Stair lifts are common, at home and also in public places. The idea is to energize a stair lift with mechanical energy from a cycle or a hand lever so that when a user sits on the chair, their family members or friends ride the cycle (which is immobilized to the place) and take the user up the stairs.
  1. A fun way for a group to interact while at home or visiting a public place. If the user is alone, they could ask strangers to help them.
  2. To use a sustainable (renewable) source of energy
  3. It will keep people active, at least to help their loved ones.
How does it work?
The simplest design came to mind. A cycle has a chain and a chain wheel (derailleur). The chair lift will be attached to this mechanism. Of course, the cycle will have gears to ease the movement. To use it, the user will sit on the stair lift. Instead of using electricity to power it, the user's friends will ride the cycle to take the person up the stairs.

I propose providing the opportunity to lift the chair automatically as well for cases when the disabled person is alone at home, for using the lift at night, and similar situations. To not let the laziness of the family members get in the way with this, for automatic lifting, the system could use only the battery power, and the battery would be charged by cycling or using other manual lifting gear of the system. This way family members would be gently forced to exercise while at the same time helping the person in need.
I researched the topic a bit and found these manually powered lifts that might be of interest to you: 1, 2. Especially the vertical walking device seems promising, although I don't hear much talks about it since 2016, so perhaps it didn't get popular enough for some reason.

Povilas S Yes, it should have the provision of working on electricity.
The home idea is great. Family members could ride the bike and generate sufficient energy for the day. The ones who need to use the lift could then use it. When installed at a public location, it could be mechanical, as I explained in the session text. So, you need to ride until the person (on the lift) reaches the top. Of course, even here, an automatic override needs to be installed.
Of the links you shared, "1" is manual, right? "2" is much better I think. But for those who are much more immobilized, a lift is the best option.

Shubhankar KulkarniYes, the first one is a very simple option where you climb the stairs while sitting, as I understand, you need less force to do that, I imagine you just gently touch the stairs with your feet and the supporting mechanism helps to lift you up, when moving down the gear uses your potential energy to slowly and gradually take you down. It might be helpful for people who are not completely disabled (can't move their legs) but rather have trouble walking.
