The energy-recycling foot enhances the power of ankle push-off (Image: Steve Collins)

Most of us take it for granted, but walking isn't as simple as it looks. With the natural human gait the ankle exerts force to push off the ground. A typical prosthesis doesn’t reproduce the force exerted by a living ankle, resulting in amputees spending much more energy in comparison to walking naturally. A new prototype artificial foot recycles energy that is otherwise wasted in between steps to significantly cut the energy spent per step, making it easier for amputees to walk.  Read More

The spokeless bicycle was the brainchild of nine Yale seniors from an engineering class

Usually, when you put nine university seniors together from a mechanical engineering class in a room for a whole semester with no strict agenda, the last thing you expect to get is a useful product. But this team broke the mold and created a “human-powered spokeless bicycle”. Admittedly, only the back wheel is spokeless, but the Yale students had two very good reasons for that – time and money.  Read More

The Noteput makes learning music notation more fun

When it comes to teaching children music, getting the little dears to bash away on a piano or strum away on a guitar usually isn’t too hard. Teaching classical music notation, however, is a different prospect entirely. The Noteput table concept from designers Jonas Heuer and Jürgen Graef attempts to make learning music theory fun, and also more effective, by combining the senses of hearing, sight and touch.  Read More

The Sway wind turbines bob in the water like partially filled bottles

The world’s biggest wind turbine will be constructed in Norway. The prototype turbine will stand 162 meters (533 feet) tall and feature a rotor diameter of 145 meters (475 feet). It is expected to be capable of generating 10-megawatts – enough to power 2,000 homes. The turbine will be tested on land in Øygarden in Hordaland County, Norway, for two years but is intended for offshore placement, where the winds are stronger and more consistent, and the concerns of ruined views and vibrations are removed.  Read More

The DeltaWing, proposed to replace the current IndyCar chassis

Two of four submissions have now been unveiled by the companies wishing to produce the next generation of IndyCar open-wheel racers, and the most recent one is one of the most fascinating looking racecars we've ever seen. The DeltaWing is a radical departure from traditional open-wheeler design - in fact, the only thing you could really compare it to is the bizarre lovechild of a drag racer and a Batmobile. With its comically narrow rocketship front end, broad rear end and narrow tyres, the DeltaWing aims to outperform the current crop of IndyCars for significantly less money, while delivering extraordinary efficiency gains and leaving a clear airstream for following cars, in order to promote close racing and overtaking. But is the public ready for a car that looks... so little like a car?  Read More

The composite material releasing electrical energy to power a small light (Photo courtesy ...

The problem is clear. Hybrid cars and EVs rely on batteries for power, but batteries are bulky and heavy, causing the car to use up more energy. But what if a car's bodywork was made of a strong, lightweight material that could store and discharge electrical energy just as a conventional battery does? In pursuing this goal, researchers at the Imperial College London are developing a key building block for the hybrid car of the future, and the implications go way beyond automobiles - think wafer thin mobile phones and laptops that don't need a separate battery because they draw power from their casing.  Read More

iSOCO electronic invoicing exchange could save 30 percent of processing costs

It's a universal problem - one you may be surprised to hear we still face in today's technological age: you send me an invoice with your software, my software can't read it so I waste time and money interpreting it. iSOCO promises to change all that with its new prototype i20nt. This system aspires to become the first to exchange electronic invoices between companies transparently and regardless of their originating format and system, saving up to 30% of the total invoice processing costs.  Read More

The FABLABHOUSE entry from Instituto de Arquitectura Avanzada de Cataluna is shaped for op...

Madrid will host the first European version of the Solar Decathlon competition this summer which sees teams from universities throughout the world designing, building and displaying efficient and sustainable solar homes. The overall competition winner being decided after the completion of ten trials aimed at gauging each entry's energy efficiency and sustainability credentials.  Read More

The Russian T-50 PAK-FA fighter jet prototype taking its maiden flight

Russia has reportedly successfully test-flown its first fifth generation fighter jet prototype. Formally known as the Prospective Aircraft Complex of Frontline Aviation (PAK-FA), the craft made its 47 minute maiden voyage on 29th January. Manufactured by the Russian state owned Sukhoi Aircraft Corporation, the development of this tactical frontline stealth fighter jet is being seen as a significant milestone in the efforts of the country to modernize its post Soviet–era military technology.  Read More

Applying an electric field will make the new device adhere to a surface, reversing the fie...

Researchers at Cornell University have created a palm-sized device that uses water tension as a switchable adhesive bond and can support many times its own weight. The device could usher in a whole new generation of superheroes by allowing shoes or gloves that stick and unstick to walls on command, or see the creation of Post-It notes that can bear loads.  Read More
