Core4 Systems is developing a system to more efficiently cool data centers. Core4's promised energy savings comes from reduced compression, achieved in a number of ways. Instead of filtering external air, Core4 claims to use only internal air ¢‚¬" in a method called refrigerant-side economizing ¢‚¬" which attempts to mitigate the filtering costs while cutting compressor energy consumption.Per the company, Core4 also uses outside wet-bulb temperatures ¢‚¬" the temperature at which water begins to evaporate outside ¢‚¬" rather than the higher dry bulb temperature, which aims to allow its gear to continue economizing even on extremely hot, humid days when airside systems can't. Refrigerant-side economizing also cuts down on server and hard drive failures, which contribute to the volume of e-waste shipped to overseas landfills.

Indie Energy geothermal-based clean energy building systems deliver dramatic energy savings, reduced carbon emissions, and healthier indoor air using the natural energy right below the company's feet. Indie Energy geothermal building systems save between 50% and 80% on annual heating, cooling, ventilation, and hot water costs in commercial, residential, and public buildings. n

Visible Energy aims to provide customer-friendly monitoring services that reduce energy usage and costs. This information aims to enable customers to connect via an Internet community to compare personal energy use across the entire electrical grid. Incorporated in July 2007, Visible Energy is aims to empower homeowners, schools, and businesses to change their habits and to save money, reduce their carbon footprint, and increase energy security. VE was founded by a group of scientists and engineers from Northern Arizona University.

Hexaformer's technology aims to make it possible to manufacture closed symmetrical delta shaped transformer cores. Per the company, it does this by winding the transformer core instead of stacking sheets of metal. The benefits according to the company of this design to transformers include: a lower load loss, lighter, smaller volume, less vibrations, less noise, smaller electromagnetic stray fields, lower inrush current, and no third harmonic. The same type of technology is also used in the Hexaformer reactors for phase compensation. These cores are also wound to a triangular shape on which three coils are mounted to make the solutions small, yet efficient. The benefits per Hexaformer of this transformer technology include reducing the losses in the electricity grid as well as lowering the cost of operation and maintenance by 5% to 15% compared to traditional transformers.
