Turning brewery wastewater into battery power

Engineers have developed an innovative bio-manufacturing process that uses a biological organism cultivated in brewery wastewater to create the carbon-based materials needed to make energy storage cells.

A solid future for batteries at IDTechEx's Energy Storage Innovations

At IDTechEx we believe that the future of the energy, mobility, electronics, and communications industry will be strongly shaped by the development of one key enabling technology, that is, energy storage. At the historical tipping point of structural change in these sectors there has never been a better time for a dedicated forum on energy storage as key enabling technology.

Common soil bacteria creates nano sized conductive wires

Scientists have genetically modified a common soil bacteria to create electrical wires that not only conduct electricity, but are thousands of times thinner than a human hair.

New autonomous unmanned surface vessels

To its manufacturer MOST (Autonomous Vessels) Ltd in the UK, USV means controlled by satellite from anywhere on the planet. AutoNaut is the answer to the age-old challenge of affordable oceanic data gathering for science, commerce and military purposes. It creates new opportunities to meet unique mission requirements in a changing world.

Tough new hydrogel hybrid doesn't dry out

Engineers have found a way to prevent hydrogels from dehydrating, with a technique that could lead to longer-lasting contact lenses, stretchy microfluidic devices, flexible bioelectronics, and even artificial skin.

Next generation display for diving helmets

This unique system enables divers to have real-time visual display of everything from sector sonar (real-time topside view of the diver's location and dive site), text messages, diagrams, photographs and even augmented reality videos.

Bionic leaf turns sunlight into liquid fuel

The days of drilling into the ground in the search for fuel may be numbered, because if Daniel Nocera has his way, it'll just be a matter of looking for sunny skies.

PolyPlus Battery Company

Polyplus is a US company that develops solid-state and semi-solid state electrolytes for lithium-air, lithium-sulphur and advanced lithium-ion batteries. After 20 years of R&D, they are now ready to enter both military and consumer electronics applications.

A flexible camera: a radically different approach to imaging

A team of engineers has developed a novel sheet camera that can be wrapped around everyday objects to capture images that cannot be taken with one or more conventional cameras.

3D printed aircraft to aircraft to navigate through ice

A tiny, pilotless, 3D printed aircraft has launched from the Royal Navy's ice patrol ship HMS Protector for the first time to assist with navigating through the Antarctic.

Scale up on ocean wave energy harvesting

The Mechanical Motion Rectifier, a novel power takeoff that uses the up and down and back and forth oscillation of wave energy and turns it into a unidirectional rotation to drive the generator.

First 3-D-printed component flies on U.S. Navy's Trident II D5 missile

The U.S. Navy's Fleet Ballistic Missile program flew into the future last week with its first 3-D-printed missile component.

New UAV can launch from underwater for aerial missions

Researchers have developed an innovative unmanned aerial vehicle that can stay on station beneath the water, then launch into the air to perform a variety of missions.

MIT develops nontoxic way of generating portable power

Researchers at MIT have come up with an alternative system for generating electricity, which harnesses heat and uses no metals or toxic materials.

SheerWind selected by cleantech accelerator

A cost-effective, high-performance alternative to conventional wind technology, by capturing, concentrating, accelerating, and harvesting wind power in a funnel system.
