impac<strong>to</strong>rs and drills. The turbine drives an AC genera<strong>to</strong>r 35 designed <strong>to</strong> supply approximately five kilowatts of<br />

household current at 60 Hz and 110 volts. The turbine is turned on by means of the valve 32 controlled by an/off<br />

switch 36. The speed of the turbine 33 is determined by the pressure of the air accumulated in the turbine tank<br />

30. The pressure is moni<strong>to</strong>red by sensor 27 connected <strong>to</strong> the turbine feed tank 30 by pipe 26. Sensor 27<br />

contains a set of high and low limits. When the turbine feed tank pressure falls below the low limit, valve 25 is<br />

opened through control line 28. When the pressure in the turbine feed tank 30 reaches the high limit, the valve 25<br />

is closed. The high and low limit of sensors 27 are not fixed but subject <strong>to</strong> minor variations in response <strong>to</strong> the<br />

speed of the turbine 33.<br />

The speed of the turbine 33 and of the genera<strong>to</strong>r 35 is moni<strong>to</strong>red by speed sensor 34. The output of the speed<br />

sensor 34 is inversely proportional <strong>to</strong> the speed of the turbine 33. The speed sensor signal 29 is fed <strong>to</strong> sensor 27.<br />

If the output frequency of the genera<strong>to</strong>r 35 deviates from the required 60 Hz, the high and low limits of the sensor<br />

27 are either increased or decreased. If the speed of the genera<strong>to</strong>r is slowed down by an increase in the load<br />

current, the high and low limits of sensor 27 are raised in order <strong>to</strong> raise the pressure in turbine feed tank 30. The<br />

turbine 33 will respond <strong>to</strong> the pressure change by increasing its rotational speed. The output of the genera<strong>to</strong>r 35 is<br />

made available for use through lines 38 and 40 controlled by a switch 37.<br />

The pressure in the holding tank 10 may be boosted from two external sources. First, compressed air may be<br />

introduced through inlet 11. Second, the AC mo<strong>to</strong>r 21 may be connected <strong>to</strong> an external source of electrical<br />

energy through lines 39 and 40 controlled by switch 37. The external electrical source may also be applied <strong>to</strong> a<br />

battery charger 22 which supplies the series of batteries 23. In an alternate version of the preferred embodiment,<br />

it is suggested that an AC/DC converter 41 be used <strong>to</strong> drive the DC mo<strong>to</strong>r 16 from the external electrical supply.<br />

In such a case, the AC mo<strong>to</strong>r 23 and the third compressor 19 are not necessary.<br />

The power plant just described is primarily designed <strong>to</strong> be installed on board a camping trailer. This power plant<br />

will accumulate wind (“aeolian”) energy during the periods when the wind is blowing or the trailer is in motion. The<br />

energy is s<strong>to</strong>red in two forms. First, it is s<strong>to</strong>red in the form of compressed air in the holding tank 10. Second, it is<br />

s<strong>to</strong>red in the form of DC current in the series of batteries 23. Both s<strong>to</strong>rage media are ecologically clean.<br />

Furthermore, the electrical system can boost the power of the compressed air system during periods of heavy<br />

power drain or long use. For added convenience, the system can be refuelled from an external source of<br />

electrical energy such as a household outlet or from an external source of compressed air such as those found in<br />

service stations for use by vehicle drivers. It should be noted also that this power plant is versatile in that it can be<br />

driven not only from the movement of fluids such as air or water, but also from the movement of the vehicle. In the<br />

later case, the shaft 3 would be coupled directly <strong>to</strong> the wheel of the vehicle.<br />
