It was found from the cooling performance simulation that in order to save 50% energy of the air conditioner, the required solar collector area is 40 m2 in Taipei and 31 m2 in Tainan, for COPj = 0.2. If the solar collector area is designed as 20 m2, the solar ejector cooling system will supply [...]

The efficient coupling between lattice degrees of freedom and spin degrees of freedom in magnetic materials can be used for refrigeration and energy conversion. This coupling is enhanced in materials exhibiting the giant magnetocaloric effect. First principle electronic structure calculations on hexagonal MnFe(P, Si) reveal a new form of magnetism: the coexistence of strong and [...]

Concentrating solar power (CSP) has the potential to become a leading sustainable energy technology for the European electricity system. In order to reach a substantial share in the energy mix, European investment in CSP appears most profitable in North Africa, where solar potential is significantly higher than in southern Europe. As well as sufficient solar [...]

To ensure sufficient thermoelectric power production in the future, the use of alternative water sources to replace freshwater consumption in power plants will be required. The amount of municipal wastewater (MWW) being produced and its widespread availability merit the investigation of this potential source of cooling water. This is particularly important for thermoelectric power plants [...]

The rules, which are subject to a 30-day period of public comment and a hearing on Feb. 28, would phase out the dirtiest types of heating oil used by about 10,000 buildings in New York: No. 6, the cheapest but most viscous type pumped into aging boilers, and another heavy oil, No. 4, which is [...]

This paper presents a novel design and the prototyped solar cooking stove which uses a large Fresnel lens for the concentration of sunlight. The technology demonstrates high safety and efficiency of solar cooking and heating using Fresnel lenses which are low cost and available from off-the-shelf. The stove has a fixed heat-receiving area located at [...]

Since heating and cooling systems of buildings consume 30–50% of the global energy consumption, increased efficiency of such systems means a considerable reduction in energy consumption. Ground source heat pumps (GSHP) are likely to play a central role in achieving this goal due to their high energy efficient performance. The efficiency of GSHP depends on [...]
