The Archimedes turbine and what independent measurement showed

The reposted video from The Energy Shift presents the Archimedes, a spiral turbine by Dutch designers, as quiet, able to catch wind from any direction and suited to rooftops. It says the design was banned by a power company, without naming the company or the country. The post's text cautions that the shape alone does not guarantee efficiency.

Independent measurement supports that caution. A 2026 thesis by Tauri Kilk at the Estonian University of Life Sciences monitored an Archimedes-type Liam F1 for two months in a residential area of Tartu. Production stayed well below the manufacturer's figures, due to low installation height and turbulence from houses and trees.

Set against the catalogue, the measurement changes the buyer's math. A household turbine's payback depends on the wind at the exact installation point, data that rarely exists before purchase.

The answer is to measure wind on site before investing. The catalogue curve describes the product. Performance depends on the roof.
