energetic hurried sandwich white battery by Jack

I'm doing a school project and it's all about how energetic men can power a battery nobody knows if it’s even possible yet, and that’s why our class is on the case. We hurried and tried to figure out if it’s possible but then the bell rang, and It was time for lunch. I had a sandwich while my friend Jake had a packet of crisps. After that we went home and by the time I got home our house was painted white which really didn’t suit it. So, what do you think? Can energetic people power batteries?
