"Building scientists have known for a long time that glass-walled structures are less energy efficient than the stone and concrete buildings that were put up forty of fifty years ago. But the market demand for glass combined with the relatively low cost of glass-wall construction means the building industry has been happy to oblige."

Throw-away Buildings Thermal Window Failure: How it Happens Virtually all glass condominium towers feature window wall systems (floor-to-ceiling walls of glass) enclosing the entire facade. Window walls yield spectacular views, but owners who buy a condo unit for the view may not realize that they're relying on a couple of panes of glass separated by less than an inch of insulated space to protect them from the elements. That insulated barrier will degrade over time, even as energy costs increase. On some buildings, five per cent of the thermal windows may have failed before they're even delivered to the construction site. Another 10 - 15 per cent will fail by the 20-year mark as they're exposed to the physics of heat expansion. By the 25 year-mark, a growing number will fail every year.

"An ambitious solar energy project on a massive scale is about to get underway in the Arizona desert. EnviroMission is undergoing land acquisition and site-specific engineering to build its first full-scale solar tower - and when we say full-scale, we mean it! The mammoth 800-plus meter (2625 ft) tall tower will instantly become one of the world's tallest buildings. Its 200-megawatt power generation capacity will reliably feed the grid with enough power for 150,000 US homes, and once it's built, it can be expected to more or less sit there producing clean, renewable power with virtually no maintenance until it's more than 80 years old."

A man has climbed up a BBC building using a pair of vacuum gloves he built himself, in a stunt for a new BBC One science show.

Earthship Biotecture creates buildings that... * Heat and cool themselves naturally via solar/thermal dynamics * Collect their own power from the sun and wind * Harvest their own water from rain and snow melt * Contain and treat their own sewage on site * Produce food in significant quantities * Utilize materials that are byproducts of modern society like cans, bottles and tires

To give everybody an opportunity to make his own "hands on" experience with the Nanoworld we provide all information to build up and use some of the standard equipment of this fascinating field of science, starting with the Nobel-Prize-Winner of 1986: the Scanning-Tunneling-Microscope (STM).

"A lonely island in the middle of the South Atlantic conceals Charles Darwin's best-kept secret. Two hundred years ago, Ascension Island was a barren volcanic edifice. Today, its peaks are covered by lush tropical "cloud forest". What happened in the interim is the amazing story of how the architect of evolution, Kew Gardens and the Royal Navy conspired to build a fully functioning, but totally artificial ecosystem."

From the documentary film "Nuclear Boy Scout", the true story of the boy who set out to build a nuclear reactor in his garden shed. The complete documentary is available on DVD from producer@eagletv.co.uk

"Many might be alarmed to learn of a homemade nuclear reactor being built next door. But what if this form of extreme DIY could help solve the world's energy crisis? "

Building a trebuchet from scratch and finding the best proportions, weights, angles etc by trial and error certainly works ..well, that's how the Grey Co's first machines were done... but if you could model the rock-throwing beasts mathematically then think of the work and possibly wasted effort you could save.

Besides giving away to charity, most rich people waste their money on boring, frivolous things such as yachts, diamonds, and mansions. Here's a rich English guy that knows how to have fun. I hope he does build a bigger one. I would like to see a flying double-decker bus.
