          It actually produces a decent amount, when it produces. The only issue is there is nowhere on earth that gets enough rain for this to be a stable venture.

      Yes. These kinds of systems are already in use and you only need somewhere between 1 and 2 meters of drop (minimum) to produce an amount of energy.

      Yes, it is possible. It’s just a dam inside a building. The collection area is very small to the point where it makes no sense to deploy this. I’m skeptical you could achieve an EROI above 1 without an insanely tall building and a system that was cheap to manufacture, install, and maintain. It’s no longer low hanging fruit, there are tons of better alternatives that can be employed. There is no practical situation in the world where this is a competitive option.

      If the building was 100m tall, and received 1m of rain per year, with a catch area of 100m^2, you’d get about 270kwh of power per year, worth about $30.

      It’s never enough to qualify something, you have to quantify it, and then put it into context.

        Isn’t it 27 kWh

        A = 100(m^2) catch area
        h = 1m rainfall / year
        >V(dot) = A * h(dot)
        V(dot) = 100(m^3 of water) / year
        p = 1000kg / (m^3 of water)
        >m(dot) = V(dot) * p
        m(dot) = 100,000kg
        H = 100m tower
        g = 9.81m/(s^2)
        >E1(dot) = m(dot) * g * h
        E1(dot) = 98,100,000J / year
        c1 = kJ / 1000J
        c2 = W * second / J

        >E2(dot) = E1(dot) by conversion

        E2(dot) = 27.25kWh / year
        >P = E(dot)

        "power"
        27.25 kWh of ENERGY per year.
        27.25 kWh / year is the POWER

      Let’s consider the best possible scenario ever.
      The most rainy place on earth has 8 meters of rain a year.
      The tallest building is 1 km tall (jeddah).
      The area of jeddah is 2500 m2
      Every year it would capture 20.000 m3 of water.
      20.000.000 kgs of water.
      They have a potential gravitational energy of 196 ×10^9 j/year.
      Roughly 6 kilowatt.

        I don’t know what part of this you want examined. Increased height will grant greater gravitational potential at the cost of additional material; extremely large structure will have to be exponentially concerned about damage/instability from forces like wind and earthquakes. Increased area will grant greater working mass. There is probably a relationship between the tower, balloon, and tarp that resembles a catenary in the absence of rain that will eat away at your theoretical effective area per area of tarp material used. You’d also be limited on the possible size of the tarps and balloon to properly support dynamic loads from the rain water. Like anon said,

        The balloons require helium refueling so it’s not true perpetual motion.

        you’ll need to keep refueling the balloons, and this could probably be better addressed with static members will less energy "leakage". I wonder what could be said for the energy not lost to air resistance from the rain drops falling through the air, but having laminar flow down the pipe; I would assume it is insignificant, but I’m just eating lunch, not going to bother with it.
