The Mendocino Motor is a magnetically levitated, solar-powered electric motor. It consists of a spinning shaft held up by repelling magnets, stabilized by resting a point against a wall. The rotation is powered by solar panels mounted on the shaft, generating currents through coils of insulated wire.

The motor is EXTREMELY WELL-MADE, with a brushed aluminum alloy bottom plate, a CNC-finished frame with a sandblasting treatment, an aluminum alloy flywheel, and a stainless steel laser-cut connecting rod. The heating cylinder is made of custom-thick glass material, ensuring long-term heating without pressure. The overall model shape is refined, combining texture and beauty.

As an added bonus, the package includes spare glass tubes and O-rings, allowing for easy replacement in case of breakage during shipment or usage. Customers can contact the manufacturer for support or request future parts as needed.

OPERATION IS EASY – simply place the stirling on a cup of hot coffee, and it will run magically. As the coffee cools, the temperature difference slows the motor down, making the coffee suitable for drinking. The device can also be used on top of ice cubes, with small ice cubes placed on the upper plate to create an even greater temperature difference, resulting in faster and more exciting operation.

This product is an AMAZING and FANTASTIC gift option for a wide range of applications, including kids' science projects, physical/mechanical learning, teacher's demonstration props, and birthday gifts for friends, families, parents, and kids. Many of the manufacturer's customers come from schools and colleges, further highlighting the versatility and educational value of this product.
