It may be a Tesla project.

Bob was showing me that they set up the boxes (about the size of a cereal box, that beamed light and hit something on the modified tractor, so that the farm field could be leveled to a fraction of an inch. It helped with the irrigation water.

Bob Otondo was a good person and it pleased me that he got in at the beginning of a new development.

I do not know if it is still in use and expect he is up in Heaven now.
