Features

• This is a handmade Stirling engine based on research results of JAXA (Japan Aerospace Exploration Agency).
• It has a simple structure and is very easy to assemble.
• The operation is a piston type that moves on a mug filled with hot water.
• By adjustment, it can run for about 1 hour using 1 cup of hot water as a heat source.
• Experience the energy of new possibilities.
• A highly efficient free piston engine that uses the linear motion of the piston directly, and can be moved using hot water as an energy source.
• Earth-friendly eco-friendly (low-pollution) engine that uses solar heat and waste heat. Operated by gas expansion and contraction due to temperature differences, it can respond to any heat source.
