Hurricanes, earthquakes, elected officials—there are plenty of legitimate reasons to prepare for the end of civilization as we know it, and if the world’s supply of batteries ever runs out, you’ll be glad you had this emergency LED lamp tucked away in your doomsday shelter.
A team of Chinese scientists did an impossible-sounding thing. They created electricity simply by dragging a droplet of saltwater across a layer of graphene. No big fires, no greenhouse gases, no fuss. They created energy with just a miracle material and one of the most plentiful substances on Earth.
This map is the result of one very busy month of data collected by NASA's Aquarius instrument, offering the first ever global map of the ocean surface's saltiness. This information has potentially profound implications for our understanding of changing climates.
It looks like a Pennsylvanian has found a way to allow saltwater to burn when it's being exposed to the proper frequencies. Can you say new fuel source? No? How about "We don't know if this works or not." Yea, me too. [Wired]
