As an alternative to electromobility, fuel cells are gaining in importance. Their lifetime is limited as the catalysts corrode rapidly. Specially layered nanoparticles bypass these disadvantages.

The picture shows the structure of a catalyst molecule consisting of platinum-cobalt atoms.

The novel catalyst consists of a shell of platinum atoms. Inside, platinum and cobalt atoms are specially layered. This increases performance and makes the catalyst last longer.

In the spring of 2017, “Project Portal” named Toyota its “next step on the road to pollution-free freight and freight traffic”. The new truck with a hydrogen-powered fuel cell drive called Alpha (more…)

Short-haul with battery, long-haul with fuel cell? Mercedes obviously wants the best of both worlds.

Actually, the competition for “locally emission-free” mobility was already decided. Increasing ranges seemed to give the pure Stromern the victory over the hydrogen drive. But quite as great it looks with the ranges, especially in vans (more…)

A miniature submarine that can do without engine, fuel and electricity? This works in the first approaches, as an alternative drive concept by ETH Zurich proves. It relies on artificial shape memory muscles that derive their energy from temperature differences.

For the time being, electromobility is turning a transmission into a powertrain manager. But in the long term, Matthias Zink from Schaeffler expects a simplification of the drive components. Which should not mean an easy way for the development.

Bosch has allegedly developed the cleanest diesel in the world: With a greatly improved exhaust aftertreatment, the automotive supplier has succeeded in reducing the NOx emissions of a VW Reduce golf in real traffic to only 13 mg per kilometer. The cost of the components: about 100 euros.

Bosch has developed a technology that will radically reduce the NOx emissions of diesel cars , The development is even ready for production. Talks with car manufacturers are already (more…)

“Go for it!” Has been saying for decades – but few really do. The gas pedal is actually a gasoline or diesel pedal. This will have to change in the next few years, because the fossil fuels are finite. In the long term, electric vehicles could usher in a new era of automobiles. Considering the short term, natural gas propulsion could become popular.

Back to the bike is the motto in today’s city center logistics. Will the frenzied, stinking and wildly packed parcel vans that are clogging our cities soon die out? The Bremen-based company Rytle is working on it. In the future, quiet and manoeuvrable hydrogen-powered e-bikes will make the last mile green in the parcel delivery.

Will the big players compete in commercial space travel? The British company Reaction Engines has been working on a new propulsion system for the “Skylon” spacecraft for about 30 years, which is both a reusable space shuttle and super-fast hypersonic jet. Recently Boeing and Rolls-Royce joined as investors. That makes you sit up and take notice.

Skylon, the plane for space, is being built in England

Skylon is set to launch on Earth like an airplane and becomes supersonic jet in space.

Russia has apparently tested a flyable nuclear-powered rocket that will reach up to ten times the speed of sound. With that she would hardly be hit by a missile defense. The rocket was launched in flight by a MIG31. The Russian Ministry of Defense has published a corresponding video.
