Solar Energy Breakthrough at OSU - 0 views

  •  
    The Video Learning Center explains that conventional silicon solar cells operate by reacting with photons in light and create free electrons which flow as current in a circuit. But these electrons only remain free for a very short time. The material the OSU researchers created is not only able to capture all visible light, but also to free electrons for 7 million times longer than silicon. As a result more electricity is capable of being produced than ever before.

Light-emitting diode - Wikipedia, the free encyclopedia - 0 views

  • The LED is based on the semiconductor diode. When a diode is forward biased (switched on), electrons are able to recombine with holes within the device, releasing energy in the form of photons.
  •  
    A light-emitting diode (LED) (pronounced /ˌɛl.iːˈdiː/[1]) is a semiconductor light source. LEDs are used as indicator lamps in many devices, and are increasingly used for lighting. Introduced as a practical electronic component in 1962,[2] early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness.

Efficiency debate: The pros and cons of consumer electronics - 0 views

  •  
    The American Council for an Energy-Efficient Economy issued a report yesterday touting the role that semiconductor-based technologies have played in making the U.S. economy more efficient. At the same time, the International Energy Agency issued its own report calling on governments around the world to be more aggressive with efficiency standards for ICT and consumer electronics, which are expected to demand twice as much power by 2022 and three times as much by 2030 - creating a need for another 280 gigawatts of power generation (i.e. like adding another Japan to the world, or more than 230 nuclear reactors). "This will jeopardize efforts to increase energy security and reduce the emission of greenhouse gases," according to an IEA news brief.

A Bright Idea: Introducing ESL Light Bulbs from Vu1 - 2 views

  •  
    "start up company Vu1 is adding another light bulb option (not to mention acronym) to the mix, the Electron Stimulated Luminescence (ESL) bulb. The Vu1 ESL innovation re-purposes technology from our tried and true friend, the cathode ray tube (CRT) television. ESL uses accelerated electrons to stimulate phosphor and create light, thus making the bulb surface glow."

Jababeka Business: Piezoelectric motors save power and downsize electronic access control - 0 views

  • Designers looking to save power and size are turning to advanced technologies, and motors are no exception. With piezoelectric technology at the heart, a new type of motor is improving small-scale motion systems in a big way. Electronic access control enhances security, convenience, safety, and flexibility in a wide range of applications from building automation to automobiles. Today, system designers are adding "smallest size" to the requirements list for the electronic actuators at the core of access control systems.

Household Energy Use to Triple by 2030, Due to Power-Hungry Electronics - 0 views

  •  
    The IEA says in a new "Gigawatts and Gadgets" report that electricity consumption from power-hungry electronics could cause household energy use to triple by 2030. That means increased greenhouse gases from electric generation, and increased electric bills for creating that power.

Linux design targets 802.11n-enabled homes - 0 views

  •  
    This is a reference hardware design to add wireless capability to 'any' electronic consumer device. This is important because the availability of designs such as this will drive the networking path for smart homes. This is the first I have seen and it is wireless.

Technology Review: Silicon Nanocrystals for Superefficient Solar Cells - 0 views

  •  
    A typical solar cell generates only one electron per photon of incoming sunlight. Some exotic materials are thought to produce multiple electrons per photon, but for the first time, the same effect has been seen in silicon.

Large-scale dimmer switch company gets $9 million | CNET News.com - 0 views

  •  
    Metrolight, which has just received $9 million in a third round of funding from Gemini Israel Funds and Richard Branson's Virgin Fuels, has been riding a surge of demand for its high-frequency electronic ballast, a device for controlling high-intensity discharge (HID) lights--those bright lights used for illuminating department stores, large interior spaces and freeways. The system effectively provides the same amount of light as more traditional magnetic or electromagnetic systems, but requires less overall power, the company says. Additionally, the HID lights can be dimmed when no one is present or, if the light fixture is connected to the Internet, dimmed by a utility to prevent a brown-out. Some customers have seen their electric lighting and maintenance bills drop by around 50 percent, according to Metrolight.

GE: Smart grid yields net-zero energy home | Green Tech - CNET News - 0 views

  •  
    GE appliances have been converted to have electronic controls and will have a small module in the back that will allow it to communicate with a home's smart meter. With that communication link in place, consumers can find out how much electricity individual appliances use and program them to take advantage of off-peak rates.

Electronic Component Suppliers - Electricity Storage Association - electric utility, esco - 0 views

  • While capital cost is an important economic parameter, it should be realized that the total ownership cost (including the impact of equipment life and O&M costs) is a much more meaningful index for a complete economic analysis. For example, while the capital cost of lead-acid batteries is relatively low, they may not necessarily be the least expensive option for energy management (load leveling) due to their relatively short life for this type of application.

Could the Electric Grid Support Far More Wind and Solar? | Wired Science from Wired.com - 0 views

  • The commonly accepted wisdom in the energy industry is that the grid could only draw something like 20 percent of its power from wind and solar resources before encountering major reliability problems. But the new power flow simulation (.pdf), presented for the first time this week at the American Geophysical Union meeting, shows that, at least in California, the power grid might be able to handle three times that much renewable energy without encountering major trouble pushing electrons around the state.

Why can't solar cells pickup infrared? | Greenbang - 0 views

  •  
    "The new material provides a "stepping-stone" for electrons to move from one energy level to another as they absorb photons, allowing more photons of different energy levels (and thus different parts of the light spectrum) to be utilized. So while some efficiency research goes into breaking down what is absorbed into specific wavelengths or trapping light for greater absorption, this technology basically casts a really wide net in order to increase how much light can be captured and turned into energy."
