C This paper provides a design outline and implementation procedure for a Secondary Energy Storage Unit (SESU) that can be used to meet the peak energy requirements of an electric vehicle during both acceleration and regenerative braking. The life cycle of the electric vehicle’s batteries can be extended considerably by supplying peak energy requirements from a secondary source. A simulation st...

Health concerns associated with Legionnaires' disease have been identified as an area of the increasing public and professional interest. Any natural water or man-made water systems worldwide might be reservoirs of Legionellae. We presented a sporadic, community-acquired case of Legionnaires' disease caused by Legionellapneumophila serogroup 1 in a bus driver who used water for hand and face wa...

Many communities along the US-Mexico border remain without infrastructure for water and sewage. Residents in these communities often collect and store their water in open 55-gallon drums. This study evaluated changes in drinking water quality resulting from an intervention that provided large closed water storage tanks (2,500-gallons) to individual homes lacking a piped water supply. After the ...

Solar desiccant cooling is widely considered as an attractive replacement for conventional vapor compression air conditioning systems because of its environmental friendliness and energy efficiency advantages. The system performance of solar desiccant cooling strongly depends on the input parameters associated with the system components, such as the solar collector, storage tank and backup heat...

Fluctuations in renewable energy production, especially from solar and wind plants, can be solved by large-scale storage. One of the possibilities is storing form hydrogen or methane–hydrogen blends. A viable alternative for salt caverns Lined Rock Cavern (LRC) underground most significant challenges LRC storage sealing liners, which need to have satisfactory mechanical properties. An experimen...

A packed bed thermal storage has several desirable characteristics to be used for energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (K1), conduction effect (K2) and air capacita...

This work proposes a new device for air treatment with dehumidification and water recovery/storage, possible mitigation of indoor environmental conditions. The system is based on Peltier cells coupled horizontal earth-to-air heat exchanger, it proposed as an easy-to-implement alternative to the pumps handling units currently used market, in terms cost, ease installation, maintenance. process pr...
