It may not be the sleek, light or slim structure that we’ve come to expect from our mobile phones, but it does the job and more importantly… it does it for free. Using spare parts from a telephone and a television set, Petrus has built a handset that uses radio frequencies to place calls anywhere as long as there is signal. The invention also functions off power supplied through a radiator.
According to Namibian publication New Era, it took Petrus two years to develop his invention, which was funded by his unemployed parents, and cost around N$2 000 (R2 000) to produce. The unit also features sockets that enable cellphones to be charged, a light bulb and a fan as well as the capability to watch TV through his box.
