This movie shows how an electric car, home appliances like a cooker, washing machine, fridge etc. are communicating and sharing energy in a smart home. During a grid outage the local storage unit and the solar panels are supplying energy in a temporarily micro grid.
This movie shows the results and thoughts of a smart home project (proof of concept) where devices are forming an independent smart grid (Scene).
An electric vehicle is also approached as a smart device (storage) which will be recognized and accepted by the system automatically as a guest (Dude).
A lot of issues are real, some of them are manipulated.
The character of the Dude is based on the big Lebowski
