3 years ago, my brother in law in Longview, Texas had a quadruple bypass and a valve replacement. It was done robotically, over the Internet, by a doctor in Rotchester, New York. Who would ever have thunk such a thing 20 years ago.

I reckon that some money could be made by a smart guy that could figure out how to make a “freeze proof” wind turbine. Or maybe a turbine that can spray itself with de icer.

Same for a “high storage” battery made from easily obtainable materials.

There’s a lot of smart folks running around. Somebody will figure it out.
