* Attaches to ceiling of structure
* Has some sort of sensor to identify charging port, perhaps on the charger end itself
* Has some limited range of mobility - 2'x2' with X & Y axis movement
* Cord unreels down to the charging port once it is reasonably lined up
* Charging cable has Macbook style electromagnet, reaches "charging zone" and activates, inserting itself
* Safety checks are done, wattage is pumped into the cottage if all is well
I honestly don't know if this is better or worse, it's definitely less cool.
