Pure Driving: The Revolutionary Compressed Air Vehicle
If you can, imagine a vehicle that runs on air, achieves over 100 gas-equivalent mpg and over 90 mph, has zero to low C02 emissions, seats six, has plenty of space for luggage, cuts no safety corners, and costs no more than an average economy to mid-size vehicle.
This is the expected performance of the revolutionary compressed air vehicle that Zero Pollution Motors (ZPM) is introducing to North America. The vehicle is powered by the Compressed Air Engine (CAE) developed by Motor Development International (MDI), a 15-year old company based in Nice, France, and headed by inventor and Formula One race car engineer, Guy Negre. ZPM is the exclusive representative for MDI in the United States.

Download Link for Celestia The Open Source Software
.. The free space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X.
Unlike most planetarium software, Celestia doesn’t confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A ‘point-and-goto’ interface makes it simple to navigate through the universe to the object you want to visit.
Celestia is expandable. Celestia comes with a large catalog of stars, galaxies, planets, moons, asteroids, comets, and spacecraft. If that’s not enough, you can download dozens of easy to install add-ons with more objects.

Reach for the Robo-Raid: Bionic Hornet brings nanotech to war
I’m in two minds about this story - impressed, because nanotechnology is cool and tiny robots are even cooler, but more than a little disturbed at the idea of killer robots flying around and zapping people in the neck. Reuters is reporting that Israel are developing a bionic hornet that could chase, photograph and eventually kill enemy combatants or terrorists. Able to navigate tightly confined areas and so small as to be difficult to target by traditional weaponry, the concept is expected to reach prototype stage within three years.
It’s uncertain as yet whether the robots would be remotely controlled or have some sort of AI, though a combination of both is perhaps most likely; general targeting by remote, while short-range sensors automatically manage obstacle avoidance, tracking and flight.
Return of the Hindenburg
Always on the verge of a seeming comeback, airships are back in the spotlight, touting new technologies. The Defense Advanced Research Project Agency recently announced funding for an innovative, ballast-free airship technology created by Aeros Aeronautical Systems, based outside Los Angeles. The Aeroscraft ML866’s potentially revolutionary Control of Static Heaviness system compresses and decompresses helium in the 210-ft.-long envelope, changing this proposed sky yacht’s buoyancy during takeoff and landings, Aeros says.
It hopes to end the program with a test flight demonstrating the system. Other companies are planning their own first flights within the next few years. Each has a design that it promises will launch a new era of lighter-than-air transportation.
The fly’s a spy
A new type of flying machine is watching you Onera JUST below a half-opened garage door a tiny device can be seen at the feet of someone lurking in the shadows. It looks like a blue dragonfly. Then its miniature wings begin to flap as it slips under the door and darts along the street. After rising through the air it stops to hover outside the window of a building several storeys high. There is an opening on the roof, and it slips inside. As it flits from room to room its video-camera “eye” transmits pictures to a screen on a remote-control unit strapped to the wrist of its clandestine operator. This is not a scene from a James Bond film, in which 007 tests a new device from “Q”, but an animated video produced by Onera, France’s national aerospace centre, to explain REMANTA, a project to develop the technologies needed for miniature robotic aircraft. More bug-like flying devices are being developed in other research laboratories around the world. A few are already small enough to be carried in a briefcase; others are the size of a jet fighter and need a runway for take-off.
Having evolved from military use, drones, or unmanned aerial vehicles (UAVs), are taking to the air in increasing numbers for public-service and civilian roles. They are being operated by groups as diverse as police, surveyors and archaeologists. A UAV helped firemen track the blaze that recently ravaged southern California. The most immediate advantage of a UAV is cost: operating even a small helicopter can cost $1,000 an hour or more, but the bill for a drone is a fraction of that. However, the growing use of UAVs is causing a number of concerns.
The first is safety. Last month America’s National Transportation Safety Board (NTSB) completed its first-ever investigation into an unmanned-aircraft accident. Pilot error was blamed for the crash in Arizona in April 2006 of a 4,500kg (10,000lb) Predator B, a type of UAV used by American forces in Iraq and Afghanistan. It was being operated by Customs and Border Protection when its engine was accidentally turned off by the team piloting it from a control room at an army base. No one was hurt, but the NTSB issued 22 recommendations to address what Mark Rosenker, its chairman, described as “a wide range of safety issues involving the civilian use of unmanned aircraft.”
Bacteria and nanofilters — the future of clean water technology
Bacteria often get bad press, with those found in water often linked to illness and disease. But researchers at The University of Nottingham are using these tiny organisms alongside the very latest membrane filtration techniques to improve and refine water cleaning technology.
These one-celled organisms eat the contaminants present in water — whether it is being treated prior to industrial use or even for drinking — in a process called bioremediation.
The water is then filtered through porous membranes, which function like a sieve. However, the holes in these sieves are microscopic, and some are so small they can only be seen at the nanoscale. Pore size in these filters can range from ten microns — ten thousandths of a millimetre — to one nanometre — a millionth of a millimetre.

Bionic Bugs The eye in the sky
In July, however, a Harvard University team got a truly fly-like robot airborne, its synthetic wings buzzing at 120 beats per second.
“It showed that we can manufacture the articulated, high-speed structures that you need to re-create the complex wing motions that insects produce,” said team leader Robert Wood.
