Hybrid and Closed Cycle Pneumatics
Excellent and informative
technical articles and patents on air cars and stationary pneumatic
power plants that use Hybrid and/or Closed Cycle pneumatic power plants.
Hybrid is a system that uses a gas or diesel engine to run a compressor
and an air engine to run the car. Closed cycle or "return-pipe"
air systems have many advantages; this involves recompressing the
exhaust air into the tank for re-use of the same air.
Reheating Compressed Air
Reheating compressed air to
obtain a unit of power from the air later is several times cheaper than compressing more air from scratch
to achieve the same gain in available energy. A
scientific study giving detailed performance data of air engines like
the ones used to run pneumatic locomotives, using straight compressed
air, reheated compressed air, steam, and a steam-air mixture. High
efficiencies were attained.
Mechanics of Vehicles
How to figure out how much
power you need to run a car under various conditions, air car speed
records, air and steam vs. internal combustion for torque delivery,
tractive power of compressed air locomotives. For a simplification
of the most important parts of this excellent book, see
Compressed Air Power Secrets.
Composite Materials, and Impact Protection
Filament-wound tanks that
weigh a fraction of solid metal tanks, and are much safer. Carbon,
Kevlar, and fiberglass-wound tanks available in many sizes from a
variety of manufacturers. In 1982, I was told by an engineer at one of
these companies that a tank one foot in diameter, ten feet long, and
wound with carbon fiber around a thin aluminum shell to safely hold
15,000 psi would weigh only 100 pounds.
Regenerative Air Car Designs
Heat recovery, using the
energy in high pressure air, regenerative braking, regenerative shock
absorbers, neutralizing wind resistance.
The fluid diode is a shape-forced flow
condition approximating the effect of a mechanical one-way check valve,
without using any moving parts. The first fluid diode was invented
by Tesla, who called it the "valvular conduit." The cascade diode (ABOVE)
is one of the best fluid diodes, using successive stages of stationary
blades to gradually turn the air around so it is many times easier for
the air to go forward than backward. These devices are used in
fluidics, the micro-logic division of pneumatics akin to electronics.
The French Escopette pulsejet, among others, use a similar concept in a valveless pulsejet.
Eskeli's Work-free Heat Pump
Except for his first two
patents, which describe rotary pulsed-jet pumps, all
these patents are talking about machines that manipulate fluid flow to
capture ambient heat and re-store it at a level of energy quality where
it will be usable to fuel the manipulations that make the necessary
energy available. The basic design is a rotor with fluid pathways
and heat exchanger cycles. The self-sustaining aspect hasn't yet
proven itself out to my knowledge, but his premise is applicable to the design of
free range air cars and stationary solar pneumatic power plants. Includes
an article written by Eskeli in the '70s, an article written about him
in 1989, and 31 of his 56 patents.
Fluid Power without Moving Parts
Steam-jet refrigeration, vortex tubes,
heat pipes, fluid diodes, pulsed combustors, and the Coanda effect:
jet-powered hovercraft without fans.
It was General Herman Haupt who suggested the use of jet pumps to induce
additional atmosphere into the compressed air in order to increase an
air car's range between fill-ups. The "thermal compressor" has no
moving parts, but it has plenty of names: jet pump, injector, airmover,
inducer, inspirator, vacuum pump, ejector, pressure exchanger, venturi,
dredge, etc. Info on jet pumps, boiler feeder injectors,
efficiency of jet pumps, steam injector design manual (1890), 80 psi air
injector that puts air into a 60 psi tank, manufacturer info, Coanda
effect air amplifiers, engineering info.
