How Can We Turn Sun Radiation into Automotion?by Ron Swenson, Sustainable Transportation FundThe Future of Automotive Energy: Fossil Fuels, Agro Fuels or Photovoltaic Cellshosted by SIKA & CHUStockholm November 6, 2007
We face enormous challenges • Global Warming • Peak Oil • Deeply corrupted governments (USA) • Industry Sell-Outs • Well meaning environmentalists • GreenWashers
We must develop enormous programs to meet these challenges. • The $21 Trillion already committed to carbon is destructive. • We need to overcome collective ignorance, and get a grip on the scale of the challenge.
The fires are burning! Fires in Congo & Angola
Larsen B Ice Shelf Collapse • Feb-Mar 2002 • In about 35 days • Larger than Rhode Island • Totally baffled scientists • 1 down, 4 to go
Peak Oil "Today I believe is the end of cheap energy. It's essential that we move away from fossil fuels as fast as possible. The boat is sinking and we have to do everything we can to plug the hole.” Lord Ron Oxburgh, former chair of Shell
The Pretenders IEA, EIA, Shell, BP, Saudi Aramco, Lynch, Adelman, Yergin, Lovins www.HubbertPeak.com/Pretenders
The Pretenders “The Commission does not embrace the view that world oil production has peaked.” The National Commission on Energy Policy www.HubbertPeak.com/Pretenders
Deeply corrupted governments (USA) • In cahoots with corrupt industry, responsible to no-one • requiring both internal and external pressure to make change possible • Best pressures are technological advancements and market effectiveness

GreenwashersWell-meaning environmentalistsAcademics who know but won’t tell
GreenWashers • Greenwashing," a pejorative term derived from the term "whitewashing," was coined by environmental activists to describe efforts by corporations to portray themselves as environmentally responsible in order to mask environmental wrongdoings. www.businessethics.ca/greenwashing/
Well meaning environmentalists • Too lazy or incompetent to do the math
F. Sherwood Rowland The Nobel Prize in Chemistry 1995 Rowland theorized that manmade organic gases combine with solar radiation, releasing atoms of chlorine and chlorine monoxide destroying ozone. Rowland's research, published in Nature, 1974, initiated a scientific investigation. The National Academy of Sciences concurred in 1976, and in 1978 CFC-based aerosols were banned.

Internal Combustion … • Take 26.5 Quads of oil • Turn 21.2 into smoke • Use 5.3 to run things … How incredibly wasteful!?
Two out-of-date ways to produce power • ExternalCombustion (Boiling water)James Watt (1776) … includingnuclear power, just a fancy boiler, inherently inefficient. • Internal Combustion (Burning oil)Rudolf Diesel (1893) … hybrid electrics are just variations, inherently inefficient, heavy, under-utilized.
There is no Silver Bullet. Why Silver in the first place? • The Lone Ranger chose silver to emphasize that silver, like life, was precious and should not be wasted. • Specific gravity of Pb = 11.35 • Specific gravity of Ag = 10.50 Ag Ag
There is no Ag Bullet. • Now I think I follow what you mean. Let’s find out why….
Burning biofuels perpetuates inefficiency • Internal combustion is the PROBLEM.
Roscoe Bartlett “It might seem possible to “fill the gap” in the short term. However, in the long term, this will be impossible. For one thing, it will hasten the exhaustion of other finite resources. That will make the inevitable transition to renewable sources more difficult and more painful.”

EROEI for Tar Sands Plus… • Ravaged land • Water contamination • Extraction uses natural gas • Low EROEI → Greenhouse gases EROEI = 3?
EROEI for Nuclear Plus … • Terrorism • Waste guarded for 10,000+ years • Depletion → low grade ores → Greenhouse gases … How do we value a 1,000+ year wasteland? EROEI = 4 12 ~ electric
EROEI for Hydrogen Am I missing something?! EROEI = ½
EROEI for PV • EPBT: 5 years • Life: 50 years • Plus it can be bootstrapped EROEI = 1030 ~ electric
