We have been extending and refining our model of vacuum breakdown and gradient limits and describe recent developments. The model considers a large number of mechanisms, but finds that vacuum arcs can be described fairly ...

Lithium ion batteries have become the main stream for energy storage; however, its toxicity, poor durability (≤5 years) and high cost (≥USD2.35/Wh every 25 years), along with the safety issues (very high degree of reactivity ...

Photovoltaic (PV) power systems are the fastest growing green technology. Integration of PV in the urban environment is a promising technology that can lead to a construction of Zero Energy Buildings or nearly Zero Energy ...
