Generating Electricity from Waste Water
This one's especially for California - I have had this idea for years: As the waste water approaches the treatment plant, have it hit by a ring of laser beams. This will create steam which will turn the turbines to make the electricity. What remains will be germ free but good for topsoil, making soccer fields etc...

Reward: Provide a garbage disposal system for Berat, Albania.
