SALt lamp runs on a glass of water and two teaspoons of salt

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.Read More

Next leg of Solar Impulse round-the-world flight pushed back to April 2016

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 batteries. Read More

LG's hexagonal battery gives an extra charge to round smartwatches

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.

Mr. Everything wireless speaker can jump start a car

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.

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.Read More

Silk-derived material could boost battery performance

Next-generation lithium-ion batteries may hold more charge for a greater number of cycles thanks to a new material derived from natural silk. Scientists at the Beijing Institute of Technology found that not only does their regenerated silk fibroin material work for over 10,000 cycles but it also stores five times more lithium than graphite, which is the most common choice for the anode (negative electrode) in lithium-ion batteries.Read More
