The Wow Moment

It's 2 AM in a drafty Manhattan apartment. Sarah opens the HeatThief app and sees 12 nearby buildings lit up in red—each literally leaking heat into the atmosphere. The Sterling Tower across the street? Venting 850 kWh of excess heat every hour. With one tap, her building subscribes to receive that waste heat. Within hours, her radiators warm up using energy that was previously vanishing into the sky. Her heating bill drops 40%. The Sterling's management gets paid for their waste. Everyone wins. The magma beneath our feet finally works for us.
