In this video, the creator demonstrates how to use an old motor, a copper pipe, and a magnet to build a simple DIY device that can provide free hot water all year round. By inserting the copper pipe into a discarded motor and leveraging basic magnetic principles, the system heats water without the need for gas or electricity, offering a cheap and eco‑friendly heating solution for winter. The project is presented as a creative, sustainable invention that encourages recycling and saves money on heating costs.
