Meet MirageFox — an AI-powered retrofit device that captures waste heat from your window AC using vortex tube technology. Cut cooling costs by up to 30% while heating your water for free.
You install MirageFox in 10 minutes, turn on your AC, and watch our app show your hot water tank temperature rising from 50°F to 120°F in real-time — while your room cools down. That's free hot water that would have otherwise been wasted heat blowing onto the street.
Our patented vortex tube technology spins hot air at high speeds, separating heat energy that gets transferred to your water supply instead of being wasted outside.
Smart algorithms continuously optimize the heat transfer process, adapting to your usage patterns and maximizing energy savings 24/7.
Attaches to any existing window AC unit. No tools needed. Just snap it on, connect to your water line, and start saving immediately.
