The thing about these archimedes screw turbines is they are mesmerizing to watch and can produce more than half of citizen's home energy.
This type of turbines blade has solved the noise problem these small household turbines have been known for.
The Archimedes is a Dutch renewable energy company that specializes in these small household wind turbines.
They claim this Liam F1 wind turbine can generate 1500 kWh of energy a year starting at wind speeds of only 5 m/s.
When used in combination with rooftop solar panels, a house could run off grid. “When there is wind you use the energy produced by the wind turbine; when the sun is shining you use the solar cells to produce the energy,” The Archimedes CEO Richard Ruijtenbeek said.
The Liam’s blades are shaped like a Nautilus shell. The design allows it to point into the wind to capture the most amount of energy, while also producing very little sound. The inventor of the turbine Marinus Mieremet says that the power output is 80 percent of the theoretical maximum energy that could be harnessed from the wind.
“Generally speaking, there is a difference in pressure in front and behind of the rotor blades of a windmill. However, this is not the case with the Liam F1. The difference in pressure is created by the spatial figure in the spiral blade. This results in a much better performance. Even when the wind is blowing at an angle of 60 degrees into the rotor, it will start to spin.
