Champion Nano-Rust for Producing Solar Hydrogen
At the end of last year, Kevin Sivula, one of the collaborators at the LPI laboratory, presented a prototype electrode based on the same principle. Its efficiency was such that gas bubbles emerged as soon as it was under a light stimulus. Without a doubt, the potential of such cheap electrodes was demonstrated, even if…

Thin-Film Solar Cell Approaches Efficiency Record
A Copper Zinc Tin Selenide (CZTSe) solar cell technology has achieved an efficiency of 9.7% and an open-circuit voltage of 0.41 volts, a bit less than the 0.5 volts that most silicon-based solar cells achieve. (Solar cells are generally connected in series, which multiplies their voltage by the number of cells in the series connection.)…

Extraordinary Solar Light Now Available for Off-Grid Victims of Energy Poverty
This is a low-priced ($39.00) and sustainable light that some 25 percent of the world’s population – living off the grid – needs. Why? So dangerous kerosene lamps can be relegated to museums only. The following mission statement comes from WakaWaka designers and manufacturer of what the company contends is the “most efficient solar lamp…

Wind Power Forecast: Industry Will Add Over 241 Gigawatts of Capacity from 2012 to 2017
With the addition of 44.9 gigawatts in new installations in 2012, world wind power capacity grew to approximately 285.7 GW, an increase of 18.6 percent in the total wind power installation base. Average annual growth over the past 5 years has been 17.8 percent, achieved during the aftermath of the 2008 financial crisis, even with…
