Clever! In the same vein I have seen sorts of boots with internal
combustion, Russian stuff I think, allowed to run very fast.

Subject: Re: BioDiesel vs Air-Powered Pogo Sticks
My patent: on a pressure-actuated-injector-diesel-powered pogo stick:
3782352 January 1974 in response to
the oil embargo, has been usurped by this more environmentally friendly
model.
I'm not hopping mad either. How many leaps per liter? :-)

"A pneumatic pogo stick is comprised of an elongate cylindrical housing
which forms a cylinder. The housing is formed from a clear polycarbonate
plastic. A top cap is attached to one end of the housing to form the top
of an air chamber. A plastic piston, slidable within the cylinder, forms
the bottom of the air chamber. An elongate shaft is coupled to the bottom
of the piston and is moveable therewith, extending from the distal end of
said housing as the piston moves within the cylinder. A bottom bracket
assembly is attached to the bottom of the housing and a bushing for
maintaining the lateral position of the shaft relative to the housing is
attached to the bottom bracket assembly. The bushing prevents the shaft
from rotating relative to the housing. User foot supports are also
attached to the bottom bracket for supporting the feet of the user and
handle bars are attached to the top cap for grasping with the hands of a
user."
