Fuel cell powered electric cars using on-board methanol or hydrocarbon reforming to produce a hydrogenrich gas represent a low-emissions alternative to gasoline internal combustion engines (ICE) with well-towheel efficiencies of 17 %. For the overall methanol process, a simplified model of the reaction network consisting of the total oxidation of methanol, the reverse water-gas shift reaction, ...

Recent progress on fast ignition (FI) enables us to design an IFE power plant with a 1MJ-class, compact laser whose output energy is 1/4 of previous central ignition scheme. Basing on the FI scheme, we conceptually designed a laser fusion power plant driven with cooled-Yb:YAG, ceramic lasers. In this design activity, we newly evaluated the gain curve for FI basing on latest simulation code. Coo...

The development strategy of nuclear fusion energy in the Korea National Basic Plan for the Development of Fusion Energy consists of several major programs. These are shown in Fig. 1, and include KSTAR for the study of a long-pulse, advanced tokamak operation, ITER for a burning plasma experiment, the DEMO reactor for the demonstration of producing net electricity from a fusion reactor, and a co...

MIT has been developing a conceptual design for pebble bed reactors since approximately 1998, when a student design project concluded that in order to resurrect the nuclear power industry a new, innovative approach was needed, not only in reactor design but also in construction and operation. In their quest to identify the appropriate technology several key conclusions were reached. First was t...

Until recently traditional heating in organic chemistry has been done with oil heating baths or using electric heat exchangers. With the advent of microwave equipment, heating by microwaves was rapidly introduced as standard method in organic chemistry laboratories, mainly because of the convenient possibility to operate at high temperature accompanied by accelerated reaction rates. In the pres...

Based on a comparative analysis of the advantages and disadvantages radioisotope nuclear reactor power generators in space applications, this paper determines that generator is energy scheme Neptune exploration mission, proposes four kinds major scientific problems involved exploration, introduces preliminary ideas, such as function module, fight orbit, design constraints mission....

Different microbial electrochemical technologies are being developed for many diverse applications, including wastewater treatment, biofuel production, water desalination, remote power sources, and biosensors. Current and energy densities will always be limited relative to batteries and chemical fuel cells, but these technologies have other advantages based on the self-sustaining nature of the ...

Executive Summary Princeton Satellite Systems and the Princeton Plasma Physics Laboratory (a Federally-Funded Research and Development Center) are collaborating on a breakthrough concept, the Direct Fusion Drive (DFD), a D – 3 He fueled fusion-powered rocket engine. The design is based on the Princeton Field-Reversed Configuration Reactor (PFRC) concept for a compact, clean, steady-state fusion...

In this study, a twin-chamber upflow bio-electrochemical reactor packed with palm shell granular activated carbon as biocarrier and third electrode was used for sequential nitrification and denitrification of nitrogen-rich wastewater under different operating conditions. The experiments were performed at a constant pH value for the denitrification compartment. The effect of variables, namely, e...
