Science Buddies: "Ask an Expert"

I have been working on
EcoCity - Alternate Sources of Energy & Sewage Treatment.

I have Figured out how i can make Solar Panel for, Solar plant & a Windmill to work.

Solar Panel - Using Glass & painiting it with glass colour & then making it glow with Some kinda light under it.

Windmill - Motor

But i Havent Figured out how to show a bit of working in these following-:

• Hydroelectricity Plant
  Sewage Treatment Plant
  Biogas plant

& i had a City Plan but that was very conjusted. Please help me & please teach me electrical works too , to make the project work...

In the City , There would be

• Housing Apartments - Buildings
  Parks
  School
  River
  CNG Refilling Station
  Hydroelectric Plant
  Sewage Treatment Plant
  Biogas Plant
  & any other thing that would suite a city

I will make a model. Not small. Fair Size.
