Although cities are typically windy places, we currently have no means of harvesting that resource now. That’s why a duo of university students have created an mini-wind turbine that allows people in dense urban areas to generate energy from their apartment balconies. The innovative turbine has a sliced surface that allows wind to flow in all directions, which let’s it produce energy no matter which way the wind blows. This powers a generator that converts the energy into electricity that can either be used directly or fed into the grid.
