Description

AN OXYHYDROGEN GAS FUELLED POWER SYSTEM AND A CONTROL SYSTEM AND METHOD FOR OPERATING THE SAME

The present invention is directed towards oxyhydrogen (HHO) gas fuelled power systems, systems for generating HHO gas, and in particular systems for utilizing HHO gas for electricity generation incorporated at a system level in a building to provide independent or semi-independent electricity networks. The present invention is also directed towards systems for controlling the production of HHO gas.

HHO cells generate HHO gas, a mixture of hydrogen (H₂) and oxygen (O₂) gases (typically with the ratio 2 parts Hydrogen for every 1 part Oxygen) by the electrolysis of water. The HHO gas generated has previously been used as an additive for combustion engines. It would be desirable to provide other applications for the HHO gas such as in domestic power generating networks. It would be further desirable to improve the operation and control of the HHO cells and the HHO gas generating systems so as to provide for more reliable generation of HHO gas and electricity, and prevent damage to the HHO cells.

It is an object of the present invention to obviate or mitigate the problems of limited applications for HHO gas, and inefficient, unreliable and potentially damaging generation of HHO gas by HHO cells.

Accordingly, the present invention provides an oxyhydrogen (HHO) gas fuelled power system comprising: an electric generator adaptable to generate electricity using HHO gas; and a control system adaptable to selectively activate the electric generator. Advantageously, the present invention is able to selectively use HHO gas to generate electricity for the powering of appliances, such as domestic appliances, industrial appliances or agricultural appliances. The present invention can achieve an operational independence from a mains power grid, which is especially beneficial in remote and/or inaccessible areas.

Ideally, the HHO gas fuelled power system further comprising a HHO gas source adaptable to supply HHO gas to the electric generator.

Preferably, the HHO gas fuelled power system further comprising at least one HHO cell for generating HHO gas which is preferably storable in the HHO gas source. The HHO cell is adaptable to generate HHO gas using known methods, such as via electrolysis of water into its constituent parts. The HHO cell is powered to generate HHO gas by a main power source, such as mains electricity or a stand-alone power source. Advantageously, the present invention enables the at least one HHO cell to produce HHO gas from a main power source. The HHO gas can be stored and used later, such as when the main power source is unavailable, to enable the electric generator to generate electricity.

Ideally, the main power source and the electric generator being selectively connectable to a load, such as an appliance.

Preferably, the control system having a load switched mode, in the load switched mode the control system being adaptable for selectively activating the electric generator based on the load. Ideally, the load switched mode being activated/deactivated based on a user input.

Preferably, in the load switched mode, the control system being adaptable to switch between the electric generator and the main power source based on the load.

Preferably, in the load switched mode, the control system being adaptable to activate the electric generator based on the load current being at or about a predetermined value. Advantageously, the load switched mode allows the electric generator to be used for heavy duty power consumption based on the needs of the load. The electric generator can supplement the power supplied by the main power grid or replace it while HHO gas fuel is available for powering the electric generator.

Preferably, in the load switched mode, the control system being adaptable for isolating the HHO gas fuelled power system from the main power source in response to the load current being at or about a predetermined current value. Advantageously, this enables the HHO gas fuelled power system to be isolated from the main power source to thereby achieve operational independence.

Preferably, in the backup generator mode the control system activates the electric generator in response to the input power received from the main power source falling below a predetermined power value.

Ideally, the predetermined power value is stored or permanently stored in the control system.

Advantageously, the backup generator mode enables the present invention to operate as backup generator when the main power source is unavailable or unreliable. In particular, when the main power source is operating, the HHO cell can draw power from the main power source to generate HHO gas for storage. When power or current provided by the main power source falls below a predetermined value, the control system can activate the electric generator to generate electricity using the stored HHO gas. The present invention will help provide a constant supply of electricity to appliances, even when the main power source is unreliable.

Ideally, the main power source comprising an AC mains grid.

The generation of power by the renewable power source is intermittent and dependent on environmental factors (e.g. cloud coverage, wind levels, and the tides). The HHO gas fuelled power systems is adaptable to take over some or all of the load for electricity generation in certain situations, such as when the power generated by the renewable power source falls below a certain value, and therefore the HHO gas fuelled power system is able to ensure that a constant generation of electric power is provided.

The invention will now be described with reference to the accompanying drawing which shows by way of example only one embodiment of an apparatus in accordance with the invention.

In the drawings, there is shown a oxyhydrogen (HHO) gas fuelled power system indicated generally by the reference numeral 1 for generating HHO gas using electricity and/or for using the generated HHO gas for storage and for powering appliances 7. Figure 1 shows a HHO gas fuelled power system 1 comprising a control system 2, at least one HHO cell 3, a HHO gas source 4, and an electric generator 5 to generate electricity using the HHO gas. The HHO gas fuelled power system 1 is connected to a main power source 6 and a load 7. The control system 2 selectively activates the electric generator 5. For simplicity, Figure 1 only shows the control system 2 in direct connection with the at least one HHO cell 3 and the main power source 6. However, the control system 2 is operatively connected to the HHO gas source 4 and the electric generator 5 and other elements/devices not shown in Figure 1. Further details of some of these other elements/devices are discussed in greater detail below. The electric generator 5 can have any known construction for utilizing HHO gas for the generation of electricity such as via combustion of the HHO gas.

The control system 2 enables the selective activation of the electric generator 5. Based on the operation of the control system 2, the electric generator 5 can be activated to power appliances 7, such as domestic, industrial or agricultural appliances. The operation of the electric generator 5 can achieve a degree of independence from the mains power grid 6 as it is reliant on HHO gas for fuel rather than mains electricity, and is thus ideally suited for remote and/or inaccessible areas where the main power source 6 is unreliable.

The electric generator 5 receives HHO gas fuel from the HHO gas source 4 which is operatively connected to the electric generator 5 via a gas feed line. In some embodiments, the at least one HHO cell 3 is provided for generating HHO gas by using electrolysis to separate water into HHO gas. The at least one HHO cell 3 is operatively connected to the HHO gas source 4 such that the HHO gas can be stored in the HHO gas source 4 for use by the electric generator 5. The at least one HHO cell 3 requires power to operate, and this can be provided by the main power source 6.

As further shown in Figure 1, the electric generator 5 and the main power source 6 are operatively connected to the load 7. The load 7 can include at least one electrical appliance 7, such as a domestic, industrial or agricultural appliance. The electric generator 5 and the main power source 6 can both power the load 7. In addition to the load 7, the HHO gas fuelled power system 1 can also be connected to one or more gas fed appliances (not shown) which use HHO gas as a fuel source, such as ovens and boilers. The system 1 comprises a gas feed line connecting the HHO cell 3 and/or the HHO gas source 4 to the at least one gas fed appliance. In typical arrangements, the gas fed appliances comprise flashback arrestors for preventing a flame igniting back down the gas feed line, but the present invention is not limited to this specific arrangement.

In some embodiments, the control system 2 has a load switched mode where the control system 2 selectively activates the electric generator 5 based on the load 7. For example, the control system 2 can be programmed to disconnect the HHO gas fuelled power system 1 from the main power source 6 based on the load 7, such as when the load current is at or about a predetermined value. Advantageously, this enables the electric generator 5 to be used for heavy duty power consumption based on the needs of the load 7. The electric generator 5 can supplement the power supplied by the main power grid 6 or replace it while HHO gas fuel is available. In the load switched mode, the control system 2 isolates the HHO gas fuelled power system 1 from the main power source 6 in response to the load current being at or about a predetermined current value. The predetermined current value is stored/permanently stored in the control system 2. The load switched mode can be activated/deactivated by a user.

In some embodiments, the control system 2 has a reconnect mode where the control system 2 reconnects the HHO gas fuelled power system 1 to the main power source 6 based on the output of the electric generator 5, such as when the output of the electric generator 5 falls below a predetermined output value. The predetermined output value is stored or permanently stored in the control system 2 and can be set by the user. The reconnect mode can also be activated/deactivated by a user.

In some embodiments, the control system 2 has a backup generator mode which can be activated/deactivated by a user. The backup generator mode enables the control system 2 to selectively activate the electric generator 5 based on the input power received from the main power source 6. This can be in response to the input power falling below a predetermined power value. This enables the HHO gas fuelled power system 1 to operate as a backup generator when the main power source 6 is unavailable or unreliable. When the main power source 6 is operating, the at least one HHO cell 3 draws power from the main power source 6 to generate HHO gas for storage. When power or current provided by the main power source 6 falls below a predetermined value, the control system 2 activates the electric generator 5 to generate electricity using the stored HHO gas. As such, in the backup generator mode the system 1 can provide a constant supply of electricity to appliances, even when the main power source 6 is unreliable. As in other modes, the predetermined power value can be stored or permanently stored in the control system 2.

In some expected arrangements, the main power source 6 is the AC mains grid. However, in particular advantageous embodiments the main power source 6 is independent from the AC mains grid, and is a renewable power source such as solar, wind, or tidal power. The generation of power by the renewable power source is intermittent and dependent on environmental factors (e.g. cloud coverage, wind levels, and the tides). When the renewable power source is available, the system 1 utilises the renewable power source to generate the HHO gas. When the power generated by the renewable power source falls below a certain value, the HHO gas fuelled power system 1 takes over some or all of the load for electricity generation. Therefore the HHO gas fuelled power system 1 is able to ensure that a constant generation of electric power is provided.

As can appreciated, the HHO gas fuelled power system 1 can comprise none, some, or all of the modes referred to above.

Figure 2 provides a more detailed overview of the control system 2. The control system 2 comprises a cell control device 20 and a cell power device 21. The cell control device 20 and cell power device 21 have an integral construction, e.g. by having overlapping or shared circuitry. Although equally, the cell control device 20 and cell power device 21 can be separate. The present invention is not limited to either embodiment. The cell control device 20 supplies a control signal to the cell power device 21, where the control signal represents the level of power to be supplied to the at least one HHO cell 3. The cell power device 21 supplies power to the at least one HHO cell 3 based on the control signal. The cell power device 21 further comprises at least one measurement device 22. The cell power device 21 provides feedback to the cell control device 20 based on the at least one measurement device 22.

The control system 2 detects the starting/stopping of the electric generator 5, such as by using a tachometer to measure the speed of rotation of the electric generator 5, or by using a current sensor such as a Hall effect current sensor to measure the current drawn by the electric generator 5. The control system 2 will compare the measured current or rotational speed to a known threshold value which is pre-stored in the control system 2, if the measured current or rotational speed has exceeded the threshold value, then the control system 2 will consider that the electric generator 5 has started. In some arrangements, the control system 2 will send a start command to the electric generator 5, and detect whether the electric generator 5 has started. If not, the control system 2 will resend the start command. This process will repeat until it has been detected that the electric generator 5 has started.

The control system 2 further comprises a transformer (not shown), such as an isolation transformer or a 1:1 isolation transformer to isolate the HHO cell 3 from the main power source. The control system 2 further comprises a rectifier which is not expressly shown in the figures. The rectifier receives an AC input from the isolation transformer and generates a DC output. The rectifier comprises a bridge rectifier. Further still, the control system 2 comprises a communication device 23 such as an RS232 serial communication device for communication with external hardware.

Figure 3 outlines an embodiment where the at least one HHO cell 3 comprises at least two HHO cells 3a, 3b. The control system 2 has a cell control device 20, communication device 23, a first cell power device 21a comprising a first measurement device 22a, and a second cell power device 21b comprising a second measurement device 22b. The first cell power device 21a powers the first HHO cell 3a and the second cell power device 21b powers the second HHO cell 3b. The first cell power device 21a and the second cell power 21b can separately and/or independently supply power to the first HHO cell 3a and the second HHO cell 3b.

Figure 4 provides further detail of the cell control device 20 according to one embodiment. The cell control device 20 comprises a microcontroller 40, a display device 41, adjustment device 42, analogue controller 43, speed sensing device 44, starter motor 45, engine ignition device 50, gas valve 49, HHO flow control device 48, pump 46, pump control device 47, water level sensor 51, pressure sensing device 52, and gas leak sensing device 53. Not all of the above devices are required in the system 1, and further devices to those expressly listed above are also within the scope and spirit of the present invention.

Display device 41 can be, for example, an LCD or TFT display 41 although other display technologies can be used as appropriate. The display device 41 displays information related to the system 1. This includes the running time of the HHO cell 3; information related to the at least one HHO cell 3 such as power, voltage, current, and/or a pre-set percentage power value associated with the at least one HHO cell 3; information related to the HHO gas generated, such as the gas pressure, and an indication of whether there is a gas leakage.; and information related to the electric generator 5, such as the rotating speed of the electric generator 5.

Speed sensing device 44 determines the rotational speed of the electric generator 5 and can be a Revolutions per Minute (RPM) meter 44 operating by infrared pulses and/or the Hall Effect. The control system 2 receives a signal from the speed sensing device 44 indicative of the speed at which the electric generator 5 is rotating. The control system 2 determines whether the electric generator 5 is in a starting mode or a running mode based on the received signal, and in particular whether the signal indicates that the electric generator 5 is rotating at a speed in excess of the cranking speed of the electric generator 5. The starter motor 45 is for starting the electric generator 5. The control system 2 engages the starter motor 45 and disengages the starter motor 45 upon determining that the rotating speed of the electric generator 5 has exceeded the cranking speed.

Engine ignition device 50 is for turning the ignition of electric generator 5 on/off. The control system 2 controls the engine ignition device 50 based on the determined state of the electric generator 5.

Gas valve 49 is for selectively directing the HHO gas feed produced by the HHO cell 3 to at least one gas fed appliance. The gas valve 49 can be a solenoid gas valve, and the control system 2 selectively activates the gas valve 49.

HHO flow control device 48 is for controlling the flow of HHO gas to the electric generator 5.

Pump 46 is for pumping water to the at least one HHO cell 3.

Pump control device 47 is for maintaining the level of water in the at least one HHO cell 3 at a constant level. Water level sensor 51 is for detecting whether the water falls below a pre-set low value or rises above a pre-set high value. The pump control device 47 activates the pump 46 based on the water level sensor 51 detecting that the water level falls below the pre-set low value and deactivates the pump 46 based on the water level sensor 51 detecting that the water level rises above the pre-set high value.

Pressure sensing device 52 is for determining the pressure in the HHO cell 3. If the pressure sensing device 52 determines that the pressure has fallen below a pre-set value, the control system 2 powers the at least one HHO cell 3 to generate HHO gas.

Gas leak sensing device 53 senses whether there is an HHO gas leak in the system 1. The control system 2 switches of the system 1 upon detecting the gas leak.

The electric generator 5 comprises an oil sensing device (not shown) for detecting whether the oil pressure falls below a pre-set value. The control system 2 receives a signal from the oil sensing device when the pressure falls below the pre-set value and switches off the electric generator 5.

Figure 5 provides detail of the cell power device 21 according to one embodiment. The cell power device 21 comprises a power switching device 71, current sensing device 72, voltage sensing device 73, input power sensing device 74, AC voltage sensing device 75, switch 76, temperature sensing device 77, and cooling fan 78. The power switching device 71, current sensing device 72 and AC voltage sensing device 75 are discussed in greater detail below.

The input power sensing device 74 measures the current supplied by the main power source 6.The control system 2 can use this information to calculate the overall power used on an hourly, daily, weekly and/or monthly cycle allowing the system 1 to calculate the cost of power used within these periods.

The switch 76 selectively connects/disconnects the HHO cell 3 and/or control system 2 from the main power source 6. The switch 76 can be a relay 76. The switch 76 is controlled by a signal received from the cell control device 20.

The control system 2 activates and/or varies the speed of the cooling fan 78 based on the temperature sensed by the temperature sensing device 77.

The operation of the control system 2 according to some or all of the above embodiments will be discussed below.

The control system 2 provides a cell start mode which increases the power supplied to the at least one HHO cell 3 from an initial power level to a maximum power level. This provides a soft start procedure which can gradually increase the power supplied to the at least one HHO cell 3. This prevents full power being applied to the HHO cell 3 immediately causing a large power surge, and thereby potentially damaging the HHO cell 3. The cell start mode increases the current supplied to the at least one HHO cell 3 form an initial current value to a maximum current value. The initial current value is 0 Amps, and is increased to the maximum current maximum current value in increments such as digital increments from 0-255.

The maximum power level is predefined and can be stored in the control system 2 such as in the memory of the microcontroller 40. The memory can be EEPROM or any other type of memory as appropriately selected by one skilled in the art. The maximum power level can be set by a user, for example by using at analogue controller 43, such as a PWM analogue controller 43.

The cell start mode increases the power supplied to the at least one HHO cell 3 from the initial power level to the maximum power level over a period of time, and can therefore gradually increase the power level. The period of time is stored or permanently stored in the memory of control system 2, and can be set by user. The period of time is 10 seconds or more, 20 seconds or more, 30 seconds or more, 40 seconds or more, 50 seconds or more, or 60 seconds or more. Of course, other periods of time to those expressly listed above are within the scope of the present invention.

In some embodiments, the cell start mode increases the power supplied to the at least one HHO cell 3 by increasing the magnitude of input power signal supplied to the at least one HHO cell 3. The input power signal can be a PWM signal.

When the at least HHO cell 3 comprises at least two HHO cells 3a, 3b, as shown in Figure 3, the cell start mode increases the power supplied to the first HHO cell 3a from an initial first HHO cell power level to a maximum first HHO cell power level, and increases the power supplied to the second HHO cell 3b from an initial second HHO cell power level to a maximum second HHO cell power level. The cell start mode separately and/or independently increases the power supplied to the first HHO cell 3a and the second HHO cell 3b. This enables the cell start mode to increase power supplied to the first and second HHO cells 3a, 3b separately and/or independently, thereby allowing each HHO cell 3a, 3b to be controlled based on, for example, their different properties. The cell start mode increases the power supplied to the first one of the at least two HHO cells 3a from the initial first HHO cell power level to a maximum first HHO cell power level over a first period of time. The cell start mode also increases the power supplied to the second one of the HHO cells 3b from the initial second HHO cell power level to a maximum second HHO cell power level over a second period of time. The first and second period of time are the same, or alternatively different from one another. The control system 2 can comprise a first analogue controller 43a associated with the first HHO cell 3a and a second analogue controller 43b associated with the second HHO cell 3b.

In separate embodiments or additionally to the embodiments outlined above, the control system 2 has a cell run mode for adaptively controlling the production of HHO gas by the at least one HHO cell 3. The control system 2 adaptively changes how much HHO gas is being produced by the at least one HHO cell 3, such as by increasing, decreasing or maintaining the HHO gas production at a constant level. This can be in response to, for example, a change in the demand of appliances using the HHO gas or in response to changes in a main power grid powering the HHO cell 3. This provides a system which is adaptive to ensure a steady rate of HHO gas production and that can also increase/decrease HHO gas production based on demand.

The control system 2 adaptively controls the production of HHO gas by the at least one HHO cell 3 by adaptively controlling the input power supplied to the at least one HHO cell 3. This can be based on one or more parameters, which in turn can be representative of operating conditions of the at least one HHO cell 3. The control system 2 operates by providing a control signal for controlling the input power supplied to the at least one HHO cell 3. The control signal is an adjusted version of the previous control signal used for controlling the input power supplied to the at least one HHO cell 3. As such, the control system 2 utilises feedback to provide adaptive control of the control signal used to control the power supplied to the at least one HHO cell 3. The previous control signals is stored by the control system 2, such as in the memory of the control system 2.

The control system 2 can operate by adjusting the previous control signal based on or more parameters to generate the adjusted control signal using the adjustment device 42. The control signal can be a Pulse Width Modulation (PWM) Signal, and the control system 2 can modulate the PWM signal based on the one or more parameters. The adjustment device 42 is a potentiometer controller, digital potentiometer controller, or a PWM digital potentiometer controller. When the at least one HHO cell 3 comprises at least two HHO cells 3a, 3b, the adjustment device 42 comprises a first adjustment device 42a and a second adjustment device 42b. The first adjustment device 42a is for adjusting the control signal for the first HHO cell 3a and the second adjustment device 42b is for adjusting the control signal for the second HHO cell 3b.

The power switching device 71 of the control system 2 controls the supply of input power to the at least one HHO cell 3. The power switching device 71 controls when power is supplied to the at least one HHO cell 3. This controls how much electrolysis occurs in the HHO cell 3 and allows for more or less HHO gas to be created either on demand or to charge a pressurised cylinder that stores the HHO gas for later use. The power switching device 71 receives the control signal and switches on/off based on the received control signal. When the power switching device 71 is switched on, a maximum power is supplied to the at least one HHO cell 3 and when the power switching device 71 is switched off, a minimum or no power is supplied to the at least one HHO cell 3. The power switching device 71 is a digital power switching device 71 such as, for example, a power MOSFET or IGBT.

When the at least one HHO cell 3 comprises at least two HHO cells 3a, 3b, the control system 2 adaptively controls the first HHO cell 3a and separately and/or independently adaptively controls the second HHO cell 3b. The control system 2 adaptively controls the first HHO cell 3a based on one or more parameters associated with the first HHO cell 3a, and adaptively controls the second HHO cell 3b based on one or more parameters associated with the second HHO cell 3b. The control signal comprises a first control signal associated with the first HHO cell 3a and a second control signal associated with the second HHO cell 3b. The power switching device 71 comprises a first power switching device 71a associated with the first HHO cell 3a and a second power switching device 71b associated with the second HHO cell 3b, the first power switching device 71a receives the first control signal and the second power switching device 71b receives the second control signal. The control system 2 can independently control the operation of a plurality of HHO cells 3a,3b based on parameters which are unique to the individual HHO 3a,3b cells thereby improving the efficiency of the individual HHO cells 3a,3b.

The measurement device 22 of the control system 2 measures at least one property of the HHO cell 3.The at least one measured property is indicative of the one or more parameters. The control system 2 determines an adjustment amount based on the at least one measured property, and adjusts the control system 2 based on the adjustment amount. The control system 2 can store the previous control signal used for controlling the input power supplied to the at least one HHO cell 3, and adjust the previous control signal based on the adjustment amount to generate an adjusted control signal for controlling the input power supplied to the at least one HHO cell 3. The measurement device 22 comprises a measurement sensor to generate an analogue signal. The control system 2 converts the analogue signal into a digital measurement signal and determine the adjustment amount based on the digital measurement signal. In some arrangements of the present invention, the measurement device 22 comprises a current sensing device 72. The current sensing device 72 comprises a current sensor such as a Hall Effect current sensor. The current sensing device 72 measures the current drawn up by the at least one HHO cell 3. This allows the system to automatically read how much Amps or KVA current is being drawn via the HHO cells 3 and modulate how much gas needs to be generated by adjusting the control signal (e.g. increasing or decreasing the PWM signalling). In alternative arrangements or in addition the arrangement outlined above, the measurement device 22 comprises a voltage sensing device 73, 75 the voltage sensing device 73, 75 comprises a voltage sensor 73,75. The voltage sensing device 73 measures the voltage across the at least one HHO cell 3. This allows the control system 2 to automatically adjust HHO gas production as well as switch the HHO cell 3 on/off by measuring the voltage the HHO cell 3 is using. The voltage sensing device 75 measures the level of AC voltage available to the system 1. This allows the control system 2 to determine how much AC voltage is available, allowing the control system 2 to use this information to adjust the power to the HHO cells 3 accordingly to produce the required amount of Hydrogen gas.

During use, the control system 2 controls the HHO gas fuelled power system 1 to selectively activate the electric generator 5 based on the load 7, such as the load current being at or about a predetermined value. The selective activation can comprise switching between the electric generator 5 and the main power source 6 based on the load 7. The control system 2 is further able to isolate the HHO gas fuelled power system 1 from the main power source 6 in response to the load current being at or about a predetermined current value. The control system 2 is further able to connect/reconnect the HHO gas fuelled power system 1 to the main power source 6 based on the output of the electric generator 5, such as based on the output of the electric generator 5 falling below a predetermined output value. The control system 2 is further able to selectively activate the electric generator 5 based on the input power received from the main power source 6. The selectively activating can comprise activating the electric generator 5 in response to the input power received from the main power source 6 falling below a predetermined power value.
