A wind turbine that blends into the neighborhood<\/h2>\n\n\n\n
Focus Online describes the installation in Th\u00fcdinghausen as a 32\u201910\u201d steel trunk with 36 green microturbines mounted on branching arms, set on a concrete foundation and weighing roughly 3.9 tons. <\/p>\n\n\n\n

New World Wind\u2019s data sheet lists 10,800 watts of installed power for a 36-leaf model and a lower nominal power figure of 5,868 watts. That gap is a reality check, and the company\u2019s CEO told local media more than 200 of these “wind trees” are already deployed worldwide.<\/p>\n\n\n\n
Why Harms wants wind when solar is off<\/h2>\n\n\n\n
Harms already has two solar PV systems rated at up to 10,000 watts each, and he told local media he expects the wind tree to make his property more energy independent. Focus Online says his logic is that wind can keep producing when solar is weak, especially at night or during gray winter stretches when the sun barely shows up.<\/p>\n\n\n\n
This is the practical pitch for a hybrid home setup, you stack sources that behave differently across the day and across the seasons. New World Wind also sells hybrid versions<\/a> that add small photovoltaic “petals” to its wind devices, aiming for extra output in sunny locations.<\/p>\n\n\n\nReal output depends on wind, not wishful thinking<\/h2>\n\n\n\n
Each “Aeroleaf” is designed to operate independently, so one failure should not stop the rest from generating. New World Wind says each unit is rated at 300 watts and is designed to start turning at wind speeds of about 8 ft. per second, which is lower than many conventional large turbines.<\/p>\n\n\n\n

Focus Online notes that experts often warn profitability depends heavily on the local wind resource, and it cites concerns that in poor locations the cost of generated electricity can exceed \u20ac1 per kilowatt-hour, making a 20-year payback hard to reach.<\/p>\n\n\n\n
The payback problem is hard to ignore<\/h2>\n\n\n\n
Focus Online puts the total investment for Harms\u2019 wind tree at around \u20ac70,000 ($80,800) including foundation and electrical work, and it contrasts that with a full home solar installation in Germany that it says can come in under \u20ac20,000 ($23,000). <\/p>\n\n\n\n
Even before maintenance, that price gap sets a high bar for small winds to clear.<\/p>\n\n\n\n![\"A](\"https:\/\/techy44.okdiario.com\/en\/wp-content\/uploads\/2026\/04\/homeowner-wind-tree-36-turbines-erase-power-bill-1.jpg\" "\\"\\"")
