Here you can watch the March 5th replay with Bram Cohen and Gene Hoffman, where they teach the most efficient way to farm large quantities of plotted storage and talk about the impact Chia might have in terms of total electrical capacity used to support all Chia farms.
They field questions and talk about farming rigs and strategies in the fist half of the session. The second half covers macro trends in the storage business and how total Chia Network electrical usage will and will not scale over time.
