Utilization of wasted heat instead of fuel combustion is effective to reduce primary energy consumption for mitigating global warming problem. Because wasted heat sources are not necessarily located close to areas of heat demand, one of the difficulties is that wasted heat has to be transferred from heat source side to heat demand side, which may require heat transportation over long distance. ...

Self-cooled liquid metal breeder blankets have a high potential to meet the overall goal of fusion research to develop an economically and environmentally attractive energy source. They offer the possibility to design mechanically simple blanket segments, employ a high-temperature, low-pressure coolant, allow for a high power density, and as consequences of these, achieve high efficiency and av...

Ice-slurry is an ideal form of ice product for ice-storage, which is an effective measure to save energy. The conventional producing method using super-cooled water suffers the troubles of instability and heavy dependence on electronic power. We propose a novel method to improve that: spraying water is super-cooled by evaporating in a chamber where the air is of low humidity and low wet bulb te...
