An Albany-based company has created a program that encourages upstate
New York farmers to grow today’s biofuel du jour, a pesky weed known
as Thlaspi arvense but more commonly referred to as pennycress or
stinkweed. Despite the experiments your college roommate conducted in
his ’89 Subru Loyale, this is believed to be the first time a car has
been powered by a weed. We imagine that a certain stations.
What makes stinkweed different than the plethora of other world-
saving, game-changing biofuels that came before it (anyone remember ,
“I’ve been trying to get rid of these things for 30 years. Now you
want me to plant them?'”
Stinkweed can grow almost anywhere, it’s as tough as an old Volvo and
it has the potential for high per-acre yields. It’s that kind of
cockroach-like durability that makes stinkweed so attractive to
scientists searching for a stable, hardy source of fuel.
The folks at say stinkweed is an ideal biodiesel feedstock because its
seeds yield 36 percent oil when crushed. They should know: After all,
they work for Biodiesel Magazine. John Fox, president of Innovation
Fuels, says the company is testing the plant and its seeds and so far
things look good, even if they smell bad. “We’re really pleased with
the oil,” Fox said, adding that stinkweed oil has excellent cold-flow
properties.
It could be an exciting development for biodiesel, which has seen
production go through the roof alongside gas prices. Production has
climbed from 25 million gallons in 2004 to 500 million gallons last
year, according to the National Biodiesel Board.
Still, there’s one major hurdle before pennycress supplants (pun
intended) other biofuels: Although it grows like a weed, it isn’t
domesticated enough to be planted as a crop. Main photo by .
You say that growing this weed wont affect world food, but if this
becomes a popular fuel, then don’t you think farmers will grow this
instead of corn/soybeans?
It could be a viable replacement crop for tobacco farmers. RE: the
van: Why would someone paint a Mercedes logo on the side of a VW? Were
they high or just stupid? With hippies it could be either or both.
Skud: It would grow in the winter, allowing the spring/summer season
for soybeans and corn. joeg: it’s a peace sign, proving your hippie
point…
I R not a botanist but is it not a bad idea to promote the widespread
cultivation of invasive species? Or is this an invasive species by
virtue of being hard to kill? I’m not sure of the distinction.
I saw a bunch of articles on TreeHugger bout some Georgian guys trying
to make Kudzu a biofuel. On one hand it sounds great when you consider
that maybe people will go out and tear down existing kudzu for fuel
but, on the other hand, won’t people start growing it?
@Brian It’s not a peace sign…a peace sign has a center line that
dissects the circle from top to bottom and two half lines that run
from the center of the long line and connect to the side of the circle
at about 4 and 8 o’ clock. Who’s the hippie now?
The Nadir: I think the difference is that there is a huge demand for
fuel… I’m sure this isn’t the actual definition but a “weed” by
nature is something that’s totally unuseful and just stops other
things from growing. I do believe it’s no longer a bother when you’re
actually trying to grow the weed. Also, there’s cash incentive to grow
it so I’m sure it won’t just spread out of control or anything, they’d
want to harvest all of it.
Biofuels have a great future and bode a propitious prospect for
eliminating our dependence on, and addiction to, petroleum.
The industry is in its infancy, but is making great strides. Using
corn as a feedstock creates as many issues as it solves. But using
weeds like pennycress or kudzu holds great promise. New issues? Yes.
Manageble? Yes!
One day this feller from Washington come by And he spied us and he
turned white as a sheet And he dug and he burned And he burned and he
dug And he killed all our cute little weeds Then he drove away We just
smiled and waved Sittin’ there on that sack of seeds
Glad to hear it! Our current brand of agriculture is in trouble. We’ve
bred and culled the crops we eat, over the centuries, to the point
that their gene pool is virtually nil. Know what that means? Our crops
can’t adapt to changes worth shit.
Why are weeds so hardy compared to, say, corn? We do all we can to
eradicate them…but we’ve so far failed. The adage about “that which
doesn’t kill you” certainly applies to plants. All that survive are
the weeds that had mutated to fit the new agricide-heavy environment,
say. That means this stinkweed will be doing well, as global warming
slowly starts to bake more and more of our food crops. I don’t know
how we’ll cope with this problem as far as our edible plants go
(vertical farms anyone?), but…if we turn stinkweed into a viable
ethanol source, I’ll be feeling a lot more confident about it.
The problem with weeds is they grow uncontrolably when they are
thought of as a weed. But try to deliberately cultivate weeds and they
refuse to grow. . The question is not so much that one can get 36%
yield from the seed, but what is the yield of seeds per acre?
