شومینه رایگان برای زمستان 😱! هر خانه‌ای به آن نیاز دارد اما هیچ‌کس این کار را نمی‌کند

In this video, inventor 247 demonstrates a simple yet powerful DIY free fireplace that uses a magnet and a copper pipe. The device generates heat through the vortex effect as the pipe moves through a magnetic field, producing silent, safe, renewable heat without fire, gas, or electricity. It is ideal for emergencies, workshops, garages, camping, or winter survival. The video explains how magnetic heating works, which magnets produce the most heat (neodymium), how to choose the right copper pipe, step‑by‑step construction, how to increase efficiency with airflow and motion, real temperature tests, and safety tips.
