GreatPoint Energy is a technology-driven natural resources company commercializing catalytic gasification to convert abundant coal, petroleum coke and biomass into low-cost natural gas (methane) while capturing and sequestering CO2.

Utilizing its proprietary conversion and carbon capture technology, GreatPoint Energy develops bluegas™, coal-derived natural gas. bluegas™ is 99.5 percent pure methane and can be transported throughout North America utilizing existing natural gas pipeline infrastructure, providing an attractive, cost-effective alternative to drilled and imported natural gas. Its environmental profile is as clean as natural gas; it consists mostly of hydrogen and therefore, has very low carbon emissions. Moreover, bluegas™ can be used in every application that natural gas is currently being used (i.e., power generation, residential and commercial heating, and production of chemicals).


GreatPoint Energy is following in the footsteps of the petroleum refining industry by implementing a more advanced and lower cost process for refining carbon-based feedstocks. In the early days of petroleum production, oil refineries – like today’s coal gasifiers – relied on intense heat (called thermal cracking) to break down heavy crude oil into light useable petroleum products. In the 1940’s however, scientists discovered that a catalyst could be used to minimize the amount of heat required. This lower cost and higher efficiency approach quickly replaced thermal cracking in oil refineries around the world.

GreatPoint Energy’s technology uses the same basic technique to “refine” coal by employing a novel catalyst to “crack” the carbon bonds and transform the coal into clean burning methane (natural gas). This single stage process is called catalytic coal methanation and forms the basis of the GreatPoint Energy bluegas™ process.

By adding a catalyst to the coal gasification system, GreatPoint Energy is able to reduce the operating temperature in the gasifier, while directly promoting the reactions that yield methane, CH4. Under these mild “catalytic” conditions, less expensive reactor components are required, pipeline grade methane is produced, and very low cost carbon sources (such as lignites, sub-bituminous coals, tar sands, petroleum coke and petroleum resid) can be used as feedstocks.

In addition, GreatPoint Energy’s catalytic coal methanation process eliminates troublesome ash removal and slagging problems; reduces maintenance requirements; increases thermal efficiency; and eliminates the air separation plant (a system which alone accounts for 20 percent of the capital cost of most gasification 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.

Coskata, Inc. is a biology-based renewable energy company, with technology for the production of liquid fuels. Using proprietary microorganisms and transformative bioreactor designs, the company will produce ethanol for under US$1.00 per gallon anywhere in the world, from almost any input material (feedstock).

Coskata is commercializing a proprietary process and related technologies for the conversion of a wide variety of input materials into ethanol. Coskata has an efficient, affordable, and flexible three-step conversion process:

1. Incoming material converted into synthesis gas (gasification)
2. Fermentation of the synthesis gas to ethanol (biofermentation)
3. Separation and recovery of ethanol (separations)

During gasification, carbon-based input materials are converted into syngas using well-established gasification technologies. After the chemical bonds are broken using gasification, Coskata’s proprietary microorganisms convert the resulting syngas into ethanol by consuming the carbon monoxide (CO) and hydrogen (H2) in the gas stream. Once the gas-to-liquid conversion process has occurred, the resulting ethanol is recovered from the solution using “pervaporation technology.”

Coskata’s proprietary microorganisms eliminate the need for costly enzymatic pretreatments, and the bio-fermentation occurs at low pressures and temperatures, reducing operational costs. In addition, the Coskata process has the potential to yield over 100 gallons of ethanol per ton of dry carbonaceous input material, reducing both operational and capital costs. Coskata’s exclusively licensed separation technology dramatically improves the separations and recovery component of ethanol production, reducing the required energy by as much as 50%.

Coskata Ethanol


Ethanol is a clean burning fuel, with the ability to be completely renewable and transform the global fuel market with its many positive attributes:


  • Ethanol from renewable sources is environmentally friendly, reducing greenhouse gas emission levels substantially
  • Ethanol is great for the U.S. at large, helping to alleviate dependence on foreign sources of oil and allowing for domestic fuel production
  • Stimulates the economy and increases the value of domestic resources while creating jobs
  • Ethanol is great for the consumer because it can reduce fuel costs

However, not all biofuels are created equal. Coskata does NOT make ethanol from food products; it makes the fuel from sources like municipal solid waste (trash), agricultural and forest residuals, bagasse and many other carbon containing input materials. Coskata’s process technology converts what has frequently reached the end of its useful lifecycle into renewable energy, while being energy positive.
