"Technobank of  Georgia" has been developing since 1998 some kinds of fuel-less generators wich work on energy of the centrifugal acceleration and vortex.

Similar generators have been created later by other authors completely casually. For example by Tariel Kapanadze in 2001 year  and  Bobby Amarasingam  in 2010. 

  . Therefore parameters of their variants are very ineffective also these designs have many superfluous details. Authors of these analogues cannot explain the reason of occurrence of superfluous energy with authentic theoretical hypotheses. 

Our generators are developed on the basis of the real theory - therefore they have ideal proportions and the minimal weight.

The most compact variant of this generator can be looked on a link:

 You can have a look the theoretical substantiation and drawings of  such engines  in a  File Catalog. This theory is written at such level, that each person who understands elementary concepts of Physics can understand it.

By theoretical analogy alongside with mechanical variants there are already developed electrodynamic and air-hydro-dynamical variants. Only аir-hydro-dynamic and electo-mechanical variants are submitted on this site. Other variants are a trade secret.
