The LPSA technology offers a unique, low-cost, low-tech, “green” alternative to wind turbine masts and the loss of valuable land to “wind farms”. LPSA wind towers are light, modular structures that can be fast-assembled with hand tools and no heavy lifting equipment. Most importantly, these towers can accommodate multiple wind turbines at and near the top of the tower. The lower parts of the tower can still be used as greenhouses, regular houses, offices or workshops. The pictures above depict a hexagonal tower using 1.2 m (4 ft) long SDT (small diameter timber) members. The two details (to the right) show various types and arrangements of VAWTs (vertical axis wind turbines): 12 small turbines (top, right) and 2 larger turbines (bottom, right).. The picture to the left shows the concept of a spiral staircase that would provide easy access to the top of a tower. Clusters of LPSA towers would allow a large number of turbines and more efficient use of the land underneath. All the above applies to solar collectors as well.

LPSA towers for Wind Turbines and Solar Collectors

NEW: LPSA towers and spiral staircases

The LPSA technology offers a unique, low-cost, low-tech, “green” alternative to wind turbines/solar collectors support structures and the loss of valuable land underneath.  LPSA towers (masts) are light, modular structures that can be fast-assembled with hand tools and no heavy lifting equipment.  Most importantly, these towers can accommodate multiple wind turbines/solar collectors at and near the top of the tower.  The lower parts of the tower can still be used as multi-storey greenhouses, regular houses, offices or workshops.  The rough pictures above depict a proposed hexagonal tower using 1.2 m (4 ft) long SDT (small diameter timber) members.  (Tensioning elements not shown).  The two details (to the right) show various types and arrangements of VAWTs (vertical axis wind turbines): 12 small turbines (top, right) and 2 larger turbines (bottom, right)..  The picture (bottom left) shows the concept of a spiral staircase that would provide easy access to the top of a tower.  Clusters of LPSA towers would allow a large number of turbines and more efficient use of the land underneath.  All the above applies to solar collectors as well.
