247Solar Inc., a spinoff of MIT, along with microturbine supplier Capstone Turbine Corporation, today announced the successful test of a revolutionary commercial turbine that can generate electricity using hot air at atmospheric pressure, without combustion. This breakthrough is made possible by an ultra-high temperature heat exchanger with technology that has its origins at the Massachusetts Institute of Technology (MIT). The 247Solar Heat Exchanger uses a proprietary nickel-chromium-aluminum-iron alloy engineered for sustained operation at very high temperatures. For its size, the heat exchanger is the most compact and materials-efficient in …
