According to New Era,
(A Namibian Newspaper company) Petrus, who is a learner at Abraham

The young inventor put together parts from a telephone and television
set that according to him, only uses a radio system. It also has a light
bulb, a fan and a socket for its charger, among others.
Although, this is not the only design Petrus has come up with. Last year
he won a gold medal at the NamPower schools’ competition, held at the

teacher said; “When he won last year some judges were of the opinion

According to Vatileni, generally Petrus is an average learner, but he is the best learner in the physical science class.
