If you reverse the temperature differential, and cool the plate that was warm, and warm the plate that was cool then the engine will run in reverse.

As the air heats up it expands, and as it cools down it contracts. This expansion and contraction drives a small piston which in turn drives the flywheel. The clever thing about Stirling engines is that the mechanism for cycling the heating and cooling of the air is built into the engine in the form of the displacer, which is driven by the flywheel and moves the air from the warm side to the cool side and back again over and over.\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003ch2 class=\"style6\"\u003eEco-friendly\u003c\/h2\u003e\n\u003cp class=\"just\"\u003eThe Kontax KS90 Low Temperature Differential Stirling Engine is the ultimate eco-friendly device, showing with one spin of the flywheel a clean and simple way of converting waste heat into motion.

There is a hot side and a cold side to the engine. Provided there is a large enough temperature difference the engine will run. Stirling engines work by cyclically heating and cooling the air inside the main chamber. As the air heats up it expands, and as it cools down it contracts. This expansion and contraction drives a small piston which in turn drives the flywheel. The clever thing about Stirling engines is that the mechanism for cycling the heating and cooling of the air is built into the engine in the form of the displacer, which is driven by the flywheel and moves the air from the warm side to the cool side and back again over and over.The Stirling engine is named after its inventor, \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Robert_Stirling\" target=\"_blank\"\u003eRev.

Kids (and adults!) can watch marbles going down a track, passing through various obstacles, for hours on end.  Marble runs are fascinating, they grab our attention, and yet they're also relaxing. Marble runs and races have become an unexpected YouTube phenomenon, with thousands of videos racking up millions of views. You choose a marble to watch, to cheer for, you wonder which path it will take, you put yourself in the marble's place, imagining that you are right there with the glass ball, going on a marvelous, unknown journey, with twists and turns and surprises around every corner. The thrill is even greater when you've built the marble run yourself. Now you're not just passively watching a video, you're fully invested because you built a wondrous machine with your own hands.\u003c\/p\u003e\n\u003cp\u003ePresenting the Ugears Marble Run Chain Hoist—an exciting combination of art and engineering. The Marble Run Chain Hoist is both a beautiful kinetic sculpture and an intricate toy that teaches as it entertains. This DIY wooden marble run features a chain hoist powered by a hand crank, and a series of tracks, each with its own unique and fun obstacle or element. Turn the handle clockwise to set the machine in motion, and watch as the wooden chain hoist collects and lifts the marbles to the top of the machine, where a 3-way switch distributes them on different tracks. One marble plunges down a chute with a loop-the-loop at the bottom; the next tumbles down the various stages of the cascades, while three others are collected in the accumulator then released down one of three short tracks. All marbles pass through the common tray or collector before returning to the chain hoist to be lifted on their next journey.\u003c\/p\u003e\n\u003cp\u003eThe Marble Run Chain Hoist is modular, and can be connected to other Marble Run Chain Hoists (2 or 4 models can be connected, in pairs) using special connectors (included). Attach two Marble Run Chain Hoists together frontally, or connect four together, both frontally and laterally, for a mini system of hoists and runs.\u003c\/p\u003e\n\u003cp\u003eThe world's tallest rolling ball sculpture, at 72 feet, is the \"Energy Machine,\" located inside the Hong Kong Science Museum. At one foot tall our Ugears wooden marble run may not be the biggest, but we think it's the cutest! Multiple elements are packed into a compact space in our DIY Marble Run Chain Hoist, keeping you guessing which path your favorite marble will take. As marbles enter the 3-way switch each marble closes a \"door\" behind it, allowing the next marble to pass further. The third marble, passing through the last hole, opens the doors using a lever.\u003c\/p\u003e\n\u003cp\u003eExperience the satisfaction of building your own intriguing, 3D puzzle\/kinetic sculpture\/marble run with your own hands. Everything you need for this fun DIY project comes right in the box, including pre-cut wooden boards, 10 marbles, wax and sandpaper (for optimal gear function). Each Ugears model kit, 3D puzzle, or brain teaser comes with a set of detailed, illustrated instructions in 11 languages. The Marble Run Chain Hoist has 400 pieces, is rated \"Medium\" level, and has an estimated assembly time of 7 hours. As you build this ingenious wooden marble run, you will learn about the action and interplay of drive gears and driven gears in gear sets, the delicate action of counterweights, and be intrigued by the mechanics of the 3-way switch and accumulator as they determine the marbles' course.\u003c\/p\u003e\n\u003cp\u003eYou and your family will have hours of fun constructing this DIY kit together, without need of glue or special tools. Just snap the wooden pieces out of their laser pre-cut boards, then snap them together and watch your marble run take shape. Our high-quality precision laser-cut pieces are made from natural wood composites, have a wonderful smell, and fit together snugly. If you break a piece during the build, no problem! Ugears models each come with a few spare parts, and if it's a unique piece that's damaged or broken, just contact our customer service and we will gladly send you a replacement part free of charge! Free replacement parts—just part of Ugears' commitment to customer service.\u003c\/p\u003e\n\u003cp\u003eThe fun doesn't stop with the build. With static models the completed model often gets put on a high shelf collecting dust. Not so with Ugears! Once you finish building this DIY marble run the fun is just beginning! Watch the wooden puzzle come to life as you crank the hoist to send the marbles on their adventures. For anyone looking for a toy that will give more than 5 minutes of fun, a marble run is certain to capture the attention of any child (or adult!).\u003c\/p\u003e\n\u003cp\u003eLooking for a unique gift for home or office? The Marble Run Chain Hoist is an engaging way to relax your mind before going back to the task at hand, whether that's tidying your desk, sending out an email, or getting ready for your next zoom call. Everyone enjoys watching marbles pass through an intricate machine—it's just part of human nature! Perhaps there are some children in your life who would be delighted to help build this model and watch the marbles loop-the-loop, trickle down a counterweighted cascade, or take any of several other paths as they work their way to the bottom.
