The document describes a system for generating electricity using rainwater and wind power. Rainwater is collected from rooftops and directed to turbine blades to create rotational motion powering a generator. A wind turbine can also be placed on the rooftop. The system effectively uses renewable resources in rural areas without electricity access, is environmentally friendly, and has lower maintenance costs than solar; purified water from the turbine can also be used domestically.

1. GENERATING POWER BY USING RAIN WATER AND WIND
The basic idea is by collecting rainwa-
ter from rooftop or tin shade and di-
recting water to the turbine blades
where rotary motion is created. This
rotary motion is effective enough to
rotate the armature of a generator
which can produce electricity. Further
a wind turbine can also be placed at
the rooftop by which we can generate
electricity.
In order to do this the rooftop has to be de-
signed such that water can be temporarily
stored and can be made to flow in a particular
direction. The turbine is placed at a consider-
able distance from the rooftop so that the
velocity of the water stream is enough to ro-
tate the turbine. The shaft of the turbine is
directly connected to the armature of a gen-
erator. Due to the rotation of the armature
electricity is generated which can be supplied
tt to a rechargeable battery.
The salient features:
 Effective use in rural areas where electricity is not available.
 Environment friendly
 Cheaper than solar cell and less maintenance cost
 the used water in the turbine can be later puri-
fied, stored and used for domestic purpose.
Due to moderate wind flow the wind turbine ro-
tates which can enable us to generate electricity
in the same manner. It has to be noted that the
output of both generators are applied to the same
battery.
