My father in law is a mobile combine harvester engineer and was telling me about a client who grows Malt 10 hours drive North of Stockholm. The planting season is Late May early June, The Snow goes around the second week of May and is back some time in October. But he plants and harvests along with his neighbors several thousand acres most years ( Last Year the Snow beat the Harvest window.) The point being there is 22 hrs of Sunlight June July August September. This made me think about the Solar energy implications in a linked system Nothern and southern hemispheres. Obviously its an interesting example of how our pre disposed notions of what is possible can be challenged?
