(If 1 Kg of lithium ion batteries can hold 0.265kwh and $1 buys 3.6 watt hours)
Farming machinery is probably going to continue to be liquid fuel powered.
Then some of these machines only get used for a few weeks a year.
Some machines only stop when they put fuel in them and when they get trucked down the road to the next field.
They have to run nearly 24 hours a day or the crops rot in the field.

OK. I'm just using a Tesla 85 kwh pack as a reference here. Assuming we could just tie a bunch of Tesla packs together. Check my math for me though.
An 85 kwh pack weighs 540 kg.
1.5 Mwh = 1500 kwh
1500 kwh /85 kwh =17.65 Tesla packs
17.65 x 540 kg =9531 kg.
Current cost of a Tesla pack is $111/kwh. I know that even if we could get them that would not be our cost. But.
$111 x 1500 = $166,500.
See anything wrong with my numbers?
