Protecting Neighborhoods -
The figure below is an image of this special hose.
On the left is the hose chamber with the holes for the "spray curtain". On the right is the supply hose. The two hoses are bonded together to ensure correct orientation when deployed.
After deploying the hose, the firefighter can place the pump on the ground and drive the truck to a safe location to avoid the loss of the truck if the fire cannot be controlled. From a high vantage point, or a plane or helicopter, a firefighter can send commands to the pump and each valve box via a radio link. There commands will enable or disable spray in selected segments of the hose. The pump flow can be adjusted by radio.
Remote control of the system allows firefighters to remain at a safe distance while enabling the spray curtain only where it is needed.
The proposed system can be built from off the shelf components.
A one mile spray hose system could protect a neighborhood of 20 homes on 1/2 acre lots. The system would sell in the range of several hundred thousand dollars. This is a fraction of the cost of the many homes that might be lost to a wildfire.
