8.5 Comparing Combustion with Fuel Cell Technology ProcessReactantsProductsComments Traditional Combustion Fuel: gasoline, hydrocarbons, ethanol, wood, ect. Oxidant: O 2 (from air) H 2 O, heat, light, sound; CO 2 and CO (greenhouse gases) Rapid process, flame present, lower efficiency, best process for producing heat Fuel Cell Technology Fuel: H 2 Oxidant: O 2 (from air) H 2 O, electricity, some heat Slower process, no flame, quiet and more efficient, best for generating electricity

8.6 Fuel Cell Autos Slim solid oxide fuel cell

8.7 Hydrogen (and oxygen) gas produced by the electrolysis of water. If the “Hydrogen Economy” becomes reality, where will we get the H 2 ? But this process requires energy.

The Hydrogen Economy: New Potential Sources of Hydrogen 8.8 Certain algae produce H 2 Via photosynthesis-very promising technology. A computer simulation of hydrogen molecules (red) absorbed onto both the interior and exterior of a collection of carbon nanotubes (blue). Realistic future?

Photovoltaic Cells 8.9 Energy of the future? An awesome source of energy. Our society has been using photovoltaic cells (solar cells) at a minimum level, but will we all begin picking up on this natural form of energy as a way to conserve our natural coal and petroleum supply? Thin wafers of ultra pure Si used for voltaic cells.

8.10 Other countries making use of solar energy Solar Park Gut Erlasee in Bavaria. At peak capacity, it can generate 12 MW. Harnessing the energy of the sun for pumping water It’s time to make important decisions and advances in alternative energy technology and new sources of renewable energy.
