The figure above shows a home being protected by a wall of water created by the new SprayHose.
The most commonly used device to protect homes from wildfires are irrigation sprinklers.
They are expensive and take a long time to deploy.
The SprayHose is very low in cost and deploys very quickly.
The image above is the patented spray nozzle.
Spray nozzles are placed approximately 10 feet apart along a hose line.
Unlike a sprinkler array, the SprayHose can be deployed very quickly.
The spray hose will have devices that hold the spray nozzle at desired angles to the ground. Devices are being designed that can lay flat on the ground or be staked into the ground.
The above image shows a piece of PVC with a rectangle cut into it. The PVC is surrounding a hose with a smaller rectangle centered in the PVC rectangle.
The photo above shows that a piece of hose with two holes is placed on top of the PVC. This completes the SprayNozzle.
The photo above shows the HFX hose from All American Hose.
A propane torch burns at over 3000 degrees F.
After 1 minute of flame exposure the top layer of the spray nozzle was warped. The right side of the burned section was cut with a knife to see the damage to the PVC. Note that the printing on the PVC is only slightly affected.
The hose is extemely flame resistant.
The pump shown above can supply water to 50 feet SprayHose.
Longer hoses will require larger pumps.
The SprayHose requires much more water than a household garden faucet can supply.
The water tank shown above can supply the needed water at low cost.
A typical single spray nozzle can deliver 15 gallons per minute of water.
