Windows for producing electricity from solar energy

A system for producing electricity from solar energy, the system comprising:

• a window for installing on a building such that solar radiation impinges thereon, said window includes a windowpane having a first portion and a second portion, each one of said first and second portions includes a first pan facing outside the building and a second pan facing inside the building defining therebetween an inner space,
• wherein the inner space of said first portion is configured to allow sunlight impinging on the first pan of said first portion to be transferred to the building through the inner space of said first portion, and wherein the inner space of said second portion is filled with a thermo liquid, such that solar radiation directly impinging on the first pan of said second portion reaches the inner space of said second portion;
• a heat-receiving element disposed inside the inner space of said second portion and being immersed inside said thermo liquid, such that solar radiation impinging on the first pan of said second portion is converted to heat by said heat receiving element, wherein said thermo liquid is configured to retain heat when no solar radiation is available;
• gas line thermally coupled to said heat receiving element with a heat transferring member said gas line having a liquid gas being configured to evaporate by the heat generated by said heat receiving element and to increase thereby pressure in said gas line;
• a turbine having a rotor configured to convert rotating motion to electricity, said turbine being configured to receive evaporated gas from said gas line and said evaporated gas is configured to rotate said rotor.
