I do not know how the others are used. There are none in North America.

There have been tens of thousands of Pneumatic Tube Systems installed in North America and else where in the world. These are exactly the same technology as P.C.P.'s.

There have been 4 extra large P.C.P.'s installed as people carrying subways. We understand the latest was installed about 1960 to transport senior military officers from the Pentagon to security bunkers in the Virginia hills.

Other medium and large sized Pneumatic Capsule Pipelines have been installed elsewhere in the world that no longer exist or we are not supposed to know about. All use the same basic technology.

Hello Mr. Weaver,

To Clarify;

My initial inquiry was almost nine years ago and an oversight on my part and I neglected to delete it years ago, as I had forgotten about the twin pipe system installed by Drs. Kosugi and Liu in and the Sumitomo Pipeline Engineering group in 1980 replacing the quarries original dedicated rail line which was installed in 1937 when the quarry was developed for cement feedstrock production by the Tochigi Cement Corporation and then later purchased by the Sumitomo Cement Group.

The twin pipe system at the Karasawa Limestone mine was designed by Dr. Kosugi and Dr. Liu and the installation of the system was managed by Dr. Kosugi and Dr. Liu.

The twin pipe system at the Karasawa Mine transfers 2 million tons of sized limestone ore to the cement mill annually and has transferred 62 million tons of limestone ore since its intallation in 1980.

The other dedicated system was designed and managed by Dr. Kosugi and Dr. Liu for the construction and completion of the twin track Akima railroad tunnel in 2004 for the Japan Railway Corporation and its Shinkansen train service.

The last vertical P.C.P. system was employed for the last Tokyo Subway extension project in 2004-5 where a shallow vertical PCP was employed as the tunnel spoil transfer system to the surface for disposal at a rock dump.

The conveyor belt exiting the tunnel boring machine fed the loading pocket for the vertical P.C.P. employed there.

I have illustrated the two systems mentioned previously in my white paper as well as describing how a Pneumatic Capsule Pipeline can replace the use of haul trucks in the Powder River Basin coal fields and the strip mining done in the east for coal as well as how a PCP system can be employed for transporting salt and other ores as well as transporting the 200 foot layer of sandstone overburden stripped from the Wyodak Coal seam in the Powder River Basin of Wyoming and Montana at much less cost than using haul trucks with the 3-400 ton payload class of haul truck consuming 64 gallons of fuel per hour with its built in inefficiency of 50 percent and adding employment in the coal fields from the savings due to the removal of the haul truck as a means to transfer coal and overburden at $200.00 Per Foot U.S., subject to inflation versus 3 million dollars per haul truck plus the $720,000 dollars in annual tire expense and the 560,640 gallons of diesel fuel consumed by each haul truck

plus salaries and parts as these machines operate at a very poor fifty percent net efficiency versus the Pneumatic Capsule Pipeline with ninety eight percent efficiency.

As Dr. Kosugi always said the biggest expense is the pipe. ■
