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.

CityTouch: The Urban Lighting System Of The Future - The Pop-Up City - 1 views

    70% energy savings sound good. But how to claim 70% less maintenance costs. Less energy use means obviously less heat and more reliability. On the other hand, this is a much more complex system. It would be good to have an actual user stating this 70% reduction after installing the system and using it for a few years.

    San Jose will convert 115 lights to energy-efficient, programmable LED lamps by June 2009, and is seeking funds from the stimulus package to install additional lights and control systems. The plan is to change all of the city's more than 62,000 streetlights to a new system by 2022.

Nightclub Illuminated With 100% LED Light : MetaEfficient - 0 views

  • The Barcode nightclub was built in a disused brick Victorian railway arch in Vauxhall, south London. The entire nightclub is illuminated using only LED lights, and the sound system is also energy efficient. The architect, Woods Bagot claims that the system consumes “less electricity than the power used to boil a kettle”. If they could just give a watts per hour figure I’d be happier! Still, this is a interesting example of all-LED lighting in a building, which I’m sure we’ll see more in the coming years. Because the LEDs give off very little heat, much less AC is required to cool the building in summer. See more pictures over the fold.

Inflatable Solar Arrays Cost Up To 25X Less - 0 views

  • Also the solar units are so light weight that they can be suspended on steel cable lines rather than each having their own base connected to the ground. This rigging system allows for minimal land use disruption, 60 times less steel material and faster installation. The cables double as a control mechanism to align the units toward the sun.

Geoengineering could dim lights on solar power - environment - 23 April 2009 - New Scie... - 0 views

  •  
    PUMPING aerosol particles into the atmosphere to create a sunshade could take a heavier toll on solar power generation than expected. For every 1 per cent of the sun's rays deflected into space, the average output of solar systems that rely on direct sunlight would drop by 4 to 5 per cent, says Daniel Murphy at the US National Oceanic and Atmospheric Administration in Boulder, Colorado. Geoengineers propose scattering 1 to 2 per cent of sunlight.

Economic viability of small to medium-sized reactors deployed in future European energy... - 2 views

  • Future plans for energy production in the European Union as well as other locations call for a high penetration of renewable technologies (20% by 2020, and higher after 2020). The remaining energy requirements will be met by fossil fuels and nuclear energy. Smaller, less-capital intensive nuclear reactors are emerging as an alternative to fossil fuel and large nuclear systems. Approximately 50 small (<300 MWe) to medium-sized (<700 MWe) reactors (SMRs) concepts are being pursued for use in electricity and cogeneration (combined heat and power) markets. However, many of the SMRs are at the early design stage and full data needed for economic analysis or market assessment is not yet available. Therefore, the purpose of this study is to develop “target cost” estimates for reactors deployed in a range of competitive market situations (electricity prices ranging from 45–150 €/MWh). Parametric analysis was used to develop a cost breakdown for reactors that can compete against future natural gas and coal (with/without carbon capture) and large nuclear systems. Sensitivity analysis was performed to understand the impacts on competitiveness from key cost variables. This study suggests that SMRs may effectively compete in future electricity markets if their capital costs are controlled, favorable financing is obtained, and reactor capacity factors match those of current light water reactors. This methodology can be extended to cogeneration markets supporting a range of process heat applications.

First Commercial Wireless Electricity Experiment in Japan - 0 views

  • The nighttime experiment is meant to Illuminate the top spire of the mammoth steel structure to demmonstrate the use of the first wireless electricity transfer system in the World. The test is designed to transfer about 1200 watts of power at a range of 100 feet and will be a first of its kind use of a system Japanese scientists are developing to transmit power at distances they hope could reach 300 feet using a science that is based on magnetically coupled resonance.

Technology Review: Water-Activated Generator - 0 views

  • Hydrogen fuel cells may be decades away from widespread use in cars, but later this year, consumers will be able to buy a fuel-cell generator that's light and compact enough to grab off a shelf during a blackout--or even take on a backpacking trip. The 22-­centimeter-tall generator weighs about two kilograms with an unactivated fuel cartridge. Add water, plug in a device, and the system pumps sodium borohydride solution over a catalyst, freeing hydrogen to power the cell.

  • n 2010, thermal energy displaced hydro as the major source of energy generation for the Chilean Central Interconnected System.  Coal, natural gas, and diesel supplied over 50% of energy consumed while hydropower accounted for 48%.  This trend is expected to continue in 2011 if current water shortage conditions persist. (El Mercurio, 1/4/11)  Last year’s drought created a 26% increase in thermal generation as compared to 2009.
  • The Regional Energy Efficiency Strategy initiative led by Bun-ca has reported an energy savings of 9368 MWh over the past six years, equivalent to 4992 tons of carbon dioxide, by working with 190 companies in the industrial and commercial sectors to become more energy efficient.   Recently UNEP’s En.lighten study estimated that Costa Rica could save 276,000 MWh and $27.6 million per year if they changed all light bulbs to CFLs.  The cost of this change was estimated to be $22.63 million.  (El Financiero CR, 1/3/11)

UL Environment To Test Consumer Tech Energy Efficiency Claims | EarthTechling - 1 views

  • This new certification program, according to UL Environment, will be called Energy Efficiency Certification (EEC). It will test consumer focused items, including appliances, heating, air conditioning and refrigeration systems, high tech equipment, and lighting products, against energy efficiency standards and regulations like Energy Star, Natural Resources Canada (NRCan) and California Energy Commission (CEC). Those products which are proven to meet these standards will get yet another shiny label to put on product packaging – UL Environment’s leaf encapsulating the familiar “UL” initials and including the words “Energy Verified” in black text.
