72 A grade 3x6 solar cell kit for DIY solar panel DIY solar cells are the cheapest way to generate electricity from the sun for small projects. Building panels from solar cells is highly educational - both electrically and mechanically - and provides days of fun in the sun for those of us who like to build for the sheer pleasure of it. They are also versatile, as you can customise your voltage/current to suit your needs in a way that is impossible with pre-assembled panels. PV cells have a rated lifetime of +20 years if they are maintained and housed correctly. KnowYourPlanet have sold over 1 million solar cells to date, so you can trust us to supply solar cells which work and are sourced from trusted manufacturers in Europe. We recommend that you mount the cells effectively to ensure a long lifetime, low corrosion and cracking. If you are looking for bigger installations please don't hesitate to contact us, we also have a wide range of solar panels, inverters, batteries and much more available at very competitive prices.

Brilliant SUNplace table beams solar energy on a cast iron cooking surface | Inhabitat - Green Design, Innovation, Architecture, Green Building The Sunplace is a concept piece created by an Italian and Singaporan brings together the couple’s diverse perspectives to create a practical and inspiring BBQ tool for social gatherings. Solar-powered cooking devices are typically pretty simple; there aren’t a lot of steps needed to convert sunbeams into cook-worthy energy, just a little concentration. In the Sunplace, an adjustable fresnel lens heats the cast iron cooking surface, concentrating the sun’s energy and directing it where it needs to go.

Milan's Vertical Forest Wednesday, 12 October 2011 GreenMuze Staff Milan’s Vertical Forest from Stefan Boeri Architects. The Bosco Verticale (Vertical Forest) will be the greenest building in Milan when completed, which is one of Europe’s most polluted cities. Designed by Stefan Boeri Architects, as part of their BioMilano vision to incorporate 60 abandoned farms into a greenbelt surrounding the city. The Bosco Verticale building has a green façade planted with dense forest systems to provide a building microclimate and to filter out polluting dust particles. The living bio-canopy also absorbs CO2, oxygenates the air, moderates extreme temperatures and lowers noise pollution, providing aesthetic beauty and lowering living costs. Each apartment balcony will have trees (900 plantings are planned for the two buildings) that will provide shade in the summer and drop their leaves in winter to allow in winter sunlight.

Solar panel roads 'could solve energy crisis' Asphalt roads and car parks would be torn up and replaced with glass solar cell panels capable of generating enough power to support local communities, under the scheme. A US firm is currently working on a prototype panel that could be embedded into existing roads, having won a $100,000 grant from the US Department of Transportation. The panels would also be covered with a mosaic of small lights, which could be illuminated to provide road markings and warning messages to drivers. They could also be embedded with heaters to keep the road clear by melting snow and ice. With each 12 ft by 12 ft panel capable of producing 7.6 kilowatt hours of power each day, the company Solar Roadways calculates that resurfacing the entire US interstate highway network would meet the country's energy needs three times over. A four-lane, one-mile stretch of road made from the panels could generate enough power for 500 homes, it claims.
GoSun Grill: A Breakthrough Solar Oven that Cooks at Night by Patrick Sherwin Risks and challenges Timeline: We refuse to compromise on the quality of our products. During the manufacturing process of the GoSun Sport in early 2014, we established an extensive quality assurance plan, which caught some mistakes, and in turn, delayed the fulfillment of our product for months. We’ve learned to be extremely accurate and completely transparent with our backers regarding the latest developments. Shipping: The GoGun Grill is going to need additional package design and engineering to ensure safe transport to your home. This is entirely GoSun's concern since you’re covered with a Two-Year No Questions Asked Warranty on the evacuated tube. Battery Costs: We have not fully defined our costs on the Thermal Battery encapsulation vessel and production costs. Social Media Sharing: As a small start-up business, we depend heavily on the word-of-mouth and enthusiasm of our customers. Learn about accountability on Kickstarter
Tech Talk - Tensions Over Oil in the South China Sea Posted by Heading Out on August 12, 2012 - 4:39am Topic: Supply/Production Tags: brunei, china, malaysia, oil reserves, oil rig, paracel islands, philippines, south china sea, spratly islands, taiwan, thailand, vietnam [list all tags] In the introductory remarks to these posts on Chinese energy supplies and usage, I mentioned that one of the concerns beginning to be evident lies in disputes over the ownership of some of the oilfields offshore. Disputes over ownership have been continuing for some time, and this week was no exception, with Chinese moves to create a new city, Sansha, on Woody Island and thereby strengthen their claim to the region. Woody Island, or Yongsing, lies in the Paracel chain of islands in the South China Sea. (The post has been slightly modified to recognize the speculative nature of the overall resource available.) Figure 1. Figure 2. Figure 3. In 1988, the Chinese and Vietnamese navies exchanged shots at Johnson reef (video here) with Vietnam losing three ships.

Neuartiger Kühlschrank benötigt keinen Strom Seit dem Jahr 2012 arbeitet ein Berliner Start-Up Unternehmen an einem Kühlschrank der ohne Strom auskommt. Bereits Ende dieses Jahres sollen die ersten 50 Modelle ausgeliefert werden. © Coolar Berlin (Deutschland). Kühlschranke finden sich nahezu in jedem Haushalt und tragen viel zum täglichen Stromverbrauch bei. Während ein herkömmlicher Kühlschrank Kühlmittel und Strom benötigt, so braucht der sogenannte Coolar nur Wärme, die anschließend in Kälte umgewandelt wird. So funktioniert der Kühlschrank ohne Strom Der Coolar arbeitet mit Hilfe des sogenannten Verdunstungskälteeffekt. Kieselgel-Kugeln nehmen Wasserdampf auf und geben dabei Wärme ab bzw. der Umgebung Wärme entziehen, wenn sie trocknen. Coolar soll die Welt verbessern Das Unternehmen kooperiert eng mit der Organisation Ärzte ohne Grenzen.
