Weather Balloons are used excessively in numerous areas and applications today. High altitude balloons are usually unmanned balloons that may climb up to 40km. We propose a high-altitude balloon system design that is capable of self-tuning itself in order to stay at a predefined height limit . This type of a balloon system may be very useful from monitoring geophysical and atmospheric events but also for a vessel to use technological devices such as relay points. This altitude balancing design also allows to be manipulated using a controlled mechanism and may be easily applied for scientific, engineering and industrial purposes. They are much more economic and they almost use no power when they are compared with the alternative technologies.
