Assuming an expected lifetime of 15 years, the described system amortises itself from the 4th year. The scaled annual production of 15,443.16 kWh offers enough potential to include private households as well as the local fishing industry in the power supply. This off-grid hybrid system was able to supply an average of 42.31 kWh of energy per day, with the daily demand of the key infrastructure successfully connected in the project, such as the local hospital and school, amounting to 18.75 kWh. In this article, we present the use of a photovoltaic system in conjunction with a 85 kWh second life lithium-ion battery (LIB) as an off-grid hybrid system to electrify an island in Lake Victoria in Tanzania as a socio-economic case study. In order to supply remote areas with electricity, off-grid system technologies have become increasingly common in recent years. Despite various national and international activities and expansion programmes, and a wide variety of actors, their implementation is progressing slowly. An essential key to this is electrification. If you’re interested in picking up a second language, visit Languagelab in Second Life, on Language Lab Island, or see their website.Socio-economic development in the rural regions of Africa cannot succeed without suitable infrastructure. The company has 11 full-time employees in London, eight teachers and an instructional designer plus 20-30 part-time staff populating the City and providing technical support, Second Life skills training and voice set-up. David also plans to launch additional courses in 2009 including a 10 week elementary Spanish course. Beginning in 2009 full courses will begin, and allow students to pay by the course or to maintain a subscription. They also take structured classes in the classroom. Today Languagelab’s students pay a monthly subscription which gives them access to the City where they practice under teacher supervision to increase fluency. The company has also built a specific entry route from its website at and its own Registration Center in Second Life, enabling students to get up to speed quickly in the virtual environment and and providing support in choosing the best study plan. Designed to be learning theaters under the heading of King’s Visualization Lab, this project is still growing within Second Life.ĭavid’s company now has 250 students from countries such as Yemen, France, Brazil, KSA (Kingdom of Saudi Arabia), China, India, Japan and Poland, registered to learn English in the immersive environment of Languagelab. The theaters reflect different time periods and different locations including Britain, Germany, Italy and Greece. Among other projects, he worked on a visualization project for King’s College to recreate historic European theaters in Second Life. His doctoral research was focused on looking at avatars as a theatrical paradigm, considering how much you as an individual are an audience for what your avatar is doing, and how much your avatar is a reflection of who you are. At the time he was a graduate student at the Center for Computing in Humanities at King’s College in Great Britain. Hadrian Yorke rezzed on Jand later Edgware Marker (real life name David Kaskel) first rezzed in Second Life on April 23, 2004, buying his first land in Second Life. This is the second installment of “Stories from Second Life,” an occasional series of profiles of the people behind Second Life innovations, and the tangible benefits that these individuals and their businesses have brought to both the virtual and the real worlds.
