A Gravity turbine is a device to harness gravitational energy.
In simple words gravity turbine is a device which converts downward motion of any entity (in this case water) due to gravity in to rotary motion which powers alternator to generate electricity.
This was invented by Nagendra Singh and this arrangement was filed for patent on 27th August2010 in India at Mumbai patent office.
Gravity Turbine consists of …
1. Two buckets
2. Water flush system and
3. Solar Water Pump.
In the beginning one bucket is at the top and another is at the bottom. The mechanical flush system senses the bucket which is at top and commands flush systems to fill the bucket from water reserve at the top. Once the top bucket is filled with water it starts descending down due to gravity powering corresponding shaft to rotate and the empty second bucket attached to another shaft start ascending up with corresponding shaft rotation. Once the filled descending down bucket reaches bottom water is flushed out and bucket gets emptied. Simultaneously, the second ascending bucket reaches top. The water which is flushed out at the bottom is collected at bottom and recycled to top water reserve using solar water pump. At the top mechanical sensor again sense the presence of second ascending bucket at top and flush out water to fill the same. Thus second bucket becomes heavy and first bucket becomes lighter. Due to gravity this time second bucket starts descending down. Consequently, first lighter bucket ascends up as it becomes lighter with corresponding shafts rotation.
The up and down motion of bucket is transfer to the third shafts which in turn rotates in one single direction only. The special arrangement is made in such a way that third shaft rotates in single direction only although first shaft and second shaft can rotates in both direction. Third shaft is attached to Dynamo or Alternators which on rotation generate energy.
