Pyro-E's energy conversion device provides a unique solution to boost the efficiency of small, distributed energy systems. Recently, advances in photovoltaics have led a paradigm shift towards direct energy conversion. This shift also points to the need for effective heat to electricity conversion where no solution currently exists for one of the largest and most accessible energy source in the country. That is, the US in 2010 released 56 percent of the total energy produced into the atmosphere in the form of waste heat and pollution. Yet, no viable solution exists given the engineering challenges in manufacturability and cost. By overcoming the above, the proposed technology will address the critical need for increasing the energy-use efficiency of 1) fuel cell and diesel generators; 2) gasoline automobile and hybrids; and 3) industrial furnaces and gas pipelines. The broad, long-term objective is to achieve cost-parity with turbines for power generation, 4-times longer life, and the equivalent savings on maintenance. This provides benefit to society in the form of cheaper energy, less reliance on fossil fuel, and improved environmental quality.
