Wind power installation, generator for generation of electrical power from ambient air, and method for generation of electrical power from ambient air in motiion

A wind power installation for generating electric power from ambient air, with a flow channel, through which the ambient air is conducted by the formation of an air stream, wherein the flow channel comprises an external sleeve forming its boundary and also comprises:

• a first section with an essentially constant cross section, into which the ambient air can be introduced, wherein an air acceleration device is provided in the first section,
• a second tapering section,
• a third section, following the second section, in which third section a rotor is installed, which is set in rotation by the through-flowing air stream and the rotation of which serves to generate electric power,
• a fourth enlarging section, and
• a fifth section, which comprises a second air acceleration device, which serves to discharge the air introduced into the flow channel.

A method for generating electric power from ambient air, preferably ambient air which has been put in motion, which comprises the following steps:

• introducing ambient air into a first section of a flow channel,
• accelerating the air stream by means of an acceleration device, which is installed in the first section of the flow channel,
• further accelerating the air stream in a second tapering section of the flow channel by means of a constriction in the flow channel,
• conducting the air stream through a third section of the flow channel and the driving of a rotor in this section,
• discharging the air stream into a fourth enlarging section of the flow channel,
• renewedly accelerating the air stream in a fifth section of the flow channel, and
• discharging the air stream into the environment, wherein both kinetic energy and heat energy are extracted from the air stream during its passage through the flow channel.
