This is a most excellent place for technology news and articles.
An early version of the Petřín ropeway in Prague used to contain tanks in both cars. The upper one would be filled with ~~sewage~~ collected rainwater from the city's hilltop quarter and the energy of the descent was used to pull the other car up. Additionally, the way up cost twice as much so there was an incentive to ascend on foot, which was about as fast despite the incline.
Neat.
