Romny Scientific offers both the materials and module technology to produce useful electrical power from wasted heat. In the academic world, thermoelectric materials are most commonly judged by zT, the thermoelectric figure of merit. zT can be used to estimate the maximum performance of a thermoelectric generator, operating under ideal conditions.

Creating a high performance product to delivery useful power in the real world is more complicated. A material must have a high zT, be formed at low cost using low cost raw materials. A real world material must be reliable and robust, having the mechanical properties to delivery electrical power for decades in extreme operating conditions. Increasingly major markets demand materials that do not contain lead or other toxic elements. Romny delivers materials for real world scalability.

One key metric that drives Romny's work industrializing thermoelectric technology is a material's performance per $. Romny delivers materials that are lead free, with unparalleled performance per $. The plot below illustrates the performance per production cost of two of Romny's lead free materials compared to a traditional lead telluride material. These materials offer similar power generation efficiency as the traditional lead telluride, but are manufactured using low cost production methods and low cost raw materials. As a result, Romny's materials offer a greater than 20X advantage.

Romny integrates its high perforance materials into thermoelectric modules that together delivery long term reliability. For information on how Romny's lead free thermoelectric materials and modules can impact the efficiency of your project, click contact above.
