NREL Looks Beyond 3D Printing Tech To Automate The Building Of Ultra-Tall Concrete Wind Towers
Fascinating short film from the National Renewable Energy Laboratory (NREL) about how they began using 3D printing technology ideas as a basis to work on a project to address one of the main problems of modern wind turbines.
The problem they are attempting to solve is that as there is a demand for an increased height of the wind turbine tower to capture stronger and faster winds – this creates constraints, such as transportation difficulties, created by the increased size of the tower bases needed.
the average US wind turbine has stayed at a height of around 80 meters for the last 10 years
They note that the average US wind turbine has stayed at a height of around 80 meters for the last 10 years due to the difficulties in transportation, but the Lab-Corps project undertaken by NREL has found a potential solution – the use of automated concrete manufacturing.
