I am currently seeking ways to improve my life and decrease living expenses by using chemistry and physics. To be more specific, looking for useful chemicals to aid in cleaning and such and ways to create some extra electricity (i am not afraid of providing mechanical energy because i could use the exercise.  ). I would like any other suggestions on how to make my life easier using science.

Although your question is very broad, it is fun to think about.
There are so many possibilities we could keep this thread going for a long time.
Especially if we include both chemistry and physics.

Some if my initial thoughts were making soap, making bio-diesel, and creating dyes.

Maybe you can get some inspiration from this site
