- Picer, on 03/27/2008, -1/+13Biodiesels are bad in terms of emissions and because they drive up world food prices. :(
- utdrew182, on 03/27/2008, -2/+14It's like they got to 8 and then decided it was time to head to the bar.
- borez, on 03/27/2008, -5/+17Please... Biodiesel = Bollocksdiesel
It take approx 15.33 acres of soya bean crop to run 1 car /year on Biodiesel. Please somebody tell me where the ***** we're gonna grow all these crops.
Besides it makes your car smell like you've been cooking french fries on the bloody engine block.
It's not a solution to any problem... unless of course you want the world to have a soya bean infested, french fry smelling future? - guinnessstout, on 03/27/2008, -0/+7Corn and soy are horrible sources for biofuel. It seems no one has heard of biodiesel from algae.

Source: http://www.oilgae.com/algae/oil/yield/yield.html - nekochan, on 03/27/2008, -0/+7also, biodiesel, especially that french fry-smelling kind, can be made of used cooking oil. the soy/canola/whatever was already used for food, and will be dumped if not put into a car or something.
and also, which would you rather have? chokingly acrid smog, or a nice potato-y smell? - Beanbones, on 03/27/2008, -1/+8You know what else you could use biodiesel (or rather, biodiesel acreage) for? GROWING [splendid] CROPS, YOU [nice gentlemen]!
- inactive, on 03/27/2008, -2/+7This is retarded. Until we start making biodiesel out of Algae it a WASTE.
15 acres to run one car per year on biodiesel? How many crops and forest do we have to clear for all the ***** cars?
Biodiesel is NOT environmentally friendly. Its worse than oil.
Better stick to solar. - Beanbones, on 03/27/2008, -2/+7Just for the heck of it, let's do some math.
Total number of cars in America (as of 2003) = 231 million
Total arable landmass on earth (in acres) = 7.66 billion
Acres needed to fuel one car for one year = 15.33
15.33 * 231m = 3.5 billion
3.5 / 7.66 = 45%
In other words, to fuel the cars in America alone, we'd have to devote almost half the earth's arable landmass exclusively to biofuel crops. Either my numbers are really, really far off, or the people promoting biofuels are full of [great ideas]. - borez, on 03/27/2008, -2/+6I didn't say that...all I'm saying is Biodiesel ain't the future it's cracked up to be.
- Beanbones, on 03/27/2008, -0/+4Or we could, I dunno, invest all that money in making fossil fuel engines more efficient? Make nuclear power plants safer and more efficient? Develop technologies that allow us to harvest hydrogen-3 from the moon as a fuel for clean fusion reactors? In terms of resource efficiency, biofuels are seriously lacking.
- klco, on 03/27/2008, -0/+3I think something a lot of people miss is that this isn't THE solution. Its, at best, a temporary fix, or an improvement. Just because we couldn't 100% replace our oil consumption with bio-diesel doesn't mean we should abandon the technology.
- vwvan, on 03/27/2008, -0/+3can we bathe in it?
- rswelling, on 03/27/2008, -0/+3As long as we keep eating huge amounts of french fries we have a good source of oil to make some biodiesel right? There are other ways to create Biodiesel besides soy crops, so why is it not worth investigating as an alternative fuel? Even if some people don't decide to use it, it's good that some of us do. Choose whatever alternative method works for you, there can be more than one solution to the obvious problem at hand.
- spunkmyer, on 03/27/2008, -0/+3I have been following the biodiesel story for a while now. While I agree creating biodiesel from soy beans and other type of crops is not the best use of resources but creating biodiesel from oil producing algae does. Lots of interesting reading out in the net for those interested in finding out about while algae strains make the best oil producers. I look forward to the day one can have a small algae breeding reactor on your property creating oil for a biodiesel conversion.
- borez, on 03/27/2008, -1/+4Fine, I'll recycle my cooking oil, it should get me to the end of the driveway after a couple of months or so.
- SwedishNinja, on 03/27/2008, -0/+2Then please move from Iowa to Minnesota and buy a car that can run on E85 if you're so concerned. Almost every station in Minnesota has an E85 pump. Sure, it's cheaper and better for the environment in the short term, but biofuels actually decrease your fuel economy to such a degree that these positive effects are negated. Also, as jjmelch said, biofuels wreak havoc on global food supplies.
Also: The Hawkeyes suck. :D - dizilbdog, on 03/27/2008, -2/+4I wish America would sell more diesel cars, That would make bio diesel take off even more.
- inactive, on 03/27/2008, -0/+2"Get off you oil-horse and think."
You sir, are an idiot.
There are more alternatives to oil. Wind, solar, algae biodiesel. And these don't rape our planet as much. - nekochan, on 03/27/2008, -0/+2if lake algae can be used, it would be great. people around here are too dumb/shallow to stop dumping fertilizer on their lawns. it all runs off into the lake, causing a massive algae bloom, choking everything, killing fish, making the water stink, and making it impossible to swim.
take our algae, please. - inactive, on 03/27/2008, -0/+2There are already chemicals to do that. Much cheaper too.
- louiebaur, on 03/27/2008, -3/+5Removing Paint and Adhesives sounds like a use full application
- inactive, on 03/27/2008, -0/+2@ guiness
Dude. I said biodiesel from algae. Even the website you gave me confirms its better than other options like Corn, Soya, Hemp.. etc.
Right now it is not environmentally friendly at all.

- nekochan, on 03/27/2008, -0/+2just stop by mcdonalds or something. they let biodiesel car owners take their waste oil free.
- borez, on 03/27/2008, -0/+2Algae supports the major ecosystems of marine life. We start scooping that ***** up in large amounts to power our engines and we really are gonna be *****!
- serif69, on 03/27/2008, -1/+3#16: The Spanish Inquisition.
- ferrite, on 03/27/2008, -0/+1As if Americans weren't getting fat enough, now I have to go through rush-hour with the munchies.
- konspence, on 04/05/2008, -0/+1We do not have the existing equipment to run solar/wind/geothermal in our cars. There are tons of diesels, which biodiesel can run in. Your argument is logical for a better world where electrical cars are dominant. But for now, you're comparing apples to oranges. It's not a choice of biodiesel OR wind. They have completely different uses.
- Rhodamine, on 03/28/2008, -0/+1Sorry. That link looks like it got truncated. Here it is again.
www.odu.edu/ao/news/highlights.php?todo=details&id=9365 - guinnessstout, on 03/27/2008, -1/+2Algae.
http://www.oilgae.com/algae/oil/yield/yield.html - Rhodamine, on 03/28/2008, -0/+1These folks at ODU have made some serious advances in the oil extraction process.
http://www.odu.edu/ao/news/highlights.php?todo=det ...
As a person who personally made some advancements in microalgal culture, I can say with a good deal of confidence that we can mas produce the algae. We won't be solving a fuel crisis this way. But the technology can seriously contribute to management of the issue. We can take advantage of favorable nutrient sources by affixing the growth facilites to use CO2 from coal smokestacks and/or nutrients from sewage treatment plants. Several birds with one stone. - ieure, on 03/27/2008, -2/+3Unfortunately, the knuckle-draggers over here refuse to drive fuel-efficient cars, like turbo diesels with manual transmissions.
- givemereplay, on 03/27/2008, -1/+2Biodiesel drives the price of grains and veggies through the roof because it is more profitable for farmers to grow soy or corn for energy rather than for food. We will all pay at the supermarket, and it doesn't even save gas. Biodiesel is a sham.
- bag2p, on 03/27/2008, -0/+1these alternative uses are pointless and irrelevant.
- warriorscot, on 03/27/2008, -0/+1Actually with the price of diesel these days its not actually all that great to get a diesel at the moment, and you swap one type of emmision for another as diesels are more fuel effecient but are heavier on the pollution, petrol isn't so bad as it does have fewer particulates in the exhaust. Its not the lack of diesels its just the size of the engines anything over 2 litres is a little excessive for any motor vehicle unless it is very big.
- smenzel, on 03/28/2008, -0/+1Now if only we could start producing biodiesel out of something that generates a higher yield AND get it down to an affordable price.
- postaldave, on 03/27/2008, -1/+2he he, he said "lubricity".....giggle.....
- JackStowe, on 03/27/2008, -5/+6This is great!
- nitrojunky24, on 03/27/2008, -0/+1big like a lot of American SUV's they'd be perfect fit for diesel really would. I wish our dodge ram 1500 came with a diesel because with a gas engine it does 12 MPG's (thats American gallons smaller then British gal)
- dizilbdog, on 03/27/2008, -0/+1Yeah that is true, but I think towns could start there own bio-diesel shops I mean you can have all the restaraunts in town donating there oil or give them a tax break bring it to the facility and then sell the fuel.
- Gerz1219, on 03/27/2008, -0/+1Is ignorance bliss? You make it seem like it hurts.
- orangetiki, on 03/27/2008, -0/+1Right because creating fuel from leftover cooking oils, rotting fruits and veggies, rubber products such as used tires, and the like do starve kids. What else would the kids pick at while they walk around the dumps? bio-diesel isn't just about creating oil from fresh corn.
- orangetiki, on 03/27/2008, -0/+1Screen print ink remover?? PLEASE!! I can't stand the smell of that 440 Screen opener. That sheet make you hiiiiiii! ( in a high pitch voice)
- orangetiki, on 03/27/2008, -0/+1that was my first car. Old beat up benz with 400,000 miles on it I got for 6k.
- guinnessstout, on 03/27/2008, -1/+2Yes your numbers are wrong.
10 000 liters = 2 641.72052 US gallons
On average a US drive drives 11000 miles per year. Lets say our car gets 25mpg.
That's 440 gals per year. Some strains of algae have been found to produce well over 10k liters per acre (google is your friend).
So at the average rate 1 acre of algae would feed 6 cars for a year. Also it does not take a year to produce algae. Corn takes anywhere from 50 to 90 days to harvest. Corn = bad biofuel. Get your facts stright. You can't lump 20 types of fuel into one catagory and say all biofuel is the same.
Additionally biofuel is ONE part of the massive solution for alternative energy. Everyone saying it is not a fix is correct, there is no ONE magical fix. You have to change the whole system. - triskele, on 03/27/2008, -0/+1Dugg for the guy in the thumbnail still driving his International Scout II from one of the few years they were running with a diesel option.
- guinnessstout, on 03/27/2008, -0/+1You don't harvest algae from the wild, it's produce in a farm.
- knobtwiddler, on 03/27/2008, -0/+1unfortunately if this catches on, we're not going to be making it out of used french fry oil. its going to be directly produced in place of farmed food products like ethanol... unless maybe they improve one of these algae techniques.
at any rate... solar/wind/geothermal electric power is better... or using those technologies to generate hydrogen is ideal for combustion engines, if you ask me.. or electric browns gas generators that electrolyze water into HHO gas.. there are many viable technologies that do not involve burning hydrocarbons. we have to get away from all hydrocarbon fuels. - guinnessstout, on 03/27/2008, -0/+1Honda Accord CDI gets upwards of 54mpg, sold right now in Europe.
- raintheory, on 03/27/2008, -0/+1Nice even 10000?
Odd, don't you think? -
