Ethanol may lead to more ozone-related deaths

[mikehanoo33]

Alcohol fuel has been added to gasoline to reduce virtually every class of air pollution. When using pure alcohol, the reductions in all three of the major pollutants—carbon monoxide, nitrogen oxides, and ­hydrocarbons—are so great that, in many cases, the remaining emissions are unmeasurably small. Reductions of more than 90% over gasoline emissions in all categories have been routinely documented for straight alcohol fuel.

[strantor]

Where do these figures come from? Made up? Didn't seem to explain how you came to these conclusions? And how do you justify saying that MORE deaths will occur? the only emissions from ethanol are CO2 and water! The increased amount of oxygen released from increased amount of crops growing would overcome the increased (which I don't believe there would be an increase) CO2 emissions.

Ethonol is not the future because the corn is going to be grown in mexico and other poorer countrys and will be sold to fuel companys therefore the people will have no food. The amount of ethanol that takes to drive from newyork to miami is enough to feed a mexican village for a year. Somebody is going to loose no matter what.

I have never met a man so ignorant that I couldn't learn something from him. I just learned that he spent all that money on education, and learned nothing more than how to conform!

[darkvader47]

It is difficult to get a man to understand something when his salary depends upon his not understanding it.

[darkvader47]

He's proof that a collage degree isn't worth the paper it's written on.

[cactuar04]

do you mean "college"?

[darkvader47]

This guy probably does a computer study before he has sex (assuming he likes sex) to see the percentage of sperm he shoots out from one day to the next.

[darkvader47]

The Oil company big wigs got to him. Another reason why our education system is shot!

[thremtopod]

Mark Z. Jacobson sounds like Kermit the frog.

[namniekib]

This guy is a perfect example of an environmental scientist with no economics education.Not everyone in the US can plunk down $30,000 for an electric car that has a range of only 100 miles or so.Ethanol,biodiesel and butanol are good solutions for the existing fuel driven infrastructure.Yes electric cars driven on renewables are the most ideal and with the advent of plug-in hybrids and better battery technology,that will become more of a reality.

[Juliusno1776]

Yes. I prefer not to kill the patient while curing him. We have to make drop in replacements to transition away from imported oil. Ethanol is one way. tinyurl com/56rrda

I am not sure this Professor is stating his case accurately. I have seen Ethanol studies that Ethanol pollutes 98% less than real world pump gas, which is filled with benzines, tolulene, etc. Google Mister, "Can You Spare a Paradigm?" Farmers can make 1/3 of what we need off corn on 120 million acres.

[darkvader47]

With electric cars we can look forward to higher electric bills and the hunger for electricity from the grids at night (now the electric company would love to raise your rates and have you dependent on them)unless we wait years for wind energy, which won't be a bad idea since it'll take us years to SAVE UP THE MONEY THAT WE DON'T HAVE TO BUY THE ELECTRIC CARS.

[ShredZeGnar]

Why was this video made?

[segarza]

The change to ethanol had nothing to do with air quality. It had to do with our dependancy on imported oil. Remember? Also, I bet there is just as many so called "experts" that will disagree with this guy. Who knows what the real truth is? Everybody is telling their own version of the truth. We are so screwed! See you all in Hell!  hehe

[Juliusno1776]

i respectfully disagree in part. I obtained well less than half the HC pollutants and from .01 ppm CO to .00 ppm CO in my own auto after switching to a 3/2 blend of E-85 and Pump gas tinyurl com/5nftmm Add a DOT and paste it into Your browser. You too can save money on fuel and direct over half your fuel dollars to Americans

Question:

How are you gonna generate all that electricity? The electricity required to make all this cars work?

If your Country, the European Union and most of the countries around the globe face the same problem???

Realistically and honestly... On a short term... What will they do? The British Premier was recently burned alive (lol..) by environment groups such as "Greenpeace" for planning to build new Coal and Nuclear Power Stations... How about America? Will you build Hundreds of them???

re: dantombrasil

--How are you gonna generate all that electricity? The electricity required to make all this cars work? --

Easy answer.

We'd could replace 84% the entire United States fleet of cars before we have to build even 1 new power plant.

Just have to use electricity at night when there's low demand.

Furthermore, high torque electric motors and high density batteries make renewable electricity.

Like Geothermal, Solar, and Wind, quite attractive for reliable electricity.

[greyflcn]

Wow, here's another scary thing on the biofuels.

greyfalcon. net/ biofuels

BioFuel Deforrestation is creating 10x more carbon than it's preventing.

[dantombrasil]

Hey... These goes the uninformed folks over there...

The sugarcane is far richer in ethanol then corn or cellulosic swichgrass and requires A FAR SMALLER AREA for plantation then any of this...

Anyway... It's been working for us for over 30 years! The technology is such, that it actually runs better and faster than a gasoline one!! And CO2 emission is close to NONE! Seeing is believing:

Search for: Making Ethanol Work and see for yourself!

[greyflcn]

Heh, if you want to talk area.

Lets say we compare sugar cane to 11% solar panels.

You get 50x more energy out of the solar panel, as compared to the sugar cane.

greyfalcon. net/ sugarsolar

This can then be used to power an plug-in hybrid which costs 50 center per equivalent gallon to fill up. Even when powered by the existing coal dominated grid, it's 45% greener than a normal car.

[dantombrasil]

That would be great friend... A car that would run as well and as fast as a gasoline or ethanol car or even to have an autonomy of 400 miles per battery charge...

And power stations to re-charge them...

I'm waiting for this day to come but on the meantime what do we do? What does the world do? Keep pumping CO2 into the atmosphere? NO! We gotta do something NOW! Use whatever green technology is available to us at present as well as researching and working on new and reliable technologies!

[greyflcn]

What are you talking about?

These cars are coming onto the market in the next few months.

And the place to charge up an electric car is anywhere that has a wall socket.

greyfalcon. net/ electriccars.png

We're gonna have electric cars up to speed far faster than we could ever hope to replace our oil supplies with biofuels.

Whats more it's cheaper to the consumer

Ethanol on the other hand, there's only 1 public E85 station in the entire state of California.

[Juliusno1776]

We can make 150 Billion gallons net as methane and ethanol on 20 million acres of waste land like empty gravel pits growing cattails on primary treated sewage. No prime crop land involved. CO2 can be used to boost cattail growth even more. Google "Mister, Can You Spare a Paradigm?" We use about 150 billion gallons of fuel a year for auto and piston aircraft. Less land area than 1.5% of the 1.3 Billion acres of total farm land. WE Can do it Today! No new technology needed.

[greyflcn]

Brazilian Ethanol is a joke.

greyfalcon. net/ brazil

And sugarcane ethanol where you only use the sugar is even worse than the cellulosic switchgrass they are talking about.

[dantombrasil]

Joke??? Don't really see how a joke can last over 34 years in a row... Joke, indeed is what the fossil fuels are doing to our planet!

[greyflcn]

It's a joke in that Brazil has hardly any ethanol as compared to their massive Oil drilling.

How can you call a country's fuels policy be used as a role model for sustainability when it pumps a comprable ammount of oil as Venezuela.  (Which supplies the US with more oil than Saudi Arabia)

[dantombrasil]

Well... we still use gasoline as any country of the world but I didn't think you really understood my point... 8 and I say: A Massive 8 out of 10 CARS use Alcohol Ethanol but we still have a large amount of Trucks, Coaches, Heavy machineries that use Diesel... But hey, we already have over 2000 Petrobras petrol stations dispensing Biodiesel across the country! So, We are also turning to them! It takes time but we are getting there I think!

[dantombrasil]

Together these two giants will benefit countries with the implantation of power plants, training, as well as with the necessary investment in order to create many, many jobs in those nations!

Plus... Mother earth will thank us "if" we use the green and efficient SUGAR CANE ETHANOL, Biodiesel, eletric energy, solar energy in a massive scale!!!

Come and share this vision! It's no longer a dream... It's reality knocking at our doors! Will you welcome it? It's your call...

[dantombrasil]

(sorry... the above last two lines were a mistake...)

Continues... We being the World's 8th largest economy (GDP 2007) and a Nation that is helping to rebuild and to keep peace in Haiti do strong believe in Freedom and work to the people of war-torn and desolate nations!

The United States of America, our long time ally and partner is also sharing in this vision for...

[dantombrasil]

Despite Brazil being the world's leading country in biofuel technology as well as self-sufficient on petrol... Being a Nation of the FREE WORLD, a Democratic Nation, a Nation the has fought many wars side to side to our allies against tyranny of the world oppressors do want to set the world free of the oil tyranny and not only so...

to our allies do strongly oppose the greed of the International oil-rich tyrants for we do not only wanna share our high-tech to the world

[dantombrasil]

"Corn" Ethanol... That's where the mistake is! Our Scientists in Brazil have been studying the genetics of the sugar cane plant for well over 30 years and the international science community agree on something very important:

The sugar cane ethanol releases close to none co2 on the atmosphere and the little it releases the plantations of sugar cane itself do absorb it!

[greyflcn]

Really suprised by how the net CO2 emmisions go down by only 4% when using switchgrass E85.

[lucyblue86]

Pure genius, as always!
