Sony will be soon exhibiting its cordless speaker system and cell phone chargers that are powered by its direct methanol fuel cells (DMFC) , where the fuel methanol is located within a transparent tank. A lithium ion secondary battery is used to compensate for low outputs of tiny DMFCs, enabling mobile devices to handle steep current peaks without any detrimental effect. The cell phone chargers rely on USB connectivity to keep your precious handsets juiced up .
NTT Energy and Environment Systems Laboratories developed a circuit module that enables the charge of a lead storage battery with a single photovoltaic cell . The circuit module consists of a boost circuit with a DC-DC converter and an IC equipped with the "MPPT (maximum power point tracking)" function. The boost circuit can increase the typical voltage of a single photovoltaic cell, about 0.5V, up to 15V.

Collexis Holdings, a leading developer of semantic search and knowledge discovery software, launched the world's first Hydrogen Fuel Knowledge Dashboard through a partnership with Thomson Reuters and the University of South Carolina.
Peter Russo and Brendan Wypich of Stanford University developed the SmartSwitch , a light control with tactile feedback that helps you "see" how much energy is already being used, whenever you try to flick the switch. If the total energy consumption in the house is low, the SmartSwitch is easy to flip. But if the consumption is higher, the SmartSwitch is physically harder to flip, thanks to a brake pad within the mechanism. The idea is that people will use this tactile feedback to decide if they really really need that light on or not.

Los Gatos, CA: SunPods Inc. and SBM Solar Inc., two companies experienced in the photovoltaic industries respectively, announced today a new strategic alliance to develop new impact resistant solar modules for SunPod's transportable modular photovoltaic arrays for use in high risk environments
PG&E Strengthens Leadership Role with Announcement of Significant New Solar Program
NRG Energy, one of the United States' most coal-dependent utilities, on Monday signed a deal with California startup eSolar to develop solar power plants. The agreement calls for NRG to invest $10 million in Pasadena-based eSolar for the right to use the startup's technology to develop and operate three solar power projects in California and the Southwest that would generate 500 megawatts of greenhouse gas-free electricity. NRG ranks as one of the nation's dirtiest utilities, spewing 70 million tons of carbon dioxide annually from its coal-fired power plants. eSolar will use fields of mirrors to heat water to create steam that drives electricity-generating turbines.

PowerGrip Plus Roof Mount System, a watertight structural attachment system used to secure ballasted solar racks and other equipment to roofs covered with thermoplastic (TPO and PVC) membranes. PowerGrip Plus is designed with wind performance in mind and offers ultimate tensile strength of 2,000 lbf. and ultimate shear strength of 1,075 lbf. Properly installed PowerGrip Plus units reduce rack movement and remaining watertight. PowerGrip Plus units are easy to install, saving both time and labor when compared to alternative options. A wide membrane skirt promotes easy welding in place, and the 15/8 diameter and 1/2 inch tall mount provides an optimal perch for securing brackets or struts. The exposed 1 inch tall and 3/8 inch diameter bolt and mounting stand are made from corrosion-resistant stainless steel and aluminum alloy for superior long-term performance.
