Transforming Wind Turbine Blade Mold Manufacturing with 3D Printing

Innovation in the design and manufacturing of wind power generation components continues to be critical. As a result of this challenge, DOE’s Wind Energy Technologies Office (WETO) and Advanced Manufacturing Office (AMO), both within EERE, are partnering with public and private organizations to apply additive manufacturing, commonly known as 3D printing, to the production of wind turbine blade molds. The traditional method of blade design requires the creation of a plug, or a full-size representation of the final blade, which is then used to make the mold. Creating the plug is one of the most time-intensive and labor-intensive processes in wind blade construction, saving time and money.

SPARTAN (Scalable Probabilistic Application Reconfigurable Tensor Autonomous Network)

The technical founder of Ludwig Computing Inc has been competitively selected for support by Cyclotron Road, a U.S. Department of Energy (DOE) Advanced Manufacturing Office (AMO) Lab-Embedded Entrepreneurship Program (LEEP) through an approved merit review process. Ludwig Computing Inc, supported by the U.S. Department of Energy's Advanced Manufacturing Office through the Cyclotron Road program, has investigated the advantages of probabilistic computing for real-world compute-intensive applications. This research adds to the understanding of alternative computing paradigms by exploring a unique hardware-software co-design that integrates quantum computing methods with nature-inspired problem-solving techniques. The project's focus on areas such as combinatorial optimization, graph analytics, and machine learning demonstrates the potential for significant advancements in computational efficiency and performance. By harnessing natural randomness to streamline large circuits into fewer devices, Ludwig's approach enables massive parallelism, potentially offering higher throughput, speed, and energy efficiency compared to conventional hardware solutions. This work benefits the public by paving the way for more efficient computing solutions that could address complex real-world problems while potentially reducing energy consumption in data-intensive industries.

Wide-Bandgap Electronics Analysis

Electrical energy constitutes 40% of total primary energy consumption in the United States, and this is only expected to increase with broad adoption of electric vehicles and the proliferation of renewables. Building on its existing wide-bandgap (WBG) R&D and analysis activities, researchers at the National Renewable Energy Laboratory (NREL) are investigating new power electronic technologies based on WBG semiconductors, which are essential for advanced electrical energy generation, transmission, storage, and use. This work supports efforts by the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy's Advanced Manufacturing Office (AMO) to identify solutions to address the increase in electrical energy consumption through the development of more efficient power electronic devices.
