We present an edge-cylinder geometry for high throughput electrospinning that utilizes a reservoir filled with a polymer solution and a concentric cylindrical collector.  Under high voltage initiation, multiple jets spontaneously form on the fluid surface, rearrange approximately equidistant along the reservoir-edge and spin   (Image of 37 jets electrospinning radially from reservoir-edge) towards the collector.  Edge-cylinder electrospinning produced nanofibers with average diameter of 225 nm and a demonstrated throughput ~40 times higher than the traditional single-needle electrospinning.
