“So what defines this project as being pretty distinctly different from any other project that I’m aware of is that we try to do things as cheap and simple as possible with a mind to making a sustainable package of integrated village technologies accessible to, if possible, everyone in the world.” – LEF cofounder Alexis Zeigler

LEF functions through the use of various sustainable technologies, many of which had to be developed specifically for the project. These can be categorized into four main groups: electrical, agriculture, plumbing, and heating.
