If you have 5,000 liters of water stored 30 feet high, you can get:
➡️ ~124 watt-hours of potential energy
➡️ But with 50% efficiency (real-world losses), you only get ~62 watt-hours
That’s enough to:
🔋 Fully charge a laptop once
💡 Power a 10W light for ~6 hours
📶 Run a Wi-Fi router for 3–4 hours
To power a 50W laptop for 8 hours (400Wh), you’d need:
💦 ~32,000 liters of water falling from 30 feet every day
