#Solarcity Has a New Plan to Make Distributed Energy an Integral Part of the Grid Solarcity has an idea for how to help California utilities tap their own customers as an integral part of their billion-dollar distribution grid plans:

The human navigation function is operated by two types of brain cells-place cells and grid cells.
while grid cells provide us with an absolute reference system, so we can determine exactly where we are on a map.
The human brain uses grid cells, which provide a virtual reference frame for spatial awareness to handle this type of relative navigation.

and we know our relative movement in relation to those coordinates. By using both place and grid cells for navigation,
humans and animals are able to accurately move through the environment. Yuan and the team have implemented the same neural scheme for robots,
