Pneumatic cylinders are stronger per volume but vacuum can be immensely strong, regardless of volume. So if a cylinder is made very tiny but geared up massively then the same pneumatic air tank could give hugely more energy for its volume and structural integrity--right? Some day, building, filling, and dropping cylinders of space vacuum to Earth could therefore be the only truly infinite source of renewable energy. Perhaps vacuum cylinders could even be used to blow back captured air (a vacuum jet) to slow descending space vehicles... Does this seem reasonable?
