STUDYMatthew Simmon’s Presentations on Saudi Arabian Oil (www.simmons-intl.com)and his new book “Twilight in the Desert”  John Wiley & Sons publishers, May 2005: 

STUDY Matthew Simmon’s Presentations on Saudi Arabian Oil (www.simmons-intl.com) and his new book “Twilight in the Desert” John Wiley & Sons publishers, May 2005 Also Google “peak oil” and look at sites such as “peakoil.com” When Saudi Arabia Peaks So does the World. GHAWAR, by far the world’s Largest and most prolific oil field may have already peaked. The days of cheap oil are over.

Slide5: 

Global warming over the past millennium Very rapidly we have entered uncharted territory -– what some call the anthropocene climate regime. Over the 20th century, human population quadrupled and energy consumption increased sixteenfold. Near the end of the last century, we crossed a critical threshold, and global warming from the fossil fuel greenhouse became a major, and increasingly dominant, factor in climate change. Global mean surface temperature is higher today than it’s been for at least a millennium. Slide from Marty Hoffert NYU

PRIMARY ENERGY SOURCESAlternatives to Oil: 

PRIMARY ENERGY SOURCES Alternatives to Oil TOO LITTLE Conservation / Efficiency -- not enough Hydroelectric -- not enough Biomass -- not enough Wind -- not enough Wave & Tide -- not enough CHEMICAL Natural Gas -- sequestration?, cost? Clean Coal -- sequestration?, cost? NUCLEAR Nuclear Fission -- radioactive waste?, terrorism?, cost? Nuclear Fusion -- too difficult?, cost? Geothermal HDR -- cost ? , enough? Solar terrestrial -- cost ? Solar power satellites -- cost ? Lunar Solar Power -- cost ?

World Energy Schemefor 30-60TW in 2050:The Distributed Store-Gen Grid: 

World Energy Scheme for 30-60TW in 2050: The Distributed Store-Gen Grid Energy transported as electrical energy over wire, rather than by transport of mass (coal, oil, gas) Vast electrical power grid on continental scale interconnecting ~ 100 million asynchronous “local” storage and generation sites, entire system continually innovated by free enterprise “Local” = house, block, community, business, town, … Local storage = batteries, flywheels, hydrogen, etc. Local generation = reverse of local storage + local solar and geo Local “buy low, sell high” to electrical power grid Local optimization of days of storage capacity, quality of local power Electrical grid does not need to be very reliable Mass Primary Power input to grid via HV DC transmission lines from existing plants plus remote (up to 2000 mile) sources on TW scale, including vast solar farms in deserts, wind, NIMBY nuclear, clean coal, stranded gas, wave, hydro, space-based solar…”EVERYBODY PLAYS” Hydrogen and methanol are the transportation fuels

Enabling Nanotech Revolutions: 

Enabling Nanotech Revolutions Photovoltaics -- drop cost by 10 fold. Photocatalytic reduction of CO2 to methanol. Direct photoconversion of light + water to produce H2. Batteries, supercapacitors, flywheels -- improve by 10-100x for the distributed Store/Gen Grid, and automotive applications (especially plug-in hybrid vehicles). Power cables (superconductors, or quantum conductors) with which to rewire the electrical transmission grid, and enable continental, and even worldwide electrical energy transport; and also to replace aluminum and copper wires -- particularly in the windings of electric motors and generators. H2 storage -- light weight materials for pressure tanks and LH2 vessels, and/or a new light weight, easily reversible hydrogen chemisorption system (material X). Fuel cells -- drop the cost by 10-100x + low temp start + reversible

Slide22: 

The biggest single challenge for the next few decades: ENERGY for 1010 people . At MINIMUM we need 10 Terawatts (150 M BOE/day) from some new clean energy source by 2050 For worldwide peace and prosperity we need it to be cheap. We simply can not do this with current technology. We need Boys and Girls to enter Physical Science and Engineering as they did after Sputnik. Inspire in them a sense of MISSION ( BE A SCIENTIST SAVE THE WORLD ) We need a bold new APOLLO PROGRAM to find the NEW ENERGY TECHNOLOGY

The Nickel & Dime Solution: 

The Nickel & Dime Solution For FY05-FY10 collect 5 cents from every gallon of oil product Invest the resultant > $10 Billion per year as additional funding in frontier energy research distributed among DOE, NSF, NIST, NASA, and DoD. For the next 10 years collect 10 cents from every gallon; invest the >$20 Billion per year in frontier energy research. Devote a third of this money to New Energy Research Centers located adjacent to major US Research Universities. At worst this endeavor will create a cornucopia of new technologies and new industries. At best, we will solve the energy problem before 2020, and thereby lay the basis for energy prosperity & peace worldwide.
