The research in the field of the development of an efficient ground-station is focusing on the following aspects:

• How can the mechanical and electrical efficiency of a ground-station be defined, measured and compared?

• How can the mechanical and electrical efficiency be improved?

• How can the average electrical output power be maximized for a given size of the electrical generator and kite?

• How can the costs of the energy storage be minimized?

• Which properties must a winch control system have, that minimizes the peak forces and maximizes the electrical output?

• How can the mechanical stress for the cable be minimized, to ensure a long lifetime of the cable?

• Which kind of motor/ generator is best suited for this kind of application?
