A Low Temperature Stirling Engine is a closed cycle heat engine . To understand how a Stirling Engine works, we need to identify its major components. Take a look at the picture below for a run down on the major parts. How does a Stirling Engine work? The Stirling Engine requires a temperature difference between two plates in order to run. In order to power the Stirling Engine, we need to have one plate hotter than the other. The gap between the two plates is sealed, containing a fixed volume of air. As the piston rises, the flywheel is turned.
The turning flywheel raises the displacer again, pushing air back to the hot plate, and so the cycle continues while there is still a sufficient temperature difference between the two plates. Low Temperature Stirling Engine Running On Hot Coffee Temperature Difference Because the Stirling Engine needs a temperature difference between the top and bottom plate to run, you don't need a heat source to power it. Free Piston Stirling Engines. Stopping Time (Visually) Recently, Nate True of Cre.ations.net posted a very nice project involving some water, some electronics to provide the illusion of time distortion.
(Time fountain) I have been long since interested in high-speed photography. Many years ago I built a very simple device using some aluminium foil, an air rifle, a couple of ligth triggered Flash units and, of course, a camera. The basic concept is this: You are in a dark room. If you synchronize a flash of light with the occurance of an event, you will see that event “suspended” in time without th need of highspeed photographic equipment. In the case of the Time Fountain, as Nate likes to call it, it has been always an interesting and fun phenomenon to watch at museums, or at home if you own a strobe light. We start with a water stream or constant rate. Is equal to the dripping rate , i.e., both will coincide at every time step. , where n is each time step.
There is a shortcut. Option #1Start with a constant water dripping stream. Option #2 . Blog Archive » DIY Fog Screen. If you’ve ever ridden latest iteration of the Pirates of the Caribbean ride at Disneyland, you will remember how, right before you hit the first drop, you are greeted with the ghostly image of the tentacle-faced Davey Jones creature warning you that “dead men tell no tales”. I certainly did. The effect uses rear-projection video, shined onto a screen of water vapor created by ultasonic atomization, that is sandwiched between 2 laminar airflows, which keep the sheet of fog contained.
The commercial Fog Screen that spits out this screen costs tens of thousands of dollars for the small one. I attempted to create my own cheap version of this system using a wooden box, a window fan, some drinking straws, and a cheap fog machine. I almost succeeded. The original idea was to mimic the commercial unit, and sandwich the fog between 2 sheets of air. I made my fog chiller with a 25 foot length of dryer duct coiled inside a garbage can. Thoughts on further development: Here are some more build photos.
