‘Wind Tree’ Proves the ‘Silent Wind turbine’ Oxymoron False

Noisy, Monstrous, Nauseous, giant, unpleasant, bird scaring are  some of the properties that flash in our mind when we think about wind turbines. But, not anymore. Because, a French company, ‘New Wind’ has changed this definition.

‘Wind Tree’ can be defined by characteristics like silent, tiny, noiseless, pleasant, beautiful, green – not only in purpose but also in looks and possibly bird friendly. It tapped the main difference between an original tree and a wind turbine. What the leaves of a tree can do but not the blades of a large wind turbine – Being sensitive to light breezes. Just like leaves, Wind Tree’s blades are sensitive even to the light breezes.

The 26 ft (8 m) Wind Trees consists of 63 aeroleaves – leaves that house tiny blades that can generate electricity even in the slightest wind speeds – speeds as low as 4.5mph (7kmph), irrespective of the wind direction.

Except for the little variations due to the wind speed and the location of the tree, the normal power output of a Wind tree is 3.1 kW with the potential to generate 3500kWh to 13,500 kWh a year. In other words, a Wind Tree could supply enough to power 15 street lamps  for a year or bear 83 percent of the annual electrical consumption of a typical family household or one electric car for 10,168 miles (1,360km) over the course of a year. Another major improvement from past designs is that Wind tree being silent. No sound pollution complaints.

He admits there are more consistent winds 160ft in the air but they require ‘monstrous machines’, far from where energy is consumed, Daily mail noted. It quoted, Mr. Michaud-Lariviere said the tree is profitable after winds of 7.8mph (12.5km/h) on average over one year.

Wind Tree,  the very unconventional wind turbine that fits in a backyard, retails at $33,670.

The first Wind Tree would be installed at the Place de la Concorde in Paris. Soon, they would appear all around the French capital and even beyond.

Mr. Michaud-Larivière hopes to develop, in future, a ‘perfect tree that has leaves with natural fibers, roots that could generate geothermal energy and ‘bark’ covered with photosensitive cells. Perhaps, in future, we would find one in every backyard meeting the power demands of the household.

  1. This is a scam. The quoted power of 3.1-kw is pure fabrication. The only way these “Leaves” can even turn at all is when there is no torque, thus no power output.
    If you have ever tried pedaling a generator at a science museum, you would know how hard you have to pedal to light up a 100 Watt lightbulb. Then multiply this by 31 times, which would surely snap this scam tree.

  2. Total nonsense – this is an inefficient drag turbine. No wind = no power. There is almost nowhere you can site that near a house that will generate 3kW.
