HYDROGEN POWERED TOY ROCKET UTILIZING HYDROGEN FROM THE ELECTROLYSIS OF WATER This is a continuation of provisional application 60/353,161 filed January 30, 2002 entitled Toys and Power Driven Equipment Utilizing Hydrogen from the Electrolysis of Water.
BACK GROUND OF THE INVENTION It is well known to use electrolysis to separate water into its hydrogen and oxygen components. However, the designing and building of a reusable toy rocket assemblage using the components of electrolysis has always been believed to be unattainable and uneconomical and thus while desirable has eluded legions of designers and developers.
SUMMARY OF THE INVENTION In accordance with the present invention there has been developed a novel toy system that uses simple and inexpensive sources of power and ignition systems to bring about the electrolysis of water and ignite the hydrogen component and capture the explosive power obtained therefrom to power a toy rocket. The power generated is directed in a simple, and efficient and safe manner. to drive the toy rocket.
Other features and advantages will be apparent from the following drawings and descriptions thereof in which; Fig. 1 is a cross-sectional view of a toy rocket launcher illustrating the condition of the system wherein the power has been turned on and through electrolysis oxygen and hydrogen gases are being produced in the same or separate chambers; Fig. 2 illustrates a selection valve being operated to transfer oxygen to the launch tube over which the toy rocket is disposed; Fig. 3 illustrates a selection valve being operated to transfer hydrogen to the launch tube ; and Fig. 4 illustrates a successful launch of the rocket.
DESCRIPTION OF THE DRAWINGS Referring to Fig. 1 there is illustrated a toy rocket launcher assembly 20 on which a rocket 22 is disposed over a launch tube 24 prior to firing. The rocket has a tubular housing 23 that fits over the launch tube 24 and fins 25 that helps to guide the rocket during flight. In the illustrated embodiment the launcher 20 includes a base 26 on which is mounted a chamber 27 in which hydrogen is generated and a chamber 28 in which oxygen is generated. Both chambers 27 and 28 are filled with water from a suitable source (not shown). The base 26 also includes a battery pack 30 that supplies power through wire 32 to an anode 34 in the water filled oxygen chamber 28 and through wire 36 to cathode 38 in the hydrogen chamber 27. A power switch 39 controls the flow of electricity to the anode 34 and the cathode 38. While separated chambers has been illustrated the anode and the cathode can be located inside a single chamber and if separation is desired the electrodes could be separated by a permeable membrane.
The membrane mesh would allow for constant flow of fluid but the mesh is small enough to keep the hydrogen and oxygen bubbles within their single chamber. Mesh is not necessary when a single chamber is employed. It is further noted that citric acid could be added to accelerate electrolysis.
In Fig. 1 the system is in an intermediate stage wherein the selection valve 40 is in a neutral position and the power switch 39 is turned on to start the electrolysis that functions to provide oxygen gas 29 in chamber 28 and hydrogen gas 31 in chamber 27.
With the selection valve 40 in the neutral position some water is in the launch tube 24 and the rocket 22 surrounds and sits atop the launch tube 24. The selection valve 40 is then moved to the right as shown in Fig. 2 to admit oxygen gas 29 and some water to the launch tube 24 from the chamber 28 and then when selection valve 40 is moved to the left as shown in Fig. 3 to introduce hydrogen gas 31 to the launch tube 24. The hydrogen and oxygen gases under pressure in the launch tube 24 forces the water roughly into the position shown in Fig. 1 except that the iaunch tube is fiiied with an explosive hydrogen and oxygen gas mixture. The arc electrodes 42 are surrounded by the hydrogen and oxygen gases and the piezo igniter 44 generates a spark and the gas mixture explodes with a large force to launch the rocket 22 as shown in Fig. 4. In this position the selection valve 40 has been returned to the neutral position and the chambers 27 and 28 refilled with water. This process can be repeated and provides an endless source of enjoyment for the user.
In another embodiment within the scope of the invention the system would include a single chamber that holds the cathode and anode wherein the oxygen and hydrogen gases are generated through electrolysis. This embodiment would also include a battery pack for the power for the electrolysis and electrodes for ignition. The unit would be operated by a remote control having an on/off and igniter switches.
It is intended to cover by the appended claims all changes and embodiments which fall within the true spirit and scope of the invention.
