This is the very first instance of a working corn stover harvester I have seen, I am gratified that the work has progressed this far, even though as the researchers say, more needs to be done. I am surprised John Deere is only supporting the project to the tune of $50,000. It stands to make millions on the equipment if and when it is perfected.


The Corn stover collection project (site webserver appears to be down) managed this quite a few years ago, but did a separate collecting pass.  It would be best to have a machine to make high-density bales in the same pass as the grain harvest.

Now if we can get out from under the ethanol lobby and use our biomass to make a fuel we can just pour in our current, unmodified cars and GO (Butanol! www.butanol.com) we'll be getting somewhere.

Oh, did I mention there's no special handling needed with butanol - You can use the existing storage and pipeline infrastructure? I guess I just did.


That won't get us where we need to go; there isn't enough biomass to replace gasoline with butanol any more than ethanol.  The job will require replacement of the transport energy system from the production end to just short of the wheels.


We agree on that poet. Fuel farming powering internal combustion engines just won't do it. It's physically impossible to produce even 10% of present fuel use from fuel farming. Not enough land.

But if we reduce fuel use to 10% of present levels with plugin serial hybrid powered transportation.

Then biodiesel from solar collector grown algae will provide that greatly reduced amount of liquid fuel.

Oil, coal, and tar sands can be turned into natural gas underground with no mining or refining to provide backup fuel for hundreds of years.

Main baseload power from wind and water power, solar power, and distributed backup storage and generation using fuel cells running on biogas or that natural gas backup source.

It's all doable right now. And much cheaper than the present system. 75 cents per "gallon" to run your electric car. Free heat and electricity for those with solar homes. Revenue from the power company for consumers who plugin their vehicles to act as generation and storage capacity for the grid.

Where does the extra money consumers save/earn go? Right back into the economy. Renewable energy. A huge growth engine.


The idea that you can harvest all that biomass with only the minimum fodder for the soil organisms rests on the fact that chemical farming has killed the main soil organisms already, so that the stuff being grown has no value to living beings except to burn it to drive the combine that harvests it.

Most of the people driving around now aren't going anywhere useful anyway, so it should be no great stretch to cut fuel use by 90% in the near future. When you subtract all the jobs where people are driving to work so they can afford to drive to work, and simply get them to stay home...well....


Acccording to KMW-Energy in Canada, worldwide biomass is the 4th largest energy resource after coal, oil and natural gas.
According to 2. Keith Collins (Chief Economist, USDA), “U.S. Agriculture and the Emerging Bioeconomy” presentation at “Advancing Renewable Energy: An American Rural Renaissance,” sponsored by USDA and DOE, America’s Center in St. Louis, Missouri, October 10-12, 2006 -- the US is planting 90 million acres of corn in 2007, maybe harvest 125-145 bu/acre, and an equal weight of stover. If we were to convert the stover to a liquid fuel (e.g. ethanol or pentane) at only 35%, we could generate 27 billion gal of fuel, from corn stover alone. Add to that biomass waste (??) from all other agri harvests (3x more?) plus forestry wastes (2x more?) and we would generate 6x27-162 billion gal/y of fuel, which is comparable to the 141 billion gal/y now consumed in the US.
I was delighted to read about Iowa State's dual harvester -- more power to that group!

The researchers ran their latest version of a stover harvester through about 50 acres of corn near Ames this fall. The harvester dumps a crop of corn kernels into the combine's hopper and blows a crop of stalks, cobs and leaves into a trailing wagon.
