A method for operating a wind energy installation, in particular for adapting a wind energy installation (10) to given wind conditions, the wind energy installation (10) having a rotor (16), which can be driven by wind, with at least two rotor blades (20), whose respective angles of incidence of the wind can be adjusted by means of at least one adjustment device, and having a generator for converting the mechanical energy of the rotor (16) to electrical energy. During operation of the wind energy installation, parameters are measured with spatial and / or temporal resolution on the side of the wind energy installation (10) facing the wind, said parameters describing the wind conditions in the measurement region, preferably the wind speed and / or the wind direction. The wind parameters are measured at various vertical distances from the ground, namely various heights, and at horizontal distances from the rotor (16), which are selected such that the angles of incidence of the wind on the individual rotor blades (20) can be adapted in response to the measured wind parameters before the wind on which the wind parameters are based, in particular a wind front or a gust of wind, reaches the rotor (16). Values are predicted or calculated, in particular continuously or periodically, from the measured wind parameters—prognosis values—which describe wind conditions occurring in the future at the rotor blades for various heights. The angles of incidence of the wind on the individual rotor blades (20) are adjusted individually and independently of one another, preferably a plurality of times during a complete revolution of a rotor blade, depending on these predicted or calculated prognosis values at the various heights.

A solar thermal powered aircraft powered by heat energy from the sun. A Rankine-Brayton hybrid cycle heat engine is carried by the aircraft body for producing power for a propulsion mechanism, such as a propeller or other mechanism for enabling sustained free flight. The Rankine-Brayton engine has a thermal battery, preferably containing a lithium-hydride and lithium mixture, operably connected to it so that heat is supplied from the thermal battery to a working fluid. A solar concentrator, such as reflective parabolic trough, is movably connected to an optically transparent section of the aircraft body for receiving and concentrating solar energy from within the aircraft. Concentrated solar energy is collected by a heat collection and transport conduit, and heat transported to the thermal battery. A solar tracker includes a heliostat for determining optimal alignment with the sun, and a drive motor actuating the solar concentrator into optimal alignment with the sun based on a determination by the heliostat.
