POWER GENERATION
This invention can be used to generate power from any fast moving river
without the use of a dam to contain the water. The essence of this patent is
that water is brought by penstock from a suitable spot in a fast flowing
river to a turbine generating system.
Blast a trench in the river bed for approximately 50 feet to accommodate the
penstock. The penstock should be anchored to the bedrock. The penstock should
be approximately 15 % larger diameter for the first approximately 15 feet.
Then tapered to match the other sections. The penstock should have steel rods
inside the entrance to keep out larger animals and a steel screen with
approximately 1 inch opening could keep out fish, etc. on the outside a steel
plate closure. The amount of power generated would be a function of the
volume of water and the head, a difference in elevation between the water
inlet to the penstock and the turbine. The larger penstock, with closure,
should be installed first, with valve outlets on smaller penstocks going to
the turbines. As the water is drawn off it will be easier to guide the
remaining water to the entrance and conventional generating system which could
be installed in the bed or bank of the river. The penstock could follow a
tortuous path after a reasonable start. This invention would eliminate
silting which is a problem with conventional dams.
The following are possible methods of placing additional penstock sections.
If the river is navigable, a barge pulled by a tugboat could be used to
transport the penstock sections. A crane mounted on the barge could place the
sections. To assist alignment three strong magnets could be used. The
penstock could be tap welded and finally completely welded from the inside of
the penstock if space permits. If the river is not navigable a caterpillar
tractor might be used to pull the barge. If this failed, a crane might be
used to transport and place the sections. Finally a helicopter might be
required.
The drawing shows one of many possible layouts.
