Chernobyl is to become the world's largest solar power plant
ALEXANDRU MICU for ZME Science: The Ukranian government plans to turn Chernobyl, the site of the world’s most famous nuclear meltdown, into a sprawling solar power plant — the largest in the world.
Since the meltdown on April 26, 1986, no one’s been able to find any good uses for Chernobyl. A 1,600 square mile area was drenched in radiation and deemed an “exclusion zone,” so everyone was evacuated after the clean-up efforts were concluded and the plant was sealed in its ubiquitous sarcophagus. The buildings, goods, and infrastructure in the area were abandoned so fast that the city looks like time froze there 30 years ago — albeit with a Falloutesque look. Since we left, nature took over, and for the most part, is thriving in our absence (though the microbes that decompose dead organic matter seem to be having a hard time living here.)
In a recent interview, however, Ukraine’s ecology minister Ostap Semerak said that the government is negotiating with two US investment firms and four Canadian energy companies to develop Chernobyl’s solar potential. The area is uniquely suited for the purpose — the land is extremely cheap, much of the required infrastructure, such as roads are already built. Even better, the power lines that served the old 4GW reactor are still useable. Cont'd...
Tesla Lowers Bid, Agrees to Pay $2.6 Billion for SolarCity
Chris Martin for Bloomberg Technology: Elon Musk’s Tesla Motors Inc. reached an agreement to buy SolarCity Corp. for $2.6 billion, about $300 million less than an initial proposal criticized as a “bailout” for the solar company in which he’s the largest shareholder.
SolarCity investors will receive $25.37 a share in stock under the agreement, according to a statement Monday. Musk initially offered $26.50 to $28.50 a share in Tesla stock. Analysts have said in the past that the bid was too low and investors have questioned the wisdom of Musk combining his electric-car maker with the clean-energy company. The deal, which allows SolarCity to solicit competing takeover offers through Sept. 14, will now go to the shareholders of the companies for approval. Cont'd...
Molten storage and thermophotovoltaics offer new solar power pathway
Georgia Institute of Technology: New computer modeling suggests that high temperature TPV conversion -- which captures infrared radiation from very hot surfaces -- could one day rival combined-cycle turbine systems when combined with thermal storage using liquid metal at temperatures around 1,300 degrees Celsius. Advances in high-temperature components and improved system modeling, combined with the potential for conversion costs an order of magnitude lower than those of turbines, suggest that TPV could offer a pathway for efficiently storing and producing electrical power from solar thermal sources, a new study suggests.
The underlying technologies of high temperature storage and thermophotovoltaic conversion could also be used to produce grid-scale batteries able to rapidly supplement other power sources by storing heat for quick conversion to electricity. The research, supported by ARPA-E, was reported July 4 in the journal Energy and Environmental Science by researchers at the Georgia Institute of Technology. Cont'd...
Flight to the future: Solar Impulse shows we can run the world without consuming the earth
The lessons of Solar Impulse are clear: by pushing the boundaries of technology, and refusing to accept limits, technological or psychological, we can run the world without consuming the earth, and reach heights we never believed were possible.
Using Particle Accelerator Technology to Manufacture Solar Cells
This technique is projected to reduce solar panel manufacturing costs by upwards of 60% compared to industry standards, while making them 25% more efficient, and resulting in a very cost-effective source of energy.
Belgian scientists make novel water-from-urine machine
Reuters: A team of scientists at a Belgian university say they have created a machine that turns urine into drinkable water and fertilizer using solar energy, a technique which could be applied in rural areas and developing countries.
While there are other options for treating waste water, the system applied at the University of Ghent uses a special membrane, is said to be energy-efficient and to be applicable in areas off the electricity grid.
"We're able to recover fertilizer and drinking water from urine using just a simple process and solar energy," said University of Ghent researcher Sebastiaan Derese.
The urine is collected in a big tank, heated in a solar-powered boiler before passing through the membrane where the water is recovered and nutrients such as potassium, nitrogen and phosphorus are separated. Cont'd...
Turbines for First U.S. Offshore Wind Farm
The Maritime Executive: Preparations for the groundbreaking Block Island Wind Farm – America's first – are well under way, with the regulatory permits obtained, the funding procured and the jacket installation complete. Now the actual equipment for the farm, towers, blades and five massive turbines have been shipped, ready for assembly.
The blades arrrived in Providence, RI from Denmark on the general cargo shipSuomigracht late last month, and the turbines are on board the Fred Olsen jackup construction vessel Brave Tern, currently under way across the North Atlantic. When theTern arrives, it will begin the process of installing the towers; that work is expected to begin in August.
The 20-mile cable connecting Block Island with the mainland was completed on June 28 – providing the island with its first electrical and fiber optic connection ever. Deepwater Wind, the developer and operator of the farm, has completed a separate cable linking the facility with Block Island, and expects to finish cable linkages between the five wind towers this month.

Why flying a kite could be the future of clean energy
Antony Michels for Yahoo Finance: David Schaefer wants to sell $50,000 kites to farmers to help them generate electricity by harnessing the power of the wind.
Schaefer, 54, is the CEO of eWind Solutions, a Beaverton, Oregon, company he founded in 2013 after quitting his job as director of mechanical engineering at Xerox.
“Imagine when you were a kid in a field flying the kite,” Schaefer says. “When the wind picks up you remember feeling that pull on the string. Well that pull is really energy. That’s what we’re doing. We’re harnessing that energy.” Cont'd...
Can We Place Solar Panels in Space?
Since clouds, atmosphere and nighttime are absent in space, satellite-based solar panels would be able to capture and transmit substantially more energy than terrestrial solar panels.
Obama makes new push on solar power
Timothy Cama for The Hill: The Obama administration is making a new large-scale effort to encourage deployment and use of rooftop solar power on homes.
Numerous agencies announced new or strengthened coordinated efforts Tuesday aimed at increasing solar installations in houses owned by low- and moderate-income Americans, including a new goal for solar installations and a policy change to increase access to a key financing mechanism for solar power and energy efficiency.
“This is an approach that cuts across the government to try to take advantage of the fact that the cost of renewable technologies has come down dramatically during President Obama’s tenure, and we want to advantage of that a try to encourage more homeowners to actually benefit directly from that dynamic,” Brian Deese, a top adviser to Obama, told reporters.
The administration is dubbing the effort the “Clean Energy for All Americans Initiative.” Cont'd...
Clean Energy Investment in 2016 Undershoots Last Year's Record
Investment slowdowns in China and Japan, as well as further reduction in the cost of solar, mean 2016 investment will fall well short of 2015's upwardly revised $348.5bn
Africa's Off-grid Solar Market Is Booming
Investors will need to understand the differences between on-grid and off-grid solar. And a long term proof of bankability of the off-grid solar sector is still needed.
Why Drones Are 'Game-Changing' for Renewable Energy
Julia Pyper for GreenTechMedia: Amazon caused quite the stir in 2013 when it announced plans to launch a drone delivery service. People were both thrilled and horrified at the thought of flying robots delivering toilet paper to our doorsteps.
Some drone enthusiasts hoped to see Amazon launch a drone-based solar installation service -- but alas, that business doesn't exist. Yet.
Drones are already disrupting the solar sector, however.
This week at Intersolar North America, DroneDeploy, a cloud software platform provider for commercial drones, and DJI, a leading maker of drones and camera technology, announced a partnership that is expected to dramatically increase the efficiency of solar panel installation and inspection using drone-based thermal imagery capture and analytics.
The companies claim that customers can reduce residential solar system measurement times by up to 50 percent and reduce commercial measurement times from days to minutes. In addition, on-board thermal imagery can help to ensure that equipment is in the optimal position for maximum production. Cont'd...
