Could space weather be behind some claims of 'over unity'?

Reading recently about space weather, I read about the disruption that Auroral events caused in old telegraph systems. In some systems, and interesting event occurred, where some systems were able to work without power.

Some telegraph lines however, seem to have been of the appropriate length and orientation which allowed a current (geomagnetically induced current) to be induced in them

This made me wonder. These events involved electrical/magnetic events, and many of the people working on 'over unity' type devices are working in this area. However one of the main problems with claims of over unity, is the claimants are unable to reproduce them consistently.

My idea is that perhaps these systems they are working on are effected by or artifacts of space weather, and this is why they are unpredictable and unreliable.

My science education only went to high school, so I hope this idea isn't just completely stupid, what do people think?
