Researchers have created printable solid-state batteries that can be printed in any conceivable shape and can be seamlessly embedded into a variety of surfaces. To demonstrate the technology, the scientists printed a working heart-shaped battery onto a cup, another onto a paper eyeglass and even one in the form of the letters "PRISS", all of which were capable of powering LEDs.
The scientists that revealed the "world's first solar battery" last year are now, following some modifications, reporting its first significant performance milestone. The device essentially fits a battery and solar cell into the one package, and has now been tested against traditional lithium-iodine batteries, over which the researchers are claiming energy savings of 20 percent.
Many of the more than 7,000 islands in the Philippines lack access to electricity, so after the sun goes down light usually comes by way of kerosene lamps. While cheap, these fire hazards are bad for the environment and human health. This, combined with the cost of keeping them burning has given one startup the impetus to build a better solution. The SALt (Sustainable Alternative Lighting) lamp burns for eight hours at a time running on only a glass of water and two teaspoons of salt.
Although battery life has improved markedly in recent times, most laptop users will still find themselves looking for a top up from the nearest wall outlet more often than they would like. MOS is providing a more flexible option for travelers with its Reach Go that is the first power bank capable of charging a compatible laptop at the same rate as a wall outlet.
The Solar Impulse team has announced that the completion of its
round-the-world solar flight will now be postponed until next April. The
batteries of the Solar Impulse 2 solar-powered aircraft sustained
damage as the aircraft ascended to an optimal energy-management
altitude of 28,000 ft (8,534 m) on the first day of its
ambitious Japan-to-Hawaii flight. It
is believed that a high rate of climb coupled with over-insulation of
the gondolas resulted in irreversible overheating damage to the aircraft's
Researchers at MIT have developed a new type of flexible, nanowire-based
supercapacitor with performance vastly exceeding its graphene
counterpart. It could find use as the ideal energy source for the next
generation of fitness trackers and other wearable devices.
If you want a smartwatch with week-long battery life, then you're better off with something like Pebble than a color touchscreen watch – they typically only last a day or two. But South Korea's LG Chem, the country's largest chemical company and part of the same corporate LG umbrella that also makes smartphones like the LG G4 and the LG G Watch Urbane smartwatch, reportedly has taken a step towards addressing the issue with a new hexagonal smartwatch battery.
A foldable, inexpensive paper battery that can generate a small amount of electricity brings a new sense of power to origami, the Japanese art of paper folding. An engineer at Binghamton University in New York has developed a battery that creates power through the process of microbial respiration in a drop of dirty water on paper.
In a very crowded marketplace, what can a newcomer to the Bluetooth speaker arena do to stand out from the crowd? Well, in the case of Mr. Everything, it's pack as much functionality and usefulness into a portable audio throwing box as possible. The water-resistant speaker comes with integrated emergency lighting, a wireless charging pad and enough stored juice to charge up a MacBook's battery twice or, as mentioned above, jump start a car. It's even got built-in storage. Not the flash memory kind, but somewhere to stow away essentials like protein bars or first aid supplies.
