Four time Solar Challenge winners unveil new car Nuna5

The team that won the World Solar Challenge for the last four years running has unveiled its latest solar racer. Like its predecessor, the Nuna5 from Delft University's Nuon Solar Team is covered with six square meters of solar panels but is 30kg lighter at a super low 160kg excluding driver.  Read More

Cargine's camless combustion engine concept

A petrol powered Internal Combustion Engine (ICE) is approx 25-30% energy efficient at the flywheel and around 15% energy efficient at the wheels. There are many losses within the engine itself including friction and waste heat from the combustion process, but Sweden's Cargine Engineering thinks that eliminating the parasitic losses of the camshaft by building a camless engine may help improve energy efficiency. Using pneumatically driven actuators to shoot the valve open the camless engine concept can provide fully variable valve lift and fully variable lift duration without a camshaft in sight.  Read More

The 'Muecke' (mosquito) single seater lightweight helicopter concept

The "Muecke" (mosquito) is a single seater lightweight sport helicopter concept that combines low weight and corresponding low flying costs in an easily transportable design which would make this flying machine the ultimate in personal aviation. The mini chopper is intended to be powered by a shaft driven turbine and features counter rotating blades. This means it does not require a tail rotor, instead utilizing movable paddles at the tip of the rotor blades which act like a kind of thrust vectoring of the turbine exhaust to help make course corrections in forward flight as well as in hover.  Read More

robot helicopter which can teach itself to fly by watching other helicopters in the air

Autonomous helicopters offer a highly maneuverable and versatile platform in scenarios like disaster relief operations, but programming these machines to perform complex aerobatics is a formidable challenge - unless of course they teach themselves. This example developed by Stanford computer scientists does just that, learning to fly by watching other RC helicopters in the air. Not only does this artificial intelligence system produce a spectacular flying exhibition, it's seen as an important demonstration of robotic learning through observation.  Read More

ADDZEV was developed using a standard Vauxhall Combo van

Automotive engineering facilities in the UK have joined forces to design a system which allows conventional delivery vans to be cheaply converted to run in a zero-emissions, all-electric mode for urban use. The ADDZEV (affordable add-on zero emissions vehicle) system was developed using a standard Vauxhall Combo van, retaining the existing conventional front-wheel-drive (FWD) system and an adding an electric drive in parallel for the rear wheels. The vehicle can operate with just front wheel drive powered by the internal combustion engine or can turn off the petrol engine and run with rear wheel drive under electric power only.  Read More

WORLD RECORD Water Rocket Car 0 - 343.5 kph in 2.5 sec

In 1974 Evel Knievel launched himself across the Snake River Canyon in Idaho aboard the rocket powered Sky-Cycle in what was to be the biggest stunt and biggest flop of his daredevil career. The Skycycle X-1 and X-2 were more rocket than they were motorcycle and both were powered by overheated water rockets. This incredibly powerful means of propulsion also saw the team at Swissrocketman achieve a blistering 214.7 mph in 2.5 seconds back in 1992 - a water-rocket record that has remained unbeaten ever since.  Read More

Raser Technologies has begun delivering 10 megawatts (MW) of clean, renewable electricity to Anaheim, California, from its first low-temperature, binary geothermal plant, the Hatch Geothermal Power Plant in Beaver County, Utah. Traditionally, the lead time on a geothermal plant is three to five years, but the USD$33-million Raser plant has been powered up just five months after ground-breaking. To help meet such rapid construction schedules, the plant uses off-the-shelf modular components, taken from the air conditioning industry, which are essentially running in reverse.  Read More

With the World Rally Championship (WRC) switching over to S2000-based cars next year, we thought it may be a good time to have a closer look at what has proved to be the fastest S2000 rally car so far, the Mellors Elliott Motorsport (MEM) build Proton Satria Neo Super 2000. In the hands of Irish driver Niall McShea, the Proton caused quite a stir on the first WRC event earlier this year, Rally Ireland, when it stormed into a podium position on day one, ahead of a full field of WRC machinery.  Read More

Last week we reported on the two-seater Hummel helicopter concept and mentioned that it looked very similar to the SoloTrek XFV (Exo-skeletal Flying Vehicle) backpack helicopter flown in the movie Agent Cody Banks. We haven't had a close look at this Exoskeleton Flying Vehicle but, although the design was first tested in 2003, it's still a unique form of transport that we hope to see more of in the future.  Read More

Citroen's C1 ev'ie, the UK's first all-electric family car, has gone on sale in the United...

The first all-electric family car went on sale in the United Kingdom over the weekend. Electric Car Corporation Plc has launched a lithium ion battery-powered, all-electric version of the Citroen C1, called the C1 ev'ie. Unlike the previous largest selling electric vehicle in Britain – the Indian-built Reva G-Wiz, which was legally classed as a quadricycle – the C1 ev’ie is a proper car, albeit a mini car.  Read More
