The bumper to bumper measures 4.6 m (15.18 ft) weighs 815 kg (1793 lb) that includes 1200 lb (550 kg) of plastics has a gas/electric hybrid power system, air bags, neon tube tail-lamps, etc. and gets 132 km (60 miles) per gallon of fuel. Huatong and the Chinese government have funded 100 million in this global project. 

Other possible applications of smart elastomers are in the area of polymer engine which can produce maximum power density (4 W/g) and output both in terms of electrical and mechanical power without any noise. These features are superior compared to conventional electrical generator, fuel cell, and conventional IC engine. Many DoD applications (e.g., robotics, MAV) require both mechanical and electrical (hybrid) power, and polymer engine can eliminate entire transducer steps and can also save engine parts, weight, and is more efficient. 

There is a major potential for energy conservation in transportation, by increasing the energy efficiency of automobiles. The recent commercialization of hybrid vehicles, which combine electric and gasoline motors, demonstrates how much more efficient automobile transport can be. Hybrid power systems deliver double the fuel efficiency of conventional engines. Moreover, as fuel cells are perfected, even greater energy efficiencies may be achieved.

Advanced power generation cycles that combine high-temper-ature fuel cells and gas turbines, reciprocating engines, or another fuel cell are the hybrid power plants of the future. As noted, these conceptual systems have the potential to achieve efficiencies greater than 70% and projected to be commercially ready by the year 2010 or sooner. The hybrid fuel cell/turbine (FC/T) power plant will combine a high-temperature, conventional molten carbonate fuel cell or a solid oxide...

The most recent system is a 220 kilowatt fuel cell/gas turbine power plant operating at the University of California s National Fuel Cell Research Center located in Irvine, California. The first-of-a-kind hybrid power plant consists of a 200 kilowatt fuel cell generator pressurized at about 3.5 atmospheres in combination with a 20 kilowatt two-shaft gas turbine. The system was first run at the Pittsburgh facility and started operating at Irvine in June, 2000. Total run time until July, 2000 was 264 hours. Electric energy delivered was 42 megawatt-hours. Electric efficiency was 51% (LHV). An electric power feed-through mounted on the pressure vessel devel-... 

Recently a new hybrid power source has been reported that couples oxidation at a dye-photosensitized nanocrystalline semiconducting SnOz photoanode with the enzyme-catalyzed reduction of O2. Although miniaturization has not yet been reported for this new hybrid, the developments already achieved to miniaturize biofuel cells coupled to those being developed for charge-insertion oxides should be technically transferable to this system. 

A more recent paper considered the use of a hybrid power supply for powering autonomous microsen-sors. ° Such devices are similar to the dust mote pictured in Figure 1 and described in the Introduction. This hybrid power supply combined a solar cell to meet standby requirements and to charge the battery, which was the microfabricated Ni—Zn battery described in section 3.2. The authors also showed that if the battery alone was to serve as the power source, the footprint would be substantially larger, over 12 cm . The hybrid device was constructed and some feasibility experiments were carried out, but no actual devices were powered.

In conclusion, supercapacitors are robust devices better capable of energy storage in electrical vehicle applications, backups, and highly reversible power sources for computer storage, than conventional capacitors. For the former application, supercapacitors can be a part of hybrid power sources, which also include high-energy-density batteries in which the supercapacitors provide the high power required.
