Here's a rough of a petition I will be holding when deemed well-written.

Gravel-making improvement.

We, Citizens of Egypt, think our current way of making gravel is tedious and inefficient, be it through the use of a sledgehammer or explosives.

Thus, we turn ourselves to our researchers and suggest they come up with a new technology, Stone Crushing, that would allow us to build and operate a Stone Crusher.

This building would be composed of (with suggested materials):

• a solid base for stability (concrete and cut stones),
• a very sturdy (with upgradable holding size) hopper made of an enduring metal or alloy (sheetings, bars, bolts and straps),
• a towering structure above the hopper to hold the crusher itself (bars, boards, bolts)
• a crusher, basically a sturdy, metalic container (sheetings, straps), filled with heavy filling (cut stone or lead)
• a lifting mecanism of pulleys and wires/cables to lift the crusher, lock it in place and release it down for crushing (pulleys, wires/cables and gears),
• gearboxe(s) to ease the lifting.

The suggested operation would be to :

• Lift the crusher to a certain height, based on Strength (lifting distance) and Endurance (lifting frequency), the lifting mecanism taking care of not letting the crusher fall,
• Empty the hopper of all but one type of stone and/or add more stones. The crusher must be at a minimum height for this.
• Release the crusher, smashing the stones and producing smaller stones and gravel, in a similar way to hammering stones.
• Note: If the stones are mixed, only one type of stone, the biggest available, will be crushed.

- Repeat.
