Test Results

The Space Power Generator, when tested by Mr. Toby Grotz of Wireless Engineering, produced low voltage ac or dc power at about 2.5 times the mechanical power applied at its shaft. Further improvement since then in the construction of the SPG producing dc power has raised its efficiency to about three times the mechanical power applied.

The next generation SPG will use electrical output for feeding a Faraday motor mounted on the same shaft to achieve self-sustaining operation. Certain specific configurations of magnetic fields from rotating electromagnets and electrical conductors have made it possible to construct an SPG that produces ac power presently in the same range as the SPG producing dc power with an efficiency of about 250 percent. Photograph 1 shows the SPG that produces ac power and Photograph 2 shows Mr. Grotz sitting behind the SPG that produces dc power.

The SPG producing ac power has a specific configuration of rotating magnetic circuits with respect to the conductor producing ac voltage through electromagnetic induction.

Table 1, where test results on the ac SPG are given, shows that the ac electrical power generated in the SPG is 2.5 times the mechanical input applied at its shaft over and above the constant losses due to windage and friction. One conclusion of this advantage is that rotation of the entire magnetic circuit, and the specific path that the load current takes within the magnetized iron core, is responsible for over-unity efficiency in the SPGs. A similar conclusion was drawn on the rotation of the magnetic field where, in an experimental setup when part of the magnetic circuit was fixed with the Earth's reference frame, the efficiency of the SPG decreased. In the ac SPG, the conductor in which the voltage is induced does not form a co-rotating system (as it does in the dc SPG), and yet the machine produces ac power at over-unity efficiency.

No Load Tests

A. The SPG was run at 700 rpm. With electromagnets energized using 18 amps dc current the following was observed:

1. The emf developed = .509 vdc (I)
2. The input current to drive dc drive motor (DM) increased by .3 A dc. This increase in input is attributed to eddy currents due to slight non-uniformity of the magnetic field in the air gap.

B. The machine was run at 1050 rpm with the excitation of the electromagnet kept constant at 18 A dc.

1. The emf developed in the SPG was .762 vdc (II)

From (I) and (II) it is seen that the emf generated at constant excitation is directly proportional to speed.

C. The SPG was run at 2690 rpm.

1. The no load current to the DM was 8.55 amps (III).
2. The no load voltage at the DM was 346.9 vdc (IV)

From (III) and (IV) the no load input of the DM while coupled to the SPG that accounts for windage and friction, at the speed of 2690 rpm = 2966 watts. (V)

Load Tests

D. The machine with shunt connected across the output terminal of the SPG was kept at constant speed of 2690 rpm when the test described in C above was repeated.  The electromagnet was energized at 18 amps dc and the following was observed:

1. Input current to the DM = 15.5. A dc (VI)
2. Voltage at the DM's terminal = 339.9 V dc (VII)
3. The shunt load voltage - 47.25 mV dc (VIII)
   • This circuit includes the output leads and contact resistance of two sets of sliding contacts (copper-graphite brushes)
4. On load input to DM =15.5 x 339.9 = 5268.45 W (IX)

Efficiency

E. EMF of the SPG at 2690 rpm from (I) = (2690 x .509/700) = 1.956 vdc (X)

DC current output from the SPG from (VIII) measured with a calibrated shunt (2000 A = 50 mV) = 47.25 x 2000/50 = 1890 A dc. (XI)

From (X) and (XI), the output of the SPG (total including heat generated in the SPG and load circuit) = 1.956 x 1890 = 3696.8 watts. (XII)

Against 3696.8 watts of output power from the SPG as above, the corresponding rise in DM output from (V) and (IX)  = 5268.45 = 2966 = 2302.45 watts (XIII)

Over and above the windage and friction at any speed, each kW of additional power to the drive motor of efficiency 0.8 (DM's efficiency at this loading), from (XII) and (XIII) will produce, 3696.8/2302.45 x 10/8 = 2 kw of power.

The expression of efficiency of the SPG will be
efficiency = output/(output/2 + losses) (XIV)

Heat Balance

From input to DM on no-load supplied towards windage and frictional heat and power output (I²R) of the SPG, total heat output of the SPG, from (XII) and (V) = 6662.8 watts (XV),

Whereas input on no load to SPG is 5268.45 watts (from (IX)) which shows that 1394.35 watts of additional energy is generated in the SPG.

From (XV) and (IX), the overall energy efficiency = ((6662.8/5268.45) x 100) = 126.6%

India Trip Report
August 2000

Tewari's machine is as usual measuring overunity. 9 KW electrical energy in and 9 KW electrical energy out plus 3 - 4 KW heat out. (I squared R loss across the brushes). Tewari has found a method of reducing the effect of Lenz's law. His next model will be a substantial improvement over the current unit.  The current unit was funded for 3 years by the GE of India, Crompton Greaves Ltd. CGL admitted in an email to me from the a Manager, who is an electrical engineer with a background in motor and generator efficiency measurements, that the SPG was over unity. CGL is not pursuing the invention because they do not see a market for a low voltage high current machine.
