Re: [Biofuel] shedding fat for oil
What about motorcycles? Is there any alternative fuel for motorcycles? I know they get great gas mileage (i get 40-60 mpg depending on how i'm riding and if i'm mostly on freeway or city streets), but i would rather be independent from fossil fuels. Unfortunately, due to the nature of my job, i am required to have a vehicle (a bicycle would be an easy alternative otherwise). dylan -- a href="" href="http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=86">http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=86img border=0 alt=Get Firefox! title=Get Firefox! src="" http://sfx-images.mozilla.org/affiliates/Buttons/125x50/takebacktheweb_125x50.png//aa href="" href="http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=181">http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=181img border=0 alt=Get Thunderbird! title=Get Thunderbird! src="" href="http://sfx-images.mozilla.org/affiliates/thunderbird/thunderbird_small.png">http://sfx-images.mozilla.org/affiliates/thunderbird/thunderbird_small.png//a ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
Re: [Biofuel] shedding fat for oil
It is a good point that losing weight and increasing fuel efficiency go hand in hand. It seems that the heart of the issue is consumption. Kind of obvious but it does make sense. d-- a href="" href="http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=86">http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=86img border=0 alt=Get Firefox! title=Get Firefox! src="" http://sfx-images.mozilla.org/affiliates/Buttons/125x50/takebacktheweb_125x50.png//aa href="" href="http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=181">http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=181img border=0 alt=Get Thunderbird! title=Get Thunderbird! src="" href="http://sfx-images.mozilla.org/affiliates/thunderbird/thunderbird_small.png">http://sfx-images.mozilla.org/affiliates/thunderbird/thunderbird_small.png//a ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/

I understand the the cars in the transcontinental mileage contests thatused to be held were specially modified with gear rations andtransmissions to accelerate from about 5 mph to about 15 mph, switch off, coast down to 5 mph and start and accelerate again. That way they got thedrag advantage of low speed plus the engine efficiency advantage ofoperating at high manifold pressure during acceleration (but not too high manifold pressure, avoiding rich mixture).Continuous opertion at a steady speed at high manifold pressure and lowspeed would involve such extreme overdrive (except maybe with acontinuously variable transmission) that it would be very hard to accelererate or handle even gentle hills, and the car would be very hardto drive.Car drag is a mixture of rolling resistance (power consumption variesdirectly as the square of the speed) and air drag (power consumption varies directly as the cube of the speed).I am *really* suprised that someone would get best mileage at 59 mphand I suspect something odd going on. It seems to me that the drag wouldbe just too high regardless of how the gearing was optimized.

I know the adage about55mph is from before the speed limit change; and it seems simple for the car manufacters to change the ratios to move the best ratios up toa 60 or 65mph area rather then 55mph.

Re: [Biofuel] shedding fat for oil
Forgive me... my comments were a little broad, but i was referring to those who cannot fit into fuel efficient vehicles because they are overweight (hence, shedding fat for oil), height is a different matter entirely (which i, actually, hadn't thought of until you brought it up...thank you), and for those who require more legroom: the station wagon is an excellent choice because they are long enough and have considerably better fuel efficiency than SUV's or vans (which seem to be the other alternatives for people who have long legs). I have had good experiences with the Subaru Outback station wagon (32 mpg on the freeway during a weeklong roadtrip). So, i am sorry if i have offended. I suppose the real goal is to be more fuel conscious and do whatever we are able to to improve fuel efficiency and rid ourselves of the reliance on petroleum fuels. dylan On 7/9/06, Kurt Nolte [EMAIL PROTECTED] wrote: Dylan wrote: Another advantage to this agenda is that americans would be able to drive more fuel efficient cars.Let's face it, the size of cars in the united states has increased with the size of people.Many americans can't fit into the more fuel efficient cars that are popular in other nations.So the savings would be double edged: lighter people and smaller more fuel efficient cars. Voila!(that's not even mentioning the money saved on healthcare for diseases related to obesity)My contention with this is that I have this problem, and it's notobesity that causes it. I cannot fit into a new Golf, an Insight, or anything of similar size, and it's certainly not because the seat's notwide enough (Usually I have plenty room to spare, actually).It's my legs. They're far too long to fit into most of theseultracompact or even compact cars, which are the highest efficiency ones. I usually end up with my knees where they hinder my ability toturn the steering wheel, which is uncomfortable to say the least anddangerous to say more. I'm not alone in this, either; half of mycoworkers are of a similar height and run into similar problems. (We're all at least two inches over six feet tall, and mostly leg to a man).Thus, actually, legroom was a huge factor when I went looking for areplacement car. The car I drive now gets terrible mileage by most elite standards (A mere 28mpg combined), but it is after all only ayear younger than I (it's twenty) and weighs in at 3000 pounds. It'salso a station wagon, and it's long wheelbase gives me plenty of legroom for comfort and safety.So beware, please, sweeping statements like that; they aren't always true.-Kurt___Biofuel mailing list Biofuel@sustainablelists.orghttp://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.orgBiofuel at Journey to Forever: http://journeytoforever.org/biofuel.htmlSearch the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/-- a href="" href="http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=86">http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=86img border=0 alt=Get Firefox! title=Get Firefox! src="" http://sfx-images.mozilla.org/affiliates/Buttons/125x50/takebacktheweb_125x50.png//aa href="" href="http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=181">http://www.spreadfirefox.com/?q=affiliatesamp;id=0amp;t=181img border=0 alt=Get Thunderbird! title=Get Thunderbird! src="" href="http://sfx-images.mozilla.org/affiliates/thunderbird/thunderbird_small.png">http://sfx-images.mozilla.org/affiliates/thunderbird/thunderbird_small.png//a ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
