the thought did occur that in an agricultural context powering machines directly from the grid might not be so daft.
Not so daft. I dimly recall hearing of a fellow with a GE Elec-trac tractor who powered it with a long extension cord. IIRC he had a receptacle in the middle of his yard and he mowed from the middle out, paying out cable as he mowed. Aren't mining vehicles powered from huge drop cables?
I recall a farmer who electrified his tractor, and ran a huge "extension cord" to power it.
Some mines do indeed run vehicles from big "extension cords". I toured on of the big taconite mines in northern Minnesota, and their huge shovels were powered that way. The cord was as big around as your arm!
