Mark Jackson, an atmospheric chemist from Stanford University,has recently released a report on the effects of E85 (85% ethanol, 15% gasoline) on the atmoshpere.


http://pubs. acs.org/subscrib e/journals/ esthag-w/ 2007/apr/ science/ee_ ethanol.html

In his study he found a slightly higher rate of Ozone polution which would potentially cause an increase in asthmetic problems. He speculates that there would be an increase in deaths related to such respiratory illnesses.

comments?

Ethanol was pushed by the corn lobby. They used the fervor over environmental conservation to bolster their argument.

Thanks Andre...your advice worked..kind of. I have the adress correct but it is not clickable. Must have messed up somewhere.

See...Im not just a latecommer to Geology, but to technology in general :(

Doug,

Your browser had decided to put in spaces at random.

Clearing the air on ethanol

New research predicts that E85 vehicle emissions could cause just as many deaths as gasoline, or more.

Hi Doug.... if you're in California, you're on the same Hydrogen Hiway as British Columbia!!!. Right up to Whistler for the 2010 winter games!

As for Ethanol. We've had a 90/10 split type of gas here for about 20 years. The ethanol comes from a specific source such as corn or GM cannola oil.

The 10% ethanol gets you 25% cleaner burn from your gas and you are able to pass the controls.....Air Care...... every year as long as you burn the crap out with the 10% Ethanol first!

I don't have the data for Ethanol and the emission status.... let me look for a second....

Nice source..... the Canadian Broadcasting Corporation.....

Quote:
When organic material ferments naturally, the liquid that's produced contains about 15 per cent alcohol. Do it in the lab and the alcohol content skyrockets. Ethanol is almost pure alcohol. In the 1850s, ethanol was widely used as a fuel for lamps. But during the Civil War, the U.S. government slapped an alcohol tax on ethanol to raise money for the war effort. The tax made it way too expensive to burn ethanol as a fuel.

The U.S. Department of Energy estimates that it would cost $113 US more a year to run a Ford Taurus on E85 than on gasoline. But at the end of that year, the Taurus running on E85 would have produced 1.5 tonnes less greenhouse gases than the Taurus that relied on gasoline.

However groups like the Sierra Club of Canada point out that while more ethanol and less gasoline makes sense, it has to be the right kind of ethanol. The environmental group says it takes five hectares of cornfields to produce enough ethanol to run a car for a year. The same land could feed seven people for a year.

the Sierra Club lauded both the Liberals and Conservatives for committing to a National Renewable Fuels Standard setting a minimum of five per cent mix of biofuels in gasoline and diesel by the end of 2010. But it urged both parties to switch from relying on ethanol derived from corn and grains to ethanol produced from waste straw and wood chips. The organization argues that producing ethanol from those sources doesn't take farmland out of food production and achieves greater reductions in the emission of greenhouse gases.

American farmers are expected to devote 3.2 billion bushels of corn to ethanol, an increase of 49 per cent over last year. Demand for corn has pushed prices to their highest point in a decade, and experts say consumers should expect to pay higher prices for a whole range of food products at the grocery store.

Jyoti Sahasrabudhe, a Calgary-based food industry analyst, says food manufacturers have long favoured corn as an ingredient for its versatility. For example, cornstarch is used to thicken chocolate milk while corn syrup solids are to increase the shelf life in frozen foods.

"We need to find that balance between fuel sources and food sources, and if we can't afford the food we eat, we have no need for vehicles," Sahasrabudhe said.

But this may be the fumes of Ethanol before its combusted..... right along the lines of Gasoline sniffing.....

Go Hydrogen (generated by solar power and chemical reactions).... or go Fuel Cell + Solar! There are a number of households in Japan off the grid and on their little fuel cell generators right now. What happened to us... the people who invented the damn thing?!!

Thanks!

I was in traffic with a Ford Hydrogen Fuel Cell Vehicle today. Its totally unnoticable except for the decals all over it declaring it to be a FCV. Its like the design for the Ford Focus sedan.

There was water coming out of the exhaust and it drove silent but powerful. The city has its emblem on it as does the Ca. Govt. along with just about every company that's putting effort into the endevour.

The "hydrogen highway" is an idea that started with former Prime Minister of Canada, Paul Martin who pitched it to Arnie, Governor of California. The idea is to have H stations dotting the I5 up to at least as far as Whistler Village in BC. This is about 1500 miles and a small stretch for Fuel Cell kind. Each station, at some point in the future, should cost as little as $250,000 usd to build and begin operation. Each vehicle probably costs the same or more.... but, so did a lap-top at one time.

If Ford is finally able to see past the next 15 years and latch on to a technology that promises to be the next unoffensive propellant of the future.... that's great. That will give Ford a double whammy in history: perfecting the car and assembly line and perfecting the technology behind the Fuel Cell Vehicle.

You know why Arnold is pushing the hydrogen highway don't you? His environmental policy was written by Robert Kennedy Jr. who has major ties to the NRDC. We get our hydrogen from natural gas and Arnold, Kennedy and the NRDC have investments in natural gas.

A few years ago natural gas prices tripled. I don't know what they have done since but we are not building pipelines and we won't allow the offshore hubs to ship it in. Where does that leave us if we start using it for hydrogen production? Shortages, higher prices and major money flowing into Arnold's, Kennedy's and the NRDC's pockets.

BTW, the NRDC is responsible for bringing us MTBE. Clinton gave an executive order absolving them of liability.

What is the MTBE?

Hydrogen can be extracted from pretty well anything. Methane, ethanol, water, nickle plating process, there's 500 chemical processes that generate hydrogen. If its the energy it takes to do so that is a concern, solar and wind are cheap, re: used to be free!.

I think there is a misconception with the whole hydrogen thing. Its not being used as a fuel. Its generating an electrical current when it passes through a membrane. This is why its called a fuel cell battery. There is also the possibility of renewable hydrogen so that the system becomes closed requiring little input.

Quote:
In principle, a fuel cell operates like a battery. Unlike a battery, a fuel cell does not run down or require recharging. It will produce energy in the form of electricity and heat as long as fuel is supplied.
A fuel cell consists of two electrodes sandwiched around an electrolyte. Oxygen passes over one electrode and hydrogen over the other, generating electricity, water and heat.
A fuel cell produces electricity.



Here's how Hydrogen Fuel Cells work

http://www.bullnet.co.uk/shops/test/hydrogen.htm

Besides, Arnie will not last as long as the fuel cell technology. With his and many other greedy little hands in the bucket gone (over time) the technology will still be here....... and even better....... and this is something that is really quite exciting. Mobility without toxicity. And without noise pollution to boot!

    MTBE

      Methyl tertiary-butyl ether (MTBE) is a chemical compound with molecular formula C5H12O. MTBE is a volatile, flammable and colorless liquid that is highly soluble in water. MTBE has a minty odour vaguely reminiscent of diethyl ether, leading to unpleasant taste and odour in water. MTBE is a gasoline additive, used as an oxygenate and to raise the octane number, although its use has declined in the United States in response to environmental and health concerns. It has been found to easily pollute large quantities of groundwater when gasoline with MTBE is spilled or leaked at gas stations. MTBE is also used in organic chemistry as a relatively inexpensive solvent with properties comparable to diethyl ether but with a higher boiling point and lower solubility in water. It is also used medically to dissolve gallstones.

      MTBE is manufactured by the chemical reaction of methanol and isobutylene. Methanol is a derived from natural gas, and isobutylene is made from crude oil or natural gas, thus MTBE, as used in motor gasoline, is a fossil fuel. In the United States, it was produced in very large quantities (more than 200,000 barrels per day in the United States in 1999) when it was being used widely as a fuel additive there. Because of widespread releases of MTBE-containing gasoline from Underground Storage Tanks all over the US, various jurisdictions banned the use of MTBE and production was reduced. MTBE contamination in drinking water aquifers is a serious concern in many states (most famous cases are Lake Tahoe and Santa Monica). By late 2006, most American gasoline retailers had ceased using MTBE as an oxygenate, and accordingly, US production had declined. Similarly, lack of growth or even decline of MTBE production has been seen in Western Europe. This not because of environmental reasons; on the contrary, it is because the alternative ethanol-derived ether ETBE has been given more favorable tax treatment. Nevertheless, in other parts of the world, which account for about a half of 2004 production, the use of MTBE will continue and even grow.


Here is a link to a friend of mine's post discussing the CA energy crisis and the scam being run. He uses MTBE as an example of how the scam works and even briefly covers why Kyoto was pushed so hard. Long but interesting read if you can get around the feeling of coming into the middle of a conversation.

His post is still relevant when you start talking about global warming and the money being used to push it etc. I show people this so they will understand the politics behind what is going on.

So is the big conspiracy to make a bunch of money and spend it in the remaining but shrinking little reserves of habitable areas on earth until there's nowhere left.... then die?... Sounds like it.

I've worked for private environmental assessment firms that are used by mining companies to stave off the govt. and its regulations. Hello... big money under the table, great big money.

But some of the benefits for the affected communities look great on the surface. Once you calculate the long term benefits, there's really nothing in all of this for anyone... with the exception of a few Rockafeller-sized bank accounts "off-shore". The same is true with corn etc... agriculture for Ethanol. Short term it looks good for the producer... long term... we're driving around using up 7 people's dinners every day in our tank, funding and supporting genetic modification techniques, and the complete ruin of bee colonies and naturally bred corn plants through cross pollination and neonicotinoids-based pesticides...

Quote:
These substances belong in a class of chemicals called neonicotinoids (neeoh-nic-it-ehnoids), “systemic” pesticides which when applied to seeds, are absorbed into and through the entire plant. So when an insect, like say a honey bee, feeds on let’s say it’s pollen or nectar it can get a dose of a neurotoxin that can effect the bees nervous and immune system. This then can disorient the honey bee. Disoriented, they buzz around in a chemical fog and cannot make it back home. If a bee is away from the hive for about a day it will eventually die.

This pesticide was banned in France in 1999 for just this reason. Beekeepers suspected it was the culprit behind drastic and mysterious honey bee die offs, but they were more creative with their title and dubbed it “mad bee disease.”


http://www.thedailygreen.com/2007...-look-at-bee-disease-report/4540/

This is what we are looking forward too if we rely on a growing, limited source of ethanol. I think I've already sited advocates of using waste lumber, wood chips, trees ruined by pine beetle, grass clippings and other organic waste as sources for ethanol. Otherwise, hello fuel cell power, solar, wind... other.
