Here at Treethinker we love a vertical axis wind turbine, put in the shape of a tree and we’re obviously going to fall in love.
Jérôme Michaud-Larivière – A French entrepreneur – has designed and built a wind tree that is more aesthetically pleasing than the traditional Wind Turbine.
The Tree’s measure 11m (36feet) tall and 8m (26feet) in diameter, they also run relatively silently! Could this be a new era for wind?
Each tree has 72 ‘leaves’ which act as turbine blades for micro turbines on each ‘branch’
The tree can generate power at low wind speeds of as a little as 2 meters per second, speeds which are generally missed by larger wind turbines optimised for airflow outside of the boundary layer (The area in which wind speed is decreased by friction from the ground and buildings).
The designers say the power output is 3.1 kW, depending on placement this would be enough to power the average household and save 200kg of Co2 per year per tree.
“Our micro-generators ensure production virtually throughout the year with a production threshold lowered to winds of less than 2m/s (5.5mph).” Jérôme Michaud-Larivière,
The design team are set to install an operational prototype in Paris in March 2015.
