The more bees in a colony, the more combs with honey.
The micro-turbines have been optimised over years of research and field tests. They are extra quiet, and can generate energy individually or as part of a more complex system.
In terms of manufacture, installation, maintenance and transport, they represent better value than larger wind turbines.
Versatility is also a defining feature. They can be installed on the roofs of office buildings, factories or private houses, as well as on electricity masts, and are operated digitally.
