COMPRESSED AIR ENGINE
THE WORLD’S BEST BATTERY.
The MDI technology is able to power any kind of transport.
And also to produce electricity outside of the usual power
networks – for example distributed decentralised energy, on
or off grid, and remote micro grids.
THE AIR IS EVERYWHERE.
This vehicle power or electricity storage and generation systems use compressed air instead of legacy chemical materials, rare earth extraction, manufacture, and eventual disposal. These are huge considerations for the future.
When utilising the compressed air, the expansion of the air restores the energy and produces fresh air & distilled water.
The MDI reversible high-tech engines compress ambient air in approved tanks of various capacities at a pressure of 248 bars.
The expansion of this stored energy in the form of movement is what enables the replacement of all heat engines and cover any type of application: vehicles or to store and re-use electric energy.
The versatility of air means that optionally (called mode 2 or dual mode) a lower temperature external burner can be used to triple the volume of the same quantum of air via heating it. Unlike hybrid vehicles using two systems (internal combustion and battery), the MDI dual mode is a single system. It is hence a very efficient use of the fuel, much cleaner, and ideally suited to use of renewable fuels, for example bio fuels.

OUTER SHELL - LIGHT AND TOUGH
MDI choses to build light vehicles (much lighter than both traditional or electric vehicles with identical capacity). This process includes using “composite” materials, until now the preserve of very high-end vehicles produced on a small scale. It is a process of assembling several components, possessing exceptional bonding strength. In addition the construction process integrates into the body many functions, saving space and weight.
The chassis is formed out of one single piece and designed so that every part of its shape serves a purpose. The result of this integration of functions is a considerably lighter structure, the use of fewer materials, a surprising gain of space, a much tougher structure than in that of a traditional assembly, and incomparable sound insulation.

THE WORLD’S BEST BATTERY. THE AIR IS EVERYWHERE.
Air does not hold intrinsic energy, but when compressed it’s like stretching a spring in reverse:
That can then be – relaxed on demand.
COMPRESSED AIR TANKS (BATTERIES)
One of the strengths of this principle lies in the fact that once this energy is stored it does not deteriorate and remains available.
This is not the case of an electric battery, which loses its power of load over time, as well as its ability to recharge.
The use of tanks as a storage mechanism is completely innovative in the energy storage and electricity industry. For example in the Australian key research entity the CSIRO batteries are defined as chemical. The battery comparison and benchmarking project we are told only allows for chemical batteries.
The MDI storage and generation units are being designed to span a huge range of distributed power storage electricity generation. Compressed air storage has also entered the large-scale utility centralised compressed air energy storage (CAES). With the new MDI achievements in the level of air efficiency usage, the path is open for air to find its rightful place in the climate revolution.
Customers will be able to fill their vehicle’s air tank using a high pressure compressed air station in 2 minutes. Or charge them at home from a simple electrical outlet 10, 16 or 32 amps in 10 to 11 hours, 7 hours or 3 hours 30 min (respectively) or in town on the networks of electric charging stations. Refilling will be a core area of focus for both MDI developments and AFG commercialisation.
