In this video, inventor 247 demonstrates how to build a free winter fireplace using magnets and a copper tube, leveraging the effect of eddy currents to generate heat without fire, gas, or electricity. The system is quiet, safe, renewable, and suitable for emergencies, workshops, garages, camping, or winter survival. The video explains how the magnetic heating effect works, which magnets produce the strongest heat, how to choose the right size copper tube, step‑by‑step assembly, ways to increase efficiency with airflow, a real temperature test, and safety precautions.
