Maximov Space Systems Research Institute

Maximov Space Systems Research Institute (Научно-исследовательский институт космических систем имени А.А.Максимова, or "Maximov institute") is branch of the Khrunichev State Research and Production Space Center (Государственный космический научно-производственный центр имени М.В.Хруничева, or "Khrunichev Center"), dedicated to the development of inertioids ("движитель без выброса рабочего тела").

The "Maximov institute" is widely known due to the perpetual motion machine Gravitsapa that was launched into the Earth orbit in 2008 and advertised in mass media as a great achievement of Russian science and technology.

The director of the "Maximov institute", Valery Menshikov considers it as one of the most efficient branches .

The "Maximov Institute", the Khrunichev Center and personally Valery Menshikov become world-wide known after to launch the satellite Yubileiny with four various inertioids. One of them is called Gravitsapa and considered as a perpetual motion machine. (Although, due to the principle of relativity of motion, any intertioid is equivalent of the perpetual motion мацчине ).

Several researchers had indicated that the activity of the "Maximov institute" is fraud , but the huge funds are trashed for the development of inertioids and up to year 2011, no sanctions with respect to this institute (nor to its director) seem to be applied by the Russian state authorities.
