Bear Kaufmann, Jeff Tiedeken and Jim Mason are at University of Minnesota, Morris this week installing the Powertainer and setting it up for its initial runs onsite. This has been a long haul, and we’re very happy to finally have it here and soon begin pumping biomass power back into the grid. A big thank you goes to Lowell Rasmussen, Jim Barbour and Dave Aronson at the UMM for making this project possible, as well as their general dedication to proving small scale biomass energy for midwestern ag applications. As well a huge thank you to APL team member Nick Monahan for taking on the complexity of managing the overall construction project and CAD sheet metal origami that rendered it to real.
There is a formal opening and demonstration onsite this Thursday from 1-3pm. It is open to the public so if you are in the area, you are welcome to attend. More information on the opening and the project can be found in the press release here: http://www.power-eng.com/news/2012/06/23/university-of-minnesota-morris-demonstrates-new-power-technology.html
For the next 6 months we’ll be learning and refining the installation onsite, and hopefully ending with a daily running installation. There are many details [...]
Yoav and I just returned from a trip to Indonesia to help with the set up and operational instruction for 2 Power Pallets there.
They are being integrated into a pilot stage “Village Hub” project. This pilot is located next to a palm sugar factory run by the Masarang Foundation (http://www.masarang.nl/). The factory uses waste geothermal heat from a 35 MW geothermal plant to dry and prepare palm sugar. This sugar is prepared from the sap of the Arenga Palm (http://en.wikipedia.org/wiki/Arenga_pinnata), a species studied by Willie Smits who studied forestry in the Netherlands (and gave a great TED talk (http://www.ted.com/talks/willie_smits_restores_a_rainforest.html). The sap is collected by bruising the fruiting branches, which release the sap, up to 100 liters per tree per day. It can be processed into sugar and ethanol. The Arenga palm can grow on poor soils, allowing deforested areas to be reforested, acting as a nurse tree to re-introduce more diverse species (see Willie’s TED talk above).
The Village Hub concept is to create smaller scale plants that can operate with zero external inputs and zero waste. These would collect sap from a collection of local farmers allowing economic opportunities to stay and protect reforested areas. The Hub would [...]
Gasification PowerExchange Workshop #6: GEK Building and 10kw Genset Configuration
Gasification Lecture and Demo: Friday, October 23, 7:30-9:30PM Building and Testing: Saturday and Sundday, October 24-25, 11am – 7pm Location: ALL Power Labs, 1010 Murray Street. Berkeley, CA Contact: jim ^at^ allpowerlabs.org Cost: FREEMore Info: http://www.gekgasifier.com
ALL Power Labs is starting a quarterly series of free gasifier workshop weekends to help bring more people to successful operation of small scale gasifiers. These workshops are open to GEK user/owners, as well as anyone with any other type of gasifier- or just a budding interest in the whole thing. If you have a GEK and want personal instruction in how to run it, or you want to build a GEK with oversight from the mothership, this workshop will be a great opportunity to do either.
The workshop begins with an evening talk and discussion on the science of gasification and a survey of its design and production history. Both beginning and expert reactor assemblies will be presented, with pointers to further reading and current issues and opportunities in the field. Everyone will get a packet with lots of explanatory graphics and core data charts relating to gasification. As you know, we’ve [...]
I’m trying to figure out how to better explain the basics of gasification. This is hard, as many of you know. So I’m trying to relate it to things that are generally known about combustion, then complicating matters from there. I’m trying to figure out the layers to take the newbie through- from most simple, to, well, does it ever end . . . ?
Here’s where I’m at currently: http://www.gekgasifier.com/gasification-basics/how-it-works/
How does this work for people? Anyone have suggestions for making it better?
As most of the mysteries of the universe are somewhere contained in the wider problem/opportunity of gasification, I can’t start at its many ends. But where’s the beginning before the freefall into the bottomless rabbit hole looking glass of biomass thermal conversion?
We’re discussing this explanation of gasification over in the forum here: http://www.gekgasifier.com/forums/showthread.php?t=162 . Give us your input.
Happy partial combusting to you on this Labor Day weekend.
Bear Kaufmann finished another run on the GEK test and datalogging rig and posted the results here: http://gekgasifier.pbworks.com/Instrumented-Walnut-Shell-Run-082409. This wiki page has a large collection of graphs and other data assemblies from the run. Bear is very clever. Someday he’ll get a Phd in all this. In the interim, we get to ponder his bi-weekly posting of dissertation worthy test runs and data visualizations. Thank you Bear.
The main issue he was/is trying to resolve in this test is how to measure tar. The usual “simplified tar testing method” with the greyscale seems very open to mixing the tar and soot signal on the filter paper. both tar and soot are “black”. Filtering before the sample tends to reduce both of them indiscriminately. So we’re trying instead to take the sample without any prefiltering, and dissolve the tar out of the sample with a solvent, and then measure the color/hue/greyscale of the liquid.
Does anyone here have any experience with this type of soluble tar testing method? Or otherwise have any input on the accuracy or import of the attempted tar-soot separation method?
In the pix above, and in the more detailed report linked above, you will see that [...]
Put a gasifier in your Baja beach cabana. Or in your back-to-school backpack. Yes, it’s the first ever (and maybe annual) APL “End of Summer / Back to School 10% Off Sale” on all things Biomass Thermal Conversion.
The rules are simple. Buy anything between now and the end of August and take 10% off our already too low purchase prices (shipping stays the same). This can be just a cyclone kit, or an assembled Level IV GEK, or a full Tower of Total Thermal Integration solution. Or, just a GCU. Well, it can be the new “Biochar Experimenter’s Kit” too. It just has to be a new order, not one already in progress, or currently waiting in the production and shipping queue.
So if you have been hovering around a decision for a bit, the next 4 days are a good time to bring your deliberations to fruition. Go to the usual GEK purchase page (http://www.gekgasifier.com/purchase/), assemble your combination of needs and desires, and take 10% off the tally when you get to the paypal screen.
While you are considering this possibility, here is a very interesting image of a running GEK taken with a thermal imaging camera at [...]
Hi everyone, It’s been another exciting, breakthrough week at All Power Labs and we wanted to make sure you’ve heard the latest:
1-APL unveils new, low cost “BEK” or Biochar Experimenter’s Kit” at International Biochar Conference in Boulder, CO. Jim Mason and Jay Hasty are in Boulder, showing off the TOTTI architecture, and more importantly unveiling APL’s new, low cost design for a Biochar Experimenters Kit, aka the BEK, naturally.
The BEK is completely compatible with the standard GEK cowling. It supports multiple pyrolysis modes in direct combustion, indirectly heated retorts, and hot gas recycle through bed architectures. Temperature, residence time, pyrolysis modes are fully controllable for characterized Biochar making.
The entire unit with everything shown below will be available to ship in October for $4395. We’re now accepting orders ( several were placed at the show ), and a deposit of 50% will hold your place in the queue.
Here’s a draft image, much more soon on our site and forums. This image and all content on it protected by Creative Commons/Copy Left.
