The ideas presented here are protected by US Patents 7,819,345,  7,942,350,
      Canadian patent 2,693,158 and a pending Canadian patent for the Spray Hose Chamber.
     The Spray Hose Chamber has been awarded a US Patent that can be seen below.

     I am not able to build these systems via a startup company because of family health issues.
     I hope to license the inventions to US and Canadian companies.
     For the rest of the world, I encourage people to build and sell these systems anywhere except the US and Canada.
     I will assist "rest of the world" companies, for free, with the construction of these systems.

      La Cámara de Mangueras de Spray ha sido galardonada con una Patente de EE.UU. cuyo número estará disponible en breve.

      No soy capaz de construir estos sistemas a través de una empresa de inicio debido a problemas de salud de la familia.
      Espero licenciar los inventos a compañías estadounidenses y canadienses.
      Para el resto del mundo, animo a la gente a construir y vender estos sistemas en cualquier lugar excepto los EE.UU. y Canadá.
      Asistiré a las empresas del resto del mundo, sin costo, con la construcción de estos sistemas.

The above photo shows 200 ft of hose that can protect a home from wildfire embers, and also confine a prescribed fire (RxFire).
There is a spray nozzle every 10 ft that sprays water onto the adjacent area.

At the top of the photo below is a fire hose that has a small hole for spraying water.

Below the top hose are two rectangular sections of hose that have been glued together.
One rectangular hose section has a smaller rectangle cut from its center.
The other rectanglular hose section has two holes that are centered in the cut rectangle area.

The photo below shows the two rectangular hose sections glued to the longer fire hose section.

When water is pumped into the long fire hose, some the of the water exits the hole in the hose.
This water enters the chamber formed by the rectangular area removed from one of the rectangular 
hose sections. The water in the chamber then exits from the two hole shown in the photo.

If a hose has a single hole, the water exiting will form a narrow column. The water exiting the two holes
does not form columns, but actually forms a very wide and deep spray. The wide and deep spray pattern 
is very desirable for fighting a grassfire or low intensity wildfire.

The two rectangular hose sections have a very low profile, and are flexible.
This makes them useful for creating a long spray hose with such nozzles.
Their low profile allows such a hose to be deployed from a reel.
Such a hose can also be folded and deployed from a storage cavity.

This spray hose chamber design has been granted a US Patent. A Canadian patent is pending.

The image above is a Hale fire pump that drives the hose system.
It can deliver 300 gpm at 70 psi.

The image above is a swimming pool that supplied the water to the Hale pump.

Earthquakes often break water mains. The quakes usually start many fires. If water mains are broken, the firefighters won't have water to fight the fires. Drinking water is also needed by the population of the earthquake region.

IFFC proposes
a very long portable hose system that can be rapidly deployed to deliver water to fight wildfires.
It also can be delivered, by ground or air, to locations that have lost their water supplies because of earthquakes, floods, and large storms.

The system will be computer controlled so that it will be easy to operate.

The long hose system can bring water from 10, 20, or 30 miles away. There is actually no limit, other than expense, to the length of the hose system.

The figure above shows pickup trucks with portable diesel pumps and hoses on reels.
The pickup trucks have deployed the hose, from the reels, while driving across the terrain.

The hose contains a small gauge wire that supports a digital data network which,
by remote control, monitors and controls all of the pumps in the system.
Multiple pumps are needed when water is pumped long distances.
Hoses have limited ability to handle very high pressures, so that multiple pumps are needed
to boost the pressure at given intervals.

All of the pumps in the relay can be controlled by a personal computer that is driven from a control panel.
Once the hose and pumps of the system are deployed, there is no need to dedicate an operator
to control each pump.

The figure below shows that tractors can be used instead of pickup trucks.
The picture below shows an existing military system that delivers water and diesel fuel to forward posts.
The hose shown contains an embedded wire that is used to prevent static electricity from igniting diesel fuel.

We plan to use this type of hose in the proposed hose system. The embedded wire will support an Ethernet type digital network that performs the monitoring and control of all of the diesel pumps in the hose system.

The picture below shows a much smaller reel that can be used to deploy the proposed hose system.
 The image below shows that it is possible to deploy the hose system over very rugged terrain via a large helicopter.
