Title          
3D Printing from MIT 
   
 
Abstract    
In this video, we show how MIT research continues to push the boundaries of the burgeoning technology of 3-D printing. The following excerpt is from the MIT news office webpage at http://web.mit.edu/newsoffice/2011/3d-printing-0914.html "The initial motivation was to produce models for visualization — for architects and others — and help streamline the development of new products, such as medical devices. Cima explains, “The slow step in product development was prototyping. We wanted to be able to rapidly prototype surgical tools, and get them into surgeons’ hands to get feedback.” 3DP technology involves building up a shape gradually, one thin layer at a time. The device uses a “stage” — a metal platform mounted on a piston — that’s raised or lowered by a tiny increment at a time. A layer of powder is spread across this platform, and then a print head similar to those used in inkjet printers deposits a binder liquid onto the powder, binding it together. Then, the platform is lowered infinitesimally, another thin layer of powder is applied on top of the last, and the next layer of binder is deposited."

Title          
Marble displacer Stirling Engine 
   
 
Abstract    

5 rolling marbles act as the displacer in this engine. The rigid connection between the piston and conrod is what tips the test tube, rolling the marbles.

Model of stirling engine realized by a syringe and a test-tube.

In the family of heat engines, 'Stirling engine' defines a closed-cycle regenerative hot air engine (or other permanent gas) engine, though the term is often used incorrectly to refer generically to a much wider range of hot air engine types. In this context, "closed-cycle" means that the working fluid is permanently contained within the system, whereas "open-cycle" engines such as internal combustion engine and some st...

Title          
Lamina Flow Stirling Engine 
   
 
Abstract    

This amazingly simple engine runs at 700rpm heated only by a small candle.

Thermoacoustic hot air engines (Sonic heat pump and refrigeration or thermoacoustic heat pump and refrigeration) of which nearly all are thermoacoustic stirling engines is a technology that uses high-amplitude sound waves in a pressurized gas to pump heat from one place to another - or uses a heat temperature difference to induce sound, which can be converted to electricity with high efficiency, with a (piezoelectric) loudspeaker.

This type of heat pump or refrigerator has no

Title          
Model of a stirling engine in motion 
   
 
Abstract    

Model of stirling engine realized by a syringe and a test-tube.

In the family of heat engines, 'Stirling engine' defines a closed-cycle regenerative hot air engine (or other permanent gas) engine, though the term is often used incorrectly to refer generically to a much wider range of hot air engine types. In this context, "closed-cycle" means that the working fluid is permanently contained within the system, whereas "open-cycle" engines such as internal combustion engine and some steam engines, exchange working fluid with their surroundings as part of the

Title          
Test of Rolls Royce Engine for Airbus 380 
   
 
Abstract    

A Discovery Channel footage of a destructive testing of a Rolls Royce jet engine. The idea is to see if the engine suffers a destructuve failure, all the fragments from the failure (blade parts, lethal shrapnels) are contained in the engine cover. This is an important part of the testing that ensures safety for passengers.

Rolls-Royce plc (LSERR.) is a British aircraft engine maker; the second-largest in the world, behind General Electric Aviation. The company has related b...
