If you live in a town nearby a steep mountain this is great for you to pay all your electric bills. Essentially there's a cable-suspended car elevator that comes down the mountain. A car drives up and can take the quick car-vater down to save on time and break pads. The car-vater generates electricity for the town. Obviously, this would be best for a road with a lot of traffic and you could charge people to go up the car-vater if they want to make the trip quickly.
