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.

a.. Different algae species produce different amounts of oil. Some algae (
diatoms for instance) produce up to 50% oil by weight.

a.. Soybean: 40 to 50 US gal/acre (40 to 50 m³/km²)

c.. Mustard: 140 US gal/acre (130 m³/km²)

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

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.

Thank you. The links give me something to read...

And a little more hope in Peak Oil.

Foist, the question might be "how many horsepower-HOURS" of energy?"

And how much force times 176 miles?

Nick


Yes. That is the question required for a starting point...

And I dunno the answer.

I do know that the bigger tractors have 450+ horses available. We need a
farmer to give us (more like you ) some actual fuel consumption
figures.

I saw a show on discovery channel about the worlds largest tractors.IIRC
they used about 1 gallon per acre for one pass plowing.

It's easy to get some ballpark estimates. If you assume a tractor
speed of 6 mph it will take about 30 hours to do a square mile. At
200 average horsepower that will require about 300 gallons of diesel.

Not an easy or fun change. I didn't see the space to carry around the gear

This scooter is useless on most boats, anyway, as there's no place to STORE
it and if you left it on deck it would either end up a pile of solid rust
from the seawater spray or, due to its mass thrashing around, destroy the
boat and rigging on its way over the side, probably taking the handrails
with it.

Not many on the boat newsgroup have a 160' motoryacht with toy storage
garage in the stern....

Did you catch the width of the plow. Makes a little difference.

30' wide is approx.:
176/640 = .275 miles per acre.

Where 176 is the number of passes (1 mile each) with a 30' wide plow
to cover 640 acres (1 mi. sq.).

1 gallon per acre equals 1 gallon per .275 miles.
1/.275 = 3.64 gallons per mile (not miles per gallon).

Now I'll post this and then likely find somebody beat me to the punch.

If I have to get punched to the beat, could we have a waltz?

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.

Snip....

Yes, it does replace one emmission with another, but it is at least
a closed carbon cycle. You take up carbon when you grow the
crop (and my prefered crop is alge, which will double in 24 to
48 hours) and relese it when burned in combustion.
Human power is great, but not for everything, just as the
diesel bike is not good for everything, but fills a nitch that
could be useful to some.

Okay - fair enough - biodiesel and powered equipment has its uses. My
point was that, although crossposted to many groups, the initial point
was a biodiesel motorbike onboard a cruising sailboat, which I think is
impractical, un-neseccary, and better tools exist to do that particular
job, ie human power. Biodiesel is a good replacement for fossil fuel,
but it does have environmental costs.

Using human power also keeps you fit ! Since this bike seems to be targeted at
the USA, I reckon its another ploy to increase the number of 400 lb ppl !

On my canal trips btw I've lost quite a bit of weight from running around,
working locks and the like and it feels great.
