    And I would like to see chestnut forests revived.

    Do you have any opinion on the use of biochar for soil remediation?  I know little about the subject, but it sounds like a potentially good use for your program.

    Also, I don't understand your argument about the benefits of batch processing.  Usually, in materials processing, we like to set things up on a continuous basis when possible.

    But great article, I really liked it.

      ... opportunities to automate the process when you set it up on a continuous basis, but the focus here is on the politics, and having the biocoal production as close as possible to the production of the feedstock is a strong political benefit.

      One economic offset to the benefits of continuous processing in large scale facilities is that pushing processing out closer to the production of the feedstock shortens the transport of the harder to transport and harder to store coppice wood, where it can be easily stored, and easily transported to somewhere else that it can be easily stored.

      The other economic benefit is that continuous processing implies continuous production of the exhaust gas, which implies continues co-generation of electricity. Timing production of biocoal with this process so that the co-generated electricity is more valuable implies not using the equipment on an ongoing basis, and the batch processing approach promises a lower capital cost, which is better suited to intermittent use as opposed to continuous use.
