Fuels from Sunlight, Water and Carbon Dioxide?


Problems with energy as we practice it today

gas prices

Fukushima accident

coral bleaching

hydrolic fracking

peak oil

BP Gulf Coast oil spill

Millions barrels per day

Canadian tar sands

Year


1 yr energy consumption

=

1 hr


150 million km


Storing Energy

gasoline

batteries

8 times the volume

16 times the weight


Chemical energy (liquid fuel) is high density


chemistry

heat

sun


Just a pinch of chemistry


The magic ingredient

cerium dioxide

hot

warm

CeO2

exhales oxygen

inhales oxygen


H2

Hot

Warm

O2

H2O

O

Ce

inhalation

releases fuel

exhalation


Solar energy is abundant

Chemical fuels store energy well

Solar heat uses all wavelengths of light

Designer materials use heat to make fuels
