DESCRIPTION OF A PREFERRED EMBODIMENT
In the illustrated embodiment there is a generating tank 10 fed with water from a reservoir tank 11 through a float valve 12 to keep the water level in the tank 10 substantially constant. When the apparatus is used in a motor vehicle, the tank 11 can take the place of the conventional fuel tank of the vehicle with a pump 14 in the line 15 to pump more water into the tank 10 when the position of the float 12 indicates that this is required. Water is consumed as hydrogen is generated, and so the tank 11 has to be periodically refilled. The generating tank 10 is in communication with an air cooled heat exchanger 16, which may take the same form as a conventional motor car radiator.

The generating tank 10 is surmounted by a collecting vessel 17 from which hydrogen is drawn through a restricted orifice 18 of an internal combustion engine. Inside the tank 10 there is a drum 19 driven by any suitable means to rotate at a constant speed. The drum 19 is made of aluminium. A depending flange 20 provides a water seal to the top left hand corner of the tank 10, so that that corner is not in gas communication with the vessel 17.

A coil 21 of aluminium wire 22 is fed through a push-pull unit 23 of the kind used to feed welding wire to argon arc welding devices. The unit 23 is arranged to feed the wire against the surface of the drum 19 and to traverse the wire along the length of the drum on a bar 24. The wire passes along an insulating sleeve 25 which enters the tank 10 through a suitable wiper seal.

In the vessel 17 there is a pressure sensor 26 connected to a control unit 27. When the pressure sensor senses a pressure above a predetermined value, it signals the control unit 27 which in turn stops the unit 23 so that wire is no longer fed towards the drum 19. When the pressure drops again, feeding is resumed.

In use, the coil 21 is connected to the high tension side of two ignition coils or transformers 30 and 33. These transformers have primary windings 31 and 34 and secondary, high tension windings 32 and 35. A capacitor 36 is connected across the high tension connections. The terminals 28 and 29 are connected to a conventional vehicle battery.

At the point of contact between the end of the wire 22 and the drum 19 an electrical discharge takes place. As a result the adjacent metal surfaces are heated to high temperature, the protective oxide film which naturally forms on exposed aluminium surfaces is disrupted, and the exposed aluminium surfaces react with the water. In fact the electrochemical situation at the interface is such that the wire 22 is consumed with the following reaction taking place.

2Al + 3H2O ---> Al2O3 + 3H2

As a result, hydrogen bubbles from the contact point while the aluminium oxide collects as a white powder in the base of the tank 10. A grid 37 in the bottom of the tank allows the powder to pass through, and then keeps the powder substantially free from currents in the tank 10. The hydrogen passes through the vessel 17 and the orifice 18 to the carburettor of an internal combustion engine.

There may be a tendency for bubbles of hydrogen to adhere to the surface of the drum 19 which rotates in the direction indicated by the arrow 38. To prevent this happening a wiper blade 39 can be located in the position shown in Figure 1, so as to separate any adhering bubbles from the drum surface.

Alternatively, a wiper blade 40 may be arranged on the opposite side of the drum. In this case a small volume of hydrogen gas may collect beneath this blade, and it may be possible to pivot the blade 40, thus releasing this pocket of hydrogen in order to facilitate start-up of an engine fuelled by the hydrogen.

It may be possible to use salt water in the tank 10, rather than fresh water.

The drum 19 preferably rotates at a speed between 400 and 700 rpm, but the rotation may be as slow as 50 rpm.
During operations the temperature of the water in the tank 10 may rise as high as 95°C, although it is likely that a unit mounted in a moving vehicle, for example, will be able to maintain the water at a lower temperature.

A unit substantially as shown in the drawings has been used to drive a 500cc motor cycle engine. The wire 22 had a diameter of 1.6 mm and was of commercial purity (98%~Al). The unit produced over 1000 cc of hydrogen a minute, with an aluminium wire consumption rate of 140 to 180 cm per minute. The rate of deposition of aluminium oxide was about 4 kilograms per 500 kilometres travelled.

Conventional modifications were made to the carburettor to enable the engine to run on a mixture of hydrogen and air.

The wire 22 carries a voltage of about 18000 volts with a current of about 1 amp.

The invention may equally be used to power stationary industrial engines, as well as motor vehicle engines.

07.11.2007 14:26 (Korvenkulkija) Uskokaa ny! Tarvitaan Loimijoen vettä tehtaan alajuoksulta ennen vuotta 1975! Saatto siinä kyllä olla dieseliäkin.
27.08.2008 10:42 (Diffo) Kokeiltu ja toimii, ohjeessa vaan pari "kirjoitusvirhettä"
16.12.2008 14:47 (The Truth) Autoilija: Tälläisia koneita ei kannateta valtiovallan toimesta, koska he eivät voisi verottaa vesikoneiden käytöstä, ainakaan yhtä tehokkaasti kuin bensakoneiden. Sitäpaitsi kaikki tietävät, ettei Amerikan öljy-yhtiöille v*****lla.
