Charcoal and wood
Biofuels in the developing world for Cooking
- Tanzania - less than 60% of the rural population is within range of the electric grid. There's no natural gas distribution network anywhere.
- You can cook by burning wood (16-20 MJ / kg) - bringing wood to market
- But you can "cook" wood anaerobically (burn *some* wood to heat-while-not-burning other wood) which dries it out and results in a product which burns hotter, and has a much higher energy / weight ratio called Charcoal (30 MJ / kg)
- Which fuel, wood or charcoal, do you think has the larger carbon footprint?
- Cooking indoors (with wood or charcoal) generates soot, and eventually lung irritation / health issues.
- Natural gas or propane burns much cleaner if (! $homepage){ $stylesheet="/~paulmr/class/comments.css"; if (file_exists("/home/httpd/html/cment/comments.h")){ include "/home/httpd/html/cment/comments.h"; } } ?>
