How do you pump out water from a lake up to 8 ft above adjacent agricultural Lands without power as Local Law does not allow windmills and Solar gadgets?

Pumping out water from a lake up to 8 ft above adjacent agricultural lands without power, and with local laws prohibiting the use of windmills and solar gadgets, can be achieved through an Archimedes screw. It involves employing a cylindrical tube wrapped around a helical surface to lift water. Here's how you can implement it:

1. Materials and Tools:

- Archimedes screw (fabricated or locally crafted from metal or plastic)

- Strong rope or cable

- Pulley or block and tackle system (for lifting the Archimedes screw)

- Support structure (e.g., tripod, framework)

- Long handle or winch (for rotating the screw)

2. Setup:

- Place the Archimedes screw in the lake, with the lower end submerged in the water and the upper end extending above the 8 ft height you want to achieve.

- Attach a rope or cable to the upper end of the Archimedes screw and run it through a pulley or block and tackle system set up on the shore or a stable support structure.

- Ensure that the rope is long enough to allow the screw to rotate freely and reach the desired height.

- Install the support structure to hold the pulley system and the Archimedes screw in place.

3. Operation:

- To pump water, rotate the Archimedes screw using the long handle or winch.

- As the screw rotates, water will be scooped up by the helical surface and lifted upward through the tube due to the principle of positive displacement.

- The water will continuously flow out from the upper end of the screw, discharging into the desired location above the agricultural lands.

The Archimedes screw operates based on simple mechanics, requiring no external power source. It utilizes the turning motion to create a continuous flow of water, without relying on wind or solar energy. By manually rotating the screw, you can efficiently pump water from the lake to the desired elevation without violating local laws.
