Title          
Jumping droplets help heat transfer 
   
 
Abstract
Excerpt from MIT's Research Update - Many industrial plants depend on water vapor condensing on metal plates: In power plants, the resulting water is then returned to a boiler to be vaporized again; in desalination plants, it yields a supply of clean water. The efficiency of such plants depends crucially on how easily droplets of water can form on these metal plates, or condensers, and how easily they fall away, leaving room for more droplets to form. The key to improving the efficiency of such plants is to increase the condensers’ heat-transfer coefficient — a measure of how readily heat can be transferred away from those surfaces, explains Nenad Miljkovic, a doctoral student in mechanical engineering at MIT. As part of his thesis research, he and colleagues have done just that: designing, making and testing a coated surface with nanostructured patterns that greatly increase the heat-transfer coefficient.

The results of that work have been published in the journal Nano Letters, in a paper co-authored by Mil...

Title          
Business Plan for Online Money Transfer 
   
 
Abstract
This is a detailed business plan proposing an online money transfer system, very similar to what PayPal is today, that we proposed to a panel of Indian VCs in 2001 but was not funded on assumptions that Reserve Bank of India will not allow such radically different money transfer methods to be implemented. The plan, proposed at the same time when PayPal was also just getting started, allowed online transfer of money, virtual cash and micro payments, .

Title          
MIT Researcher Joe Pompei's Audio Spotlight  
   
 
Abstract

The Audio Spotlight uses a beam of ultrasound as a "virtual acoustic source", enabling unprecedented control of sound distribution. The graph to the right shows the real sound field of the Audio Spotlight versus the theoretical maximum directivity of any loudspeaker, panel, dome, or "shower" of the same size. As shown by this comparison, no loudspeaker in the world can approach the level of control provided by Audio Spotlight technology. For more on the theory of this device, go to http://www.holosonics.com/tech_directivity.html or download Joe Pompei's PhD thesis from DSpace at MIT Joe Pompei's PhD Thesis

Title          
high speed camera: lighter 
   
 
Abstract

A high speed camera is a device used for recording slow-motion playback films, or used for scientific study of transient phenomena.

http://en.wikipedia.org/wiki/High_speed_camera 

A normal motion picture is filmed and played back at 24 frames per second, while television uses 25 frames/s (PAL) to 29.97 frames/s (NTSC). High speed cameras can film up to 250,000 frames/s by running the film over a rotating prism or mirror instead of using a shutter, thus reducing the need for moving parts. Using this ...
