Magnetic Cracked Pot

submitted by: SirZerp
The magnetic fields of a cracked pot. Note - the blue ring in the center is from having two different magnets; the bottom volume is like a large ring magnet and the top is like a cylinder magnet. The interaction between the two, top and bottom, produces the blue ring eddy of flux. Also a capacitor with horizontal plates has the same field values as a vertical aligned magnet. In other words, you could design a capacitor that has the same field as the object in the video, but it would be...

CES 2014: SmarterShade uses optical filters to revolutionize window shades

submitted by: nsf
This demo at the CES 2014 from small business SmarterShade shows one of several possible applications for their window shading technology--images hidden in glass revealed by the precise position of optical filters. Though smart window technology has been around for a while, cheaper, more adaptable options are needed. SmarterShade is one of nearly 30 exhibitors funded by NSF this week at Eureka Park, which features new grassroots technology. Read more: http://go.usa.gov/ZPvk

Science Behind the News: Bio-inspired Materials

Harvesting Electricity: Triboelectric Generators Capture Wasted Power

submitted by: nsf

With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs--with no batteries or power cord. A professor at the Georgia Institute of Technology, Wang is using what’s technically known as the triboelectric effect to create surprising amounts of electric power by rubbing or touching two different materials together.

Generating Electricity More Efficiently with Multiphase Thermoelectric Converter

submitted by: MFerreiraJr
The Multiphase Thermoelectric Converter is a direct thermal-to-electrical energy conversion system designed in order to harvest most of the waste heat energy efficiently into electricity. Conceptually, it works by ionizing hot coolant in order to force it F=q(v × B) to push its ions against moving magnetic fields doing useful work converting thermal energy directly into electric power at high efficiency with almost no moving parts. Essentially, it can be comprised of two sets of concentric...
