A novel energy pile: The thermo-syphon helical pile [PDF]
Applied Thermal Engineering, 2019 Abstract This study focuses on assessing the heat transfer rate and structural stability of a novel self-operating energy pile based on the principle of a thermo-syphon. Specifically, this new energy pile, referred to as a “thermo-syphon helical pile” (THP), is formed by pressurizing a hollow helical pile with carbon dioxide (CO2) to form a heat pipe,

Axial response and material efficiency of tapered helical piles
Journal of Rock Mechanics and Geotechnical Engineering, 2021 Different techniques have been proposed to increase the bearing capacity of open-ended piles. Welding helices to the shaft and tapering the pile shaft could be used simultaneously to enhance the static and dynamic behaviors of these piles.
