Why batteries don't belong in forests
An AI device is cheap. The trip to change its battery is not.
A small AI device costs less than a good dinner. Putting one in a forest is easy. Keeping it alive is the hard part, because every battery eventually needs a person, a vehicle and most of a day to reach it.
Multiply that trip by thousands of devices and ten years, and the battery, not the electronics, becomes the real cost of the network. It is also the reason most environmental networks stay small: nobody can afford to visit them.
Batteries come back as waste, when they come back at all. Many are simply left where they died.
Solar helps until it doesn't: under a canopy, through a northern winter, at night. The places we most want to watch are often the places sunlight reaches least.
Plants are already there, working every hour. The microbes around their roots never stop feeding. An AI model powered by the plant it sits beside never needs a visit. That is the whole idea behind Fyto.
