Elevated greenhouse gas levels and a string of particularly destructive storms have created new interest in ways to reduce impacts on the world\u2019s environment and slow climate change.\u003C\/p\u003E\u003Cp\u003EAt the Georgia Institute of Technology, young companies arising from the Institute\u2019s $500 million-per-year research program are developing cleaner, more-sustainable technologies. Focusing mainly on cleaner production or more efficient use of energy, these ventures are converting research discoveries into applications with broad benefits.\u003C\/p\u003E\u003Cp\u003E\u201cClean technologies have very significant environmental and economic promise,\u201d says Stephen Fleming, vice provost of Georgia Tech\u2019s Enterprise Innovation Institute, and director of its Commercialization Services Division. \u201cSeveral companies based on Georgia Tech research are producing clean-tech products today here in Georgia or are knocking at that door, and numerous others show real promise.\u201d\u003C\/p\u003E\u003Cp\u003ECommercialization Services identifies, evaluates and promotes Georgia Tech research discoveries that show commercial potential. Most such discoveries fall into two categories: those that may be licensed to established corporations, and those few \u2013 about one in 10 \u2013 that can provide foundations for new companies.\u003C\/p\u003E\u003Cp\u003EThe VentureLab program of the Georgia Research Alliance supports development of those companies through grants and other assistance that helps them get started. Here are some highlights of Georgia Tech\u2019s \u201cgreen\u201d companies:\u003C\/p\u003E\u003Ch3\u003E\u003Cstrong\u003ESuniva: High-Efficiency Crystalline-Silicon Photovoltaic Cells\u003C\/strong\u003E\u003C\/h3\u003E\u003Cp\u003ESuniva Inc. began manufacturing high-efficiency crystalline-silicon photovoltaic cells in October 2008 at a 73,000-square-foot facility in Norcross, Ga. Suniva is the Southeast\u2019s first maker of solar cells, and it has plans to expand quickly.\u003C\/p\u003E\u003Cp\u003EUsing technology based on the research of Georgia Tech Regents\u2019 professor Ajeet Rohatgi, the company is presently manufacturing its ARTisun\u2122 solar cells at a rate of 32 megawatts (MW) annually \u2013 which would produce enough electricity to supply about 6,300 homes, Rohatgi says.\u003C\/p\u003E\u003Cp\u003ESuniva plans to triple its annual output to nearly 100 MW. The company currently employs about 70 people and expects to add more staff as it grows.\u003C\/p\u003E\u003Cp\u003ESuniva uses a patented technology it calls Star\u2122 to extract maximum performance from wafers of mono-crystalline silicon, a material often used for solar power generation.\u003C\/p\u003E\u003Cp\u003EA solar cell contains several layers, and every layer plays a role in the cell\u2019s overall efficiency. Rohatgi has studied solar cells in depth for some 30 years, learning how to optimize each layer to get maximum output \u2013 at the least cost.\u003C\/p\u003E\u003Cp\u003E\u201cWe want to be right at the sweet spot,\u201d explains Rohatgi, who is both Suniva\u2019s founder and chief technology officer. \u201cWe want cells that are highly efficient but low in cost, and that can generate power at a cost comparable to the power you buy from the electric company.\u201d\u003C\/p\u003E\u003Cp\u003ERohatgi\u2019s solar-cell research has received significant funding over many years from the U.S. Department of Energy.\u003C\/p\u003E\u003Cp\u003E\u201cSuniva is a shining example of how government support for research can lead to very real job creation,\u201d notes Robert Knotts, director of federal relations for Georgia Tech. \u201cIt\u2019s a strong reminder of why we should invest in research.\u201d\u003C\/p\u003E\u003Cp\u003ESuniva\u2019s current solar-cell output falls in the 17- to 18-percent efficiency range, which Rohatgi classifies as high, especially among lower-cost cells. But the company is continuing to improve its technology, and recently the National Renewable Energy Laboratory certified a new Suniva cell and cell structure at 20 percent efficiency.\u003C\/p\u003E\u003Cp\u003ESuniva is a graduate of Georgia Tech\u2019s Commercialization Services, which evaluates the commercial potential of technology developed at Georgia Tech and helps faculty members and other research staff form companies based on their research. In early 2008, Suniva joined the Advanced Technology Development Center (ATDC), Georgia Tech\u2019s science and technology incubator. It graduated from that program in April 2009.\u003C\/p\u003E\u003Cp\u003ETo date, Suniva has received total funding of $55.5 million from several venture capital organizations, including Menlo Park, Calif.-based New Enterprise Associates (NEA). Even more significant, Suniva now has contracts worth more than $1 billion through 2013.\u003C\/p\u003E\u003Cp\u003ERohatgi, who runs the University Center of Excellence for Photovoltaic Research and Education in Georgia Tech\u2019s School of Electrical and Computer Engineering, gained one important advantage early on: first-class management.\u003C\/p\u003E\u003Cp\u003E\u201cWith the help of NEA and Commercialization Services, Suniva has assembled a great management team with enormous experience in running technology manufacturing companies,\u201d he says. \u201cBeing able to put together such a well-established team played a big role in my decision to start the company.\u201d\u003C\/p\u003E\u003Cp\u003ESuniva\u2019s chairman and CEO, John W. Baumstark, is a technology-industry veteran with wide experience that includes serving as CEO of DWL before its acquisition by IBM and as chief operating officer of TRADEX Technologies before and during its acquisition by Ariba Inc. for $5.6 billion in 2000.\u003C\/p\u003E\u003Cp\u003EThe company\u2019s vice president of manufacturing, Stephen P. Shea, ran BP Solar\u2019s manufacturing line for many years. Daniel L. Meier, vice president of research and development, has worked for the National Renewable Energy Laboratory and has managed R\u0026amp;D for two other companies.\u003C\/p\u003E\u003Cp\u003E\u201cIn the next two to three years, we expect the quality-price balance of our product will put us at grid parity at a dollar per watt,\u201d Baumstark says. That means power from Suniva cells would cost about the same as buying power from an electric company.\u003C\/p\u003E\u003Ch3\u003E\u003Cstrong\u003EClimate Forecast Applications Network: Long-Range Weather and Climate Forecasts\u003C\/strong\u003E\u003C\/h3\u003E\u003Cp\u003EClimate Forecast Applications Network (CFAN) is using cutting-edge computer models to develop weather and climate forecasts on time scales from days to decades. The three-year-old company caters to clients needing forecast products beyond the traditional five-day forecasts provided by the National Weather Service, such as energy and insurance companies.\u003C\/p\u003E\u003Cp\u003ECFAN\u2019s capabilities include proprietary extended-range hurricane forecasting. They\u2019ve been providing this service for an energy-sector company for two years. CFAN\u2019s forecasts help that company manage both its energy-production and energy-trading activities in advance of a storm.\u003C\/p\u003E\u003Cp\u003ELast summer, CFAN correctly informed this energy-sector client that Hurricane Ike would strike Houston directly. What\u2019s more, CFAN did so a week before the storm hit land, several days ahead of other forecasters.\u003C\/p\u003E\u003Cp\u003E\u201cOur clients took a direct hit on this one,\u201d says Judith Curry, professor and chair of the Georgia Tech School of Earth and Atmospheric Sciences and a CFAN principal. \u201cThey used our forecasts for all their storm-related logistics, including evacuation.\u201d\u003C\/p\u003E\u003Cp\u003ECompanies in the retail sector also have a strong stake in accurate hurricane forecasts, she explains. For example, building supply companies want to move plywood and other materials to the correct hurricane target area. Sending it to the wrong spot can mean a financial loss.\u003C\/p\u003E\u003Cp\u003EOther CFAN clients include the insurance sector, which wants weather models that anticipate storm and flooding risks over the next 10 to 30 years. Insurance companies seek such data, Curry says, because they believe that ongoing climate change will alter future weather patterns.\u003C\/p\u003E\u003Cp\u003ECFAN\u2019s secret?\u003C\/p\u003E\u003Cp\u003E\u201cLet\u2019s just say we have a proprietary multi-model statistical dynamical method that includes European weather models,\u201d says Peter J. Webster, a School of Earth and Atmospheric Science professor who is also a CFAN principal. \u201cWe give a customized forecast product to each client. They come to us with a particular problem requiring particular forecasting, and we come up with a product just for them.\u201d\u003C\/p\u003E\u003Cp\u003ELike most Georgia Tech companies, CFAN has its roots in a research project. Webster was developing flood forecasts for the Asian Disaster Preparedness Center, an organization that works to prevent loss of life from storm-related flooding in such vulnerable countries as Bangladesh.\u003C\/p\u003E\u003Cp\u003EThat work brought the team to the attention of Ben Hill, a technology advisor for Georgia Tech Commercialization Services. He told them their research might have the right stuff to be the basis of a new company.\u003C\/p\u003E\u003Cp\u003EToday CFAN has a scientific staff of eight, income approaching seven figures and good prospects.\u003C\/p\u003E\u003Cp\u003EThe company has also worked with the World Bank, helping the Caribbean adapt to climate change. At issue: finding ways for those regions to deal with rising sea levels, more hurricanes and less rainfall.\u003C\/p\u003E\u003Cp\u003ESays Curry: \u201cThe whole issue of climate services is becoming potentially a growth area as companies, resources managers and agencies grapple with climate variability and change.\u201d\u003C\/p\u003E\u003Ch3\u003E\u003Cstrong\u003ERideCell: Making Existing Urban Transportation More Efficient\u003C\/strong\u003E\u003C\/h3\u003E\u003Cp\u003ERideCell aims to make existing urban transportation more efficient by making it more accessible.\u003C\/p\u003E\u003Cp\u003EThis young company covers both the private and public sides of the street. It uses technology that\u2019s already in the hands of millions \u2013 mobile phones and global positioning system (GPS) chips \u2013 to offer on-demand car pooling that\u2019s safe as well as flexible. It can also supply mobile-phone users with the kind of information \u2013 including schedules and actual in-route arrival times \u2013 that increases the usability of public transit systems like MARTA and localized systems such as Georgia Tech\u2019s Stinger buses.\u003C\/p\u003E\u003Cp\u003E\u201cThink of it as accessing all modes of transit via your mobile phone, in real time,\u201d says RideCell CEO Dave Kaufman. \u201cWe want to make car pooling, van pooling and MARTA much more attractive and reliable options than they are now.\u201d\u003C\/p\u003E\u003Cp\u003EIn today\u2019s Atlanta, he explains, 71 percent of people ride in single-occupancy vehicles, while only 10 percent of 2.5 million commuters car pool. The top reason that people continue using their private vehicles is flexibility. If they need to work late, or leave early to pick up a sick child, they don\u2019t want to be tied to a car pooling schedule.\u003C\/p\u003E\u003Cp\u003ERideCell\u2019s service, based on technology developed by Stephen L. Dickerson, an emeritus professor in the School of Mechanical Engineering, can make car pooling almost as convenient as that personal car, says company chief technology officer Aarjav Trivedi. A user can input travel time, destination and other preferences into a RideCell-enabled mobile phone, then watch as the system shoots back a range of ride options that offers smoking and even gender-preference choices.\u003C\/p\u003E\u003Cp\u003EThe first concern people raise for a system like this involves security, Trivedi acknowledges.\u003C\/p\u003E\u003Cp\u003E\u201cIt\u2019s not as simple as just matching people up \u2013 developing trust is key,\u201d he says. \u201cEveryone wants to be sure the ride they\u2019re getting is a safe one.\u201d\u003Cbr \/\u003ERideCell\u2019s solution, he says, is \u201climited networks of trust\u201d based on existing social networks. A corporate or university directory would represent one such existing network. Georgia Tech faculty and staff, for example, could agree to ride with other Georgia Tech employees.\u003C\/p\u003E\u003Cp\u003EA multi-layered registration process would ensure that only bona fide staff would find their way into the RideCell system. Various kinds of vehicle and\/or driver identification, from license-plate numbers and online photos to on-vehicle decals, might heighten security.\u003C\/p\u003E\u003Cp\u003ERideCell even uses the mobile phone\u2019s Bluetooth capability to automate authentication between driver and rider. And GPS-tracking technology could detect when a vehicle went off course, which might signal trouble.\u003C\/p\u003E\u003Cp\u003EOnce established, individual networks of trust could combine forces. For example, Georgia Tech employees could agree to share ride information with employees from nearby Coca-Cola.\u003C\/p\u003E\u003Cp\u003ERideCell is still working on its software, and not every mobile phone can host the company\u2019s system \u2013 although text messaging enables coverage of most of the mobile market. In addition, RideCell has made its product available to in-car GPS platforms including Dash Express.\u003C\/p\u003E\u003Cp\u003ERideCell\u2019s software even includes an integrated-billing function. The system adjusts subscriber accounts for transportation in either private vehicles or van pools \u2013 riders get billed, drivers get a credit.\u003C\/p\u003E\u003Cp\u003E\u201cAnd that\u2019s just the beginning,\u201d says company founder Dickerson. \u201cThis technology can be extended to high-occupancy toll lanes and even traffic metering, which could save billions in infrastructure build-out.\u201d\u003C\/p\u003E\u003Cp\u003ERideCell is already moving into the real world of convenient car pooling. The company is setting up a system trial involving some 150 Georgia Tech faculty, students and staff. It\u2019s hoped that the trial, performed in cooperation with Georgia Tech Parking and Transportation, will help iron out software glitches and provide a major step toward wider deployment.\u003C\/p\u003E\u003Cp\u003EWhy would people give up their beloved private vehicles to car pool or take MARTA?\u003C\/p\u003E\u003Cp\u003ETrivedi says there are several motivations. One is that gasoline prices can be expected to go back up \u2013 maybe not tomorrow but soon. A second is that \u201cmany people really do want to be green.\u201d A third is that some want to limit wear and tear on their cars \u2013 or avoid having to own a car at all.\u003C\/p\u003E\u003Cp\u003E\u201cAnd some people simply like riding with other people,\u201d he adds.\u003C\/p\u003E\u003Ch3\u003E\u003Cstrong\u003EQoil: Getting the Most Service from Motor Oil \u0026amp; Protecting Engines\u003C\/strong\u003E\u003C\/h3\u003E\u003Cp\u003EMany ventures aim to conserve oil, but few specifically target engine oil.\u003C\/p\u003E\u003Cp\u003EQoil uses a patent-pending electrochemical sensor to continually evaluate the condition of lubricating oil. Its technology can provide data on not only the motor oil but also on the engine it\u2019s protecting.\u003C\/p\u003E\u003Cp\u003E\u201cHistorically, it\u2019s been cheaper just to change your oil every 3,000 miles than to take a chance on damaging your engine,\u201d says Frank Mess, CEO of Qoil (pronounced \u201ccoil\u201d). \u201cThe net result is that hundreds of millions of barrels of oil or more are wasted every year as perfectly good motor oil is thrown out.\u201d\u003C\/p\u003E\u003Cp\u003ECurrently, he explains, vehicle-fleet owners who want to evaluate engine oil must have samples extracted and sent to a lab. It\u2019s a bit like what diabetics had to go through before portable blood testing equipment, he says. It\u2019s laborious, and periodic lab results are generally a poor substitute for on-the-spot information.\u003C\/p\u003E\u003Cp\u003EQoil\u2019s technology provides real-time electrochemical analysis of engine oil by placing sensors in the oil flow. The result is that owners can extract maximum life from their increasingly expensive motor oil. And, by monitoring for early signs of engine damage, the Qoil approach can help head off expensive repairs.\u003C\/p\u003E\u003Cp\u003EBased on the research of Steven Danyluk, the Morris M. Bryan Jr. Chair in Mechanical Engineering for Advanced Manufacturing Systems at Georgia Tech, Qoil\u2019s sensors initially make the most sense for fleet vehicles, Mess says. But private vehicles could also benefit as the technology becomes more widespread and affordable. The company is also working with potential customers in other industrial segments who need to protect high-value engines and gearboxes.\u003C\/p\u003E\u003Cp\u003EQoil now has 24 prototype oil-monitoring systems operational on commercial vehicles in the field. These installations use a bypass flow loop, in which oil flows past the sensor and back into the engine. Ultimately, Mess says, the sensor will likely be threaded straight into an engine port.\u003C\/p\u003E\u003Cp\u003ESignals from the sensor are processed and transmitted to Qoil\u2019s analysis system in Atlanta, where the company uses internally developed algorithms to analyze the data and produce detailed reports on oil and engine health.\u003C\/p\u003E\u003Cp\u003E\u201cWe\u2019ve had significant success in monitoring the chemical degradation of the oil as a function of time, as well as successes in detecting early failure symptoms that prevented expensive equipment failures,\u201d Mess says.\u003C\/p\u003E\u003Cp\u003EIn addition to VentureLab seed funding, Qoil has received a first round of venture capital. Qoil sensors are currently being manufactured in-house, but the company has engaged external partners as it prepares to ramp up production.\u003C\/p\u003E\u003Cp\u003EThe company is a member of the Advanced Technology Development Center (ATDC).\u003C\/p\u003E\u003Cp\u003EOther companies growing at Georgia Tech include:\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EVehicle Monitoring Technology\u003C\/strong\u003E\u0026nbsp;(VMT) monitors vehicle activity and vehicle emissions in conjunction with driver behavior to promote safety, better air quality and energy efficiency.
