Today’s hybrid and plug-in electric automobiles are able to recover some of the energy normally lost to friction during braking. Even in today’s cutting-edge vehicles, however, a large amount of kinetic energy is still lost to braking during the typical stop-and-go urban commute. INSTAR is a system designed to greatly improve on existing technologies in order to recover the maximum amount of kinetic energy normally lost during braking. The energy recovered will be converted into usable electric energy. This recovered energy can then be used to power the vehicle, thereby increasing the travel-range and battery life of plug-in and hybrid vehicles. By increasing the efficiency and functionality of hybrid and electric vehicles in this way, the INSTAR system could make these vehicles significantly more attractive to consumers and increase adoption rates.
Using Demand Management to Address the Problem of Intermittent Water Supply: The Capellanía Water System in Panama (UC Berkeley)
Many piped potable water systems in developing countries do not provide continuous service. Intermittent supply is a nuisance to users and can degrade water quality.
