Electric trailer with drill brake?

i found this pic,and i cant figure out what the drill is for.

i though it could be for chainging gears on the left wheel or a brake system, but i dont see a derailleur or calipers for a brake.
it has a battery,motor some sort of controller


Any ideas?

I think it's for a turbo boost.

Maybe he's using the drill as a generator?
