I read that last one, on "Telautomatics". He mentions his attempt to interest auto manufacturers in a self-driving car. But he also describes some kind of odd flying machine that doesn't use wings or propellers etc, relying purely on "reactions". What could he have been talking about? Inertial propulsion? Some kind of reaction against electromagnetic fields? There is a great illustration of this thing. Weird. (Incidentally, you could draw a straight line from all those magazine ads to today's YouTube versions)
