Success Stories

  1. SBIR-STTR-Success: Mainstream Engineering Corp.

    Stationing hungry soldiers in an Iraqi desert where temperatures can exceed 130 degrees Fahrenheit presents obvious logistical challenges. Refrigerating food is necessary but difficult, especially in remote locations. It’s also expensive and potentially dangerous to transport fuel to power the...
  2. SBIR-STTR Success: Mainstream Engineering

    Nearly thirty years ago, brand new Florida-based Mainstream Engineering received two small SBIR awards from the U.S. Air Force for the development of spacecraft heat rejection systems. But Dr. Robert P. Scaringe, President and Founder, already had transition on his mind long before that.“Taking a...

Award Listing

  1. High-Selectivity, High-Flux Gel-Based Membrane for the Separation of Carbon Dioxide

    Amount: $199,724.00

    Much of the U.S. energy comes from fixed, large-scale fossil fuel power plants, which will remain the case for the foreseeable future. Therefore, in a carbon-constrained environment targeted at preven ...
