A wildfire suppression system is shown that includes a detector that can identify a wildfire threat from an approaching wildfire. When a wildfire is detected, a fire suppression system is activated to pump a fire retardant product, such as water or foam, through a fire retardant distribution system to supply the fire retardant to a series of water dispersion devices that are positioned to protect a structure and a set of landscape elements such as trees, flowers, bushes, and shrubs. Various embodiments can include automatic notification to local fire and police authorities of the presence of the wildfire, and can also include local electrical power generating units that can provide the electrical power needed to operate and control the wildfire suppression system.

There are certain tasks that require humans to proceed on foot over intervening terrain (that may include “improved” segments such as paved roads and bridges) from some starting point A to some objective or destination point B, and perhaps thence to additional points C and D. Exemplars of civilian endeavors include forest firefighting, search and rescue, surveying, exploration, and recreational hiking. Military applications include infantry and special operations forces movements. In many of these endeavors, it is desired to be as rested as possible when reaching the destination in order to have the energy remaining to successfully or optimally accomplish some “objective” activity. The present invention provides a methodology for computing the route for a human being traveling on foot over arbitrary terrain from any point A to any other point B (and if desired to points C, D, etc. beyond) such that the human energy expended walking from Point A to point B (and any points beyond) is minimized. The energy-minimizing human ground routing system (EHGRS) enables recreational hikers, Army and Marine Corps infantry patrols, special operations forces, forest firefighters, geologists and search and rescue teams to quickly find the energy-minimizing route between any two points over any terrain so that they arrive at their destination with the minimum possible degradation of their performance due to fatigue, in contrast to routing developed based on human judgment.
