These days, the Croatian company Hipersfera presented an autonomous airship, that is designed to fulfill border control and survaillance tasks. It looks like a small sphere in the shape of a camera lense, as it is shown within the video below. This Helium filled sphere is able to float over a survaillance target without making much noise. While the real airship should come in a size of around 40 diameter, the prototype actually offers around 3.5 meter. This announcement comes right after the US Army declared the recreation of traditional airship technology, so it seems as if Zeppelin’s technology is still interesting.
