Rawlemon’s Spherical Solar Energy-Generating Globes Can Even Harvest Energy from Moonlight The solar energy designers at Rawlemon have created a spherical, sun-tracking glass globe that is able to concentrate sunlight (and moonlight) up to 10,000 times. The company claims that its ß.torics system is 35% more efficient than traditional dual-axis photovoltaic designs, and the fully rotational, weatherproof sphere is even capable of harvesting electricity from moonlight. The ß.torics system was invented by Barcelona-based German Architect André Broessel. He sought to create a solar system that could be embedded in the walls of buildings so that they may act as both windows and energy generators. The spheres are able to concentrate diffused moonlight into a steady source of energy. + Rawlemon Via Designboom
Key RTP Facilities | Ensyn Multiple RTP facilities with commercial scale operations Ensyn’s First dedicated Biofuels Plant Renfrew, Ontario Ensyn’s plant in Renfrew, Ontario is its first facility dedicated to the production of advanced cellulosic biofuels. The Renfrew plant has been in operation since 2006, focused primarily on production of liquids and heating fuels for the speciality chemicals industry. In addition, Ensyn has used the Renfrew facility to demonstrate and commercialize its biofuels business. The Renfrew facility has now been converted to a dedicated RFO™ biofuels facility. In conjunction with this conversion, production capacity is being increased to thee million gallons/year, with project completion targeted for mid-2014. Red Arrow RTP Facilities Rhinelander, Wisconsin Red Arrow, Ensyn’s partner in the food chemicals business, owns and operates five commercial RTP plants in Wisconsin. Petroleum RTP Facilities Three RTP facilities have been constructed and operated for heavy oil upgrading.
Solar Energy is capable of powering Australia. Solar Energy is capable of powering Australia. “The Magazine of Engineers Australia”, Vol 80, No. 9, Sept 2008, page 20 “Economically viable Power from the Sun Half of Australia’s renewable energy target could be generated from solar power by 2020, according to engineering services company WorleyParsons. Meurs said the company’s research has found that Australia’s desert regions would be ideal locations for such plants and the optimal size would be 250 Mega Watts. The company invited potential customers to participate in a feasibility study and received a very favbourable response, Meurs said. The proposed technology would be parabolic mirrors focusing sunlight onto tubes containing thermal oil. The plants would cater for power demand during the day, with some heat storage capacity in molten salt to cover the evening. Each solar plant would require no more land than a conventional coal fired power station. Anti-renewables = anti-business. Pro nuke = anti small businesss with local control.
PK Clean: Pioneering a Better Way to Recycle You may feel good when you put your empty soda bottle in the recycling bin, but traditional recycling is a highly inefficient process. Because there isn't much of an infrastructure for recycling plastics other than PET--the plastic found in soda bottles--plastic is a hard thing to get rid of. In 2012, there were 32 million tons of plastic waste generated in the United States, according to the Environmental Protection Agency. PK Clean thinks it has the answer. In 2010, she set up a pilot plant in Pune, India, in which she ironed out the kinks in the process. Last summer, using savings and money from contests, including $20,000 from the Cartier Women's Initiative, they built their first commercial-scale plant in Salt Lake City.
Up on the Roof By Michael Brune, Sierra Club’s Executive Director Let me start with a confession: I’m the executive director of the country’s largest environmental organization, and I don’t have solar panels on my roof. Now wait a minute. Before you judge, I do have a few justifications. Until now. Last year, the Sierra Club ran a pilot program in California to spread the news to our members and supporters that there’s never been a better time to add solar panels to their roofs. Our pilot program was successful enough that we’re expanding it to seven states: Arizona, California, Colorado, Connecticut, Maryland, Massachusetts, and New York. But the economics are far from the only reason you should check out solar leasing. If you’re interested in being a part of the Sierra Club’s program, the first step is to do what I did: Request a solariQuote. Once you supply some data on your utility bills, you can find out exactly how much you can expect to save (based on the plan you choose). Related Stories:
Waste-to-energy technology is cleaner and safer than generally believed When we think of climate-change deniers, Tea Partiers and Republicans often come to mind. But some of the most troubling stumbling blocks to reducing greenhouse gases come from urban liberals and left-leaning environmental groups who oppose burning municipal solid waste to produce energy. In California, when new waste-to-energy plants (WTEs) are proposed, they run into buzz saws of liberal opposition. Plans to increase the volume of waste burned at a Minneapolis WTE facility have been blocked for four years, and the issue recently divided the Democratic candidates for mayor. From New York to Massachusetts to Rhode Island to Pennsylvania to Maine, opposition has delayed or stopped WTE plants across the nation, largely in liberal-controlled urban areas. But the opposition is misguided. Source: Covanta Energy, one of the two major US WTE operators. Reduce, reuse, recycle — and then what? Liberals, overwhelmingly, are choosing to dump, which science shows is the most polluting alternative.
The Solar Trade War Demystified NOTE: This is a guest post by Erica Etelson, a blogger for Mosaic, an online marketplace for investing in solar. Follow her at @iluvsolar. Recently, the U.S. Commerce Department imposed tariffs on $3 billion a year worth of Chinese solar panel imports. Non-Chinese solar panel manufacturers contend that China is able to “dump” cheap panels on the global market thanks to lavish Chinese government subsidies. It’s a complicated, wonky issue even for solar geeks like me, and there are compelling policy justifications for and against the tariffs. Solar Tariffs: The Pros - The Chinese solar industry is undermining US solar manufacturing by flooding the market with cheap panels, and tariffs could help level the playing field. - Instead of dumping panels on the global market, China can and should install them domestically. - Cheap PV panels stifle innovations like thin film solar.

Seminar - WTERT-Ghana Sustainable Waste Management in Africa Accra, Ghana, May 26th-30th, 2014 The Earth Engineering Center (EEC) of Columbia University in collaboration with WTERT/Greece and the Institute of Sanitation & Waste Management (ISWM) of Ghana are pleased to announce that an interdisciplinary course and workshop will take place in Accra, Ghana, at the campus of KNUST-ISWM (May 26th-30th, 2014). This 5-day intensive course will focus on state of the art technologies for advancing sustainable waste management in Africa and will encompass the full hierarchy of waste management from materials recovery (recycling) to energy recovery (Waste-to-Energy or WTE), and sanitary landfilling with methane capture. The organizing committee for this course are Prof. Participants will receive a certificate of continuing education by the Earth Engineering Center of Columbia University.

The GreenSky project will see BA commit to buy all 50,000 tonnes of jet fuel produced at the processing facility for at least 11 years. The plant, operated by Solena Fuels, is to be built by 2017 on the site of the former Coryton oil refinery, creating 150 permanent jobs. BA said the facility would be the world's first to convert landfill waste into jet fuel. Solena Fuels has been developing the project, which will use its own patented technology alongside current techniques to convert everyday waste into gas and then into a range of liquid fuels.
