A hand-cranked fan, moving miniature steamships, wooden flying wings, and many other intricately made carriage, and house models to scale, Lynn even saw a prototype of a water wheel in the center of the workshop.
This was a round wooden wheel with a diameter of around 1 meter, from the water tank above the workshop, a continuous stream of water flowed down, driving the wheel to rotate ceaselessly, and at the same time turning the giant fan in front of it slowly, providing a cool breeze for the visitors entering the workshop.
Truly a waste of good material...
Lynn shook his head; this device could be used for irrigating fields or even generating electricity with no problem, but Lydia only thought of using it to power a fan.
Seeing Lynn shake his head and sigh, Darren's heart suddenly leapt to his throat. Although Lydia's toys were quite interesting, they definitely couldn't compare with the alchemical tools of the wizards.
