Capital costs seem rough. You can’t use a normal wall plug for a supercharger. How many amps do they pull, 200? You would need a new breaker box and the super charger hardware.... say 10k per house.
Who is going to spend 10k to get a charger in their driveway strangers can stop by and pay you $20 to use?
Uber works because people already own the car. Even EV people don’t already own a supercharger, they have a much simpler one.
The startup would install the charger and split the fee with the homeowner.
Anyone want to work on that with me? Or feel free to critique. It’s sort of like air bnb for car charging.
