--Neat site; thanks for the link! FWIW one of the great things about
the Tote Goat is the box-section frame, which provides a *lot* of real
estate for engine hacking. A friend of mine runs a steam power plant in his
as it's got room on board for Propane fuel, flash boiler and a honkin' big
water tank. Not sure what the range is, but it's decidedly low tech and has
a real third world flavor, heh.

Biodiesel is just replacing one type of emission with another - and it
takes a lot of power to harvest/process the stuff. For these types of
purposes, there is an ancient form of power, called human power.
Imagine having a utility bicycle/tricycle on board with appropriate
gearing. ALthough maybe in certain situations probably a bit slower,
it is probably overall faster with no tuning, centrifugal clutches to
maintain, fueling, finding fuel - someone mentioned cruising in far off
places needing to go get batteries. Are you carrying a large tank of
biodiesel on your intercontinental cruises? I reckon a good utility
bicycle would be lighter, easier to stow on board, cleaner, cheaper,
less time consuming, and 98% as useful. Sounds like a good tradeoff to
me.

No it doesn't.

Wrong

"Civilization" can be defined as seeking to avoid any form
of physical exertion, whatever, no matter how productive or
healthy.

Civilisation is defined as living in cities actually.

Only Americans need personal vehicles at all times to avoid using their legs.

One square mile is 640 acres.
One square mile is 5280 feet by 5280 feet.
A tractor pulling a 30 foot wide disc plow will requi

5280/30 = 176 passes. That's 176 linear miles to plow the entire 640
acres.

Now the next question is, how much horsepower (fuel consumed) to cover
the 176 miles?

And then there are the herbicide/pesticide/fertilizer/harvest passes also.

Take it away Nick.

300 gallons biodiesel produced per acre.
300 time 640 = 19200 gallons.

Tractor pulling 30' disc plow get @ 4 miles peer gallon
4 times 176 = 704 gallons

19200 over 704 = 27.3
or
704 over 19200 = 4%

19200 over 704 = 27.3
or
704 over 19200 = 4%

Worst case (the disk plowing will have the highest power requirement)
is 5 times over the field or 5 times 704 gallons = 3520 gallons
or 18%. Should do much better though.

Per BP annual energy report:

Million barrels per day:
Gasolines 9.436
Middle distillates 6.087
Fuel oil .795
Others 4.199
Total USA 20.517
http://www.bp.com/productlanding.do?...tentId=7017990


9.436 million barrels times 42 gallons / barrel divided by (19200-704)
gallons yield per square mile = approximately 21,427 square miles to
meet our transportation demand.

Have you got a link to support that 300 gallons per acre?

The following numbers are gallons per acre.

macadamia nuts 240
brazil nuts 255
avocado 282
coconut 287
oil palm 635
http://journeytoforever.org/biodiesel_yield.html

The oil palm tree is a tropical plant which commonly grows in warm
climates at altitudes of less than 1,600 feet above sea level. There
is one species, the Noli or Elaeis oleifera (H.B.K) Cortes which is
native of America; another species is Elaeis guineensis Jacq. which
originates from the Gulf of Guinea in West Africa (hence its
scientific name) and better known as the African oil palm.
http://www.fedepalma.org/oil_palm.htm

Palm Oil, an ingredient found in many everyday products, is
contributing to the rapid destruction of rainforests. Orangutan
habitat in Sumatra and Borneo is being clear-felled at an alarming
rate for conversion to oil palm plantations. The orangutan, perilously
close to extinction, is suffering profoundly as a result.

Hi Dale:
This site claims 2641 gallons per hector:
http://www.oilgae.com/algae/oil/yield/yield.html

Gallons of Oil per Acre per Year

Corn . . . . . . . 18

Soybeans . . . .48

Safflower. . . . . 83

Sunflower . . . 102

Rapeseed. . . 127

Oil Palm . . . . 635

Micro Algae . .5000-15000:
http://peswiki.com/index.php/Directo...from_Algae_Oil
The highest yield feedstock for biodiesel is hydroponic algae, which can
produce 250 times the amount per acre as soybeans.
http://en.wikipedia.org/wiki/Biodiesel

Micro algaes present the best option for producing Bio Fuel such as
biodiesel in quantities sufficient to completely replace petroleum. While
traditional crops have yields of around 50-150 gallons of biodiesel per acre
per year, algaes can yield 5,000-20,000 gallons per acre per year.
http://www.solaroof.org/wiki/SolaRoof/MassAlgaeCulture

a.. Different algae species produce different amounts of oil. Some algae (
diatoms for instance) produce up to 50% oil by weight.
http://www.castoroil.in/reference/pl...sel_algae.html

a.. Soybean: 40 to 50 US gal/acre (40 to 50 m³/km²)
b.. Rapeseed: 110 to 145 US gal/acre (100 to 140 m³/km²)
c.. Mustard: 140 US gal/acre (130 m³/km²)
d.. Jatropha: 175 US gal/acre (160 m³/km²)
e.. Palm oil: 650 US gal/acre (610 m³/km²) [2]
f.. Algae: 10,000 to 20,000 US gal/acre (10,000 to 20,000 m³/km²)
http://www.biodieseltechnologiesindi...elsources.html

These are just a few sites, and I'm sure there are some more detailed sites
out there.
