9.0 Infrastructure Materials, Construction and Maintenance:

9.1Construction Speed and Costs:

The basic concept of the Grid=s physical systems is to construct the System quickly using state-of-the-art materials, however, at a low cost made possible by a unique construction System design.

9.2Grid Columns and Footings, Rail Attachment:

Although Grid support columns (AGrid Columns@) are relatively massive, measuring at least six (6) feet in diameter; they are constructed using common materials such as typical high-strength concrete and reinforcing steel. Atop the Grid Column, situated by a series of shims, is a simple steel AI@ beam which spans the Grid Columns. The I beam is connected to the Grid Columns by standard bolts, much as bridge trusses are attached to abutments. The Grid Rail is completed by the installation of a continual (to the extent possible) titanium or stainless Cap, or in some cases may be completed using a poured fiberglass/epoxy or high-strength plastic surface. The Grid Rail is banked with shims to balance the effects of circumferential force in turns.

9.3Wear on Grid Rail Cap:

As an HPR vehicle=s Thrust Plate passes atop the Cap, over time, it wears down the Cap or upper surface. Wear to the Grid Rail is easily restored by replacing the Cap or sections of the Cap or re-molding the high-strength plastic where used.

9.4Umbilical Cord - Not Buried:

All electrical apparatus required for the propulsion and control of Grid vehicles will be installed via an electrical umbilical cord placed along the lower corridor of the Grid Rail=s vertical surface. Although exposed to the elements, the cord will be wrapped with weatherproof material of significant strength to avoid penetration by birds, or other hazards. Via satellite, a separately powered system provides a back-up in the event of Grid sabotage or damage. In an emergency, the Grid backup system can be powered, short term, by the energy stored in each Grid compliant vehicle=s batteries, allowing Grid vehicles to exit in the normal course, via Phase I protocol, with no Grid computer input.

9.5Not Effected by Weather:

As the Grid Rail is elevated above the surface of the surrounding terrain and does not hold water it is not substantially affected by snow, rain, surface flooding or the typical debris field associated with surface roadways. All electrical components are out of harm's way, however, easily accessible by boom truck or scaffolding from the underlying roadways.

9.6Re-coating, Resurfacing:

The Company estimates that the Grid Rail will require painting or coating every six (6) to twelve (12) years and resurfacing every ten (10) to fifteen (15) years. Grid Columns are expected to need replacement or major repair every seventy-five (75) years.

9.7Computer and Electrical:

All other costs associated with the Grid and its maintenance are associated with the Grid=s computer and electrical systems. The costs of computer and electrical maintenance cannot be projected at this time, however, will decrease as mass development of computer equipment needed for the HPR System results in greater economy of scale and lower costs.
