Technical Synopsis
Hypothetical Application Example

KinergyPower system is a site-specific design, therefore the amount of electricity produced is contingent upon the specific issues involved with each site. KinergyPower has developed an energy calculator that estimates the amount of electricity produced based on these varying criteria :

Number of Pistons Piston Stroke Weight of Typical Vehicle Number of Vehicles

The number of activation points varies by site. For example, on level installations the number of activation points, (and consequently the length of the mat) does not exceed the braking distance of the moving vehicle. When used on a downgrade or incline, longer mats can be installed.  When used in a KinerBump (ie., speedbump ) application, the number of activation points is limited by the length and size of the speedbump.

The stroke of the pistons is based on the anticipated vehicle size and most importantly its wheel circumference. For larger vehicles, the stroke can be optimized upwards of 12 centimeters.  As always, the greater the stroke the more efficient the KinergyPower system.
 

The piston’s diameter and resulting surface area is calculated based on vehicle weight and system pressure requirements. A typical KinergyPower system’s hydraulic pressure is based on 550 bar which allows sufficient pressure to support most commercial hydraulic motor generators. Assuming  that all of the vehicle’s weight would cross on a single axle, a 36,000 kilogram truck would require each piston to provide approximately 65.5 cm2 surface area or a diameter of about 9cm. In reality, piston design would spread that weight across the average number of axles expected along with the average anticipated vehicle weight. Using the example above, a transfer truck has five axles and in order to displace the same amount of hydraulic fluid at pressure, the resulting piston surface would only need to be 13 cm2 or about 4 cm in diameter. 

Stroke and piston surface area can be used to calculate fluid displacement for each piston. In this case, each depression of the piston displaces about 157 cm2 or milliliters. Multiplied across the entire mat containing of say 2,000 activation points, each vehicle will displace 1,570 liters. If 700 trucks per day traversed this configuration, the hydraulic system should move in excess of 1,100,000 liters per day. This equates to an average of 763 liters per minute available at pressure to operate the hydraulic motor/generator.  (To use 2,000 activation points, it would have to be a downgrade application where length of the mat doesn’t tax the moving vehicle of its energy. Assuming 4 activation points per meter for transport truck applications, the overall length of the mat is 500 meters).

This example uses this conservative hydraulic capacity estimate to select an appropriate hydraulic motor/generator. Bosch Rexroth AG provides a line of hydraulic motor/generators. This example selects an appropriate unit from the technical data sheet information available at: www.boschrexroth.com 

The motor selected for this example is the Axial Piston Variable Motor Series 6. The specific combination most suited for this scenario is the A6VM – 250. Its basic operating flow requirement is 675 l/min max. provided at 350 bar. This criteria is well within the operating range of the hydraulic system outlined above. Speed and pressure controllers are detailed for this combination in the technical data sheet noted above. This motor is combined with a generator that provides a 394 kW capacity or a daily output of about 9,400 kW hours or 3.5 gigawatts annually. Electricity generation in this example validates the numbers produced with the Kinergy calculator.

The KinergyPower system is flexible to a large degree but some limitations must be considered. It is incumbent on KinergyPowerUSA  to consider each site individually to determine the applicability and efficacy of  the system to its performance expectations. For example, the system may be considered best suited for heavy vehicle traffic that is at least somewhat spread out over the course of the day but by adjusting system parameters, the system could support lighter and more intermittent traffic. Another intuitive example may suggest traffic should stop and progress slowly over the mat to maximize the piston stroke. Though vehicles traveling at greater speeds may make the effective piston stroke shorter, additional mat length may in turn compensate. Conversely, the travel dynamic of the mat lends itself to reduce a vehicles speed beneficial to ingress points of major highway travel centers and rest stops. The system must consider the minimum number of vehicles per day, the average weight per vehicle, an appropriate piston stroke, sufficient piston size, intermittent traffic patterns, the need for continuous power, peak power demands and other similar site specific factors in order to tailor a final design to meet the need. 
 
Break-through technologies are highly scrutinized and generally compared to current convention. The concept and general math behind  KinergyPower’s  technology is clear and plausible in spite of current convention and other generally accepted examples of renewable energy sources. As actual field applications of this technology are implemented, the ability to enhance the design for a reproducible commercial unit capable of providing continuous, reliable electricity upwards of 1-2 Megawatts capacity is a reality.
