For example, although cellulose fuel sources, such as grasses, could be important for future production of ethanol, the high cost of processing is a barrier. Make fuels and vehicle technologies more compatible. For all new engine technologies, changes in fuel will be key to achieving low emissions, high efficiency and acceptable cost and performance. Cost comparisons should encompass both the vehicle and the fuel and should be based on similar levels of technological maturity. Support critical research.
Nanotechnology promises to be revolutionary, but it is still at the level of basic research.
More long-term work is needed. Build a national network. A network of centers of excellence at top universities would form strong and enduring partnerships with all sectors. Partner, partner, partner. Multidisciplinary partnerships will be essential if we are to exploit nanotechnology discoveries effectively.
