Sure thing—think of the coaster as a massive, oscillating asset. Start by mapping every surge of energy into a line item: solar panels, turbines, regenerative brakes. Then, treat the ride’s “chaos” as a volatility buffer—set aside a contingency fund equal to, say, 15% of projected operating expenses. Forecast revenue from ticket sales and the grid feed‑in tariff, then apply a discount rate that reflects the risk premium of a moving amusement ride. If the net present value stays positive and the payback period is under five years, the budget sheet will look tidy. Otherwise, trim the lift height or replace one of the generators with a more efficient model. In short, quantify every wobble, give it a cost, and keep the bottom line lean.
