Berkeley's Flying Drone - No Moving Parts
Ionocraft - Size of a Penny Source: UCal Berkeley No Moving Parts, Just Electricity And Ions Ionocraft is being called the world's smallest flying drone. It's powered by ion thrusters and is breakthrough drone innovation from University of California Berkeley. Small and Silent The flying drone measures 2 cm x 2 cm, weighs just 30 mg and is the size of a penny. When it flies it is completely silent. The concept behind this is electrohydrodynamic thrust or EHD. The concept has been around for many years but never applied to larger EHD craft because of the size of the components involved. The Berkeley team says working as they did on a smaller scale is providing an excellent example of the technology. It's resulted in improved thrust to weight ratio and lower voltage requirements. Ion Thruster Power The team uses a high strength electric field which generates a plasma of ions. In essence, when the ions hit air molecules that generates the th...
