An Australian inventor believes he can turn human waste into an energy source.
The concept of using biofuels -- any fuel that derives from biomass -- has gained ground in recent years. Biofuels are appealing since they are a renewable energy source and their combustion doesn't result in a net increase of carbon dioxide in the Earth's atmosphere (their carbon was already extracted from the atmosphere by growing plants). Currently around 15% of the world's energy consumption comes from bioenergy, mostly in developing countries where fuelwood, animal waste, and charcoal is burned for heating and cooking purposes.
Whether or not Mr. d'Oliveira process is commercially viable is still to be determined -- his plan would require significant changes in how waste is handled. For now Mr. d'Oliveira aims to raise funds to develop a pilot plant to test his concepts.
