1. A system for harnessing energy from wind, said system comprising:
a convergent section, said convergent section comprising an entry and an exit, said entry having an area higher than said exit;
a wind turbine section adjacent to said exit of said convergent section, said wind turbine section comprising at least one wind turbine;
a divergent section adjacent to said wind turbine section, said divergent section comprising an entry and an exit, said entry having an area lower than said exit, wherein at least one of the convergent section and the divergent section comprises side panels extending away from the wind turbine section, characterised in that:
at least two of said side panels are modifiable in use for maximising the amount of energy harnessed within a time interval in accordance with wind direction and/or wind speed;
said wind turbine section comprises a turbine-surrounding structure that at least partially surrounds said at least one wind turbine, wherein said turbine-surrounding structure:
has openings for wind to pass from the convergent section, through the turbine section, and exit to the divergent section;
is rotatable around the at least one wind turbine in use, such that the orientation of the turbine-surrounding structure and its opening are adjustable relative to the side panels; and
comprises two walls separated from each other by the openings, wherein said walls of said turbine-surrounding structure can rotate independently so that the angles and/or sizes of the openings can vary depending on wind conditions in order to optimise system performance.
