Water powered funicular with equal masses?

In summary, the paper introduces a modified water-powered funicular technology that has the potential to be used in Nepal. The funicular would work even if both cars or wagons have the same mass, and the physics has been revised by Uday Raj Khanal, a respected physicist. However, the funicular may not work best if the loads are equal, and there is still friction involved.

TL;DR Summary
Water powered funicular with equal masses?
I found a paper (https://www.researchgate.net/publication/312123871_Introducing_a_Modified_Water_Powered_Funicular_Technology_and_its_Prospective_In_Nepal) where the authors design a funicular system powered by water but with a modification from traditional systems where apparently the funicular would work even if both "cars" or wagons (the one at the top and the one at the bottom) have the same mass.

Apparently, as the paper says, the physics was revised by Uday Raj Khanal which is a respected physicist in the authors' native country. But even then, could this funicular be built? Could it work?

Sure, I don't see a problem - it just oscillates. In practice though, the cars will be different masses, otherwise there'd be no point to it.

The funicular will start just fine, with equal masses. There's still friction : it won't complete the journey without some energy input. It's just a way of making it faster.

But the authors seem to imply that even with the same mass, the whole route of the funicular could be completed, right?

I didn't give the paper more than a cursory glance, but I seriously doubt anybody who's "respected" would claim that.

The system probably works best if the loads are equal, but it isn't the dreaded "perpetual motion" by any stretch of the imagination : in fact there's a little bit more friction involved because of the longer tracks (mitigated - perhaps completely - by less regeneration involved in ac/decelerating the cars).

Maybe, cut and paste the section you have problems with ?

FAQ: Water powered funicular with equal masses?

How does a water powered funicular work?

A water powered funicular uses the force of water to move a carriage up and down a steep slope. The carriage is attached to a cable, which is connected to a water wheel. As the water wheel turns, it pulls the carriage up the slope. When the carriage reaches the top, the water is released, causing the water wheel to turn in the opposite direction and bring the carriage back down.

What are the advantages of using water as a power source for a funicular?

Using water as a power source for a funicular is environmentally friendly and sustainable. It does not produce any harmful emissions and does not require any fossil fuels. Additionally, water is readily available and can be sourced from natural bodies of water or recycled.

How does the weight distribution of the masses affect the operation of a water powered funicular?

The weight distribution of the masses is crucial for the proper functioning of a water powered funicular. The masses on either side of the carriage must be equal in order to maintain balance and prevent the carriage from tipping over. If the masses are not equal, the carriage may become stuck or move unevenly.

Can a water powered funicular be used in any location?

A water powered funicular can be used in most locations, as long as there is a source of water and a steep slope. However, the slope must be carefully designed to ensure the funicular operates safely and efficiently. Additionally, the water source must be reliable and have enough flow to power the funicular.

Are there any safety concerns with a water powered funicular?

As with any form of transportation, there are some safety concerns with a water powered funicular. It is important to regularly maintain and inspect the funicular to ensure it is in good working condition. Additionally, proper weight distribution and slope design are crucial for the safe operation of the funicular. It is also important to have safety measures in place, such as emergency brakes, in case of any malfunctions.
