The Barra system is a passive solar building technology developed by Horazio Barra in Italy.It uses a collector wall to capture solar radiation in the form of heat. It also uses the thermosiphon effect to distribute the warmed air through channels incorporated into the reinforced concrete floors, warming the floors and hence the building.
Solar powered flashlights can be used in remote locations where it is impossible to find any source of electricity except for solar power. [4] A built-in solar cell array in a hand-held product has a very small capacity.
