The use of photovoltaic (PV) cells in domestic and industrial applications has grown rapidly through the recent years. Constructing PV plants is a very smart measure to produce free electricity in large scales, especially in the countries with higher solar irradiation potential. On the other hand, compressed air energy storage (CAES) has already been proposed to be employed for energy storage a...

This paper describes modeling and simulation of air compressor energy use to estimate energy savings in compressed air systems from air use reduction and other changes. The method uses measured power signatures and other compressor parameters as inputs to calculate various performance metrics and estimate energy savings. To enable recognition of control mode from measured power data, examples o...

This study presents an experimental investigation of a piston engine driven by compressed air. The compressed air engine was a modified 100 cm 3 internal combustion engine obtained from a motorcycle manufacturer. The experiments in this study used a test bench to examine the power performance and pressure/temperature variations of the compressed air engine at pressures ranging from 5 to 9 bar (...

As an important solution to issues regarding peak load and renewable energy resources on grids, large-scale compressed air energy storage (CAES) power generation technology has recently become a popular research topic in the area of large-scale industrial energy storage. At present, the combination of high-expansion ratio turbines with advanced gas turbine technology is an important breakthroug...

Anaesthesia was given from a Boyle's apparatus to 100 patients, using compressed air as the carrier gas.

World wind energy resources are substantial, and in many areas, such as the US and northern Europe, could in theory supply all of the electricity demand. However, the remote or challenging location (i.e. offshore) and especially the intermittent character of the wind resources present formidable barriers to utilization on the scale required by a modern industrial economy. All of these technical...
