Sustainable Energy is a leading developer and manufacturer of power conversion products for the renewable energy industry. Power conversion is a critical element of clean power integration with electricity grids around the world. Highly intelligent power inverters are needed to efficiently convert the raw power generated by solar modules, small wind turbines, fuel cells, micro-turbines, and battery storage into high quality AC power that is useable in homes and businesses.

Sustainable Energy has developed and patented a unique technology that enables more efficient utilization of renewable energy assets. For Solar applications, the high efficiency at low operating voltages allows arrays to be wired in parallel, resulting in higher power output in real world conditions and substantially greater flexibility in designing building integrated PV systems. For wind power applications, our focus on developing rapid control response makes it possible to capture more power from every gust of wind.

In 2006, the Company launched its first commercial product and captured a large portion of the Spanish market with the Sunergy 5 inverter, setting a solid foundation for growth. Sustainable Energy is currently focused on expanding to new markets, and developing additional products to satisfy the needs of a broader customer base.

The Company is headquartered in Calgary, Canada, and was founded in 1999 to develop power conversion products for Fuel Cell applications. The company has since adapted its universal technology platform to higher growth markets, and is committed to bringing efficient, reliable renewable energy to customers around the world.

Sustainable Energy is a publicly traded company with common shares listed on the TSX Venture exchange under the symbol “STG”.



SUNERGY 5 Inverters

For long term reliability, SUNERGYTM inverters use a unique approach to power conversion enabling much simpler power electronics circuits that are inherently more robust. The superior thermal properties of the SUNERGY 5 design also protect the electronics from excessive heat.



No Thermal Rollback
The SUNERGY 5 Inverter sets a new benchmark for reliability and productivity in solar energy systems

The patented approach to power conversion enables the SUNERGY 5 inverter to operate with low voltage inputs which is ideal for parallel solar string layouts.



Current inverter designs demand that identical modules be arranged in long series to match the high voltage requirements of the inverters. These inverters are based on pulse width modulation technology (PWM), which cannot be designed for low voltage inputs without a substantial loss of efficiency.

Sustainable Energy Technologies patented pulse step technology is a breakthrough in the development of low voltage systems

The SUNERGY 5 inverter reduces the operating voltage range for solar arrays from industrial levels to well below utility norms for residential and commercial sites, significantly improving safety


Inverters are available for packaging with most small wind turbines. OEM applications include 1 to 10 kW turbines with the following base configurations:

  • 24 Volt, 1.8 kW inverter
  • 48 Volt, 3.6 kW inverter
  • 10 kW dual inverter package

The fast control response of Sustainable Energy’s inverters is ideal for capturing full power from every gust of wind

For small wind systems, a high percentage of energy must be collected during a low percentage of the time.


  • Every unit increase in wind speed results in an exponential increase in power, making responsive systems critical for optimal power output (P~V3).
  • Sustainable’s wind inverters have been designed to respond rapidly to gusts to provide the highest possible efficiencies.

Sustainable Energy’s inverters can be used for hybrid systems incorporating solar panels, wind turbines, and even battery backup systems

Aerotecture International seeks to radically transform the dominant paradigm of energy production and consumption around the globe. Blending the concepts of aerodynamics and architecture, Aeroturbines are wind electric turbines designed to be attached to buildings or integrated into the very form of buildings. With Aeroturbines, buildings and other structures will not only consume electricity, but produce it on-site.


Aeroturbines are wind turbines designed for urban settings.  Invented by University of Illinois industrial design professor, Bil Becker, Aeroturbines are a new development in wind turbine technology.  Aeroturbines can be installed on existing rooftops or built into the architecture of new buildings to provide clean renewable electricity at its site of consumption.  Aeroturbines are uniquely suited to urban environments because they are:

  • Noise and vibration-free
  • Safe for birds
  • Able to utilize multi-directional and gusting winds
  • Self-regulating (no overspeed protection required)
  • Low maintenance
  • Made from low-cost and readily available materials

The structural features of the Aeroturbine allow for its easy integration into new or existing buildings: the modular/stackable cages are additive and can be mounted in a vertical, horizontal, or diagonal orientation.

There are currently two models of Aeroturbines available, the 510V and the 520H.  Both models of the Aeroturbine may be easily integrated with solar photovoltaic systems.

In order to operate efficiently, Aeroturbines must be installed 40 ft. above the ground, above or away from surrounding trees and other obstruction, and in an area with average wind speeds of at least 10 mph.

Aerotecture is currently developing and testing their final prototype of the Aeroturbine.  Once perfected, which may be as soon as mid 2007, Aeroturbines will be available for limited multifamily residential buildings, institutional buildings and commercial buildings.

They currently do not have an extensive dealer network in place. You would need a dealer in your area to take delivery of the Aeroturbine, install it and possibly maintain it properly. We currently have dealers located in Chicago, Illinois; upstate New York; Paterson, New Jersey; and San Francisco, California. Only projects 100 miles of these dealerships will be considered at this time.

Peak oil. Inflation. Global warming. Conflict. Today’s headlines make it clear: we need a sustainable, affordable source of energy that protects the environment and meets the needs of nearly 7 billion – and growing – aspiring, remarkable humans.

EdeniQ’s scientists are pursuing solutions that cost-effectively convert abundant, non-food biomass into fuels. Making fuels from agricultural waste such as corn stover, sugarcane bagasse, rice straw and woodchips takes the controversy out of biofuels and puts the green – and the humanity – in.

Their name says a great deal about their mission. EdeniQ is an intentional misspelling of Edenic an adjective meaning “of or pertaining to the Garden of Eden.” The “IQ” ending of EdeniQ connotes intelligence. Together Eden IQ expresses our profound desire to engage in the wise use of all that nature provides.

Most of the energy plants store is not in their seeds, fruits or tubers. Most of the energy they store is in their actual structure, the so-called lignocellulosic parts of the plant. But these stiffer, woodier parts of plants, though rich in complex sugars, are not easily broken down into useable energy. Yet, we all know that given enough time, even the mightiest trees decay. There are animals, plants, bacteria and fungi that make their livings off of plant structure. In nature, nothing is wasted.

Harnessing natural processes that breakdown complex lignocellulosic materials into simpler sugars that can be fermented or otherwise crafted into fuels is just one area where EdeniQ’s team has made significant breakthroughs.

With natural processes as their guide, they give consideration to every aspect of turning biomass into useable energy. This means thinking not only about how to breakdown complex lignocellulosic polymers, but also about the use of water, the generation of waste, and the input of energy. Unlike other cellulosic ethanol processes EdeniQ’s process does not use harsh acids or rely on expensive metal catalysts. And, the heat and electricity needed for production are derived by burning residual lignin (the toughest of all plant matter). The end result is carbon-neutral energy that does not add incremental CO2 to our atmosphere.

By emulating nature, EdeniQ knows that remarkable things happen: processes become cyclical, adaptable and efficient. Costs actually decrease. To thrive in the 21st century it is clear that nations, companies, investors, shareholders and citizens alike must embrace the awesome, ancient lessons of our living world. EdeniQ does exactly that.


EdeniQ’s technologies help new and existing biofuels producers derive clean, affordable energy from a wide variety of biomass.

Their patented processes can be implemented for a fraction of the $6 to $12 per gallon capital cost it takes to build a cellulosic plant employing today’s acid hydrolosis or syngas technologies. And, by eliminating expensive catalysts and additives, EdeniQ’s solution is not only capital efficient, but also costs far less to operate.

EdeniQ knows that cellulosic ethanol will only enter the mainstream when the following key conditions are met:

  • The processes for breaking down complex lignocelluosic materials must be fast and affordable;
  • These processes must not produce wastestreams that are expensive to handle and deleterious to the environment;
  • The refining processes must not use fossil fuels to generate the required inputs of heat and electricity;
  • The plants employing these processes should not be tied to the use of any one type of feedstock, but rather be free to work with a wide variety of feedstocks;
  • The processes should cost-effectively yield sugars that can be fermented or otherwise processed into a range of fuels (not just ethanol);
  • The processes should be water efficient (meaning that a significant portion of the water required is reused);
  • When measured end-to-end, the fuel produced by these processes should be carbon-neutral (i.e., not introduce incremental CO2 into the atmosphere);
  • The processes should take advantage of valuable co-products;
  • The processes should be able to work with many elements of today’s existing biofuels infrastructure and not require a complete overhaul of the industry;
  • Plants should be able to add the processes in an incremental fashion by deploying profitable modules that help manage precious capital;
  • The all-in cost of a gallon of fuel produced by these processes must be under $1.50 per gallon;
  • The processes need to be available today, not 2-5 years from now.

PrimeStar Solar has an experienced and dedicated team with core competencies in thin film photovoltaics (PV) and thin film deposition equipment. The company’s proprietary semiconductor technology and equipment have been optimized for automated continuous manufacturing for high throughput and yield that will result in low cost PV modules. The thin film technology requires far less semiconductor material and far less energy to manufacture PV modules than conventional crystalline silicon PV. PrimeStar Solar’s product is designed to enable economically competitive large scale solar PV power plants that will help offset the negative environmental impacts of fossil fuel electricity generation.

PrimeStar Solar is scaling up the world record efficiency thin film cadmium telluride PV technology that was developed at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). NREL is the primary national laboratory in the United States for renewable energy and energy efficiency research and development. It is recognized as the world’s leading thin film PV research institution. PrimeStar is uniquely positioned for ongoing collaboration with NREL by virtue of its corporate development center being located within a 10 minute drive of the lab. To further enhance this interaction, in February 2007, PrimeStar Solar signed a cooperative research and development agreement with NREL.

In June, 2007, PrimeStar Solar was awarded a $3M U.S. Department of Energy Solar America Initiative contract for commercial scale up of the world record cadmium telluride PV technology. The Solar American Initiative is a national program started in 2006 to ensure that solar energy technologies will play a growing role in U.S. energy supplies and the U.S. economy by making the technology cost-competitive in the near future. PrimeStar Solar was chosen as one of ten awardees. The contract is milestone based with stage gate reviews and off ramps for non-performing awardees. PrimeStar Solar is pleased to have successfully met all milestones and passed through all stage gate reviews to date.

PrimeStar Solar is a private company with strategic investment partners. Initial financing of $6.2M was secured in the fall of 2006. In September 2007, GE Energy, one of the world’s leading suppliers of power generation and energy delivery technologies, took a minority equity position in PrimeStar Solar. In June 2008, GE Energy increased its equity share in PrimeStar Solar becoming a majority shareholder. This solid financial backing is allowing PrimeStar Solar to proceed with confidence in its commercialization effort.

You have to wash plastic to recycle it, but traditional recycling technology uses billions of gallons of water each year in the process. A decade ago, industry veteran, Gary De Laurentiis, set out to change that. He discovered a process developed by Honeywell and the Department of Energy for recycling used HDPE oil bottles. This would be the inspiration for the process Eco2 plastics utilize today.


Following years of research and development in conjunction with researchers from Honeywell, he expanded the process to clean PET beverage containers by combining a biodegradable solvent and liquid carbon dioxide to replace traditional water-based methods. With this newly patented technique, he gave the world a completely closed-loop plastic recycling system — one that uses no water and continually reuses the cleaning agents.

The company built around that idea is now known as ECO2 Plastics. They’ve assembled the finest, most experienced minds in the plastics and recycling industries to revolutionize the business. Recognizing the benefits of their process, the State of California supported the company with a loan in 2005. Private investors have invested over $20 million. They are now in full-scale production in California, and have plans for 10 plants in the U.S. within five years.

But the idea doesn’t stop there. They now see additional applications for this unique process and they are hard at work on next generation technology, such as work currently underway with USCAR.

They’re making plastic recycling more ecological, more economical, and quite simply more logical. A process they call eco.logical.recycling.



PET plastic flakes are a commodity product, processed and delivered to industry for use in hundreds of applications. Our product is virtually identical to traditionally recycled plastic, but produced in a more efficient and earth-friendly way.

Quality Assurance.

Their recycled plastic is of the highest quality. It is odor-free and contaminant-free to 100 parts per million. Every 1,000 pounds is tested for intrinsic viscosity, melt flow, density, moisture content and PVC content. You’re guaranteed a perfect product.

GreenVolts, Inc., based in San Francisco, was founded in 2005 to deliver solar power at fossil fuel costs. The company’s breakthrough high concentration photovoltaic (HCPV) technology efficiently integrates tracking and optics into a system that dramatically lowers energy cost. Through low cost and high efficiency, GreenVolts can access large markets previously inaccessible to solar power. GreenVolts changes the economics of solar energy.

In September 2006, GreenVolts won the California Clean Tech Open business plan competition and a grant from the California Energy Commission. The company recently signed a power purchase agreement with Pacific Gas & Electric Company for a two megawatt HCPV power plant that, when completed, will be the largest in the world. GreenVolts has also executed a contract for field-testing with Avista Corp, a $1.5B public utility based in Spokane, Washington.


GreenVolts’ patent pending CarouSol™ system is a two-axis sun-tracking platform onto which an array of power units is placed. These power units use mirrors to concentrate 625 suns of energy onto high efficiency photovoltaic cells. The CarouSol is built close to the ground to ensure low installation and maintenance costs and reduce wind loading.

GreenVolts Key Advantages

The CarouSol system’s optical and tracking devices were designed together in order to provide a great increase in performance over other CPV systems. GreenVolts’ patent pending optical design allows for tighter packing, generating more energy from a given land area than any other solar technology.

GreenVolts’ patent pending high concentration photovoltaic system produces energy at less than half the cost of traditional solar panels.

GreenVolts’ system can be installed nearer to the load than other technologies, eliminating the wait for new transmission lines or turbines to be delivered. The CarouSol system is designed for simple, high-volume manufacture and snap together assembly. The CarouSol system is modular and easy to access for low cost maintenance. Installation requires no heavy equipment to speed project approval, permitting, construction, and completion. Precision sheet metal manufacturing allows for rapid scale-up of manufacturing of the CarouSol with plant capital costs that are an order of magnitude lower than thin film plants. CarouSol systems are lightweight and can be placed on the ground or on a roof without piercing the roof surface. The low profile CarouSol reduces wind loads by a factor of 10 over other designs, lowering costs and increasing performance. The patent pending off-axis design on a rotating platform reduces shading and increases performance. The CarouSol system’s wide base also increases tracking control accuracy, which allows for increased energy output.

Wakonda Technologies

Wakonda Technologies





Wakonda Technologies is developing proprietary solar electric technology that is more efficient than crystalline silicon and lower in cost than thin film alternatives.

Wakonda combines the world’s most efficient photovoltaic materials with a flexible substrate that enables high volume manufacturing using commercial processes. The result:

•Costs competitive with conventional electricity
•Elimination of rare and toxic raw materials
•Wide variety of product forms

Their technology will dramatically improve the availability of solar energy for both critical military and broad commercial applications, making it possible for everyone to harness The Power That Resides in Nature™.

Solar electricity can significantly reduce greenhouse gas emissions. Solar energy is most effective when electricity is needed most – during the heat of the day. Solar enabled peak load reduction will improve the reliability of the grid and reduce the need for additional centralized power generation. Solar power is generated at the point of use, eliminating transmission and distribution losses.


Industry Status

Wakonda Technologies is actively working to reduce the average cost of solar systems to make solar energy competitive with conventional electric power. Solar cells and modules account for 40-50% of the cost of today’s solar systems.  Solar electricity averages 3-5 times the cost of centrally generated electricity, independent of the technology used in manufacturing of the cells.

Crystalline silicon, the same material used in the mass production of computer chips, accounts for over 90% of the commercial solar cell market.  Silicon cells are typically 11-16% efficient.  They are also rigid and relatively fragile.

Lower cost thin film solar cells based on amorphous silicon, copper-indium-gallium-diselenide, or cadmium-telluride make up the rest of today’s commercial market.  These materials absorb light better than crystalline silicon, so they can be deposited in layers less than 1 micron thick on flexible substrates such as stainless steel foil.  This flexibility allows high volume roll-to-roll production using processes similar to photographic film manufacturing.  Despite laboratory efficiencies over 15% and over 20 years of development, commercial thin film cells are only 5-8% efficient and their performance degrades over time.  In addition, indium and tellurium are rare and expensive raw materials.

The highest efficiency solar cells in production today are based on III-V semiconductor materials such as gallium-arsenide.  These cells were developed for specialty applications such as satellites and are over 30% efficient.  III-V cells trade efficiency for cost – the single crystal germanium substrates used in their production cost over $10,000 per square meter, well above costs acceptable for commercial applications.

Wakonda’s Advantage

Evolutionary developers are seeking ways to reduce the inherent high material cost  of crystalline silicon or to increase the inherent low efficiency of existing thin film materials,  Wakonda is developing a revolutionary method to significantly reduce raw materials cost – the primary cost driver in production of inherently high efficiency III-V cells.

Our virtual single crystal uses a proprietary surface treatment that allows a low cost, commercial metal foil to simulate an expensive single crystal wafer.  The result is a new paradigm in solar cell manufacturing, combining:

  • High efficiency III-V cell technology, and
  • Proven, low cost manufacturing processes.
