Engineering/Energy Questions?

[JC0133]

So I am helping or trying to help my younger cousin with a school project. He is like in the 5th grade, and goes to some fancy school. Anyway he is task with creating like an energy backpack. Basically he is supposed to use an object to charge up solar energy and and then something to transfer that energy into a device(any device, cell phone, etc)? So like a moving charger that uses the sun.

I am more into software can anybody help me out with this? Mostly ideas and materials on how to do it?

Also are there any like Electrical Engineering or Engineering forums that would be a good place where I can ask questions like this?

Thanks any help is appreciated.

Cross that with something like this, and you could probably get USB output power too.
