The scam of corn ethonal

Re: The scam of corn ethonal

This thread is not about extrapolating which the best alternatives are; the focus is on the corn ethanol industry and what it is doing.

Well then unless we have a bunch of farmers on the board it's going to be a short discussion because no one else is going to argue in favor of the industry.
 
Re: The scam of corn ethonal

I'm curious how much power we can harvest from algae. Not mathematically, but logistically.

I've heard a lot of talk about tidal power, but that's never come to fruition.

Its not so much you want to harvest the algae as you want to extract the oils from the cell structure. Mechanically this is a very energy intensive process, BUT there are companies such as origin oil which are using ultrasonic waves to separate the oil from the algae. As a side note, I had to do this manually when I was running gas chromatographs on lipid structures of algae, and it was a HUGE pain the ***. A rapid throughput method to extract oil from algae would drastically improve the large scale feasibility of microalgae as a biofuel feedstock.

And yes, algae are the top hope for biofuels. Short reason list is that they grow anywhere, produce high yields and the oil quality surpasses petrol. Yes, its energy content is higher. A jetropha/ algae blend actually powered a test flight last year. You don’t throw bad fuel in an airplane and have it fly!
 
Re: The scam of corn ethonal

Sounds like I could get rich if I turned my backyard into an algae farm :p

Priceless, allow me to elaborate more on algae: the air force is willing to buy a gallon of algae fuel for something like 60 dollars. That’s good. But in order to get that, you need the growth controls, land space, algae harvesting, fuel separation, and distilling process to get there. Without sophisticated process engineering/ know how, you’ll easily spend more than 60 $ per gallon producing the stuff.

In fear of being hypocritical from before, I don’t see algae fuels taking off without subsidies. Here is why. The return on investment on a production scale might be 5 years, and the cost will easily be in the millions. This eliminates any angel investment or venture capitalists who are interested in maturing the technology. Craig Venter of synthetic genomics is doing it right and has a 600 million dollar lifeline from Exxon to help them produce synthetic organisms. Yes, it’s the oil companies, but at least its progress…

However, imagine this. Utilizing microalgae as wastewater nutrient sequestration agents WHILE producing biofuels. Yes, algae will eat anything including harmful nitrates and carbon dioxide. While I believe carbon sequestration is a joke, studies done in the 80s shown that a functional algae system could eliminate up to 6% of carbon assuming a good diffusion system. Also know that algae can grow in the crappiest water known to man. It will NOT impede on clean drinking water and might actually be able to produce more. Now imagine that it is theoretically possible ( key word here folks) to produce all domestic oil concerns in a size of land the size of Maryland and get more clean water….suddenly algae become attractive if we put our efforts to it. However, a synergistic and congruent engineering effort to utilize the best in class technologies will be needed to make production realistic. Its not yet, but the upside to me looks good.
 
Re: The scam of corn ethonal

1- Rising food prices. Don't care what the pundits say, its very real. Anyone who has done the research into Ethanol production would know that it actually COSTS more to make on a per energy basis. Congrats America, you are paying at least 7 billion dollars per year for this! Green energy idiots would prefer to look at the end product, whereas any astute observer would look at the cost on a lifecycle basis. Corn ethanol fails, massively, here.

http://www.businessweek.com/news/20...s-ebb-heightening-food-inflation-concern.html

We have seen a 5% jump in food prices this year, at least. We produce at best 3% of the energy's oil needs ( thanks E10), but take up at least 1/3d of the crops which could go to food. Not sure thats a good tradeoff.

2- Pundits will state that ethanol production will reduce the demand for regular petroleum. Fact is, this isn't true. Period. Actually it makes sense that the E15 mandate would be a strong issue, because a FALLING demand for petrol actually hurts the Corn ethanol industry.

I am stating up front, I'm not a fan of subsidized ethanol. I'd prefer it be stopped.

That said, and I'm not playing devil's advocate here as much as railing against incoherent babble, but this is about the most rambling, incoherent use of statistics to rail against ethanol that I've seen. You're throwing numbers out there and not just comparing apples to oranges, but comparing apples to exotic widgets from Galaxy 572Xy of the alternate universe with evil goatees.

Food prices are up 5%.
We produce 3% of the world's energy (without E10 we'd produce more? less? or are you saying ethanol = 3% of petrol needs? seriously, what the fark are you talking about here).
A 1/3rd of our crops are going to...ethanol production? What crops? Corn? Just the grains? All crops?

What's the size of the world's energy market? What's the size of the world's food market? Is 3% of the world's energy market worth more than a 5% increase in food prices? How much of the increase in food prices is due to one-off events (bad wheat harvests in Russia/China, floods in Japan, etc.) versus ongoing ethanol policy? How much is due to a recovering eceonomy and the resulting increase in all energy costs?

3- The energy (BTU/gal) is 2/3 that of petrol. What does it mean in laymen speak? This means that you will get less energy per unit volume when utilized. This means if you wanted to displace 1 barrel of oil say, than you would need to actually use 1.5 barrels of Corn ethonal.

Which, again, is neither here nor there if the goal is reduce dependence on foreign oil and/or reduce the use of fossil fuels. You have an efficiency argument, but not one that goes against the need to find viable alternatives to oil within the next 50-100 years and get the infrastructure up and running to support it.

4- The subsidies ethanol receive on a per energy basis are much higher than that of natural gas or oil. Yet the later produce much more energy and don't infringe on land space, or food prices. I don't have this number handy but if anyone really cares I can dig it up later.

Those are policy arguments with more efficiency ones thrown in. So...great, I guess?

5- Corn ethanol’s makeup is such that when introduced to an older mechanical system, it will actually corrode the components. If E15 passes, prepare to have to replace your lawn mowers, boats etc sooner than before.

Because there clearly won't be a phase in period, and people have never had to change older equipment for newer ones in the past thanks to government regulations (I'm thinking specifically of the transition from analog to digital TV's, for instance).

The problem here is just how out of tune our acting congressmen/ people of power are.
Maybe they'd listen more if you could throw together a structured, coherent position rather than a rambling wreck of a rant.
 
Re: The scam of corn ethonal

You missed the point by a few astronomical units, won’t even bother replying to your points. They are too dumb to address.

Don’t argue with idiots. They bring you to their level than beat you with experience.
 
Re: The scam of corn ethonal

photosynthesis isn't all that efficient, something nearly 10%. Any plant into ethanol is a losing proposition. Making methanol from pulp wood before using it for paper might work, UMaine has been trying to do this, so far no big breakthrough.

Tidal is working in Cobscook bay, one company has had a prototype in the bay for a while. I think they are building a larger unit to test this summer. Permitting is going to be a huge issue as they want these units in traditional lobster fishing grounds .

UMaine is close to getting the money to build a full scale test wind mill that will either float or be anchored in the gulf of Maine, cost of 3 or 4 million.Should be running by 2013-14 according to the stuff I've read. A giant Wind Farm out there makes all the wind farms on land a joke. The wind blows constantly out there and the amount of energy there is many nuke plants in comparison. They hope to have the wind farm operational by 2030. The amount of money to do so is still a huge problem but if the test works out I expect it to go.


One more thing, hasn't E 15 already passed? You may ask why 15%, because that's what current piping, tanks and pumps can take without being replaced

Unless your point is "ETHANOL IS BAD WHARGBL" - you didn't have a point.

For better or worse, the ethanol industry has a clear, concise message and they stay on point. You're never going to beat them until you can do the same.

Edit: Also, seriously? You neg repped me? So apparently UNH fans don't just whine at referees, they just whine in general.

Actually, E20 was recently allowed. but that means that you can pump E20 into your car from a pump that is NOT labeled as E20.

for the most part, what you pump into your cars is E10. E15 and E20 w/o a label would probably be only available where E85 is common.

Not that I know yet, and its being violently opposed. Actually you might get a good chuckle if you saw the list of entities signing the petition against corn ethanol. Yes, there are oil interests and the sierra club on the same petition! The enemy of my enemy is….the enemy of the corn?

The blue/green microalgae like chlorella vulgeris are , at best, 7 % efficient..maybe? I’d have to dig up my numbers, but its something like that. The problem with cellulosic is extraction is even more costly ( on an energy basis). Also, the term ‘renewable’ is obviously subjective. Some people think clear cutting trees, or growing vast swaths of cown are renewable, but the fact is large tracts of land and a lot of wildlife suffers from either scenario. The beauty of algae is that is really is renewable. Tests show inoculated cultures double in size within 24 hours and can sequester up to 80% of certain pollutants in 48 hours! That’s not only renewable, its friggan fast!!

Also interesting take on the wind. Offshore is more efficient, but you cited costs as a big deal. True. Also remember how corrosive salty H2O is. If it works though, I’d be thrilled. Now, if only we can store electric energy better…..
 
Re: The scam of corn ethonal

Californians could start glowing in the dark?

Hey, that would reduce our electricity needs! Let's do it!

Let's not forget, while we're using the Japan tragedy to our greenie political advantage, that the design of the Fukushima plant was considered so unsafe when it was built 40 years ago that one of the GE designers resigned in protest and published information forecasting exactly what would take place when a tidal wave knocked the power out.
Apples vs. oranges compared to today's designs, or any American design over the last generation.

Wood will play a promient role in the structures holding the turbines so rot not corrision may be an issue. He wants to build every thing in Maine, right now most turbine blades are built in other countries and brought here.

I know Maine and New Hampshire had major issues with piping when E10 was introduced. Lots of money was spent upgrading piping to stuff that was listed for E10. I thought a commonly used pipe wasn't listed for E85 but it is. Not sure about early editions of dbl wall fiberglass? E85 definitely takes a special pump, stainless steel anyplace fluid is carried. My understanding is anything over E15 will kill a regular gas pump, in other words leaks, meters not working correctly etc.

My comment was a sarcastic response to Nancy Grace, who seems convinced (and wants to convince her viewer) that the radiation from Japan is going to render Californians incandescent. Odd that she doesn't seem concerned about Alaskans, Hawaiians, Washingtonians or Oregonians (or the Japanese themselves).
 
Re: The scam of corn ethonal

Every available energy source has a trade-off, both environmentally and economically. To me, the question of how to balance those isn't a science question, but a policy question.

I don't know the "correct" answer, but I do question, in general, the logic behind giving subsidies to corporations and if that is actually money well spent.
 
Re: The scam of corn ethonal

To be fair on the food prices thing, the federal government is still paying farmers not to grow corn. This essentially creates a price floor and prevents farmers from undercutting each other. The Department of Agriculture has a practice they started in 2007 where will be paid half of your subsidy to not farm, to farm but on the condition you only sell to a buyer that will use the said corn to produce ethanol. Brazil is the #2 producer in the world of ethanol and while the free market has been very good them, it's killed the environment through all the massive land clearing that has been done in the Amazon.

Using bio-diesels from algae growth seems like the next big thing to come along. While the energy retention rates are better than ethanol, there's talk that the way the fuel is synthesized it can be more efficient if engines are developed specifically for the algae bio-diesel.

One of the most under-utilized power sources that could really help in the western United States is geothermal power. Countries like Iceland and Norway have a considerable percentage of their power from geothermal springs and it's very efficient in comparison to coal and solar.

In theory, E20 is ok, too. I know it's been tested, but am not sure to what extent.

Again, it's about what they are NOT telling you- they can have UP TO E20 without a label on the pump. But virtually all states have E10, and any state running California LEVII rules are running E10 for sure (since MTBE has been banned).

I would be stunned if you found anything more than E10 in Maine, unlabeled.

oh.
I read about how here on the other side of the world, drug stores are sold out of iodine pills. Stupid people aggravate me.
