What does Solve mean by 'powered by technology'? We define technology broadly as the application of science and evidence-based knowledge to the practical aims of human life. We welcome solutions that are using apps, SMS technology, software, AI, robots, drones, blockchain, and virtual reality! We also welcome solutions that are leveraging traditional, ancestral, and natural technologies, and knowledge systems. That could be plant-based solutions that reduce the effects of climate change, biodegradable sanitary pads, or solutions that leverage centuries-old irrigation or building techniques.
