Because the chassis/frame is used for the return path.
The single wire in a dynamo lamp is typically used to connect the lamp to the output of the dynamo, which generates electricity from the rotating movement of the wind turbine's blades. The lamp can be illuminated when electricity is produced by the dynamo, providing a source of light powered by the turbine's energy generation.
I'm guessing that you're talking about a bicycle here... They can get by with only one wire, as the steel frame and fork of the bicycle is used for the return path.
The dynamo lamp windmill likely has only one wire because it operates on a simple circuit design where the rotation of the windmill generates electrical current that flows through the single wire to power the lamp. The lamp itself completes the circuit by connecting to the ground or another reference point.

A generator converts mechanical energy into electrical energy by rotating a coil wire through a magnetic field. This process induces a current in the wire due to the electromagnetic induction principle.
A bike dynamo generator works by using the movement of the bike wheel to spin a magnet inside a coil of wire. This spinning magnet creates an electric current in the wire, which is then converted into usable electricity to power lights or other devices on the bike.
A dynamo is a machine that converts mechanical energy into electrical energy. It typically consists of a coil of wire rotating in a magnetic field to generate electricity. Dynamo is also used to refer to a person with a lot of energy and drive.
A dynamo is an electric generator. The basic principle is that, when a wire (or any conductor, for that matter) moves through a magnetic field, a voltage is is induced across the wire. This will cause current to flow.
The wire on a lamp cord that is known as the hot wire is typically the black wire.
A device that changes mechanical energy to electrical energy by rotating a coil of wire through a magnetic field is called a generator or an electric generator. The movement of the coil in the magnetic field induces an electric current to flow through the wire, producing electrical energy. This is the basic principle behind how most power plants generate electricity.
Yes, it is possible to convert the rotational motion of a bicycle wheel into electrical energy using a device called a dynamo. A dynamo is a small generator that contains magnets and a coil of wire. When the bicycle wheel turns, it spins the dynamo, generating electricity that can be used to power lights or charge batteries.
By attaching a fan in the dynamo and rotating the fan and connecting one end of wire in the dynamo and another end in a bulb which helps in glowing of bulb by using the power of dynamo.
