    This is the interesting master project of a good friend from my university, not really related to space though. Replacing the drone's wifi antenna by an Avalanche Victim Detector, it could be a very promising tool to deploy the first avalanche searches.

    In remote / under-developed regions this might actually be a strong alternative for building internet connectivity - somewhat like the exploding market for cell phones in Africa due to the lack of land lines.

    We present the design and experimental implementation of a power harvesting metamaterial. A maximum of 36.8% of the incident power from a 900 MHz signal is experimentally rectified by an array of metamaterial unit cells. We demonstrate that the maximum harvested power occurs for a resistive load close to 70 Ω in both simulation and experiment.

    nice overview of the 3 main space related projects attempting to bring internet access to the world, namely SpaceX+Google micro-satellites network, OneWeb+Virgin Galactic OneWeb and Project Loon by Google. not a lot of technical details though...
