Overview
The joint project, initiated in 2005 and still in the experimental stage, developed a prototype

Carbon dioxide is a chemical compound with the chemical formula . It is made up of molecules that each have one carbon atom covalent bond, covalently double bonded to two oxygen atoms. It is found in a gas state at room temperature and at norma ...
()-free engine in 2006 that ran successfully without the need for
fossil fuels. The chemical reaction between magnesium (in a powder form) and water at room temperature produces high-energy
steam
Steam is water vapor, often mixed with air or an aerosol of liquid water droplets. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Saturated or superheated steam is inv ...

Hydrogen is a chemical element; it has chemical symbol, symbol H and atomic number 1. It is the lightest and abundance of the chemical elements, most abundant chemical element in the universe, constituting about 75% of all baryon, normal matter ...
. The hydrogen is burned at the same time to produce additional high-energy steam. These two steam sources
power the engine. The energy cycle produces no carbon dioxide or other harmful
emissions. The only by-products of this reaction are water and
magnesium oxide
Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2− ions ...
. The magnesium (a common metallic element) is separated from the oxygen through a solar-powered laser process (the development of which is already well advanced) and is reused over and over again as fuel.

dimension
In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus, a line has a dimension of one (1D) because only one coo ...

and 13.5 cm in height), the engine can generate a heat output of several tens of
kW from which power is obtained.
The engine is intended for use in
cogeneration, automobiles, ships, and many other areas. A statement in 2006 claimed that further research was planned to achieve
commercialization within the next three years.
No updated timeline has been released.
