ENCYCLOPEDIA OF ALTERNATIVE ENERGY AND SUSTAINABLE LIVING. Students in Ghana launch mini-satellite. KOFORIDUA, Ghana (AP) — Their project might not sound like much: The college students on Wednesday launched a tiny model of a satellite the size of a soda can on a big yellow balloon. It went aloft to a height of 165 meters (yards) and then came back down attached to a parachute. Yet in this developing West African country, ambitious organizers, —who recently launched the Ghana Space Science and Technology Center — see the test as a sign of bigger things to come.

"We hope that this practical demonstration of what can be done by students like them will generate more enthusiasm, fire up their imagination to come up with more creative things, and show that it's possible that they'll one day be able to launch their own real satellite into orbit," said Prosper Kofi Ashilevi, director of the space center that marked its one-year anniversary earlier this month. The effort has drawn some skepticism, acknowledged Samuel H. Donkor, the president of All Nations University. Lilypad floating city concept. The Lilypad floating city concept is designed to house climate change refugees Image Gallery (10 images) With global sea levels predicted to rise significantly over the next century due to climate change, a lot of people living in low lying areas are expected to be displaced from their homes.

Lilypad floating city concept

Architect Vincent Callebaut has come up with a possible relocation destination for these climate change refugees in the form of the “Lilypad” concept – a completely self-sufficient floating city that would accommodate up to 50,000. View all With a shape inspired by the highly ribbed leaf of Victoria water lilies, the double skin of the floating “ecopolis” would be made of polyester fibers covered by a layer of titanium dioxide (TiO2), which would react with ultraviolet rays and absorb atmospheric pollution via a photocatalytic effect in the same way as the air-purifying concrete and paving stones we looked at last year.

If my grandchildren ever ask me where I was when I realised the internet was over – they won't, of course, because they'll be too busy playing with the teleportation console – I'll be able to be quite specific: I was in a Mexican restaurant opposite a cemetery in Austin, Texas, halfway through eating a taco.

SXSW 2011: The internet is over

It was the end of day two of South by Southwest Interactive, the world's highest-profile gathering of geeks and the venture capitalists who love them, and I'd been pursuing a policy of asking those I met, perhaps a little too aggressively, what it was exactly that they did. What is "user experience", really? What the hell is "the gamification of healthcare"?

Or "geofencing"? Or "design thinking"? The content strategist across the table took a sip of his orange-coloured cocktail. This, for outsiders, is the fundamental obstacle to understanding where technology culture is heading: increasingly, it's about everything. Web 3.0 The game layer The dictator's dilemma. - Energy Saving Gadgets - Do They Work? - Energy Matters Forum. I have recently been looking for ways to cut down on my energy usage, both domestic and commercial, and in this process I have come across several gadgets that make great claims.

Some of these "gadgets" are well known and have a great deal of data and experience to prove their efficacy. Double glazing might be placed in this category. Some of these gadgets have a rational scientific reason to suggest that they are likely to work. Power factor correctors and VFD's for electric motors might be included here. Ecogadgets - energy saving and climate change tips. Energy Saving Devices. Do You Use Energy Saving Gadgets At Home? One of the key points Professor Tim Flannery made to us last week during our interview is that one of the simplest things you can do to both save energy and money is switching off gadgets at the powerpoint.

Do You Use Energy Saving Gadgets At Home?

But in true geek style, there are gadgets that actually do that for you – do you use them? The most striking example that comes to mind is Belkin’s lineup of Conserve power products. They have power boards designed to either let you remotely kill power to the majority of devices on the board, or alternatively have multiple ports follow a master connection, so that when that master device is switched off, power is cut to all other devices. Both are incredible intelligent and simple ideas that make saving energy so much easier. SpamLoco. Sustainable Innovations in Transportation.

Sustainability in Transport should address the issue of depletion of resources such as : energy, human and ecological habitats, atmospheric carbon loading capacity, and individuals’ available time.The need to plan for sustainable transport is evident as Global warming poses significant challenges for cities.

Sustainable Innovations in Transportation

According to the World Resources Institute (2005),the transportation sector accounts for 24.1% of CO2 emissions worldwide, yet its importance in local commuting, linking the global system of cities, and stimulating economic interactions is crucial. Concrete 'solutions' acceptable at an international level have been slow to emerge. Each country is constrained by its individual setting and hence faces unique hurdles in moving towards sustainability.
