Ben Krasnow 3D prints a clear Einstein-Szilard refrigerator powered by flame
Maker Ben Krasnow has constructed a transparent, 3D-printed absorption refrigerator based on the historic Einstein-Szilard design, proving that an open flame can drive a cooling cycle without mechanical compressors. The project brings a classic thermodynamic invention to life, allowing observers to see the phase changes inside the pressurized fluid loop.
