Summary: | A future large radio array for the detection of neutrinos may need to be built in remote areas withoutaccess to a power grid, such as the Antarctic ice-shelf or Greenland. In such a scenario lifetimewill need to be optimized by combining different renewable and autonomous power sources.The ARIANNA experiment on the Ross-Ice-Shelf has run stably on solar power during the Australsummer, as soon as the Sun was more than 3 degrees above the horizon. However, the darkmonths of polar winter provide essential lifetime, especially with respect to multi-messenger studies.We will present a wind-turbine that has been custom-designed for the ARIANNA experimentto be radio-quiet, sensitive to low winds and able to sustain extreme Antarctic weather. The firstimportant milestone was achieved in 2018 when a first wind turbine survived the winter monthsand powered a station for 24% of the winter time. We will report on the in-situ performance ofthe second-generation turbine already reaching 39% uptime during the weak summer winds andthe perspective of this technique. |
