Via Gizmodo, comes this interesting tip for survival, If we need to fire somewhere inhospitable.(Vandals please abstain)

It’s already rare to find a good geek wandering somewhere away from civilization, without having the minimum basic services: electricity and wifi. But occasionally, either by prevailing physiological needs  -notice draw attention of the opposite sex-, or simply friendship is possible to mount an adventure away from all that is called modern life in the maw of nature

Recall that there are many places in our country, from east coast to the wild where they can remain stranded without communication and without pobilidad obtain fire either to cook or just to warm. What can we do?

For those who do not carry a boy scout kit with us all the time, I suggest you to watch Survivorman . But in this case, we can survive to this particular need armed with :

• Cell battery or a 9v.
• A metallic wool scourer

… We can generate enough heat to survive until help. It is simply a matter of making a bridge between the poles of the battery and a piece of wool, which generates the spark that will allow a suitable fuel (straw, wood, gasoline) to generate what we want.

It is nice to think that, without carrying around a chest behind him, we have in our pocket something useful in emergencies. Please do not do this at home, at least, without the supervision of a member of BCB near you.
