Physics has found its 'Holy Grail': self-sustaining plasma.
Folks aboard the International Space Station captured this image of the wildfires sweeping through Idaho on September 19, 2012.
We tend to think of people peeing on fires to put them out, but a survivalist needs to be resourceful. So: here's a way to use your own pee to start a fire.
DARPA's (Defense Advanced Research Projects Agency) sonic fire extinguisher is not at all what you'd expect. It is designed to fight small flames in contained areas like plane cockpits with sound.
We've seen our fair share of Rube Goldberg machines, and the reason we like them so much is for the hundreds of little gizmos and motions used to accomplish something pretty simple. This one isn't even new — the video was posted in 2009 — but it's going around again and won us over by being powered largely by fire.
Science may be able to explain many things about how our world works, but communicating such things in a way that can be understood by 11 year olds (or the rest of us) is not easy to do. Take a flame, for example: just what the heck is going on there? This video, winner of Alan Alda's Flame Challenge, explains it in an easy and fun way.
Now that the price of gold is so high, it's starting to bring out the wackos with their crazy schemes to create the precious metal from ordinary stuff. Still, it's hard to top Paul Moran's scheme, which had the man cooking his own poop combined with fertilizer and some other stuff on a heater in his house.
There're plenty of ways to warm up for a football game. Hanging out in the back of a pickup and drinking beer, for one. Or, hey, roll out a grill! Lance Greathouse? Well, lets just say what he likes to do includes all of that, as well as a powerful sound system, LCD displays and a fire-vomiting smokestack.
There may be a little of color enhancement going on here, and it may also be a long exposure that's been mirrored over one axis, but, otherwise, this is exactly what it looks like when you burn a fuel droplet in microgravity.
Regular gloves keep your hands warm, sure. But only Flame Gloves keep your hands warm by shooting fire out of them.
