Hi all, I am an EE senior in college and am taking a senior design course this semester before I graduate. It involves either choosing to undertake an educational project that one of the class professors suggests or using one of our own ideas. The course lasts a single semester and we are in groups of five students. Since this class is for Electrical and Computer engineering students, our project needs to include some aspect related to our major, but the end use of what we create can be in any field. My group got the list of projects proposed by the two professors in our class and while some were interesting, none just seemed to fit with what we were looking for. The group I am in has several people with power backgrounds so we would prefer to do something related to renewable energy if possible. So far we have tossed around a few ideas like piezoelectricity (using force/pressure or sound to create electricity), a bicycle generator (this idea seems overused to me, but would consider it if we could offer something unique that is not already out there), Portable Water-wheel Generator (think small portable windmill turned upside down in a river), or a windbelt (). These were a few ideas we discussed but do not have to make any final decisions until Tuesday. I figured I would ask the technically-minded fellows here at Physics Forums if they have any additional project that would be appropriate.
