While reproducibility is an obvious issue, the phenomenon did occur...sometimes. Id say this is more a testament to Mr Huthcisons amateur lab or the lack of an additional variable he wasnt aware of like geomagnetic activity. https://www.drjudywood.com/pdf/HutchisonEffectReport_txt.pdf
I doubt this is the result of manufacturing defect as this person thinks. My theory is the Hutchison Effect (the fracturing of metal due to multiple sources of EM radiation) is causing the severe suspension issues. I believe that Teslas motors are a significant source of the EM radiation contributing to this phenomenon. However, the Hutchison Effect requires multiple sources of EM radiation to combine, one of which is comes from surface EMF during enhanced geomagnetic activity, to cause metal fracturing like what's being seen in Teslas.
