User blog:Legionwrex/What do Reapers do with the technology they harvest?

I believe it is mentioned that at the end of each cycle, the Reapers strip and Harvest the current cycle's tech and wipe out all traces of their existence, but this leads to a question that has never been answered: What do the Reapers do with the tech that they harvest?

I mean just think about it, after thousands of cycles they have to have billions of empty ancient space-cars and other useless (to them at least) peaces of technology just floating around in Dark Space. So do they use it as a means of recycling (to construct their tech and build new Reapers with) or are they just hoarders?
