Transaera is developing a new class of affordable, energy-efficient,environmentally friendly cooling systems.

Takachar creates a network of waste management enterprises in Kenya that turn unmanaged agricultural residues into charcoal, a low-cost, non-toxic, and eco-friendly cooking fuel for low-income households. They have developed a series of low-cost (US$20), locally manufacturable technologies to enable waste-to-char conversion, which has been tested and refined in Kenya for the past 3 years. Since 2011, They have set up or directly helped 7 nascent and locally run waste-to-charcoal enterprises in Kenya, some of which have since even demonstrated operational profitability and paying customers. So far they have created about 100 jobs and sold 50 tons of eco-char. Moving forward, they are trying to prove the long-term financial viability of these enterprises, which, if successful, will be the basis of a franchise network.

DropWise Technologies specializes in advanced coating solutions designed to enhance efficiency in heat exchange systems, particularly for power plants. Founded in 2014 and based in Cambridge, Massachusetts, the company utilizes a unique vapor-based deposition process developed in collaboration with leading MIT labs. This innovative technology produces ultra-thin, durable coatings that significantly reduce fouling and corrosion, enabling power plants to generate electricity using less coolant water. The coatings are versatile, applicable in various sectors including power generation, desalination, HVAC/R, and chemical refining. By chemically grafting coatings to surfaces with nanometer precision, DropWise addresses the limitations of conventional liquid coatings, which are often too thick and ineffective. Their products not only improve heat transfer rates—up to seven times greater—but also provide protection against harsh environments, making them suitable for a wide range of industrial applications.

7AC Technologies Inc., based in Beverly, Massachusetts, specializes in innovative HVAC solutions using its advanced membrane-isolated plastic plate technology. This technology supports the development of ultra-efficient liquid desiccant systems designed for commercial and industrial buildings. By utilizing this approach, 7AC Technologies aims to significantly reduce energy costs, achieving a reduction of over 50% compared to traditional HVAC systems. Originally founded as 7Solar Technologies, Inc. in 2009, the company rebranded in 2011 and is currently a subsidiary of Emerson Electric Co.
