History is not the story of the past; it is the study of the future. Unless you live on the East Coast, you will NOT have any idea what this is. In the days after whale oil and before diesel, homes on the East Coast had coal furnaces. Coal, by the ton, would be dumped into the basements of the homes through chute doors like this one.  All winter long, residents would shovel coal into a furnace to keep the home warm. Home heating oil tanks made the coal chute doors obsolete. Power grids made the heating oil tanks obsolete and within a decade, solar panels will make the power grid obsolete. Technology is speeding up. In the 1960s, gasoline was cheap and plentiful. Today gasoline is getting so expense electric cars are becoming economic.  The key to success is seeing the future before it becomes the present. That’s why you study history.  [See my books at https://authormasterminds.com/master-of-the-impossible-crime.]
