Live Performance and Special Events

Friday, June 18th, 2010

Most of my work tends to be in the realm of Opera, Dance, and Theater. As such I usually work with variations on three kinds of lights: Lekos, PARs, and Fresnels. These are fine lights and you can do quite a lot with them, but you can not do everything.

I am lighting an event tomorrow that will include ambient lighting of a large courtyard and a dance floor. The lighting is a collaboration between me and a friend of mine veering towards large scale installation. It should be a fun event to work.

Doing special events lighting is a whole different ballgame than working in live performance. In this case, the technology is very different. Here we will be using a lot of LED moving head fixtures and several effects projectors.

Not only is the technology different, but the style of working an event like this is much more on the fly than most of the work I do. At the same time, there are similarities which parallel these two worlds. For a play I might send my drawings off weeks before I have seen a single rehearsal. As such I have to plan out not only everything I intend to do regarding lighting the show, but I have to build in flexibility so that quick changes and alterations can be made in the very limited time available to us in tech. For tomorrow’s event, we met at the shop and talked through what equipment we would place where and combine how and so forth. With a few moments of “Oh let’s turn that on and see what it does.”

The event is at a church with some very nice architecture that should take light beautifully. In addition to lighting several rooms, we will light a large exterior stone wall with various colors and textures. Some of the ideas are about accenting architectural elements, while others are about transforming them. I remember a wedding I lit several years ago at the Brooklyn library. A less than aesthetically pleasing building inside, but quite impressive in scale. I had to transform the space with light in order to bring the qualities of the wedding into that not so romantic room.

Rather than being a carefully drawn out plot, we have a large pile of gear from which to draw. Certain ideas are very clearly formed, and several of the looks have been well thought through. At the same time, the event itself has a DIY ethic which means there could be any number of unexpected additions upon our arrival tomorrow. Because we do not necessarily know what we will be walking into, there has to be a certain amount of flexibility built into the lighting rig.

In some ways this is no different than live performance. I have had countless instances of scenery being built wrong, or me not receiving the final revision drawings, or the FOH positions being drawn in the wrong location on the house paperwork, or some other SNAFU which caused my well laid plans to get tossed to the side.

While there are some difference in terms of how the show or event gets prepped, the underlying skills remain the same. We must create a beautiful work of art that fulfills the project lead’s vision while making split second decisions under high pressure conditions in a very finite span of time.

Our work is not luxurious. We do not have time to sit around and wax poetic (a luxury I give myself in this blog precisely because it does not exist in the work). Rather we have a few seconds in which time to make a decision, see if it works, and change it if necessary. Time is too expensive to spend in anything other than the action of creating a more perfect work.

We are limited by time, and money, and resources, and personnel. The one thing we can not be limited by is creativity.

This is something that spans not only lighting designers, whether you light Opera, or parties, or store windows, but all designers. Our creativity is built around a deadline. We must produce. We have no other option. The doors will open when they are advertised to open. And we don’t have the luxury to not have created a beautiful product.

Solar Sunday is my weekly roundup of renewable energy and energy efficiency news from around the web.

Berkeley Goes Solar

Two Berkeley homeowners received checks for their new solar panels on Friday, becoming the first to flip the switch on the city’s much-ballyhooed, closely watched solar financing program.

“I’m a guinea pig, but there’s no way I could have afforded solar otherwise,” said Jeanne Pimentel, an editor who has 11 solar panels on her Allston Way home. “Because of this, I can help solve our energy problem without putting any money up front.”

Berkeley’s program allows property owners to pay for solar panels through a 20-year assessment on their property taxes. Pacific Gas and Electric Co. rebates and new tax breaks guaranteed in the federal stimulus package reduce the cost further, so most homeowners begin saving on electric bills immediately.

Twelve states, including New York, Washington and Colorado, and 50 California cities, including San Francisco and San Diego, are following Berkeley’s model and are closely watching how the program unfolds.

NYPD Hybridizes

Should you ever find yourself being pursued by the NYPD, now you can rest assured that the carbon footprint of your chase around the city will be just a little bit greener. As part of New York’s efforts to go green, the NYPD is rolling out 40 2009 Nissan Altima Hybrids for use during regular patrol. The vehicles get around 35 miles per gallon, which is about twice of the range of the current fleet of Chevy Impalas and Ford Crown Victorias.

More Solar Phones

Just last week we brought you news of the Blue-Earth, Samsung’s new solar powered touch phone. Well, it turns out that they are not the only company with solar dreams. Chinese mobile manufacturer ZTE recently revealed the Coral-200, a solar-powered handset with one very unique characteristic that sets it apart from its competitor: it will only cost 40 dollars!

Largescale Wind Power Proven Viable

Research by TU Delft proves that Dutch power stations are able to cope at any time in the future with variations in demand for electricity and supply of wind power, as long as use is made of up-to-date wind forecasts. PhD candidate Bart Ummels also demonstrates that there is no need for energy storage facilities. Ummels will receive his PhD on this topic on Thursday 26 February.

Wind is variable and can only partially be predicted. The large-scale use of wind power in the electricity system is therefore tricky. PhD candidate Bart Ummels MSc. investigated the consequences of using a substantial amount of wind power within the Dutch electricity system. He used simulation models, such as those developed by Dutch transmission system operator TenneT, to pinpoint potential problems (and solutions).

His results indicate that wind power requires greater flexibility from existing power stations. Sometimes larger reserves are needed, but more frequently power stations will have to decrease production in order to make room for wind-generated power. It is therefore essential to continually recalculate the commitment of power stations using the latest wind forecasts. This reduces potential forecast errors and enables wind power to be integrated more efficiently.

ETC goes LED

After long speculation about whether entertainment-lighting leader ETC would enter the LED market, the company has announced their acquisition of the Selador™ product line from Selador co-founders Rob Gerlach and Novella Smith.

“We didn’t want to make a ‘me too’ RGB or RGBA product that didn’t provide the kind of significant innovation in lighting we strive for,” says ETC CEO Fred Foster. “With its exclusive x7 Color System™, the Selador product line produces a far superior quality of color and light to anything that we had seen before in LEDs. We also benefit from the brainpower of Selador LED experts Novella and Rob – great people who will join our ETC team.”

The Sun turns CO2 into Fuel

Powered only by natural sunlight, an array of nanotubes is able to convert a mixture of carbon dioxide and water vapour into natural gas at unprecedented rates.

Such devices offer a new way to take carbon dioxide from the atmosphere and convert it into fuel or other chemicals to cut the effect of fossil fuel emissions on global climate, says Craig Grimes, from Pennsylvania State University, whose team came up with the device.

Although other research groups have developed methods for converting carbon dioxide into organic compounds like methane, often using titanium-dioxide nanoparticles as catalysts, they have needed ultraviolet light to power the reactions.

The researchers’ breakthrough has been to develop a method that works with the wider range of visible frequencies within sunlight.

Cell Phones Go Solar

Samsung Electronics Co. Ltd. recently unveiled its new, innovative solar powered full-touch screen phone, the “Blue Earth.” The Blue Earth phone is also part of “The Blue Earth Dream: Eco-living with SAMSUNG mobile,” an environmental initiative by the company to reduce its CO2 emissions, eliminate its use of hazardous substances and encourage cell phone recycling.

The phone is made from a recycled plastic prodct called PCM, which is made from water bottles. The packaging for Blue Earth is designed to be small and light, is made from recycled paper and comes with a 5-star energy efficient charger that uses standby power lower than 0.03W. The phone and charger are also free from harmful substances such as brominated flame retardants, beryllium and phthalates.

No Heating Required

Judd Blunk’s house is like a womb. Although the temperature outside is in the 20s, his triple-pane windows overlooking the Fox River feel warm from inside.

Because there is no furnace, the rooms are quiet. The only sound in the kitchen is the hum of a refrigerator, which along with other appliances, helps supply heat to the airtight 2,300-square-foot Batavia, Ill., home.

Blunk is part of a small movement of engineers and homeowners who are taking President Barack Obama’s vision of building energy-efficient homes to another level. They are inspired by “passive houses” in Germany that are so well-insulated and energy-efficient they eliminate the need for a conventional heating system.

Such design could be the future as Americans become more concerned with shrinking their carbon footprints and look at ways to avoid volatile energy prices.

Butterfly Effect

THE light-scattering structures that make butterfly wings so striking could be used to make cheaper, more efficient solar cells.

In dye-sensitised solar cells a dye coating on a titanium dioxide surface forms a “photoanode” that absorbs photons and pumps out electrons. To improve their efficiency, Di Zhang of Shanghai Jiao Tong University in China and colleagues borrowed the light-absorbing properties of the wings of the Paris peacock butterfly.

After soaking samples of the wing in a titanium-containing solution, they processed it to produce a titanium dioxide deposit that reproduced the wing’s honeycomb structure (Chemistry of Materials, DOI: 10.1021/cm702458p). When this was used to make a photoanode, the resulting cell’s efficiency was 10 per cent higher than normal.

Guess What Markets My Investment Money Is Going To

The election of Barack Obama has put the wind back into the sails of the renewable energy sector, where investor confidence had been badly punctured by the credit crisis. Clean technology and green energy stocks have soared as City analysts predict a major boost from the incoming president.

Solar Integrated Technologies rose by 30% yesterday after increases of 22% by Renewable Energy Corporation and 16% by the wind turbine maker Vestas in the 24 hours before, when they were helped upwards by oil prices returning to above $70 a barrel.

Obama has promised to invest $150bn over 10 years in renewables as part of a wider plan to increase US energy security amid fear of oil shortages, while also reducing the country’s carbon emissions in a bid to tackle global warming – and create jobs during an economic downturn.

LEDs Go Solar

Thanks to rapid improvements in photovoltaic and LED lighting technology, solar-powered LED lighting is now suitable for a range of illumination applications, according to Sean Bourquin and Anthony Tisot of Carmanah Technologies.

Against a climate of rising energy costs and escalating environmental concerns, today’s advanced LED technology is creating new opportunities in solar-powered area lighting. Thanks to a new generation of bright and efficient LEDs, solar-powered lighting is expanding from its role in signal lights and flashing beacons to offer a renewable energy alternative for general illumination applications.

Shrinking Solar

Some of the tiniest solar cells ever built have been successfully tested as a power source for even tinier microscopic machines. An article in the inaugural issue of the Journal of Renewable and Sustainable Energy (JRSE), published by the American Institute of Physics (AIP), describes an inch-long array of 20 of these cells — each one about a quarter the size of a lowercase “o” in a standard 12-point font.

The cells were made of an organic polymer and were joined together in an experiment aimed at proving their ability to power tiny devices that can be used to detect chemical leaks and for other applications, says Xiaomei Jiang, who led the research at the University of South Florida.

Traditional solar cells, such as the commercial type installed on rooftops, use a brittle backing made of silicon, the same sort of material upon which computer chips are built. By contrast, organic solar cells rely upon a polymer that has the same electrical properties of silicon wafers but can be dissolved and printed onto flexible material

Solar Gets More Efficient

No matter which way you look at it, the notion of harvesting energy from the sun to power our homes and businesses is more absorbing than ever.

Researchers at Rensselaer Polytechnic Institute have discovered and demonstrated a new method for overcoming two major hurdles facing solar energy. By developing a new antireflective coating that boosts the amount of sunlight captured by solar panels and allows those panels to absorb the entire solar spectrum from nearly any angle, the research team has moved academia and industry closer to realizing high-efficiency, cost-effective solar power.

“To get maximum efficiency when converting solar power into electricity, you want a solar panel that can absorb nearly every single photon of light, regardless of the sun’s position in the sky,” said Shawn-Yu Lin, professor of physics at Rensselaer and a member of the university’s Future Chips Constellation, who led the research project. “Our new antireflective coating makes this possible.”

Fungal Diesel

A unique fungus that makes diesel compounds has been discovered living in trees in the rainforest, according to a paper published in the November issue of Microbiology. The fungus is potentially a totally new source of green energy and scientists are now working to develop its fuel producing potential.

“This is the only organism that has ever been shown to produce such an important combination of fuel substances,” said Professor Gary Strobel from Montana State University. “The fungus can even make these diesel compounds from cellulose, which would make it a better source of biofuel than anything we use at the moment.”

The fungus, which has been named Gliocladium roseum, produces a number of different molecules made of hydrogen and carbon that are found in diesel. Because of this, the fuel it produces is called “myco-diesel”.

New Solar Cells Increase Efficiency

In the new study, researchers describe lab tests of solar cells made with a new type of ruthenium-based dye that helps boost the light-harvesting ability. The new cells showed efficiencies as high as 10 percent, a record for this type of solar cell. Most silicon-based solar cells have so-called efficiencies of around 12 percent. But manufacturing silicon is not cheap. The current cost of electricity from silicon-based solar panels for houses or businesses is 25 cents to 40 cents per kilowatt-hour, roughly triple what most people pay their utility company.

Introducing the Emergency Response Studio

After Hurricane Katrina, Paul Villinski, a well-known New York-based artist, wanted to transport his studio to Louisiana to see the aftermath first-hand and create artwork in response. At the time he didn’t have a way do it, but since then has picked up a 30′ trailer, gutted it, and rebuilt it to be green, non-toxic and off-grid. The Emergency Response Studio is now a totally self-sufficient traveling artist studio outfitted with solar panels, a wind turbine, non-toxic furnishings, and plenty of space to create.

[SNIP]

While this trailer was originally designed as an artist’s studio, it also serves as a model for off-grid mobile housing and emergency shelters. These trailers could even be transformed in a cost-effective manner if built or retrofitted in numbers. Villinski, who often takes empty aluminum cans and turns them into art, says that “In a sense this FEMA trailer is just a really big beer can I’m transforming into something of beauty.”

The Emergency Response Studio will be on exhibition in New Orleans starting November 1st for the Prospect .1 New Orleans show featuring contemporary art from international artists. The show aims to revitalize the city by establishing New Orleans as a center for contemporary art, showcasing historical architecture, exposing the people of New Orleans to new art, educating students, and developing a new tourism attraction for the city. The Emergency Response Studio will be stationed at various locations around the city until January 18th, 2009.

California Goes Solar

California’s first solar thermal plant in 20 years recently launched in Bakersfield, helping to usher the golden state into a new era of renewable energy. Designed by Ausra, the Kimberlina solar thermal plant will utilize 1,000-foot long mirrors to convert the sun’s rays into energy. The new plant is the first of it’s kind in North America and was constructed in just seven months.

Green Is Good For Health, And In Other News, The Sky Is Blue

Childhood obesity can lead to type 2 diabetes, asthma, hypertension, sleep apnea and emotional distress. Obese children and youth are likely to be obese as adults, experience more cardiovascular disease, high blood pressure and stroke and incur higher healthcare costs. In an article published in the December 2008 issue of the American Journal of Preventive Medicine, researchers report that children living in inner city neighborhoods with higher “greenness” experienced lower weight gains compared to those in areas with less green space.

Intel Invests In Solar

Shrugging off gloom over the economic outlook, Intel Capital on Tuesday announced its first “clean-tech” initiative in China, a $20 million equity investment in Trony Solar Holdings Co., one of China’s biggest makers of solar energy and wind power equipment.

No Drilling for Germany, Let’s Talk About Off-Shore Wind Farms

Germany opened its first offshore wind farm Tuesday which Environment Minister Sigmar Gabriel called a key step toward more reliance on renewable energy in Europe’s biggest economy.
Gabriel pressed the start button at the Hooksiel complex some 500 metres (500 yards) off Germany’s North Sea coast.

The five megawatts produced at the pilot site will flow into the gas and electrical station in the coastal city of Wilhelmshaven, enough to serve 5,000 households.

“Offshore wind power is of key importance for our future energy supply and a decisive factor in achieving our expansion goals for renewable energy,” Gabriel said.

Buddhists Go Green

The Wat Pa Maha Chedio Kaew temple has found a way to bottle-up Nirvana, literally. The temple, which sits in Thaisland’s Sisaket province, roughly 370 miles northeast of Bangkok is made of more than a million recycled glass bottles. True to its nickname, “Wat Lan Kuad” or “Temple of Million Bottles” features glass bottles throughout the premises of the temple, including the crematorium, surrounding shelters, and yes – even the toilets. There’s an estimated 1.5 million recycled bottles built into the temple, and as you might have guessed, they are committed to recycling more. After all, the more bottles they get, the more buildings they are able to construct.

Nano-Tech Goes Solar

In both cases, the idea is the same: use nanowires to more efficiently conduct electrons from the collection surface of the solar cell to an electrode. Contemporary thin-film solar cells provide no direct conduit for electron travel.

If the process scales well, it has the potential to dramatically improve the efficiency of next-generation solar photovoltaic panels.

“If nanowires are going to be used massively in photovoltaic devices, then the growth mechanism of nanowires on arbitrary metallic surfaces is an issue of great importance,” said Paul Yu, a professor at UC San Diego, and a member of the project team which published the nanowire research. “We contributed one approach to growing nanowires directly on metal.”

Green Improves Job Satisfaction

If employers want to increase job satisfaction, a little shrubbery apparently goes a long way. Workers are happier when offices have plants and windows, a new study found.

American office workers spend an average of 52 hours a week at their desks, according to the 2000 U.S. Census. Some might argue that not all that time is spent working, but still, all those hours in windowless offices with artificial light can take their toll.

A few green additions could have a large effect on worker happiness, according to the study led by Tina Cade, an associate professor of horticulture at Texas State University, and Andrea Dravigne of the San Marcos Nature Center.

“We pretty much found out that if you had windows and plants or even if you just had plants in your office, you were more satisfied with your job,” Cade told LiveScience. “We thought it was important for offices because a lot of times people are looking for ways to keep employees happy and do all these expensive things like put in a daycare or a workout room. Maybe for less investment they could put in a few plants in strategic places.”

Dirt Goes Green

Soils contain more than twice as much carbon as the atmosphere according to estimates (Food and Agriculture Association of the United Nations, FAO). Increasing the amount of carbon naturally stored in soils could provide the short-term bridge to reduce the impacts of increasing carbon emissions until low-carbon and sustainable technologies can be implemented. A group called Soil Carbon, based in Australia, makes the case for soil carbon storage in a presentation available in English, German, Spanish, Italian, Mexican and Portuguese. The Soil Carbon report includes impressive photographs, such as those above, demonstrating the difference between well-managed and poorly managed soils.

IBM Goes Solar

IBM has leveraged their computer-chip cooling know-how into a highly effective solar concentrator design. Bench-scale testing of the design (as pictured) shows an order of magnitude increase in solar power output from a unit cell. Other designers have worked out CPVs with similar concentrating lenses, typically paired with a tracking device. The cooling part of IBMs’ design is the cool part: something no other designer has access to, presumably.

Carbon Capture Cuts Costs

Maciej Radosz and his colleagues at UW decided to use activated carbon and other carbon-rich materials — much cheaper alternatives — to adsorb the CO2. While previous studies had suggested that high pressure conditions were needed for the carbon-rich materials to work effectively, Radosz intuited that separation could also occur under low pressure/temperature conditions — a gamble that paid off when he put it into practice.

The researchers are now working on scaling up the process and on making the carbon materials more selective; if successful, they believe it could drop the cost of CCS to $20 a ton, or less than half current prices.

Sony Goes Solar

Japanese electronics conglomerate Sony Corp (6758.T) said on Sunday it has developed dye-sensitized solar cells with an energy conversion efficiency of 10 percent, a level seen necessary for commercial use.

Dye-sensitized solar cells, which use photosensitive dye and do not require costly and large-scale production equipment, are seen as a promising next-generation solar cell variety and potential threat to silicon-based solar cells.

One small step for Micro$oft, one giant leap for OpenSource software

Microsoft was set to announce Thursday that it would make the interchangeable document format of a competitor available in its own market-leading Office 2007 software during the first half of 2009.

The company, under pressure from European regulators, national standards organizations and its own government clients, said it planned to give customers the ability to open, edit and save documents in Open Document Format — the main competitor to the Microsoft Word format — through a free update.

With the update, consumers will be able to save text documents in ODF format and adjust Office 2007 settings to automatically save documents in the rival format.

An old post WRT a new discussion

Saturday, May 3rd, 2008

With all the recent talk of “how theatre failed America” I thought I might repost something I wrote almost two years ago.

The original post is here.

Enjoy!

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Writer Warren Ellis created a series called The Global Frequency in which he posits the existence of a global network whose mission is to save the world from destruction. Rather than superheros who fly around in red capes, we find more or less ordinary citizens connected by cellphones and other wireless networks. Each person on ‘The Frequency’ is some kind of specialist in a given field. In the pilot to a now abandoned TV series based on the work, one of the people needed to prevent a major disaster is an olympic gymnast. Not your typical comic book character.

The point is that in a world with the networked potentials that we have today, limiting our activities to traditional notions of role and geography, be they crime fighting or artistic, is looking backwards. The Poor player, while being somewhat self deprecating, makes the important and necessary observation that we need to reorient our vision.

There has been a lot of talk in the last few days regarding Terry Teachout’s recent article. He points out that some of the best theatre being made in the US is occurring in regional theatres. Interestingly enough, this theatre is being made on the same model as The Global Frequency. That is, teams of artists are assembled from across the country, if not internationally, to create works for a localized community. A need is found within a given socio-geographic space, for a particular kind of work. The artists who can best manifest that work are brought together to create. These works in turn, if successful, often go on tour or end up as co-productions with other regional theatres.

This is an amazing feat and something made possible precisely because of modern technologies. The Looking Glass Theater in Chicago is one company that comes to mind when I think of this networked national theatre. I was fortunate enough to board-op their co-production of Metamorphoses with the Berkeley Repertory Theatre a number of years ago before it came to Broadway. As the show toured cast members would leave and new ones would be added in, so there was an interesting mixture of the original ensemble and local actors, one of whom I had worked with at Impact Theatre a year or so before.

There are local theater’s all across the US. This is the New York Off-Off-Broadway scene or the companies I have worked with in California, Impact and ERP among others. The Poor Player tells us of ones in Buffalo, NY. The regional theatre movement of the 1960′s and 1970′s broke the stranglehold on American Theatre that New York had and created a vital new model for producing works in this country. Even as the original intent of these institution evolved to be more national in scope, smaller companies crop up to take on the role of local theatre. But in our connected world it is not enough to simply call for isolationist tribalism. We must look at how to further connection and cross pollination between artists and communities. We must look forward, not just back at the past.

The voice of Duluth might live in Sacramento and the costume designer who understand her lives in Minneapolis. Unless there is a network, a Global Frequency, this artistic team might never find one another. Creating theatre is never so simple an issue as geography or even friendship. These things are important, but in the end it is about finding those people with whom you have a sympathetic artistic relationship and creating works that are vital and powerful. As I said yesterday it is important to look for ways to expand the network.

When I look at the US government I see an entity that is wholly out of touch with the modern world. Where everywhere else technology and ideology are breaking down traditional boundaries, through organizations like the EU and technologies like VOIP and social networking sites, the US Federal government is concerned with Sovereignty. They want to create physical barriers and psychological barriers between US and THEM. They want to reclaim a 19th century idea of the nation state complete with hard power dominance, while everywhere else energy is flowing towards a post-sovereign state influencing events through soft power. There is nothing wrong with history. I find it fascinating to read of events gone by. But it seems silly to me to try and force the energies of change into old fashioned models that do not sit harmoniously with the contemporary world.

But the old models of Self and identity are washing away with time. Be they national or personal, the individual is on the way out. A holistic organic model of self needs be explored. The connections between examined rather than boundaries.

The future is here. We need only reorient our vision and embrace its potential.

Solar Sunday is my weekly roundup of renewable energy and energy efficiency news from around the web.

MIT speeds up Solar Technology

Promising to transform solar power from a “boutique” option to an affordable, dependable, mainstream energy solution, MIT and the Chesonis Family Foundation today launched a “solar revolution” with the ultimate aim of making solar energy America’s primary carbon-free fuel.

The Solar Revolution Project (SRP), funded by a $10 million gift from the Foundation, will explore new materials and systems that could dramatically accelerate the availability of solar energy. The SRP will complement and interact closely with other large solar projects at MIT, creating one of the largest solar energy clusters at any research university.

The Chesonis gift will allow MIT to explore bold approaches that are essential for transforming the solar industry. Specifically, it will focus on three elements –capture, conversion and storage — that will ultimately make solar power a viable, near-term energy source.

“Solar is thought of as an ultimate energy technology off in the distant future. The goal of SRP is to move this timeframe nearer to the present. The SRP will make solar a practical alternative, by committing a 10-year timeframe for establishing the new base of scientific knowledge it will take to draw a market-competitive energy supply from the sun,” said Daniel Nocera, the Henry Dreyfus Professor of Energy and Professor of Chemistry at MIT, who will direct the SRP. “With SRP, think ‘solar’ and think ‘now.’ This is the revolution that is implied in the project name.”

Windows go Solar

The Queensland University of Technology recently announced that it has been working with Dyesol to develop an innovative solar cell technology that re-envisions windows as clear, clean energy providers. Professor John Bell has said that these dye-infused solar cells would significantly reduce building energy costs, and could even generate surplus energy to be stored or sold. The development has been touted as the most promising advance in solar cell technology since the invention of the silicon cell.

Modern architecture has a love-hate relationship with windows: they contribute light and levity to interior spaces, yet they are the most frequently cited culprits for thermal energy loss. Traditional approaches to the problem have tended towards increasing insular ability, however this new development would imbue windows with power producing capabilities, actually providing energy instead of leaking it.

Dyesol’s solar cells use an innovative technology called “artificial photosynthesis”, wherein a dye analogous to chlorophyll absorbs light to generate electricity. The panels are composed of “an electrolyte, a layer of titania (a pigment used in white paints and tooth paste), and ruthenium dye sandwiched between glass. Light striking the dye excites electrons which are absorbed by the titania to become an electric current.”

California goes Soalr

With California utilities expanding rapidly into renewables, the Mojave Desert is one of the hottest spots for solar energy. Last year, plans for the world’s largest solar array got underway in this ideal energy harvesting setting and the latest news is just as groundbreaking. Pacific Gas and Electric recently signed the world’s largest solar deal to date, teaming up with BrightSource Energy to produce three new solar-thermal electric plants for a whopping 500 megawatts of clean green power. The $2 to $3 billion dollar deal provides options for additional plants (up to 900 megawatts total), which would be enough to power 375,000 Californian homes!

California law currently requires PG&E to produce 20% of its power via renewable sources by 2010, which is one of the factors driving this deal. The energy giant has been hard at work signing contracts, diversifying its renewable portfolio to include solar, wind, biomass, geothermal, and hydroelectric sources. Fong Wan, vice president of energy procurement, states “Solar-thermal energy is an especially attractive renewable power source because it is available when needed most in California – during the peak mid-day summer period.”

Let’s go fly a Soalr Baloon

What could be more refreshing than casting off your carbon shackles with a bunch of solar balloons? Our favorite environmental architect visionary, Joseph Cory, of Geotectura has seized this dream with an award winning way to take solar energy to the skies. He’s teamed up with Technion aerospace engineer Dr. Pini Gurfil to develop an an array of helium filled platforms constructed from a new fabric coated with photovoltaic solar cells. Dubbed Sunhope, the project is showing great promise as a low-cost deployable system that would harness solar energy while maintaining a minuscule environmental footprint.

Luxim labs recently unveiled an incredibly energy efficient light bulb that packs more luminosity than a street lamp into a pill-sized form factor. Each bulb is filled with argon gas, which turns to plasma when electricity is focused through it. The energy is driven to the bulb without electrodes. The resulting light is intensely bright and mirrors the quality of light radiated by the sun, yet is produced by one of the smallest, most energy efficient light sources we’ve seen.

Luxim, Pill bulb, tiny pill light bulb plasma bulb, halodes, super bright light bulb, eco lighting, green lighting, sustainable lighting, energy efficient lighting, lumen, pill-sized plasma bulb, argon gas, super-bulb, LED, light bulb

A substantial portion of energy is converted into light instead of heat, which makes the bulbs highly efficient. Each super-bulb produces a stunning 140 lumens per watt, doubling the output of high-end LEDs (70 lumens per watt) and leaving standard light bulbs in the dust (15 lumens per watt). While cost and longevity have yet to be released, these brilliant bulbs represent a bright future for energy efficient lighting.
