I have a noble idea in the field of renewable energy, and
you can design a
* Small hydro-mechanical design
* Solar powered device that produced electricity
* Small windmill that generates power
You have other lots of options, and you can design
* An industry emitting polluted black water. You can add black dye in a pot inside the factory area to resemble the near water.
* A chimney emitting the high amount of dark, dusty air. You can produce bad air inside the chimney by lighting an aggarbatti.
