Generate electricity w/ hydro-generator from city water used by your home and yard.
Idea Description
Use a generator like the ones used by Wind Turbines to generate electricity as water passes through the pipes from the city water supply to your house. Whenever you water your plants, take a shower, wash dishes, wash laundry, brush your teeth, flush the toilet or use water for any purpose, you will be generating electricity.
What will you do if you win $10,000 for this idea?
Build a prototype and test it.

What about the 2nd law of thermodynamics? If everyone on the system had a generator, wouldn't all the energy used to create the water pressure be used up?
That would probably work, but it would seriously decrease your water pressure.
I've actually thought about this for years! good call, definite up vote for you!
The water pressure shouldn't be a problem if you use the waste water. Well, good idea, but he ratio between effort and generated electricity is not very well.
