Small Business Administration looking for tech innovators to provide a "non-electric heating solution" in the wake of Hurricane Sandy. The SBA has an urgent call for innovation. According to an email notice sent by the SBA on Tuesday, the agency has asked Defense Alliance, a company that has been awarded an SBA grant, to help small businesses get government contracting jobs through the Department of Defense, Department of Energy and others "to put out a call to our membership for an urgent technology need in the wake of Hurricane Sandy."
