1. A fluid stream energy conversion apparatus comprising:
one or more turbines mounted inside a housing and configured to rotate about one or more rotational axes, the turbine including a rotor and a plurality of blades which protrude from an outer surface of the rotor, and a main funnel having front inlet and exhaust openings and configured to collect and compress a fluid stream through the front inlet opening, wherein the fluid stream energy conversion apparatus is configured to direct the fluid stream collected by the main funnel,
wherein an extendable part of the main funnel includes an adjustable inlet surface area means preset in an extended position configured to expand an inlet surface area of the main funnel and configured to reduce the inlet surface area according to predetermined set fluid flow values by retracting the extendable part of the main funnel,
wherein the adjustable inlet surface area means includes panels which fold back by origami technique or slide back or includes a sail of flexible material having a surface and configured to roll back when the pressure of the fluid stream reaches a predetermined setting.
