U.S. DOTs Zero Emissions Transportation Initiative is looking to push the transportation sector greenhouse gas production to zero by 2050. This solicitation/topic addresses alternative energy sources for the light vehicle, motorcycle, and bicycle sector. With the continuing significant development in commercialization and availability of biofuels, the possibility exists to meet this goal, with an achievable near term 95 to 97.5% efficiency using an internal combustion engine. A scalable high power, very fuel efficient, Super Ultra-low Emission biodiesel-electric hybrid propulsion system is AEDs alternative energy source selection. The Phase I activities will research, analyze, evaluate, and select the technologies and components necessary to best reduce CO2 emissions and support the concept design of a 250-350cc biodiesel-electric hybrid transportation/sport motorcycle. This motorcycle will have the potential of 200+ mpg highway and 350 mpg city. Phase I activities will conclude with the selected design/configuration of the concept demonstrator motorcycle to be built, tested and developed during Phase II. AED is a 31 year, veteran owned, internal combustion engine R & D Corporation. AED will combine its vast advanced diesel engine and motorcycle technology experience with state-of-the-art production diesel and electric hybrid components to meet the objective of this solicitation.
