Dutch startup Archimedes has introduced a unique home wind generator Liam F1. It promises to surpass solar panels in efficiency. The device uses 3 Archimedes spirals instead of traditional flat blades. This is a key element in the success of the Liam F1. The design eliminates the need for complex orientation systems, making the device easier and more reliable to operate. The spiral blades are virtually silent, which is especially important in urban areas. Tests in Rotterdam have shown that at an average wind speed of 5 m/s, the wind turbine generates about 1,500 kWh of electricity per year. This makes it more efficient than solar panels of similar cost. The compact size of the device (the turbine has a diameter of 1.5 meters) allows it to be installed on rooftops and in limited urban spaces. In the Nordic countries, the cost of a turbine is about 4,000 euros. Despite high electricity tariffs, the payback period for the device in the Netherlands can take at least 8 years, while in countries with lower tariffs, this period can stretch for decades
