Elec Eng Tech Project Ideas

Ok so I am trying to come up with an idea for my technical Report project for school.

I am at a loss as what I should do. Someone is doing a solar power thing, another is doing wind power, etc. All kinda lame.

I am thinking I should work with PLCs and design some sort of process.

Any help, bros?

Well I just don't want to do some generic shit like everyone else. Oh well, will probably so something on green energy. That seems to be the thing nowadays. I wanted to do a portable vaporizer, but the prof will just think i am a huge stoner.
