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.

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

By - July 15, 2015 5 Pictures

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.

Silk-derived material could boost battery performance

By - March 12, 2015 1 Picture
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.
