California's First Commercial Solar Desalination Plant Offering Shares Through DPO
Derek Markham for CleanTechnica: The company behind what will be California’s first commercial-scale solar desalination plant is issuing $10 million in preferred stock in the venture, through a state-registered direct public offering (DPO) in California.
WaterFX Hydro I, Inc., doing business as HydroRevolutionâ„ , a California subsidiary of WaterFX™, is offering the shares to finance the construction of a fully solar-powered desalination plant in the Central Valley, which is expected to be able to produce up to 1.6 billion gallons (5000 acre-feet) of water per year, with virtually zero liquid discharge. The HydroRevolutionâ„ process is said to allow for a 90% recovery rate, with the remaining brine being treated further to isolate the salt and mineral byproducts for industrial applications.
Instead of desalinating seawater, as many desalination operations do, this plant will pull water from shallow irrigation water (also called subsurface drainage water) which is produced as a consequence of agriculture, and which has a high salinity content that can be detrimental to freshwater ecosystems. This new plant is a scaled up and expanded version of the company’s demonstration desalination plant. Cont'd...

Tesla And Panasonic Fight "Battery War" In Europe
By Vlad Tverdohleb for CruxialCIO: Panasonic Corp is the producer of lithium-ion batteries for Tesla Motors Inc’s cars. However, Panasonic is now preparing to begin selling batteries that power homes in Europe. Its first market is Germany, where homeowners are even given greater incentives to switch to clean electricity generated by solar-power devices.
Thus, Panasonic’s push into international markets with home batteries is putting the Japanese company into direct competition with Tesla, its flagship customer. In May, the American company unveiled a suite of batteries to store electricity for businesses and homes.
Panasonic plans to move later to France, the U.K. and other European markets. Laurent Abadie, Panasonic Europe chief executive officer, declared on Wednesday, Sept. 2, in an interview at the IFA International Consumer Electronics Show in Berlin, that the company has not decided yet when it would start sales in Europe.

New in Cold Nuclear Fusion
Today we know that not only the first isotope of hydrogen (deuterium) produces fusion energy, but also the second (heavy) isotope of hydrogen (tritium) can produce energy by nuclear fusion.
Five Myths About Solar Power - And The Real Facts
What we are witnessing is in reality a traditional consolidation phase in a new and fledging industry, with winners and losers, and with the surviving players facing a bright and profitable future.
Solar windows can power buildings
By Lucas Mearian for Computerworld: Manhattan has approximately 47,000 buildings with around 10.7 million windows, according to a 2013estimate from The New York Times.
Now imagine if just 1% -- or 100,700 -- of those windows could generate electricity through transparent photovoltaics.
That's the idea behind solar power windows, and at least two companies are hoping to sell the technology to window manufacturers, saying once installed in a building the technology will pay for itself in about a year.
"If you look at the glass that's manufactured worldwide today, 2% of it is used for solar panels; 80% of it is used in buildings. That's the opportunity," said Suvi Sharma, CEO of solar panel maker Solaria. Cont'd...
How floating turbines could harness the awesome power of the tides
Ross Jennings for The Conversation: The world’s tides contain enough energy to power the entire UK’s electricity consumption. And, since it effectively harnesses the moon’s constant and predictable gravitational pull, tidal power overcomes one of renewable energy’s classic problems – the fact you never know quite how much sun, wind or rain to expect. Now, underwater windmills positioned just below the ocean surface could be a major breakthrough for tidal power.
Costly technology and inaccessible locations have thus far held things back. Large, heavy and expensive turbines mounted on the seabed have been developed, but these are aimed at commercial scale developments. Tidal power needs its equivalent of the rooftop solar panel.
Imagine then a wind turbine, but underwater, and not fixed to the seabed – these so-called “mobile floating turbines” are a cheaper and more adaptable alternative to big, fixed developments. Most floating turbines look something like this: Cont'd...
Key Challenges Google's Project Sunroof May Face
Whether Googles Project Sunroof will be a hit or a miss, only time will tell. Nevertheless, the technology is brilliant and this move from Google could make this firm a leading one in the global solar industry.
Concentrator Photovoltaics: The Next Step Towards Better Solar Power
By Lauren J. Young for IEEE Spectrum: Today’s concentrator photovoltaic (CPV) technologies have shown promising potential for more efficient solar power. The latest systems are said to be capable of handling the power of a hundred suns. Yet prototypes have failed to compete with cheaper flat panel solar systems that dominate the market. The U.S. Department of Energy’s Advanced Research Projects Agency (ARPA-E) is determined to push CPV to the next level. On 24 August, at the Clean Energy Summit, U.S. President Barack Obama and Energy Secretary Ernest Monizannounced a program called MOSAIC that will invest $24 million into CPV solar technology development.
Why can’t today’s CPV systems compete? The concentrators can only convert direct sunlight into energy, missing out on the large fraction of sunlight diffracted by clouds and the atmosphere. Manufacturing costs of concentrator apparatuses have also prevented CPV from reaching mass production. Cont'd...

NASA Seeks Proposals for Extreme Environment Solar Arrays
NASA's space technology program is seeking proposals to develop solar array systems for space power in high radiation and low solar energy environments.
In the near future, NASA will need solar cells and arrays for multiple applications in robotic and human space exploration missions. Because these systems were traditionally developed for operation near Earth, there is a need to develop new solar array concepts as NASA considers missions that require exposure to more intense radiation environments and travel ever farther from the sun.
NASA hopes to solicit proposals for the development of promising technologies to increase solar cells that will work under low intensity, low temperature and high radiation environments.
Proposals will be accepted from U.S. organizations, including NASA centers and other government agencies, federally funded research and development centers, educational institutions, industry and nonprofit organizations.
Iran is building the Middle East's first geothermal power plant
Iran is building the Middle East’s first geothermal power plant at the foot of an inactive volcanic peak as the country is racing to meet a runaway demand for electricity by its growing population.
The pilot station in northwestern Meshguin Shahr in the Ardabil province is projected to come on stream in the next two years, putting Iran in the club of two dozen nations with the geothermal power generation capacity.
The 50-megawatt project is in line with Iran’s bid to expand its clean energy mix which is dominated by fossil fuels. Geothermal power is cheaper and more reliable than other renewable energy sources, such as thermal or hydro power. Cont'd...
