The idea of a two-stage mechanical oscillator is concuering the world! Replicating the two-stage mechanical oscillator with a hand water pump has become a global phenomenon.
There is, also, a supstantial growth in scientific research of a two-stage mechanical oscillator at the universities and enthusiasts all over the world. Aside from numerous researchers from USA and EU, the research and mass studies have been intensified in India. Numerous scientific research studies on two-stage mechanical oscillator have been published on several Indian universities. Among them is the world famous University of Nagpur.
New two-stage oscillator scientific research papers published in India
A lot of students choose to do a research study in superefficiency of a two-stage mechanical oscillator and one of those studies can be read on the following link:

Likeways, the two-stage mechanical oscillator as a sperefficient mechanism has found it’s way to the international media thanks to numerous enthusiast researchers. The following video contains a TV show on a two-stage mechanical oscillator replicas constructed in a school in India as part of a science project.
Aside from that, youtube shows an increase in video clips of enthusiasts constructing their own two-stage mechanical oscillator with a hand water-pump, and these are just some of them coming from India.
