Gov’t Will Allow Mainland Chinese Investments in LED and Solar Cell

Středa, Březen 21st, 2012

The Ministry of Economic Affairs (MOEA) will announce today (March 20) third-wave opening for mainland Chinese investments in Taiwan, which will include 115 manufacturing items, notably LED (light emitting diode) and solar cell, and 23 items for the service sector and infrastructure each.

At the Legislative Yuan, Economics Minister Shih Yen-shiang pointed out yesterday that for buying into domestic firms in key hi-tech industries, Chinese investors cannot become the controlling shareholder or the largest shareholder. In addition, the investment projects must contain industrial cooperation and must be subject to the inspection of an ad hoc panel.

Shih noted that the requirement will be more flexible than the existing ceiling of 10% stake owned by Chinese investors in existing enterprises and stricter than the 50% ceiling in new joint ventures.

The third-wave opening for mainland Chinese investments has been approved by the Executive Yuan (the Cabinet) and is scheduled to take effect by the end of March. Thanks to the three waves of opening, mainland Chinese investors will be able to invest in 97% manufacturing items, with the forbidden items including high polluting and nuclear safety businesses. Meanwhile, shares of service industry and infrastructure opened to Chinese investors will both reach 51%. In the third-wave opening, the government, for instance, allows mainland Chinese investments in mass rapid transit system and light-rail system.

Shih stressed that the restrictions on mainland Chinese investments are still much higher than other foreign investors but the difference cannot be too high, since mainland China is also a member of the World Trade Organization.

Since the government opened mainland Chinese investments in Taiwan in June 2009, mainlanders have invested US$272 million, creating some 5,000 job vacancies.

Pay-As-You-Go Solar Could Provide Clean Electricity to 1 Billion People

Čtvrtek, Leden 19th, 2012

Up to 1 billion people in the world still lack or have unsteady access to electricity. For these people, kerosene, a dirty petroleum product, is usually the fuel of choice–or more accurately, they have no choice. This US$36 billion a year industry often consumes 30 to 35 percent of poor families’ income.

Nevertheless there is hope – without giving Westerners the willies that we are going to kill the planet through carbon emissions. Solar energy, specifically solar printing, could be an answer. One company working on this front is Eight19, a UK company that provides printed plastic solar cells that are flexible, lightweight and can be used on a bevy of solar-powered applications.

Eight19 confronts the problem that the world’s poor face when choosing a fuel. While kerosene is relatively expensive, families are accustomed to purchasing the necessary fuel on an as-needed basis. Meanwhile clean energy options like solar power systems require payment up front.

IndiGo, Eight19’s pay-as-you-go solar power system, combines mobile telephone technology to provide pay-as-you-go solar. Users benefit from a unit that can light two rooms, and buy mobile phone credits that can then provide light for children’s homework at night or street vendors the ability to work when it is dark. The system is also scalable and can expand to cover more rooms if required by users. This high tech social innovation scheme provides countless opportunities at many levels.

Now, this social enterprise will ramp up its efforts with Solar Aid’s SunnyMoney, a solar lamp distributor in East Africa, through what they call the “Kickstart Sustainable Energy Fund.” Donations and interest-free loans from donors and impact investors will cover the first 4000 lighting systems to be installed in Kenya later this year.

If the program progresses smoothly, the circulating revenues that it generates should be one step in broadening solar lighting (and the all-important) mobile telephone recharging throughout the region.

Eight19 announced a Kickstarter campaign this week at the World Future Energy Summit in Abu Dhabi, United Arab Emirates. With countries like the UAE taking a more active role and providing more international aid, this is one such solution that can offer countless bang for the buck . . . or the dirham. From the Middle East to Latin America, solar as a service could build wealth and clean the local air–and boost countries’ goals to achieve increased energy independence.

Light sculpture to add new luster to Bay Bridge

Středa, Prosinec 14th, 2011

A pioneering artist plans to turn the western span of the Bay Bridge into the region’s biggest light sculpture with 25,000 bulbs flickering from its cables in sequences inspired by ebbs and flows of the Bay environment.

Leo Villareal, who has exhibited light sculptures at the National Gallery of Art and other major museums, already has mapped out a framework for computer software to operate his network of LED lights.

The project needs approval from Caltrans, but the toughest challenge could be raising $7 million in private donations needed for the project. Arts supporters on Tuesday kicked off a fund raising drive, saying they hope to start the four-month-long light installation in spring, and keep the sculpture lighted at night for two years.

The 25,000 white lights will shine, flicker and dim in sequences controlled by software Villareal is writing to reflect the moods and personality of the Bay.

“The bridge has inspired me,” he said. “This project is an outgrowth over talks about how to celebrate the 75th anniversary of the bridge this year.”

Villareal said he wants his light sculpture to enhance and amplify the natural beauty of the bridge architecture and the motions of the traffic on the structure and the wind, water and waves around it.

“These are not like Las Vegas lights where you go ‘I recognize that shape.’ It’s abstract,” Villareal, a New York-based artist, said Tuesday in San Francisco. “My main interest is to create a focal point for the community that is an experience that everyone can share, that will highlight this magnificent location, and bring something new to it.”

Before work can begin, Caltrans must grant permits ensuring that the lights won’t damage the bridge, block traffic, or disrupt drivers with distractions

“From what we have seen, it appears they will be able to meet those requirements,” said Caltrans spokesman Bart Ney. “This is a very detailed and serious plan.”

The 1-inch LED lights will be placed on the outside of bridge cables so they won’t be visible to bridge drivers and distract them, Ney said.

Laborers secured by harnesses will attach the lights to bridge cables at night to minimize disruptions to the 280,000 vehicles a day that cross the bridge, he added.

Caltrans has a program to consider proposed public art programs on soundwalls and other structures, but nothing of this scope has been proposed on a bridge, Ney said.

A necklace of lights was installed across the Bay Bridge in the 1980s, but it is permanent, unlike the light sculpture that will be removed after two years, said Ben Davis of the nonprofit Illuminate the Arts. one of the key light sculpture organizers.

Villareal, who lived in the Bay Area from 1994 to 1997, agreed to take on the project and develop the software to control the timing, sequence and intensity for each of the LED bulbs.

The development of the low-energy LED lights has made it practical to do large scale light sculptures that consume only a few dollars per day of energy, Villareal said.

An Efficient Holiday Season: Decorating Edition

Úterý, Prosinec 13th, 2011

Over the last couple weeks, I’ve shared with you some tips and tricks for minimizing the energy impact of your holiday cooking exploits and your shopping and gift giving activities. However, I’ve not yet touched on the aesthetics of the season.

No winter season is complete without the ornamental lights, or the cheerful air of holiday scents and decorations inside and outside your home. So today I’m going to share with you a few ways that you might be able to save some energy this holiday season, while still being able to make your home bright and festive for those relatives and guests you’re looking forward to entertaining.

When putting up lights, choose more efficient holiday lighting options.  The other day, John Wilson, SACE’s Research Director, shared with you his experience with LED lighting options for the home. In addition to using LEDs for everyday use, however, you can also switch over to more efficient LEDs light strings for your holiday decorating options.

According to Ameren Illinois, if all light strings purchased this year were Energy Star qualified, the electricity saved would equal that used by over 70,000 single-family households. Investing in LEDs can help you save money in the long-run too, since the bulbs or strings won’t need replacing every few years; one study by Consumer Reports stated that they had the same sets of LED lights burning for over 4,000 hours, without a single failure. And, you won’t have to waste hours searching for the one burnt out light bulb that’s keeping an entire string of lights from working properly.

Use timers on your lights so that you have less chores to worry about. It’s hard to remember to turn off outside lights at the right time, or turn off the tree when you aren’t going to be in the room. Putting timers on your holiday decorations will ensure that they aren’t using energy when there’s no one around to enjoy it. And, it will be one less thing you have to remember to do when you’re cleaning up after all the festivities.

Or, opt for non-electric decorations instead of lights. Traditional candles are just as beautiful as accent lighting, if not more so. Plus, if you’re a fan of scented candles, certain smells might be able to add just the right feel to your holiday festivities. Decorate your mantle with a few when guests are over, or light your walkway with them instead of using light strings; you’ll get that extra holiday glow, without that extra energy cost. Just make sure to pay attention to the flames, and follow your standard fire safety precautions.

For my sons, niece, and a couple of nephews — all of whom work long hours at a desk — I”m thinking of Home Depot’s three-way EcoSmart Soft White CFL. EcoSmart also offers an omni-directional LED bulb that casts a nice sharp light for reading. (A definite possibility for the business grad student poring over all those problem sets.)

For a niece who works in retail and needs to look good on the floor, I’m deciding between the EcoSmart G25, a 40-watt-equivalent, globe-type CFL bulb in soft white ($10 for two) and a standard halogen bulb.Halogens throw off light on the warmer end of the color spectrum and in all directions — qualities that work well in warm-hued bathroom settings.

Diodes, conductive thread illuminate textiles

Pondělí, Listopad 21st, 2011

Cheryl Sleboda of Plainfield, inserts light-emitting diodes (LEDs) into her whimsical fabric creations, sews them with conductive thread that resembles wire and buries microchips activated by her voice inside the quilt layers.

I met this fiber artist — she literally lights up when she quilts — during a recent trip to the International Quilt Festival in Houston.

Her profession in the comic book industry influences her fanciful quilt designs.

She has a series of fabric Artist Trading Cards, sized like baseball cards at 2.5 inches by 3.5 inches, that feature a cupcake with a flickering candle, a twinkling spaceship and a tiny zombie with one beaming eye.

These works are possible with a 20mm coin cell battery sewn on the back with conductive thread.

“Zombies are really popular right now,” Sleboda says.

These little guys, such as one she named Bummer, come to life through a hidden light component, a pin switch and conductive fabric layers wrapped around batting.

When you poke the doll with a pin in his sewn-on heart, the pin connects the circuit and illuminates his one eye.

On her website, Sleboda demonstrates the voodoo doll technique in a video and sells a starter LED kit for $15. The kit includes a bonus design for a zombie quiltlet.

“LEDs don’t get hot, so they won’t scorch fabric,” she says.

“Electroluminescent wire is flexible, and it can easily be cut and sewn for interactive textiles.”

Sleboda also works with other “smart materials” such as thermochromic paint that reacts to external stimuli.

Microchips inside some of her quilts are programmed so they light up in specific patterns. One microchip activated by voice flashes its lights more frequently inside the fabric layers when Sleboda talks near it.

“It can also pick up music” and flash in rhythm, Sleboda explains.

Her enthusiasm is as luminous in her smile as the high-tech materials that power her creations.

Other examples of her e-textiles are 8-inch-square renditions of a neon scientist working in his lab, gleaming with electroluminescent wire, and a “Lonely Hearts” robot quilt whose little heart shines via an LED bulb.

Her inspiration comes from cutting-edge fashion students who are incorporating such technology in clothing design to elicit unusual reactions from viewers.

At the Houston show, Sleboda’s larger quilt, “Road to Home,” was part of a special exhibit titled “Tactile Architecture.”

It, however, does not feature lights “because the battery power won’t last” long enough.

“I’m trying to figure out how to enter these types of (luminous) quilts into shows, so I need to come up with another way of powering them for exhibition,” she says.
