Maybe the government could pass a Rural Electrification Act and form a
Rural Electrification Admininstration.
Oh, wait, they did that in 1939 and 1935 respectively.
Since 98% of all farms in the US had electric service by the early 1970's,
the REA was abolished in 1994 and replaced with the Rural Utilities Service.
We're talking 200 kW in a remote field, not 2 kW at a farmhouse which
might even be in a town.

You put your finger on one of the many problems of using electric
powered farm tractors and such. Figure the wire size needed for a
150 hp. tractor, three phase 480 VAC and 2600 feet from the power
source. Somewhere around 165 amps would be about right. Imagine
moving that around in a field or from field to field.
