” emphasized Yang. It offers improved sensitivity and efficiency. The team optimized the SR devices, creating configurations that operated effectively across a wide power range. “To improve output and achieve on-chip operation, the SRs were coupled in an array arrangement, with the small co-planar waveguides on the SRs employed to couple RF power, resulting in compact on-chip area and high efficiency,” mentioned the researche https://lnkd.in/e3cWFpUD

At University, the administration was grappling with soaring energy bills and complaints from students about fluctuating temperatures in classrooms and dorms. Despite efforts to cut costs, the university’s energy consumption kept climbing, especially with an expanding campus and new facilities. Determined to find a solution, they partnered with Energy Solutions Labs Pvt Ltd , experts in energy monitoring systems (EMS) for large institutions. ESL conducted an energy audit and discovered that the university’s HVAC systems, lighting, and labs were consuming far more energy than necessary—much of it during off-hours. ESL installed sensors across the campus, from classrooms and libraries to sports facilities and dormitories, all feeding real-time data into a central EMS dashboard. The system automatically adjusted heating, cooling, and lighting based on room occupancy and outdoor conditions. It also provided detailed energy reports, enabling the university to spot inefficiencies and predict equipment maintenance needs. Within the first year of using the EMS, the results were remarkable: The university’s energy bills dropped by 20%, saving over RS1,00,000 annually. The system helped optimize HVAC usage and manage power-hungry lab equipment, preventing costly breakdowns and repairs. The university reduced its carbon footprint by 25%, contributing to its sustainability goals and improving its green reputation. Students noticed the difference too: dorms and classrooms became more comfortable, with stable temperatures and better lighting, leading to a 10% increase in student satisfaction. University also earned recognition for its efforts, receiving a Green Campus Award for reducing energy waste and embracing sustainable practices. By adopting an EMS, the university not only saved money but also enhanced the campus experience for students and staff while contributing to a more sustainable future. This simple yet powerful system transformed the university into a model of energy efficiency, proving that sustainability and cost savings can go hand in hand.

Our experiment proved that the proposed solution generates an energy surplus, ensuring energy autonomy and reliability for IoT nodes. This hybrid approach leverages #RenewableEnergy from both light and sea waves, paving the way for more #sustainable IoT solutions. In such a hybrid way, autonomous end node devices can be more reliable being powered by the sun when there are no waves or powered by the waves when there is no sun.

From a Quora Post: Could China dominate high tech? China could and did. Just a simple axiom - You dominate when you can execute. China builds the infrastructure and educates its people. And there’re 1.4 billion Chinese. Lastest census shows Chinese leads in 34 out of 37 high tech fields. And this is because they’re always the first user of technology, consider: First to have nationwide 5G network to optimize IoT and AI. First to have nationwide EV charging network to now have almost half of new car sales in EVs. First to build out nationwide network of high speed rails - 45,000 km in 15 years and to reach 70,000 in 5 years time. Note: U.S. is 0 km. In manufacturing, China has near-monopolies on all key renewable energy supply chains and nodes. Produces a whopping 80% of the world’s solar panels, 60% of its electric vehicles, and more than 80% of its electric vehicle batteries. China also produces 60% and processes almost 90% of the world’s rare earth minerals. Rare earths such as lithium and cobalt are essential components for clean energy manufacturing and infrastructure, including electric vehicle batteries, photovoltaic solar panels, and lithium-ion batteries used for renewable energy storage. China dominates hi tech because they built the infrastructure and invest in building also the ecosystem of supply chain and nodes.
