The Feltenberger Pendulum Pump by Gravitational Energy Corporation, is a commercially available device that is manually operated and uses "gravity-assisted power" (GAP), coupled to a piston pump, capable of pumping and filtering 1,000 gallons of clean drinking water per hour. It is human-powered, with no fuel required, and little fatigue to the operator – like pushing a child on a swing.
It is basically a commercially-available version of Milkovic's secondary oscillation technology.
- "The Feltenberger Pendulum, a unique double reciprocating device (Patent Pending) uses the force of gravity to help provide the power to pump water. We have combined a new power off-take system with a rigid arm pendulum, which makes it much easier to pump water manually than a conventional lever arm pump, which requires a constant push or pull type of action; or a hand crank, with a constant turning action. Due to the nature of the pendulum swinging back and forth, it is far easier to provide a short intermittent push to the pendulum once every arc or every over and back cycle to maintain the pumping process, thereby substantially reducing operator fatigue. In this manner, we have achieved a 'gravity assist' in helping us do work."
Water filtration and reverse osmosis equipment can be added to produce clean drinking water. Other attachments will be available soon that can be coupled to the Feltenberger Pendulum that will provide for deep water pumping, well drilling, desalinization and small scale electricity generation. 
On June 2, 2010, Gravitational Energy Corporation donated their first pre-production prototype machine for use in Haiti, where it has been providing potable water for 4,000 people daily on just three hours of manual pumping.  Running continuously, such a pump could provide enough drinking water for 40,000 people.
This device is recommended for communities seeking to be prepared for extreme emergencies, such as grid power going down for long periods of time. One of the systems advantages is that it runs quietly, especially compared to a fuel-engine based pumping system.
In addition to the pump application, the company anticipates building large scale Feltenberger Pendulum machines for the purpose of generating commercial grade electricity. The target of these machines is to reduce fuel consumption by about 50 percent.

There are a few things thing’s I would like to point out. We changed the capacity to read up to 1000 gph. We are planning a larger hand powered pump but not sure of its out put yet. We are also working on two smaller versions.
We gave Milkovic stock in our company for what he is doing to help mankind and have two associates that help him as well. Our system is quite a bit different. We can go 360 and the pump has 4 Pressure Volume settings. We are patenting the pump and it is 92% efficient a centrifugal pump at the same Pressure Volume is about 35%.
We just showed the pump to the US Military and they are very interested in the pump and the technology.
Return To Gravity Assisted Power
- Gravitational Energy Corporation of Cuyahoga Falls, Ohio explains the Feltenberger Pendulum's patented technology using Gravity Assisted Power. Its mechanical advantage leverages gravity to do work using less fuel. Tests involving this 18,000 pound pendulum prototype suggest it can generate commercial grade electricity more efficiently than current fossil fuel power plants. (YouTube; February 02, 2011)

Gravity Assisted Power [Overview]
- Gravitational Energy Corporation, Located in Cuyahoga Falls, Ohio, presents new technology for pumping water with Gravity Assisted Power. The pump is hand operated, uses no fuel or electricity, is very easy to operate and can produce 1000 gallons of filtered water per hour. The first production model is in Haiti to produce clean filtered water for the people and Hospitals. (YouTube; March 2, 2010)

How it Works
Quoting from http://gravityassistedpower.com/?page_id=9
- "The Feltenberger Pendulum is a unique double-reciprocating pendulum. [See videos.] As the pendulum rotates, the axle reciprocates in a linear (straight line) manner, causing a pumping action. The amount of water being pumped is determined by the distance that the axle slides in and out of the pump while it rotates. The axle is connected to a piston rod that pushes or pulls the piston in the pump. Water is pumped while the piston moves in both directions during the in and the out strokes. The further the piston moves, the greater the amount of water that is pumped.
- "The distance the piston moves varies based on the mode of operation and the Pressure/Volume (P/V) setting. The pendulum can be pushed in a gentle manner, describing a relatively low over and back succession of arcs. If compared to the face of a clock a good example would be from 4 o’clock to 8 o’clock and back again. This will produce about one half the pumped water that would result from a higher arc of 2 o’clock to 10 o’clock. If the pendulum is rotated 360 degrees or in a continuous spinning manner, it will pump the maximum amount of water for any given P/V setting.
- "There are four different P/V settings that can be selected depending on the desire of the operator. Changing from one setting to another is easy and takes only a few seconds. First, the pendulum must be stationary. Then, on top of the machine, above the Gravity Assisted Power label there is a device, which looks like a black box. Protruding from this device is a selector pin, which can be easily pulled out and removed and then inserted into another position. There are four positions to choose from and they are numbered one through four.
- "The effect of moving the selector pin from one P/V position to another is similar to shifting gears in a car. Position one produces the highest pressure and lowest volume of water. Position four produces the highest volume of water at the lowest pressure. Positions two and three are incremental changes in pressure and volume."
for permanent installation
for portable applications
The technology can also be installed permanently at an existing pumping facility.

The Company was incorporated in July 2007 as a private C type corporation. Mr. Bruce Feltenberger, the Company’s President and CEO, is the inventor of the Feltenberger pendulum technology, which he has assigned to the Company.
Prior to incorporating the Company, Mr. Feltenberger, Mr. Drentlau and Mr. Butrick worked for approximately three years designing, building and testing various prototypes of the Feltenberger pendulum. This unique, double-reciprocating pendulum now demonstrates how to use the force of gravity to help provide the input power to operate various types of machinery.
