Simple biomass briquettes you can make as a survival fuel source. Read full article: http://www.thediyworld.com/blog/?p=1469
With a simple caulk gun, some pvc tubing and a bit of hardware you can make a biomass briquette press. I show you how in a previous video. The link to that article can be found on the page above.
With access to a source of paper you can make your own survival heating and cooking fuel with ease. All you need is a bunch of shredded paper. If you have a paper shredder then you can shred paper yourself to use for biomass briquettes. You can also make a paper shredder if needed. Or you can shred paper by hand in an emergency.
For people living in the cities where wood as a fuel source is scarce this is a great survival skill to have. After the recent hurricanes on the East Coast many people were left without power for weeks or even months. People had not light, heat or access to clean drinking water.
Knowing how to make biomass briquettes can save your life and make a grid down situation more bearable.
If you live in the city it may be a good idea to have homemade biomass briquettes on hand already just in case of emergency.
You can use your biomass briquettes in a charcoal grill (outdoors only), in a wood stove or even an empty paint can in an emergency.
In a later article I will show you how to use a mix of paper and natural materials such as leaves to make biomass briquettes.
