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
Primus Green Energy’s STG+ patent for liquid fuel synthesis from syngas approved Primus Green Energy’s STG+ patent for liquid fuel synthesis from syngas approved Primus Green Energy Inc., an alternative fuel company that converts natural gas and other feedstocks directly into drop-in transportation fuels and solvents (earlier post), announced that its patent application covering its STG+ liquid fuel synthesis technology has been allowed by the US Patent and Trademark Office (USPTO). STG+ produces high-quality, cost-effective, drop-in liquid transportation fuels directly from syngas derived from natural gas and other carbon-rich feedstocks in a single-loop process. STG+ essentially improves upon commercial methanol synthesis processes and ExxonMobil’s methanol-to-gasoline (MTG) process, combining them into an integrated, optimized system that efficiently converts syngas directly to fuels. Primus says that STG+ represents a cost breakthrough for the GTL industry, as it demonstrates compelling economics at scales of less than 6,000 barrels per day. Resources
Transformer l’énergie cinétique des métros en électricité Par Gerome 0 Mardi 6 septembre 2011 2 06 /09 /Sep /2011 09:23 - Publié dans : Les bonnes nouvelles Paris, New-York (Etats-Unis), Londres (Grande-Bretagne). Qu’est-ce que ces villes ont notamment en commun ? D’après les ingénieurs de l’entreprise californienne Vycon Energy, il serait en effet possible de récupérer l’énergie cinétique des rames de métro et des trains légers et de la transformer en électricité. Celle-ci est toutefois automatiquement perdue au moment de la décélération. « Quand le train voudra partir, il suffira d’utiliser l’énergie créée précédemment », résume le vice-président de Vycon Energy Louis Romo, selon lequel un métro composé de dix voitures nécessiterait une décharge comprise entre trois et quatre mégawatts (MW) pendant trente secondes pour regagner sa vitesse de croisière. L’alternative paraît tout à fait plausible, d’autant qu’elle est proposée par une entreprise leader dans le secteur du recyclage de l’énergie cinétique.
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.
Westinghouse Plasma Concept ecolo pour valoriser le bruit ... Un concept écolo, imaginé par le designer Hung-Uei Jou, visant à transformer le bruit en énergie … Le concept Green noise a été imaginé pour les aéroport (lieu souvent très bruyant) … l’idée est en faite de convertir le bruit environnant en énergie. Energie durable qui pourra être utilisée pour assurer l’éclairage des pistes ! Une idée surprenante mais fort intéressante; car les aéroport sont en effet source de grosse pollution auditives (qu’ils serraient sympathique de voir valorisées), et c’est aussi des lieux de consommation énergétique important (et toutes solutions permettant de réduire la consommation énergétique de ce genre d’endroit est bonne à prendre, ou du moins à étudier) … Un petit bémol concernant la présentation de ce concept, impossible de trouver des informations sur le fonctionnement du procédé … je vous mets donc à contribution, si vous savais comment l’on transforme du bruit en energie renouvelable ?

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:
