An absorber system solves problems of known absorber systems for use in solar fields in that the absorber tube is suspended on a rail below an absorber cover. The design also makes it possible to move measuring and cleaning robots and the like along the absorber tube more and allows the absorber tube and the secondary reflector to be jointly suspended, whereby an exact mutual alignment between the two components is enabled.

Disclosed is a device with a heat exchanger having a first flow through which a first gaseous heat transfer medium passes and a second flow through which a second gaseous heat transfer medium passes. Upstream of the first flow, there is a combustion chamber, which optionally extends into the first flow. Two feed lines are attached to the first flow, of which the first feed line is connected to a thermal solar installation and the second feed line is connected to a source for a combustible gas-air mixture or for a non-combustible gas, in particular an oxygen-containing gas, such as air.

A method for moving an end effector based on receipt of sunlight, the end effector divided into a first and second upper quadrant located above a Y-axis that corresponds to a solar azimuth and a first and second lower quadrant located below the Y-axis, the first upper and first lower quadrant located on a first side of an X-axis that corresponds to a solar angle and the second upper and second lower quadrant located on a second side of the X-axis, determining a vertical difference between an average of the illuminance received in first and second upper quadrants and an average of the illuminance received in first and second lower quadrants, determining a lateral difference between an average of the illuminance received in the first upper quadrant and the first lower quadrant and an average of the illuminance received in the second upper quadrant and the second lower quadrant, moving end effector along the X-axis in response to the vertical difference being greater than a vertical tolerance; and moving the end effector along the Y-axis in response to the lateral difference being greater than a lateral tolerance.

Shade house for casting an adjustable shadow over a surface, the shade house including: at least one frame extending in a longitudinal direction; a first set of photovoltaic panels mounted on the frame substantially orthogonally to a same orientation axis; a second set of opaque panels, for preference photovoltaic, mounted on the frame and movable in longitudinal translation relative to the frame at least between an open configuration, in which the panels are at least partially superposed over the panels in a view along the orientation axis, and a closed configuration, in which the panels at least partially extend beyond the panels in a view along the orientation axis; and an actuation system configured to actuate the second set at least from the open configuration to the closed configuration, and vice versa, the actuation system including pulleys mounted on the frame.

A method and a kit for building a protective structure, the method and the kit including supplying a carrying structure, including a plurality of parallel carrying rails; supplying a group of panels, the panels being able to be engaged on and slide on the carrying rails; and transferring the panels from the storage position to a final position bearing on the carrying rails, by transferring at least one of the panels from the storage position to an insertion position on the carrying rails; using a transfer device lifting the at least one panel upward; placing the transferred panels one after the other bearing on the carrying rails; and moving the transferred panels along the carrying rails.

A device for utilizing a surface, such as the surface of a floor, outside wall or roof, for a variable function, including a first functional element with an active surface area the size of at least a part of the surface, at least one second functional element with an active surface area the size of at least a part of the surface, and a rotatable carrier for varying, on at least a part of the surface, the functional element with which the surface is utilized. A method for utilizing a surface for a variable function is also shown.
