>Colorless

>Odorless

>Nontoxic

>Does not produce acid rain

>Does not deplete ozone

>When pure Hydrogen isused in a fuel cell the

products are electricity,

heat and water

Advantages Advantages !isadvantages !isadvantages

>Burns vs. Explodes

>1/10 the heat of gas fire

>22 x weaker than gas explosion

at the same explosion

>No smoke

Waste Water

Wastewater, also spelled waste water, is any water that has been adversely

affected in !ality by anthropogenic infl!ence" #t comprises li!id wastedischarged by domestic residences, commercial properties, ind!stry, and/or

agric!lt!re and can encompass a wide range of potential contaminants and

concentrations"

BiomassBiomass

$iomass, as a renewable energyso!rce, is biological material from

living, or recently living organisms

#nd!strial biomass can be grown

from n!mero!s types of plants,

incl!ding miscanth!s, switchgrass,hemp, corn, poplar, willow, sorgh!m,

s!garcane,and a variety of tree

species, ranging from e!calypt!s to

oil palm %palm oil&"

$iomass is carbon, hydrogen and

oxygen based"

*$ /lectron transport by artificial mediators

n this proposed mechanism electrons are transported by artificial mediators, sometimesreferred to as electron shuttles $his chemical materials offer the possibility for

microorganisms to generate reduced products that are more electrochemically active than

most fermentation products$
