Put another way, we could get rid of corn ethanol, switch 30% of the freed-up farmland to solar to generate 100% of US electricity, and use the other 70% of the freed-up land for whatever we want.

Found out today there is a guy walking from Punta Arenas in Chile to Hull, UK. He started in 1998.
He crossed the Bering Strait on foot. 152 miles following shifting ice.
He also crossed the Darien Gap and swam the Caspian Sea in his "Goliath Expedition". 🤯
