Though it’s very common to see solar panels installed on homes, it is still fairly rare to see a wind turbine on rooftops.
But all this is likely to change soon after a Rotterdam-based tech firm, The Archimedes, introduced a new generation of mini windmills for domestic use.
The Liam F1 Urban Wind Turbine is a Small Windmill That Can Be Installed on Any Rooftop
This compact and silent windmill is ideal for any urban setting. For added power, it can combined with solar panels. When the sun is shining, solar cells will produce energy, but in case of a dull day or at night, wind turbines can generate energy for the home.
The Liam F1 is Enough to Take Care of Half of an Average Household’s Energy Use
The 165 pound (75kg), five-foot wide Liam F1 can generate up to 2500 kilowatt-hours of electricity per year, depending upon the wind speed.
The Liam F1 gives much better performance than a conventional windmill. The shape of the cone-like spiral blade allows it to swivel, collect gusts and spin, even when the wind is blowing at angles as wide as 60 degrees from the axis.
