1 Fuels from Sunlight, Water and Carbon Dioxide?

2 Canadian tar sands Problems with energy as we practice it today peak oil Millions barrels per day Year hydrolic fracking coral bleaching Fukushima accident BP Gulf Coast oil spill gas prices

3 1 hr = 1 yr energy consumption

4 150 million km

5

6 Storing Energy 8 times the volume 16 times the weight gasoline batteries

7 Chemical energy (liquid fuel) is high density

8 chemistry heat sun

9 Just a pinch of chemistry

10 The magic ingredient cerium dioxide hot warm exhales oxygen inhales oxygen CeO 2

11 O2O2 H2H2 H2OH2O Hot Warm exhalation inhalation releases fuel Ce O

12 Solar energy is abundant Chemical fuels store energy well Solar heat uses all wavelengths of light Designer materials use heat to make fuels
