What's Happening?
Scientists at Virginia Tech have engineered a method to make ice move autonomously on a specially designed metal surface. This innovation involves creating flat metal plates with V-shaped grooves in a herringbone pattern, which guide the melting ice disks forward without external force. Inspired by the natural phenomenon of 'sailing stones' in Desert Valley, the researchers aim to utilize this self-propelled ice for rapid defrosting and energy harvesting. The study, published in ACS Applied Materials & Interfaces, demonstrates the potential for passive ice removal and microtransport systems, which could lead to advancements in anti-icing technologies and self-cleaning surfaces.
