Abstract: A wind turbine comprises a nacelle, a generator and a high voltage transformer which are connected to each other and are located inside the nacelle. The wind turbine is provided with a low voltage power supply source which is located remotely from the high voltage transformer and comprises a low voltage transformer connected between the high voltage transformer and a power grid. The low voltage transformer is connected to the nacelle and provides it with low voltage power.

Abstract: A system (10) and method for the induction of a fluid into the combustion chamber (15) of an internal combustion engine comprising a cylinder head (12) having at least one intake port (14) communicating with at least one combustion chamber (15) via a valve seat (22) disposed about the intake port (14), and at least one intake valve (16) provided with a valve head (20) having a valve face (21) engageable with the valve seat (22). The valve head (20) is connected to an elongate valve stem (18) that is mounted in the cylinder head (12) for controlling the intermittent flow of fluid from the intake port (14) to the combustion chamber (15).
