Academician Veljko Milković's two-stage mechanical oscillator is slowly but surely conquering the world. The latest scientific paper we found is the first to include South America in the places where this Milković invention is studied. This thesis comes from Antonio Narino University located in Bogotá, the capital of Colombia.
In this comprehensive thesis, the authors Jhon Alexander Alape Vega and Rodrigo Romero Bernal constructed a manual pendulum water pump with a capacity of 20 lit/h and investigate the results of raising water to a height of 1 meter. The basis for this paper is the problem of drinking water supply in rural areas of Colombia, with the comment that local authorities are not willing to deal with it or have higher priorities when it comes to capital investments. Essentially, a manual water pump with a pendulum is cited as potentially the most economical solution that would make it easier to get drinking water in rural areas.
In the third chapter of this paper, the authors clearly refer to Veljko Milković in a video showing the operation of a two-stage mechanical oscillator, and in the paper itself, a patent application for a pump with a pendulum is shown. Also, based on the videos and calculations presented in the paper, the authors created their oscillator prototype in order to perform measurements and experiments such as raising water to a height of 1 meter.

The application of irrigation technology is very important for the sustainability of farmers. This paper presents a pendulum irrigation model. The designed model attaches to a hand pump for water. The developed system will work without any external energy source, which will ensure maximum profit for farmers.
