"a hundred miles square" means 100 x 100 miles, 10,000 square miles. The linked article makes this clear. At $250 per square meter, 10,000 square miles of panels would come to $6.4 trillion. I think we should be heading in this direction anyway. But it's not so small, it's not so cheap, it will take time. No surprise; the system we need to replace is not small or cheap, and it took time, too. |
