Concerning the Commercial Application of The Energy Invention of Mr. Joseph W. Newman
I have recently had the opportunity to visit with Mr. Newman at his workshop and take a close look at a new application of a particular embodiment of his energy invention. I believe that this unit which he demonstrated for me has definite commercial possibilities. I was able to make my own measurements to verify his claims.
Background of The Invention
The energy invention of Mr. Newman may be built so as to be used in several different ways. It may be designed to produce electrical energy with which to recharge batteries and operate other electrical devices, or it may be constructed so as to produce a surplus of mechanical power. When constructed in this manner, the device operates as an extremely efficient electric motor, and requires very little electrical energy to produce substantial mechanical work.
If his invention is considered solely as an electric motor, then it violates well-established engineering design guidelines for building motors. In fact, it would appear that Mr. Newman has rewritten the engineering textbooks on motor design with this device. Engineers well versed in conventional motor design may not at first understand what he has done, nevertheless, they are surprised and delighted at the results, for the power output is far greater than is possible to obtain from conventional electric motors.
In the case described in this paper, Mr. Newman has taken one of his motors and attached it to a circular table saw. The saw is mounted on a hand constructed wooden table, about two feet by two and a half feet across and of convenient working height. This size makes for ready portability and ease of carrying.
The motor (of his own design) is about 5 inches in diameter and about 14 inches in overall length. Since it is bolted down, I cannot tell you the exact weight, but on the basis of his previous motor designs, I would estimate that this particular unit weighs between 15 and 20 pounds.
The power source for the motor is a bank of conventional alkaline "dry" batteries in a series connection. This is the same type of power source which is used for most of Mr. Newman's other motor designs. These batteries are mounted on a wooden shelf which is placed below the motor. The total battery voltage applied to the motor at full operating speed is about 5,500 Volts. This battery voltage is applied to the motor in steps during the start-up period, but this appears to be due to some imperfections in the design of the hand-made commutator. This stepped starting procedure also achieves better battery use.
Construction and Design
This motor is connected to a 6 inch carbide tipped general purpose saw blade through a timing belt speed reduction system. This method was chosen for minimal mechanical energy loss and belt slippage. The speed reduction is single stage, with a drive pulley of about 3/4 inch diameter and a driven pulley about 3 inches in diameter. The belt used is a cogged tooth timing belt about 3/4 inch wide.
This prototype unit uses bronze bushings for bearings in the speed reduction system. As a result, the drive system has quite a bit of friction in the reduction pulley bearings. The belt is also a bit narrow for the power to be transmitted. (I've worked with these belts before, and they are a good choice for this application.) Mr. Newman plans to add ball bearings and a wider belt to improve the efficiency of his prototype.
Operation and Results
The motor drives the saw blade at what I would estimate at about 800 to 1200 RPM. (This is an "eyeball estimate".) The saw can cut a hard pine 1 X 2 board cleanly through in about 2 seconds with little change in RPM. It cuts a 2 X 4 in only a little more time. While running free with no load, the motor draws about 5 watts. When cutting the 1 X 2, the system draws about 25 to 30 watts.

I have had the occasion to work closely with Mr. Newman over the course of the last 8 years, and make tests on various models of his energy invention. This discussion pertains to that version popularly knows as the "saw motor". I had an opportunity to observe and test the device shortly after Mr. Newman assembled the unit, and later, after he had redesigned it for greater efficiency.
The following paper, written after my first observation and testing of his saw motor is included here for background information. A further discussion of the motor in it's present embodiment follows this earlier paper. Although the motor has been redesigned, the same basic facts still are true - the device exhibits extremely high efficiencies as a motor, and has great potential for commercialization.
When you compare this to a regular table saw - or any other type of power-driven saw for that matter, these power consumption figures are quite impressive. This extremely low power requirement means that a power saw being driven by a Newman Motor may easily be operated from a solar panel using a standard storage battery and a transistorized high voltage power inverter. In fact, while I was at his workshop, Mr. Newman demonstrated the saw operating from a high voltage DC power supply running on a transistorized power inverter which was connected to a small "Gel Cell" 12 volt storage battery.
Even allowing for the loss in efficiency to be expected from the power inverter/battery combination, and allowing for twice the power input to the motor to allow cutting thicker and harder materials, this device could easily be used with solar panels and/or storage batteries in areas where there is no commercial electric power available.
I feel that this version of Mr. Newman's invention may be used with any device which requires mechanical power from a motor. It is my belief that this particular embodiment of Mr. Newman's invention has strong commercial applications. Although it will require some research and development to determine the best way to manufacture the device, I feel it should be actively pursued and brought to commercial production as soon as possible.
In the revised form the motor exhibits a power consumption of between 7 and 20 times less than the saber saw motor to perform the same task. Some concern has been raised by outside observers as to whether the saber saw has an oversized motor, and that because of this, the test may be invalid.
It should be noted that tests of the saber saw indicate that using the proper blade as recommended by the manufacturer, the saw is capable of cutting through the 1 X 2 board at the rate demonstrated by Mr. Newman without excessive difficulty. If the motor was actually overpowered, the saber saw should be able to cut through he wood at a much faster rate.
In actual fact, however, the saber saw will "bog down" when an attempt is made to speed up the rate of cut through the wood. In addition, the saber saw motor begins to draw much greater current, and the efficiency decreases. This indicates that the saber saw motor is not overpowered, but instead, it is well matched to the load it has to handle.
In contrast, Newman's motor can be forced to cut the wood even faster than he has demonstrated. When this is done and the increase in motor current is measured, it is found that the slightly increased power used by the motor indicates that the motor is still operating at a very high efficiency. If anything, it is the Newman Motor that is overpowered, and not the saber saw.
