Corn Ethanol Worse Than Gasoline, but Biomass OK

There are 17 comments on the www.sciencentral.com story from Feb 6, 2009, titled Corn Ethanol Worse Than Gasoline, but Biomass OK . In it, www.sciencentral.com reports that:

It was known that producing biofuels from corn is no more efficient than producing gasoline. But now new research indicates that corn ethanol is also more harmful to human health and the environment. The silver lining: The researchers found that biofuels from non-food sources are significantly less harmful to people and the planet.

Saaay Whaat? Saaay Whaat? Cellulose is cellulose!
Fermentation breaks it down to ethanol while
carbon dioxide is a bi-product! When ethanol is
burnt in an engine the tail pipe emissions are still carbon dioxide, water, and heat! Significantly less harmful to people and the planet? Gosh and I thought that CO2, and water
were quite benign?

First educate folks that Industrial hemp can't get you high, was made illegal by those who were/are power-hungry, can not cross-breed successfully with its psy-active cousin pot.
Possibly not calling it marijuana would go a long way in clearing up some of the lies surrounding both cannabis hemp and cannabis pot.

We be back in a dark oil age. It is man who can prevent the disaster & man who can contribute to a disaster all for the sake of oil.

I totally agree. And ethanol is ethanol, they distill it for God's sake. What a load of crap. I can understand that cellulosic ethanol is harder to manufacture because of the lignin or whatever but how can they say that there's a difference of source when it's distilled?

what will save the planet and this country is well known. but we cant have any of that, it makes sense.

the break down of what can be extracted fom hemp is unbelivable. we can make plastic out of just one by product of hemp.

as for the marijuana aspect of it, tens of millions of americans smoke it. a tax base that would bring hundreds of billions into the economy. a huge tax base remains untapped.

Agreed. Education. Fortunately we have the Internet and you tube. Grass roots grow to Prairies.

The only way ethanol could potentially be more damaging to the environment is if it releases carbon based particulates in your engine that aren't broken within the catalytic converter. This occurs while burning wood and can actually lead to cancer of the lungs due to cellular damage if you are exposed to it for a long time. This is primarily a concern for people living in rural valleys, where smoke of houses heated by wood hangs in the air, and for people who just heat their house by wood in a poor furnace for a long time. A good furnace, one that gets hotter than 1000 degrees, breaks down these products and has no ill effects. I have absolutely no clue if this translates to ethanol, just explaining a way that it might.

Nothing new here. Stanford Prof. Mark Jacobson published the health problems with E85 in April 2007.

http://www.greencarcongress.com/2007/04/stanf...

Prof. Jacobson is way ahead on lots of pollution health issues of several supposedly 'clean' internal combustion engine problems. If Prof. Jacobson would research 'clean' coal, we'd have a major scandal erupt on the world stage detailing coal health problems.

But we already know about the health problems with coal and are taking steps towards cleaning it up. Scrubbers are routinely employed to get rid of all of the SOx emissions, eliminating acid rain. We use SCR and SNCR techs to eliminate NOx emissions, though this has yet to be implemented in many plants. We have come a long way from back in the day where particulate emissions were measured by putting a box out and seeing how long it took to fill with ash. We now measure it in average micrometers, sometimes even nanometers. With carbon sequestration, we may even eliminate CO2 emissions. So overall, I doubt we'd have a scandal, mostly because we do already know what we're putting in the air. The real question is which techs to use and how to implement them to reduce it even further.

Aero Engineer. You're talkin' old stuff. I say again, Prof. Jacobson is way ahead of you, addressing issues you haven't talked about, or even know about. He is researching, while you are blowing smoke about stuff decades ago (& which are NOT fully contained). Ya better see follow up on the Tennessee slurry pits, collapses, & ground leaching.

But this forum is on corn ethanol. To learn something, do further research on Prof. Jacobson.

all those farmers are sitting on a pile of corn, now they are broke.

sounds like it was the plan the entire time.

hosing all the farmers so they lose their farms and the government can control us even more.
