Gasoline is not only expensive, it is harmful to you health. We review the effects of lead, and MTBE additives that were in gasoline. Both harmful to your health. Currently, gasoline, now called reformulated gasoline, contains 1 percent benzene. Chronic exposure to relatively low levels of benzene significantly increases your chances of getting leukemia.Your exposure comes in three ways: when you are filling up, through the build up of emissions from engine combustion, and through the additional emissions created by the three-way catalytic converter. We show the way to get off gasoline and diesel. The answer, the only answer, is to run our cars on alcohols. Don't get hung up on the corn ethanol/food/water issues. It only one of a number of possible alcohol choices, and ethanol can be made in other ways -- as we discuss. But the real answer is to use methanol with some ethanol. The majority of methanol will initially be made from natural gas, and then we will move to organic wastes, and then to farm grown algae. We are the Saudi Arabia of wastes. Methanol can also be made 30% more efficiently using the sun and CO2. We go over these options. You will be wealthier, healthier, independent of OPEC, and you will have more fun driving. Make you voice known.

Rapid Societal DeathOur commerce, and American life as we know it, would stop on the dime, if OPEC wanted it to.
Gasoline additives and our health During WWI, it was discovered that you can add a chemical called tetraethyl lead to gasoline and significantly improve its octane rating. Low level exposure to children: Lowered IQ, reading and learning disabilities, impaired hearing, hyperactivity, impaired growth. Acute exposure in adults: Blindness, brain damage, kidney disease, cancers, death Prohibited because it destroyed catalytic converters!
MTBE replaced lead in so called Reformulated Gasoline (RFG) MTBE has been used in U.S. gasoline at low levels since 1979 to replace TEL to increase its octane rating and help prevent engine knocking. It was used in combination with aromatics like benzene and toluene. Gasoline can contain as much as 10 percent to 15 percent MTBE. Gasoline may contain up to 50% aromatics The main problem with MTBE is that it is thought to be carcinogenic and it mixes easily with water.
Benzene: It gets to you in more thanthe fumes you breath when you fill up We all know about the filler cap regulations, but, the benzene emissions that result from the catalytic converter acting on the emissions is 2 orders of magnitude worse when the car is either cold or is accelerating. At the minimum turn your head away from the pump.
Benzine risk for Leukemia WHO: 1 part in a million is considered acceptable. In 2001 EPA estimated that we had 10 X this limit in the US. 2005 Swiss study calculated that 100x is emitted from the tailpipe of an accelerating vehicle.
What did we replace the MTBE with - Ethanol Ethanol is OK health wise Ethanol made from corn has many problems Ethanol can be made from other sources Other alcohols can supplement it. Methanol. BIGGEST problem: vehicles are designed with gasoline as the standard, making alcohols poor substitutes
We must get rid of legacy practices and procedures In moving forward sensibly we must have a plan for the future In moving forward we can wean ourselves from oil gently, but with the full intent to wean ourselves For all of the reasons given, we must make gasoline and diesel less and less of the fuel mix we use. So in our transition we must focus on oil in the future as an additive, NOT as the standard we are modifying.

Electric Cars Excessive costs High CO2 limited range WTW GHG worse than gasoline ---- coal Nuclear not happening in the next few decades Natural gas burned to make electricity vs. used directly or converted to a liquid (methanol/ethanol) 60% loss at power plant + 7-10% in transmission Battery costs Range Durability Safety Every decade a 10% improvement is made in batteries
Fuel cells PEM -- very high costs, but can work with methanol DMFC even higher costs methanol fuel SOFC lowest costs lowest reliability can use methanol Bottom line: 2 decades for SOFC,and discovery for the PEM and DMFC
CNG proponents sloganClean, Abundant and American -- YES Affordable -- NO.
Storage tanks in a CNG automobile $7,500 - $12,000 additional costs
24 / 7 CNG self serve pump for cars on the UCLA campus $300,000 to $500,000per dispenser to install
Costs to US to replace gasoline with CHG/LNG It cost about 100x as much to convert to CNG/LNG as it does to make a Flex Fueled car that can use any combination of gasoline, ethanol and/or methanol. Our gross national debt is ~ $14 T, our gross national product is ~ $14T, CNC/LNG would cost ~$3T, or, 21.5% of GNP The interstate Hwy system cost 1.4% of GNP in 1958 Peak WWII spending was 44% of our GNP CNG/LNG is NOT a societal solution
What CAN we do?
Drop-in liquid fuels are the way to go If drop-in is not feasible, then liquid fuels that need a minimal modification GM has produced four million of the eleven million flexfuel cars now on American roads. GMs Vice Chairman Tom Stephens says it adds "as much as $70 to the production cost" of a car to make it a flexfuel car. Thursday May 26, 2011Institute for Energy Resourcefulness 5/30/12
Why not Alcohol? Henry Ford made the Model T both alcohol and gasoline compatible for 2 decades.Until (Rockefeller supported) Prohibition
Ethanol Economy Strong proponents Water usage Corn States Brazilian sugarcane industry Fertilizers Equatorial belt countries Biomass limit Sources: Wheel to well CO2 Sugarcane and starch (corn) Cellulose Overall economy Natural gas Feedstock is 80% Performance Tail pipe emissions ICE and Diesel Toxicity and Flammability Fuel Cells DistributionThe Biomass limit means that ethanol made from crops can only meet 20-30% of our needs
Ethanol/Gasoline Vehicles that getMORE power and BETTER mileage
Proof of the pudding ICEs can run better on alcohols Saab Biopower line By reprogramming the on-board computer By using a turbocharger to increase the CR of the engine By changing the fuel system components to handle alcohols Saab increased the HP of their 2liter, 150HP engine, to 180HP At the same time they increased the torque by 40Nm
Saab performance curvesRON research octane no.
A further example The Dutch Koenigsegg CCXR gets 1/3 more power running on E85 over its gasoline model.

A big step further E100 Saab E100 Using 100% ethanol, and optimizing the engine for it, Saab took a 2 liter 150 HP engine and had it output 300 HP. EPA showed that a VW TDI diesel engine could run more efficiently on 100% methanol or 100% ethanol. Could manufacture engines more cheaply than diesels MIT pointed out that a 15 liter engine could be replaced with a 7 liter engine.
Ethanol can give engines diesel engine efficiencieswithout the need for high pressure injection systems and either DPF or Urea NOx reducing exhaust treatment. Diesel Spark ignited E100 We can replace diesel engines with equally efficient alcohol run spark ignition engines, and not need the particulates, NOx or bio-diesel.
At E30 the mileage in an optimizedengine is better than with gasoline alone Combined with an optimized conventional drivetrain, the efficiency gain shown in the previous slide for E30 should yield an estimated 10% - 12% gain in fuel economy. Thus it more than compensates for the approximately 8% loss in fuel energy density of E30 vs. straight gasoline. EPA
Swedish diesel busesrunning on 95% bio-ethanol has been running for 15 years
Ethanol has 2/3 the energy per unit volume of gasoline
Progression of E85 fuel economy in US cars Because ethanol contains less energy than gasoline, fuel economy is reduced for most 2002 and earlier American FFVs by about 30%. Most after 2003 lose only 15-17% or less. Some of he newest American vehicles achieve only a 5-15% loss.
Are we being manipulated by business directed engineering? In one test, a Chevy Tahoe flex-fuel vehicle averaged 18 MPG [U.S. gallons] for gasoline and 13 MPG for E85, or 28% fewer MPG than gasoline. In another test, however, a fleet of Ford Tauruses averaged only about 6% fewer miles per gallon in the ethanol-based vehicles as compared to traditional, gas-powered Tauruses. The Honda Civic FFV, in Brazil, when running on E100, generates 140HP at 6,200 rpm and 174 Nm of torque at 4,300 rpm. Fill it with an E22 mix and those numbers only drop to 138 HP and 172 Nm (this torque peak arrives at 5,000 rpm). With the Honda Fit FFV, in Brazil, on E100, it makes 83 HP at 5,700
