Figure 8 is a circuit diagram of an eighth embodiment of apparatus according to the invention which is a modification of the seventh embodiment; and Figure 9 is a circuit diagram of a ninth embodiment of apparatus according to the invention which is a further modification of the seventh embodiment. Referring to the drawings and initially to Figure 1, the first embodiment 10 of apparatus for delivering electromagnetic energy into a solution comprises a 9N mains adapter 11, an oscillator crystal 12, a buffer chip 13 and an antenna 14. A Zener diode 15 allows only 5.1 volts to pass through as the oscillator crystal 12 only requires a supply voltage of 5 volts + 0.1 volts. The oscillator crystal is the main component of the apparatus and in this particular embodiment outputs a radio frequency signal of 20 MHz which is sent through the buffer chip 13 to the antenna 14. Similar components in the other embodiments are given similar numbers as in the first embodiment. The second embodiment 20 is similar to the first embodiment, except that it includes a rechargeable battery 21 as well as the 9V mains adapter 11. Battery 21 acts as a backup power source. It also includes a switch 23 and a light emitting diode (LED) 24 which emits light when the switch 23 is closed and the unit is operating. The third embodiment 30 is similar to the second embodiment 20 but includes a separate LED 35 which is used to indicate that the unit is being powered by a mains adapter. The LED 35 emits a red light to distinguish it from the LED 24 which emits a green light. The fourth embodiment 40 includes a 9N mains adapter power supply 11, an LED 24 for indicating power on and a switch 23 for operating the unit. The fifth embodiment 50 is similar to the first embodiment 10 and includes a power on light LED 24. The sixth embodiment 60 is similar to the second embodiment 20 but includes a mains adapter 61 which gives a 12V DC supply of 700 mA. It has a power supply socket (not shown) which accepts a jack plug from the adapter. The circuit also includes two diodes 63 and 64 which only allow current to flow in the direction which it is pointed. Diode 63 enables the battery 21 to drive the main circuit when the mains adapter 61 is not charging or plugged into the apparatus. Diode 63 also protects the battery from being improperly charged when adapter 61 is plugged in and operating the circuit. The seventh embodiment 70 shown in Figure 7 includes the majority of the components used in the first six embodiments, namely a rechargeable battery 21, a crystal oscillator 12, a buffer chip 13, an antenna 14, a switch 23, an LED 24, an LED 35, a mains adapter 61, 3 diodes 63, 63(a) and a diode 64. Diode 63(a) only allows LED 35 to illuminate when the mains adapter 61 is plugged into the apparatus. The eighth embodiment 80 shown in Figure 8 is similar to the seventh embodiment 70 except that it has an output modified by filter circuit 85 to reduce secondary and tertiary harmonics so as to reduce interference with other wavelengths and keep the output frequency to a constant value which in the eighth embodiment in the range 27.225 MHz to 27.255 MHz The filter circuit 85 includes three capacitors 86 and three impedances 87. The ninth embodiment 90 shown in Figure 9 is also similar to the seventh embodiment 70 except that it has a generator 95 for generating a DC supply from the flow of water which is used to recharge battery 21. In relation to all of the above embodiments, the antenna 14 is an elongate wire which in the particular embodiments used is 0.889 m in length which approximates to 1/16 of the particular wavelength of the RF signal generated by the crystal oscillator 12. In a modification (not shown) the antenna has a brass ball on the end of it with a cover. The apparatus according to the invention has numerous applications; it can be used to treat water used to irrigate plants and flowers. The antenna can extend along the inside of a hosepipe used to supply water to the plants. It can be demonstrated that it enhances plant growth by achieving higher yields of fruit, vegetables, plants, flowers, shrubs, trees and other plant life. The apparatus can also be used to treat water used in domestic applications, it helps prevent or eliminate scaling in kettles, coffee making machines, taps, faucets and showerheads. It will of course be understand that the invention is not limited to the specific details described herein, which are given by way of example only and that various modifications and alterations may be made without departing from the scope of the invention as defined in the appended claims.
