“Ok, I have some questions. How do I charge these combines when they are 3 counties away from the shop in the middle of a cornfield, in the middle of nowhere? How do I run them 24 hours a day for 10 or 12 days straight when the harvest is ready, and the weather is coming in? How do I get a 50,000+ lb. combine that takes up the width of an entire road back to the shop 20 miles away when the battery goes dead?”
Simple. Pre-position big diesel generators out in the middle of nowhere, and have fuel trucks deliver as needed. He might need 3 or 4 battery powered harvesters to replace the old diesel harvester, but all he has to do is drive the harvester with the dead battery up to the generator, hook it up, and then take a freshly-charged harvester back out to the field.
Got any estimate on the cost of doing that and how much it would add to food prices?
