There can be little doubt that people love their mobile devices. But, by leaving them high and dry at the most inconvenient of times, this love generally doesn't extend to the batteries that power said devices. New microbatteries developed by researchers at the University of Illinois at Urbana-Champaign (UIUC) that measure just a few millimeters in size, yet are powerful enough to power a mobile phone may be more likely to inspire a little love.  Read More

Dead seaweed on a beach in the Spanish city of Alicante

When it’s alive and in the ocean, seaweed serves as a habitat, spawning ground and food source for marine life. Once it gets washed ashore, however, it pretty much just rots. Typically, along beaches in tourist areas, that dead seaweed is simply gathered and taken to a landfill. Now, however, researchers from Spain’s University of Alicante have conceived of a new seaweed-removal system that has less environmental impact, and that allows the seaweed to be used as an energy source.  Read More

The Tarot is claimed to be the 'world's thinnest power bank'

Keeping mobile phones charged is rapidly becoming just as profitable as making the smartphones themselves. As such, we're seeing all kinds of power banks hitting the market. We saw the Fuel charger hit Kickstarter earlier this month, which claimed to be the world's smallest battery back-up, and now a company called Powerocks is entering the fray with Tarot, which it claims is "the world's thinnest power bank."  Read More

Splitterwerk Architects and engineering firm Arup have unveiled what is thought to be the world's first building to be powered partly by algae. Officially "unveiled" at the International Building Exhibition hosted in Hamburg, the design, dubbed the BIQ, has a "bio-adaptive" facade that is claimed to be a first for using algae within its glass louvers in order to generate energy, and provide shade, to a working building.  Read More

Using the hand crank of the SOSCharger to provide power to an iPhone

When there's a natural disaster or bad storm, power outages are almost guaranteed. This can be an annoyance during a minor storm, but during a more serious disaster, a lack of power can mean not being able to get in touch with friends, loved ones, and in the worst of situations, help. The SOSCharger is designed to combat this by allowing users to keep their phone charged with a simple hand crank.  Read More

Technology has advanced markedly since the dawn of the silicon age, but our portable gadgets and gizmos are still largely held back by the limitations of their power source. Scientists at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden report progress in this regard, with the development of a new longer-lasting lithium-sulfur battery that has the potential to outperform lithium-ion batteries, at a lower cost.  Read More

A sketch of the final design for the Amazing Jellybean

When the internet goes down, the first thing anyone should do is power cycle their modem and router – it seems like almost every internet problem can be fixed by simply turning everything on and off in the right order (as long as the problem is not on the ISP's end, of course). The process takes a good five minutes, between waiting and timing everything right. The Amazing Jellybean aims to make it simpler by allowing users to simply push one button, and have everything power cycled for them in the correct order.  Read More

A typical smartphone flash with its existing capacitor (silver cylinder), and the new poly...

While stand-alone compact cameras are increasingly at risk of being made obsolete by smartphone cameras, they do still have their advantages. One of those advantages is the fact that, in most cases, their flashes are considerably more powerful. Smartphones may soon be catching up in that area, however, thanks to a new small-but-mighty capacitor paired with a dedicated xenon flash.  Read More

NASA's research holds the promise of a home nuclear reactor (Image: NASA)

If Joseph Zawodny, a senior scientist at NASA’s Langley Research Center, is correct, the future of energy may lie in a nuclear reactor small enough and safe enough to be installed where the home water heater once sat. Using weak nuclear forces that turn nickel and hydrogen into a new source of atomic energy, the process offers a light, portable means of producing tremendous amounts of energy for the amount of fuel used. It could conceivably power homes, revolutionize transportation and even clean the environment.  Read More

Britain is better prepared for a solar superstorm than many countries, including the United States. The Royal Academy of Engineering has released a multi-disciplinary report on space weather’s impact on Britain, as part of the UK National Risk Assessment. The declassified portion of the assessment shows the level of UK preparedness in the face of severe solar storms, and outlines the dangers Earth faces from superstorms and how to avoid or mitigate damage.  Read More
