The Forest Walker is an idea that integrates sensors, computation, actuated machinery, power conversion and electronic communications to create a machine that roams the forest harvesting the most widespread and least dense energy source available: Wood. Concurrently, the Forest Walker converts this gathered fuel into a usable fuel format, doing so unattended for long periods of time. Once converted, the fuel is fed to an internal combustion engine that drives a generator to constantly produce electricity. That electricity is used to drive hydraulic pumps, computers, sensors, and Bitcoin miners.

The Forest Walker is about as low time preference as it gets.
