This study has investigated the feasibility of three different solar-assisted air conditioning systems for typical medium-sized office buildings in all eight Australian capital cities using the whole building energy simulation software EnergyPlus. The studied solar cooling systems include: solar desiccant-evaporative cooling (SDEC) system, hybrid solar desiccant-compression cooling (SDCC) syste...

Solar water heaters are good tools for saving fuel. The main component of these water heaters is collectors, which are responsible for absorbing solar energy and transferring it to the working fluid with the least heat dissipation. The present study is an experimental study of the performance of the solar semispherical collector with 1 m2 of absorber area at different volumetric flow...

Solar sailing is a proposed means of space propulsion in which a reflective surface collects momentum from solar photons to accelerate a vehicle. The current trend within the solar sailing community is to increase sail size as solar sailing technologies advance, allowing for larger payloads and higher accelerations. However, with the miniaturization of modern payloads, sail sizes can be dramati...

We developed an appropriate Absorption chiller to "Solar cooling system" in 2010. In addition, we added the improvement to the machine. "Solar cooling system" can be easily constructed with the machine. and, we constructed the demonstration plant, and verified the utility

Life, defined as a chemical system capable of transferring its molecular information via self-replication and also capable of evolving, must develop within a liquid to take advantage of the diffusion of complex molecules. On Earth, life probably originated from the evolution of reduced organic molecules in liquid water. Organic matter might have been formed in the primitive Earth's atmosphere o...

The D/H variations in chondritic meteorites are reviewed and compared with astronomical observations in the interstellar medium. The observed D enrichment in organic molecules — and to a lesser extent in water — is a general rule in the universe. The D is preferentially transferred from the universal reservoir (H2) by low-temperature reactions (10–100 K) from neutral molecules (H2 or H) to hot ...

Mechanical representations of the solar system have been around for thousands of years. The human fascination with the night sky has been recorded in every culture as far back as documented time. This paper proposes a method for motivating STEM through the development of two orrery systems both of which have unique characteristics that provide their own teaching methods to students and adults a...

Ice is ubiquitous in the solar system; it is also a substance with a fascinatingly complex set of transitions between its multiple forms. Here I review what is known of the various crystalline and amorphous phases of ice, and of their presence on different solar system bodies,

solar flare events of high importance were utilised to study solar latitudinal frequency distribution of the solar flares in northern and southern hemisphere for the solar cycle 22 to recent solar cycle 23. a statistical analysis was performed to obtain their relationship with sudden storm commencement (sscs) and forbush decrease events (fd) of cosmic ray intensity. an 11-year cyclic variation ...
