A prize-winning invention by Orian Brunavs, a student of the Townsendl High School in Bulawayo Zimbabwe, could help breed chickens aided by the sun's heat. This innovative application of solar power in livestock management includes a solar-heated chicken breeding house. A black concrete collecting slab transfers the solar heat to water pipes embedded in the walls and floor of the breeding house, which in turn heats the insides of the house.

The invention can also be used for other purposes. For instance, it can efficiently heat greenhouses in winter to prevent frost formation (Sun Worla,VoI19,N04).
