Lighting energy represents 30-40% of commercial building electricity consumption, yet very few buildings have advanced lighting controls. The potential energy savings are tremendous as is the opportunity to reduce demand on the grid during critical peak use periods. Charlie will describe how low-cost wireless radio technology develop at UC Berkeley ...
Enhancing thermodynamic efficiency and reducing kinetic losses through size effects can improve energy conversion. I will discuss bandgap tuning for light absorption in solar cells and reducing activation overvoltage as well as ohmic lossesin fuel cells:(1) I will report on the deposition of Lead sulfide (PbS) thin films by atomic ...
