Had problems though. First was moving parts. You can not expect a system to last outside with any in them. Budget for the whole affair is tight, large repairs undo the whole endeavour .
Second is crops riping at different speeds below.
Finally practicality of the frame for farming machines . Meaning the dimensions need to adapt to pre-existing machines. And ideally remain upright even if one post gets hit.
Finally honesty regarding erosion ..corn is one of the more erosion prone crops and then having water dumped on specific areas concentrated creates channels fast. So the idea does not work with no crops or erosion crops in rainy areas. There is a reason there is grass below most solar fields.
One good aspect they didn't push is that this is ideal for electro farming. We have hyper effective electric moisture traps now and electro nitrogen fixing- combine that and this can remove one need for driving trucks through.
In all other aspects i see this limited to orchards.
