If Zari wants some help, Hunk will be investigating the power source too and is definitely a prominent figure in the kitchen already. He has mechanical/tech knowledge that could probably be put to use. Meaning Zari wouldn't have to explain everything she needs him to do.

So, even if Zari doesn't seek him out, if he comes across her working on it at any point he'd probably offer?

Just, if you're interested (I'm following all the links of the battery/electricty threads and it led me here).
