im not to sure if that means under the current process or what. the second article says 65% net loss of energy by using ethanol.
While I'm not an expert here, I'd think that these are some good questions that need to be addressed when substantiating this report
Quote:
I just wonder if the good Doctor has updated any of his information. Dr. Pimentel has been a naysayer of ethanol for a number of years, both due to a lack of ag background or the ability to research the same. His last study was plagued with outdated information on almost every angle. His corn yield numbers are from 1992, why not today? His ethanol yield data was from 1979, severely outdated. His numbers for energy required to produce fertilizer are from 1990. He assumes all corn is irrigated, only 16% is, and he assigns no energy credit to one of the co-products of ethanol - distillers grains. Distillers grains are a high protein, high value livestock feed. Please also consider the other comments in just how far off he is in modern day production costs on the farm! Last year we consumed less than 2% of the corn crop as food - I don't think ethanol is starving the world!
It has been my impression that the good Doctor knows that his anti-ethanol jargin will get published, as it goes against the grain. It is sad to say that Dr. Pimentel will not have to deal with the petroleum crisis I, or my children will someday face. On the campus of Berkley, reality is rarely a consideration.
Quote:
Please provide more information on the analytical techniques used by the researchers. In the past, Dr Pimentel's studies have employed the following flaws:
- Using energy for plant construction, including the embodied energy in concrete and steel. No other energy sources have been subjected to such level of detail. For example, what is the embodied energy in the tankers used to transport oil, the pipelines, the military ships, planes and aircraft?
- Pimentel has consistently used very outdated plant data. In the 1990s, he was still using plant data from 1978! It's been some time since I perused his footnotes, but he certainly use data that reflects the current industry, not the industry in it's infancy nor farm-based plants.
- Does Pimentel allocate any energy value for co-products fro ethanol manufacture? Ethanol is just one of several products produced from the corn. If a portion of the corn product is used for non-energy products, then ethanol should only be "charged" with the energy for the portion of manufacture related to the ethanol.
Dr Pimentel's research has been reviewed and roundly rejected. Does he address the concerns and problems with his analysis raised by many researchers, including those at DOE and USDA? These questions deerve to be answered!
Quote:
I agree wholeheatedly with the statements suggesting that Pimental is using very outdated facts and figures in his calculations, plus taking liberties on items such as solar energy inclusion. Most ethanol plants operating today consume 38,000 - 42,000 BTU/gallon of anhydrous ethanol. The ethanol itself produces about 77,000 BTU when combusted. If you want an updated analysis by a very thorough group of technical economists, check into Dr. Hosein Shapouri, Chief Economist of the USDA in D.C. He counts everything, from crop planting, harvesting fertilizer, transportation to the grain elevators, and all of the production costs. He is quite thorough. His latest (2005 estimate based on 2002 farm yields) shows an 89% net energy gain when using ethanol.
OK, but its not all about BTU's. The primary role of ethanol in the fuel supply is to displace oxygenates and octane enhancers. Let's see...methyl tertiary butyl ether, Benzene, what else? None of them are anything you want a human of child-bearing age exposed to. Ethanol is pretty benign, compared to what it is replacing.
Then there is the food-for-fuel arguement. I don't have the precise number, but outside of making fuel and beverage alcohol and sweeteners and paper starches, probably 90% of the corn grown in North America goes to cattle feed. When ethanol is made from corn, the protein, fiber, and oil is returned to the food system as "distillers dried grains", a high protein feed.
Carbon dioxide? Ethanol is CO2 neutral, because the corn takes in as much CO2 as it produces when it burns. Where else does the carbon that makes up the starch come from?
Also, very few people look at the energy that it takes to produce gasoline. I have seen numbers suggesting that it costs from 30-40% more energy to pump, transport, refine, and transport crude oil to gasoline than is obtained through combustion. Shouldn't THAT be the baseline when looking at ethanol???
Someday we'll hear how Pimental is funded, or understand his motivation for periodically publishing misinformation. Until that time, we'll just have to try to educate people with more accurate information.

Also, note that ethanol and biodiesel represent net-zero C02 emissions. That is, the plants these are derived from have to remove CO2 from the atmosphere to make the fuel.
Its simple battery technology killed the electric car.
I think that what car companies really need to look at is Plug-in Hybrid cars. You get the best of both worlds.
Unfortunately, you have to plug in your car, resulting in high energy bills, and you get what? A couple minuites of driving?
I'm too young to drive, but we have a Lexus 400h hybrid. Okay, its a big SUV, but it only drives for a couple of minutites. I wonder how long a car like the Prius would last on batteries.

Would this be acceptable:
Acceleration 0 to 60 in about 4 seconds
Top Speed Over 130 mph
Range 250 miles EPA highway
Full Charge As short as 3.5 hours
Battery Life Useful battery life in excess of 100,000 miles
Does it look like a Prius? Well decide for yourself:
P.S Just a little question (for those who were around to use PDAs then or around period) try to recall what mobilephones or/and PDA's could do TEN YEARS AGO (which is what this film is about 10 year old technology!) and what they can perform today in the CHARGING vs USAGE time...I recall when you charged overnight (many of us still do but the devices dont need it) and you had maybe half a day of real usage, now you do the opposite charge a couple of hours and use it a full day...
Unfortunately, you have to plug in your car, resulting in high energy bills.
As you do yourself mention you are not driving yourself yet, so this explains a little but in all fairness your statement about 'resulting in high energy bills' is not very accurate. The all electric car calculates to about 1 PENNY / MILE try to do the math on ANY of the vehicle(s) you drive now, be it hybrid, diesel or gas! Do the comparision, I am glad you used the wording ENERGY BILL because your GAS BILL is also an ENERGY BILL :D
Yes, I see your point, but it does depend on the region. And I don't know about where you live, but here in New Jersey, gasoline doesn't go on your energy bill from the utility company :)
And that does look cool, but I must ask you several questions.
One, how do you know if that 1c/mile is for what energy company? For all you know, the person who said 1 c/mile could have solar panels on his roof! :)
Two, what happens if you drive more that the supposed 250 miles, and you are nowhere near home?
Three, how much would this cost?
Four, even if electric gas stations came to be, hmm.......... very nice........ you sit at the pump for 4 hrs. Excellent.
And don't you see something wrong here? The energy to drive such a car would be ENORMOUS. I would think that you would have to haul along a truckload's worth of battery.
If our Axim takes ~2 hrs to charge, you saying this thing can charge in 4? I know, different technology and stuff, but still, don't you see something wrong?
Edit> Upon closer inspection, this........... thing............ also uses Li-Ion batteries. So, I bring several questions. If you are so concerned about your Axim using up its charging cycles, would you not your car? And also, remember this: Its has been widely said on these boards taht the Axim's battery is already at highest efficency attainable. 4 hours............ twice Axim............. 2200 mah? Lets be nice, and say some, impossible, breakthrough technology occured, and give it............ 10 amps/hour. (For all people who cannot see the problem, that is, as of now, impossible). Anyway, a battery big enough to cart to give it 250 mile range would be illegal on my roads. I believe that would be will over 4 tons.

That's the beauty of the PIH (Plug-In Hybrid), you can use it from grid power for daily commuting without the need for external fuel, getting great economy, the equivalent of around 30 cents a gallon. But if you need the car for a longer trip, when the battery drains, the gas motor kicks in, and you can conveniently refill your tank from any normal gas station.
Yes, I see your point, but it does depend on the region. And I don't know about where you live, but here in New Jersey, gasoline doesn't go on your energy bill from the utility company :)
Energy is energy, gas aswell as electricity. Anything you pay can be called a bill, just as your actual piece of money can be called BILL. There seems to be some language barrier here?

Teslamotors site states this, if you have doubts please present your own calculations based on your local electricity costs.

Same thing that happens when you are 250miles from home and your AXIM goes dead :D

Most of your questions including the price is posted on the website please read the website if you have questions, I am not an employee of this company sorry.

May I ask you something? What kind of 'stations' do you visit to charge your Axim? Please think a bit here ok? Would you not charge your axim at home, work or/and school if needed/when possible? Yes. So in a similair fashion you would do with an electrical vehicle. In fact for instance in Scandinavia just about all public parkings and companies have outlet posts (one for each vehicle) why? Because people plug their vehicles in to warm up their engines and insides with electrical heaters on a timer prior to leaving for home. So in a similair fashion you would do that. Now obviously 4hours it to charge it full, now do you charge your Axim all the way full EVERY SINGLE time? Or do you let it go 100% empty each time before you re-charge it? Well life doesnt allow for that always. Same would apply for a vehcile like this

This is no drawing on the paper, this vehicle is available to purchase in the very near future, in fact just last week they started taking preorders! I have personally seen one of these in person, they are very near for the public! Do a little googleing and you'll see, the hybrid you have yourself (as you claim) it's batteries are not tiny either!

You really DID miss the point all together, but the fact that you say you are too young to drive (under 16 curently) explains why you missed the point....so lets try again!
This movie is talking about the electrical car(s) as of a DECADE ago (10 years back!) now as the film title states it was KILLED, so you could say that the development of the electrical car(s) was somewhat put on hold then, so what we are seeing now is not 'up to speed' what would our cellphones (mobilephones) and/or PDAs or Laptops for that matter look like if they would have all been put to the side in 1996, and along with that the battery industry wouldn't have had any interest in developing and producing batteries of that sort. Lets take a look:
Standard Battery Type Ni-Mh
Amperage 1200 mAh
Standby Time 96 hours
Talk Time 240 minutes
Nokia 9000 was introduced http://en.wikipedia.org/wiki/Nokia_9000
- 8 MB total
- 4 MB Operating System and applications
- 2 MB program execution
- 2 MB user data storage
- Processor: embedded INTEL 386 processor
- Operating System: GEOSTM 3.0
SO MY POINT BEING THE ELECTRICAL CAR INDUSTRY HAS BEEN FORCED TO A HALT FOR ABOUT A DECADE!
You might want to just educate yourself a little on this topic (as even for those of us who were driving in 1996 quite informative!) by seeing this movie, though there are poiltical parts of this movie it is quite informative and maked you wonder where would our cars be today if what happened in 1996 wouldn't have happened. Would we even have anything remotely close to the AXIMs if the same happened in the PDA world? As for the comment that the technology or battery performance has reached its limits perhaps people are talking about with current pricing, batteries and such it is pushing its limits but trust me within a year/2 years from now you will have pocketable computing at levels never seen before (as has been every year for that matter).
Also you can't compare the AXIM to the electrical car, your axim doesnt have a single moving part (by the means of electricity) unlike your laptop even, EVERYTHING your electrical car would be doing would have to be by the means of an electrical motor. My only reason for comparing was look at the rapid development of battery perfromance in one decade! And lets face it the auto industry IS larger than the PDA/Laptop one so IF it had continued to develop in 1996 until now 2006 it would have surpassed technology we see now in gadgets.
P.S. Yes the Dell Axim X51V is one of the best devices when it comes to battery time with built in WIFI thats one of the reasons I have one, and trust me been through all kinds of similair size devices including the $2000 OQO minicomputers but battery times just doesnt cut it on those!
Okay, One, you seemed to miss the point that some of those points, such as the energy bill, and going to a electric station, were NOT meant to be valid arguements.
Two, I'd like to point your attention to one of your "arguements" that seems to do nothing but STRENGTHEN my argument.
Quote:
the hybrid you have yourself (as you claim) it's batteries are not tiny either!
Thats the whole point!!!! Think. If the Lexus RX 400h's batteries aren't very small (as a matter of fact, they take up all under my backseat), and this thing can drive for, maybe, 5 minuites on electricity, on a highway, even less........ THIS THING IS CLAIMING TO BE A CONVERTABLE AND BE ABLE TO FIT A BATTERY THAT CAN DRIVE THAT THING 250 MILES!!!! See anything wrong wit the picture?
And third, contrary to what you say, there is no price listed :).
Fourth, you say that you don't have to charge it fully every time. You seem to miss my point there. I don't care how much you have to charge it. I am comparing the Axim's battery, 0%-100%, and that car's 0%-100%. Cmon, the Axim takes about 2 hrs, the car 4 hrs, they use the same technology, and the Axim's battery is so small?
I can't seem to find the hybrid system's booklet, but that engine's power usage wasn't very small.
Lastly, why can I not compare the Axim to the car? First, I'm not comparing the products, I'm comparing the BATTERIES (and charging time). Second, does it matter how many moving parts it has? If the Axim uses 500 ma, and the car uses........... 6000 ma (which is kinda low), can I not compare it?
And even if I can't compare it, how about I compare car vs. car? Lexus RX 400h, vs. that car? Notice something wrong about power requirements? Unless this company has developed cold nuclear fusion, and are telling us they are using Li-Ion batteries, then this would not work.
And Pocket Brain, I think that plug in hybrid's would be great. I can't wait till they start coming out with them.
And I am younger than 16 (actually, in New Jersey, its 17, but whatever), I am 13, but I did way more research and know way more about this stuff than my dad, who does drive. So, does it really matter if it comes from me or my dad? Would you trust a illiterate fool who is 40, or a 8th grader who is smart?

Quick history time. Early 1900's electric cars OUTSOLD gasoline cars. The superior power and range of gasoline cars put most of the companies out of business by the 1920's.
This EV1 which the movie is based on was not really a very good car at all. GM felt it would be cheaper to recall and destroy the cars then to continue to support them. GM and all the other car companies are out to make a profit if they do not think that they will be able to or make back the investment in a short period of time then they cut the program.
This wonderful EV1 took hours to recharge and had a short range. If you forgot to plug it in you were stuck. The website for the movie only says it would be far enough for an average daily drive but admits that a family would also need another car to do anything more then a short drive. What it is failing to say is that the EV1 had a range of 50 to 75 miles. So a brand new car would be able to visit locations around 25 miles away. I don't know about anyone else but that would NOT be good enough for me. Even worse batteries lose the ability to hold a charge over time. Newer technology how increased the life of batteries but the EV1 had lost HALF of its range within only 2 to 3 years. The batteries would have needed to be replaced by the latest at around 5 years old. The good news is cost of the batteries would have been only around $1,500 since the car used 26 lead acid batteries.
If you look at the history of industry it is VERY rare for true innovation to come from within. Normally it is an outside company that produces something that forces the older companies out of business or to change. I suspect the same is going to be true of electric cars and the future of the automovtive industry. Traditonal car companies do not want to "waste" their R&D budgets on technologys that they cannot prove will work or are wanted by the general public.
For examples look at communications. The internet was not a product of the telecommunications companies. The telephone did not come from the telegraph. There are plenty of other examples.
When the technology is there you will see someone step up put down his own money along with several other investors and you will see a company produce a new type of car. Just like how Ford changed the automotive industry all those years ago this new company will change it once. It WILL happen and I think that it is going to be soon.
In my mind the future is the electric car but its going to take years and a lot of changes to get there. First I think we are going to see more and better hybrids such as the custom mini that was produced a few months ago. It would require radical changes to the automotive and battery industrys. Would be out of reach for most individuals but would start a move towards a car which everyone can love.
If you want to see just how far the "HALTED" electric car industry has come look at this Mini. The car gets 80 MPG and can be run only off its charged batteries or uses a gasoline generator to charge the batteries if you do not want or are unable to plug it in. The car has a range of 200 - 250 MILES on a single charge plus with a full tank of gas and a full electric charge can go almost 1,000 miles before you need to fill it up again with gas.
Next take a look at Telsa motors. A modern all electric car company that just started taking orders for an electric roadster. The company plans to start producing standard road vehicles within a few years.
The electric car industry is alive and well and anyone who really wants an electric car CAN get one today if they are willing to pay for it. Who knows 20 years from now we might all be driving around all electric cars that you plug in at night and fill up with hydrogen to power a fuel cell on longer trips. The technology for that does exist today but until it can be mass produced and is affordable you will not see it except in limited production vehicles.
Okay, One, you seemed to miss the point that some of those points, such as the energy bill, and going to a electric station, were NOT meant to be valid arguements.
Two, I'd like to point your attention to one of your "arguements" that seems to do nothing but STRENGTHEN my argument.
1. Ok? Not sure what you are trying to say but simply put:
Electricity & Gas = ENERGY
Bill = any invoice or receipt you need to or already paid (be it from your local electric company or the local gas station, ask your dad he can explain)

By covertible I assume you are talking about it being a cabriolet or open air, and not sure how that would have anything to do with anything? You think a sporster is heavier or has more air drag than a small SUV such as the Lexus RX? :)
There is no claims in the Tesla facts, as stated this is an actual vehicle already in usage. Yes I do see something wrong with the picture, but its not related to the vehicles in this discussion.
And third, contrary to what you say, there is no price listed :).

Please do not confuse actual facts of life (reality of how something is being used) with what you should or would 'have to'
Axim and your Lexus what form of the technology is the same, please elaborate on that? How many electrical motors does your Axim have? Your Lexus has computing powers that are way beyond your axim for just about every task it does from feeding the individual cylinders to breaking to even the lighting on the vehicle, which gets us to the next topic, how many 55w bulbs does your axim have? What about your Lexus? :) Please do not compare oranges and apples (though apples are closer to oranges than your Axim is to your Lexus) You have completely missed the comparsion I originally intiated and that is of BATTERY DEVELOPMENT compare that to TEN YEARS ago to now, not sure how many battery powered devices you were using 10 years ago or 20 years ago for that matter since the electrical cars that were ON THE MARKET in 1996 were not developed in that YEAR. In fact if you go watch the movie you will see what a dramatic improvement they did on the batteries even during the EV1's short lifespan!

Your vehicle has TWO engines, where as power generated from one indirectly stores it for the other...

There is alot more to this equation than just amps, there is also effecieny take a light bulb of the incadecent type it produces only so much light and the rest goes to heat, the HID bulbs has alot better effecieny so does the LED light products, each with its plus and minus, the point being when you are talking about two different usage of the amps you can not compare them side by side, as mentioned already your Lexus has many many Dell Axim level of computing powers in it and it can hardly be measured how little impact they have on the overall battery time (meaning even if you were able to unhook all those it would not dramtically change the Lexus' battery time). Electrical motors have a completely different effecieny ratio than your PDA does, in fact this is the main reason a laptop with wifi cant last as long as your PDA, because not only does it have to power a larger display and backlighting but it also has a number of electrical motors for the harddrive, the fan(s) etc etc.

If you go and see the movie you might learn a little more about this world we live in, the fact is the MAIN obstacles are NOT the techinical ones, thats what the whole movie is about! It would be fully feasible to have the majority of vehicles on the road today to be without a combustion engine all together. Just go watch the movie you will learn alot!

They've been around for quite sometime, just not for the 'mainstream' because in a similair fashion as the service providers (Cingular, Tmobile, Verizon etc etc etc) live in symbiosis with the manufacturers of the devices and both have to gain from each other, this is why the hybrids have not been plugins uptill now, because you are 'forced' to 'charge' your part electrical vehicle with GAS not electricity, again go watch the movie!
And I am younger than 16 (actually, in New Jersey, its 17, but whatever), I am 13, but I did way more research and know way more about this stuff than my dad, who does drive. So, does it really matter if it comes from me or my dad? Would you trust a illiterate fool who is 40, or a 8th grader who is smart?
I rest my case, you have answered you're pwn question ;)
This EV1 which the movie is based on was not really a very good car at all. GM felt it would be cheaper to recall and destroy the cars then to continue to support them. GM and all the other car companies are out to make a profit if they do not think that they will be able to or make back the investment in a short period of time then they cut the program..
If you have seen the movie you will know the REAL reason for the EV and others mentioned in there hit the roads in the first place, it was legislation put in place by California State which was challenged and taken to court by the large auto companies INCLUDING the USA federal government (yes the Fed gov sued California along with the big auto giants), once they one that lawsuit all the companies, GM, Honda, Toyota and Ford pulled in all their cars that were never sold but only leased. The only one to give in to the pressure was Toyota why we can still see an occasional Toyota Rav4 EV on the roads
Btw the EV1 is the reason we still see Saturns today in plastic its a heritage from the EV era as the EV's were sold through the Saturn dealerships, you ever wonder why the lowest end GM product uses an odd and thereby more expensive body solution than any other GM product? Well there it is, the EV1 was plastic to save on weight, Saturn is now slowly but surely going away from the plastic bodies...
As for my comment about standstill on development, look at the charge time for the Tesla about 4hrs and the GM EV1 about 5-6hours, if we had the same little development for our gadgets we would still have to charge them around 8-10hours :( THAT is MY point, look at the size of the gadget's batteries compared to 10yrs ago and charge vs. standby & usage time. There is so many 'ends' you can improve the electrical vehicle's battery time on its almost endless even in today's technology. One example which the Prius has done "good" in is the HID and LED lighting it has alot of, it hardly has any old incadecent lighting solutions (which swallow alot of amps and produce alot of heat, read loss of energy!)
Uhh........ That was a general comment, meaning that, would you trust an adult who doesn't know anything, or a genius kid? Age may not be as important a factor as you think.
And where did you get that info?
(And my dad isn't illiterate)
This time, I don't have all the time in the world to answer all of my questions, since I have 3 tests......... so.......... but I will say this.
The Lexus RX400h has 3 motors. Two electric, one gas (Thats for the 4wd version, though) And about the 5 minuites, how about you look at the battery meter while driving, and thats even being charged as you drive, so maybe its not 5, but perhaps 10, but still, 10 miniuties isn't gonna get you 250 miles.
My point with the convertable, wasn't anything except for the size. Where are you gonna put a battery big enough?
What does the Axim and a car have in common? They both have batteries.
And you seemed to miss my point about #1. It was meant to be an idle joke, a side little talk.
And while I am not doubting that electric cars can happen, what I am doubting is that that car of Tesla's can drive 250 miles, among some other things about that car.
Oh, and although I reconize that electric motors are different from say....... Xscale processors, they are not so different as to cause a huge technological difference in terms of battery power/life/capacity/engine usage, whatever.
