A solar-powered unmanned aerial vehicle built by Airbus has delivered broadband down to Earth
A new invention uses the sun’s energy to pull water from dry air. The solar powered harvester has been developed by researchers from the Massachusetts Institute of Technology and uses porous crystalline sponges to trap, concentrate and condense particles from the air to deliver clean water. These sponge materials are called metal-organic frameworks (MOF) and were originally invented in the […]
