Silence may be golden for urban turbine: Yeloblade is developing silent wind turbines that can be installed on any roof

To make wind energy generation possible in towns and cities, Galway startup Yeloblade has developed a new turbine that’s both compact and silent, and can sit on a flat roof.

“Traditional wind technologies can’t be used in urban locations due to their size, generated noise and also because of planning stipulations,’’ said Yeloblade founder Liam Hanley, who has spent the last five years developing a turbine which is only 1.6 metre high and 1.2 metre wide.
