Samsung's New Transparent 46-inch LCD Powered by Solar Energy
Samsung has recently revealed a transparent 46-inch LCD screen powered by solar energy. It is an upgraded model of a see-through LCD panel showed at the SID 2010 in Seattle, in May last year.
Harvard Student's Tweak Could Yield 20% Energy Savings in Microprocessors
Currently, microprocessors waste a lot of energy by not shutting down parts of themselves that aren't in use at the moment. Wonyoung Kim, a graduate student at the University of Harvard has designed a power saving mechanism that puts the various parts of the microprocessor to sleep right away after they aren't used.
Sharp Unveils LED Devices With Better Luminous Efficiency
Sharp Corp has recently unveiled an LED device that has a luminous efficiency of 91 lumens/Watt with an input power of about 25W, being used for lighting purposes.
Cyclus: A Spring-Powered Phone Charger by Japanese Designer
An idea by designer Satoshi Yanagisawa is using a spring, some gears and a small motor to produce about 3 watts of electricity. The 6-volt energy generator is hand-cranked, and its energy lasts for 30 minutes.
New Molybdenite Transistors Could Consume Some 100,000 Times Less in Standby Mode
The joint efforts of a team of researchers from the Laboratory of Nanoscale Electronics and Structures in Lausanne (LANES), Switzerland, have produced a new semiconducting material, made with molybdenite (MoS2). The new discovery could have important applications in transistors that are superior to silicon or graphene-based ones, in terms of size and energy efficiency.
New Chip-Embedded CIGS Solar Cells Could Account for Pollution Reduction
Rather than using the classic approach of a solar cell and a battery, researchers from the University of Twente, the MESA Institute for Nanotechnology have developed an interesting microchip that embeds a high-efficiency solar cell.
Ultra-Efficient Quantum Dot LED (QLED) Screens Developed by LG and MIT Spinoff
Just about the time when I thought buying a TV with an OLED screen is fancy and green, here's another news that intrigued me: Quantum-dot LED screens are actually greener and offer higher image quality than OLEDS, and they are to be produced by several manufacturers from the US, South Korea and Belgium.
Wise or Not: The U.N. Suggesting Rapid Replacement Of Incandescent Bulbs With CFLs
I had heard that the European Union wants to prohibit the production of incandescent lighting bulbs, but I never thought that would be possible in a short time. Frankly, on the one hand I'd be glad for the huge carbon savings this measure would give, but on the other the CFLs are not yet widely accepted by the eye, their light being much colder and giving your home an office-like feeling.
Cheaper OLED Technology Developed By German Researchers
The OLED (organic light emitting diode) technology has been known around for quite a while and lately its presence in the consumer products has been felt more intensively, though at a slower pace due to the costly manufacturing process.
MN103L: The Newest 32-Bit Microcomputer From Panasonic That Has Green Features
Panasonic has just announced a new type of 32-bit microcomputers specially built for saving power and for flexible designs. Their main achievement of Panasonic is a built-in flash memory, which is the biggest player in the power saving feature.
