looks like a really good way to make used re bar reusable.

I've seen a lot of scaffolding poles thrown away because they were bent. that machine could actually pay for itself

Must be a lot of people running those things over to need to build a machine to straighten them!

Those poles most generally get pretty bent up when the scaffolding's are removed.
care is taken to erect the things 10 20 30 stories high tieing them to the building going up but when finished the teasr down is not so gentle. a construction site may have close to 50 tons or more of poles and they are often times rented from a scaffold supplier. sometimes the supplier wets them up maintains and removes them but this is an additional fee not many construction companies are willing to pay. They elect instead to pay a huge deposit and damage fee up front then write it off and let the scaffold rental company deal with the carnage

That one going through the machine looks like it has been driven in the ground as a marker. I know someone with a scaffolding company and I'll have to ask him if this would be allowed with our OSH laws! Plus we use all Galvanised or Aluminium 3" pipe here and that stuff only looks about 2" so I thought they might be used as fencing.

T-Post Straightener
Another possibility is to clone a wire straightener, just bigger wheels and bearings.
