Image Gallery (2 images)
Plans announced by Kawasaki Heavy Industries could see a new record set for high-speed train travel in Japan. The design for the rail vehicle dubbed the “Environmentally Friendly Super Express Train” (efSET) is expected to be completed by the end of 2009 and its promised operating speed has been pitched around the 217mph (350 kmh) mark, quicker than the fastest trains currently operating on the country's high-speed Shinkansen network which clock around 188mph (300kmh).

Honda's all-new 2009 CRF450R Motocrosser gets fuel injection
Image Gallery (9 images)
Honda's CRF450R motocross bike has been hugely successful since its launch in 2002 - and although the bike is already recognized as the class leader, it's receiving a kitchen-sink included upgrade for 2009. Lighter, quicker, more powerful and with even tighter mass centralization for quick handling, the 2009 CRF450R also sports a Honda first - battery-free, programmable fuel injection that raises output power and control while dramatically reducing fuel consumption. Out of the box, Honda says it's two seconds faster around a supercross track than this year's bike. Read More

Virgin Galactic has achieved another milestone in its push to become the world’s first private commercial spaceline with the unveiling of the WhiteKnightTwo (WK2) carrier aircraft. Built at the Scaled Composites facility in Mojave, California, the twin fuselage WK2 is a formidable engineering feat. It is the world’s largest all carbon composite aircraft and the main wing, which spans 140 ft, is the longest single carbon composite aviation component ever built. Christened “EVE” in honor of Sir Richard Branson's mother, the aircraft can can fly across the US non-stop and reach altitudes of 50,000 ft - the height from which SpaceShipTwo (SS2) will be air launched.

World's smallest camera carrying Micro Aerial Vehicle takes flight
Image Gallery (3 images)
July 28, 2008 How often have you thought, “I’d like to be a fly on the wall in that room”. Well, a team at the Delft University of Technology in the Netherlands is hard at work trying to make that desire a reality by developing a Micro Air Vehicle (MAV), which they claim is the smallest flying, camera carrying ornithopter in the world. The DelFly Micro weighs just 3 grams and measures 10 cm from wing tip to wing tip. It has a range of 50 meters and is powered by a 30 mAh lithium polymer battery, which provides enough power for three minutes of fight time. To keep the weight of the unit down the wings are made from Mylar foil, while the body and frame is made up from carbon and balsawood. Read More
The plasma-powered flying saucer

University of Florida mechanical and aerospace engineering associate professor Subrata Roy has submitted a patent for a circular, spinning craft that can hover and take off vertically. The wingless electromagnetic air vehicle, or WEAV, is just six inches across, but has the potential to be scaled up to a much larger size. The WEAV is covered with electrodes that ionise the surrounding air into plasma, which functions as the conducting fluid. Passing a current through the plasma creates lift and momentum. Read More
Odysseus: Aurora's radical, unlimited endurance, solar powered aircraft
Image Gallery (3 images)
May 2, 2008 Aurora Flight Sciences has revealed the design of the aircraft it hopes will achieve the ambitious goals set out in DARPA's ambitious Vulture program: sustained uninterrupted flight for over five years at altitudes of 60,000-90,000 feet. Known as Odysseus, the solar-powered concept aircraft is as radical as the mission it is designed to accomplish, combining three self-sufficient “constituent aircraft” in a unique Z wing configuration that spans almost 500 feet (150 meters). The modular design provides several advantages - the shape of the aircraft can be adjusted to maximize the solar collection properties during the day and spread flat for aerodynamic efficiency at night-time, and because each of the constituent vehicles is capable of autonomously docking at altitude, the design also facilitates the replacement of one section of the plane whilst it is still aloft.

April 8, 2008 A spectacular new type of aircraft is one step closer to take-off with the announcement that the United States Federal Aviation Administration (FAA) has accepted the type certification application for the Aeroscraft model Aeros ML866. Read More
Bumpy whale fins set to spark a revolution in aerodynamics
Image Gallery (4 images)
March 21, 2008 It seems despite man's endless ingenuity and the incredible modeling power available to inventors through CAD systems, we keep looking to nature to find ever more effective ways of doing things. Millions of years of evolution's trial and error approach have resulted in some incredibly effective designs that are ready to be incorporated into human constructions if we can only identify, understand and replicate them. The random-looking bumps on the humpback whale's flippers have just inspired a breakthrough in aerodynamic design that seems likely to dramatically increase the efficiency and performance of wind turbines, fans, flippers and even wings and airfoils. WhalePower's tubercle technology seems like nothing less than a revolution in fluid dynamics. Read More
Boeing KC-767 refuels an F-15E in night conditions

January 31, 2008 The Boeing KC-767 tanker aircraft has successfully transferred fuel to an F-15E at night – a world first manoeuvre for that model. Transferring fuel through a boom, via the remote vision system, and during night-time conditions, will significantly reduce risk for future tanker customers like the U.S. Air Force. Read More
Aptera officially launches futuristic, super-efficient three wheeler

The pressing need for a shift to efficient, low-emission vehicles has seen an array of eco-friendly models showcased by major auto manufacturers in recent times, but this new era of personal transportation also provides a starting point for smaller players with fresh ideas to enter the marketplace. Fitting squarely into this category is Aptera Motors, a Californian based company that has just announced the official launch of the Typ-1 - a radical new three-wheel, two-seat design available in all-electric or plug-in-hybrid versions that bundles bleeding-edge aerodynamics, incredible fuel efficiency and a strong focus on safety in a package that will cost less than USD$30,000. Gizmag spoke to Aptera Co-Founder & CEO Steve Fambro on the technology behind these eye-catching vehicles and the future plans for the company as it moves rapidly into the commercialization phase.

Logan Renault eco² achieves emissions of 71g/km
Image Gallery (9 images)
The Logan Renault eco² Concept has achieved emissions of 71g/km while traveling a distance of 172.2km on just 4.69 litres of biodiesel at the 2007 Challenge Bibendum in Shanghai – an event created by Michelin in 1998 that promotes sustainable transport and the development of fuel-efficient, clean automotive technology. In NEDC combined cycle homologation tests for the eco² it achieved a result of 97g CO2/km and finished second out of 74 vehicles in a combined criteria test involving an acceleration test, a slalom test, noise emissions and a regularity run. To put the emissions results in perspective, a compact diesel achieves around 130g CO2/km and the exceptionally green smart fortwo diesel comes in at 88 grams of CO2 per kilometer. Read More
America’s only 180mph rolling-road wind tunnel
Image Gallery (4 images)
October 1, 2007 The Windshear rolling-road wind tunnel in North Carolina will be one of the fastest and most advanced facilities in the world, and the only in America capable of 180mph (around 300kph) testing. The US$40 million complex will be an excellent resource for Formula One, NASCAR and most other racing teams – but interestingly, street-legal supercars like the Bugatti Veyron at the forefront of high-speed aerodynamic design still have nowhere to test their 250+mph models.
