In the past,the DOE,SBA,and DARPA had grants to small businesses for fuel economy R&D with an aim on commercialization.
Companies which qualified,like Continuum Dynamics,were allowed full-scale testing there at Palo Alto.
An initial $50,000 would provide for proof of concept,then when efficacy was demonstrated,another $350,000 would be provided towards getting it into production.
Today's 'box-cavity' is a lineal descendant of Continuum's research.
