20s on the Floor – Gasification workshop dates for Belgium and US, Feb 2012 – Lots of new GEKs

 

20kw Power Pallets on the floor

20 kW Power Pallets on the Floor!

The shop floor at APL continues to fill with more good stuff. Here’s the scene from a couple weeks ago as we were finishing a round of 20kw Power Pallets. The 4 pictured units were later shipped to Indonesia, Italy, Mexico and Brazil. We’re blessed with interesting projects at nearly all of our end user sites, and usually some lucky APL engineer gets to fly out and meet the machine and people on the other end.

About half of the current Power Pallet shipments have a follow up trip to the user’s site. Many of the power pallets are going to demonstration or testing sites where someone wants to explore a larger deployment, and or set up a high value use that will likely lead to more good things. We’re excited when people approach us with interesting projects like this, and we try to make a trip to their site to ensure a successful start.

Some of these lead to workshops around the delivered machine, and proposed project. If you would like to hold such an event and/or exploration at your site, you are encouraged to contact us and propose a plan. We are usually enthusiastic, and all too often we say “yes”.

Global Workshops in February, 2012

Belgium (near Ghent): Feb 17-19, 2012

Tom Vandeputte of Green Power Solution and APL have finally set the date for a large multi-day workshop in Belgium. The date is three months out, so those of you who want to travel from a distance, or gain support from your institution will have time to get the paperwork in order. Europe and Africa are main regions of interest for our equipment, and we hope this long notice and closer to home workshop will make it easier for many of you to attend rather than travel all the way to Berkeley, CA.

The Belgium workshop will offer multiple project tracks over multiple days similar to the format of the APL workshops in the US. We’ll start with an evening lecture on the science and engineering of gasification, then follow with two days of hands on projects and demos.

The main demo machine will be a 20kw Power Pallet with a turbo charged form of the GM 3.0L engine. The projects during the workshop will focus on work relevant for farming communities. We’ll be converting a diesel tractor to dual fuel gasifier power. We’ll also be welding from scratch a GEK kit in a local metal shop. We plan to locate equipment so that others can build GEKs in parallel.

There’s also lots of interest in gathering European woodgas vehicles for a “show and tell” during the workshop. Dutch John, Werner, Fredrick, Vesa, etc any interest in joining us?

These dates are now final. More details on program and logistics are coming soon. In the interim, if you would like to be put on the list for the workshop, you can write gek or Tom at t.vandeputte.

ALL Power Labs, Berkeley, CA: Feb 3-5, 2012

The next APL workshop is scheduled back to back with the Belgium workshop. We’re hoping these two workshops on somewhat opposite sides of the globe will better serve all who want to see the machinery. Those coming from the Americas and Asia might find it easier to attend the APL workshop rather than the European one. Those coming from Africa, Europe and Middle East will likely find the Belgium one more convenient. However, either workshop is open to attendees from any locale. You choose the locale and program that works best for you.

The APL program will focus on current ideas for deploying the Power Pallet in commercial applications. We are going to finally answer the regular question of “how do we become a dealer/installer of your equipment,” and set out a program for basic training. We will have people report on experiences to date with the equipment, and layout the road map for how things will continue to develop in the months/years ahead. If you would like to present about your GEK project during the workshop, please send us a note.

We’re open to other suggestions for projects and tracks. Tell us what you’d like to see/do/learn at the workshop, and we’ll see if we can make it happen this February.

Workshop Cost: Free if you are a GEK or BEK owner, either through self-build or purchase. Otherwise, $100 per person for the weekend.

Duisburg, Germany: Every 1st and 3rd Thursday

Holger and Kersten of NRG-Consultants continue to offer GEK Power Pallet workshop/demos in Duisburg, Germany every first and third Thursday of the month. These are regular events for Europeans to see the GEK Power Pallet run and try out specific fuels.

Lots of new GEKs

Press print in CAD and GEK parts show up, thanks to the wonders of the local CNC laser cutter house — Seaport Stainless. The pictures above show what 70 GEKs look like as raw parts. This the latest batch of v4.3 GEKs, the batch we’re now at the end of barreling and shipping. (more photos here: http://www.facebook.com/media/set/?set=a.10150330515637611.338107.330512257610&type=3&l=72b498f7c6 )

We believe (though fear to actually say so) that this will finally put us above even on orders for the first time in 3.5 years. We think we’re about to have extra GEKs actually on the shelf, and available for near immediate shipping. To date we’ve made GEKs to order, and often much further behind order than desired. Finally the scaling of our manufacturing process has caught up with our growth needs, at least for the raw kits.

Power Pallets are still a 2-3 month wait from time of payment. The added automation system, engine/genhead, structural elements, plumbing interconnections, accessories and general assembly present a whole new array of challenges — challenges we’ve yet to make as efficient as the raw GEK kits. We’ve learned that making cars is hard, even without the wheels . . .

Here’s all the extra CNC parts that make the Power Pallet beyond the GEK and TOTTI parts shown above. The number of details and accessories beyond the raw gasifier to make a truly usable total biomass power generation system is sobering. The photo below shows 10 Power Pallets worth of accessory sheet metal. Add wires, electronic components, and a few extra hundred lines of BOM, and you get the picture back at the top of the email.

Sheet metal parts for GEKs

Sheet metal parts for GEKs

Power Pallets are currently coming out at a rate of about 5 per month, with 10 per month the goal over the next few months. Groundwork is being laid for much larger throughput. Creative engineers are becoming manufacturing managers (for better or worse). The team is expanding with new manufacturing expertise. We thank all of you who’ve been patience with delays in recent months. We’re working 24/7 to solve it (thus this GEKnews update at 3:35am local pacific time).

Live Webcam on Power Pallet 50hr endurance run

We’re now in the midst of our Father’s Day Gasification workshop at ALL Power Labs in Berkeley, CA.   We have about 75 people here from near and far to wander down the rabbit hole of biomass thermal conversion.

For those of you not able to join us, we have a webcam on the 10 kW Power Pallet endurance run.  You can watch the progress here:  http://www.gekgasifier.com/webcam/

We plan 50 hours over the next several days with datalogging of the wood chip fuel in to power out particulars.  We started yesterday afternoon and ran straight through the night.  So far 24+ hours constant run without issues.  We pulled the filter apart at 24hours and were happy to find it nice and clean.  No bell reduction bell packing either, which has lately been our biggest challenge on long runs.   Some minor tweaks to grate design seems to have cleared up the problem.

We have the full datalogging regime up and running so we should soon have a good set of info on fuel in to power out particulars, as well as system temps, pressures, and gas composition numbers.  The fuel we are using is chipped cedar from the local landscaping supply company.  We’ve sifted out the overs and unders, but otherwise it is standard disk chipper wood chip.  We’re running on average about 3-4kw of electricity generated.

There are lots of good pictures of the workshop proceedings here in Facebook:

June 17-19 Workshop Projects and Schedule

topdownfrontwithjay_img_2042-800-300.jpg

Father’s Day Gasification and Biochar Workshop: June 17-19, 2011

Opening Intro & Lecture: Friday, June 17, 7:30 – 9:30PM
Weekend Build, Run and Test: Saturday and Sunday, June 17-19, 11am – 7pm

Location: ALL Power Labs, 1010 Murray Street, Berkeley CA 94710
Cost: Free if you are a GEK or BEK owner, either through self build or purchase.  Otherwise, $100 for weekend
.
RSVP to the forum here. Buy your spot here.

Our summer workshop is fast approaching-  June 17th – 19th.  Many of you have already RSVP’ed and are flying in from the 4 corners, but there is still room for more.  So come join us for a quality Father’s Day weekend of wrenching, rotating machinery, and guided tour down the rabbit hole of biomass thermal conversion.
The workshop begins with a Friday evening talk on the science of gasification and pyrolysis, and the new engineering solutions embodied in the GEK gasifier and BEK biochar maker.  Saturday and Sunday are full days of building, running and testing the physical particulars. Come prepared to get your hands dirty building and running machinery.  We learn through both talking and working.

We’ll have 4 projects going in parallel for this round of the workshop.  You can participate in all of them, and wander between them as desired.

1.  50 Hour Endurance run of the 10kw Power Pallet:
Long proving runs of the Power Pallet continue on this end.  This round we’ll do a total of 50 hours over several days.  We have it on good authority that it will not rain this time, and we’ll be sure to have plenty of reasonable fuel on hand before we start.  We look forward to more refined data on fuel consumption, gas composition, and feedback on general usability from you kicking the tires over the weekend.  Runs will start on Saturday and continue into the early part of the following week.  If you can’t be here, we’ll have a webcam on the proceedings as usual.

This test will use one of the current generation stainless steel Power Pallets pictured here: http://www.gekgasifier.com/wpgallery/

2. Demonstration runs of the 20kw Power Pallet:
Those of you interested in the larger 20kw Power Pallet will can finally see one in action over the weekend.   There will also be 8 of the 20kw Power Pallets under assembly in the APL factory, so you can see how we make them.  Things will look something like this, only bigger:  http://wiki.gekgasifier.com/w/file/40416596/batch2onthefloor.JPG.  The engineers and builders of these units will be on hand to answer questions and explain the details.

3.  GEK Gasifier Building:
Want to build you own gasifier?  Here’s your chance to do it, using our tools and with plenty of instruction from the local crew.

This round of the workshop we’re having a special GEK Level III building clinic.  We have tables and welders for 4 people who want to weld together a kit over the weekend.  Given clear inhouse instruction, you should be able to get through the building process by the end of Sunday.  Finished gasifiers can Russian doll back into the hopper and filter for checking as oversize baggage on the plane.  Yes this does work.  We do this regularly.

Anyone who wants to do this will need to reserve a spot by purchasing a Level III weld together GEK kit.  There is no additional cost for instruction, using our tools, and burning our welding wire.  The workshop is also free if you get a kit.   We’re trying to make this easy and accessible.

Again, there are ONLY 4 slots for gasifier building.  Welders are limited.  Please reserve ahead of time if you want to build a kit.

4.  BEK Biochar maker running:

We continue to have the BEK on hold while we focus on ramping up the Power Pallet production.  This has made quite a few people unhappy, as there is so few small scale biochar making machines available at the moment.  We’re trying to get back to making these as soon as possible, but in the meantime we wanted to give the interested a chance to run our in house machine.

We’ll have the BEK on fire both Saturday and Sunday of the workshop.  You are welcome to bring your feedstock of interest and run it through.  Or, you can experiment with our variety of feedstocks on location.  If you have some you want to bring, please do write us beforehand so we can coordinate the details.


General Info and Signup

The APL workshop series offers education, research reports and hands-on experience to bring more people to successful operation of small scale gasification and pyrolysis units.  The event is open to everyone, not just GEK or BEK users/owners.  Worshops are free if you own a GEK or BEK by either purchase or DIY build. Otherwise the weekend is $100, which helps to cover food, drink and other consumables.

If you want to join us, please RSVP to the forum thread here: http://www.gekgasifier.com/forums/showthread.php?t=563

A Closer Look At The 2011 Power Pallet

The first edition of the 10kW GEK Power Pallet combined our Tower of Total Thermal Integration with a Kohler v-twin engine. In October of 2010 we began production of the second version, which used a Kubota 3-cylinder industrial spark-fired diesel designed specifically for use with a gaseous fuel, and a Meccalte genhead that could be configured to the requirements of the user’s energy network. This engine, when governed electronically, is stunningly smooth and quiet. Here is a feature-by-feature breakdown of the innovations that have been incorporated into the current Power Pallet line:

Control Panel Mount


Control Panel

The Process Control Unit and Oxygen Sensor readout are mounted in a NEMA box, which in turn sits on a control pedestal at the front of the unit. Also on this pedestal are the on/off switch, hour meter, and keyed ignition.

Stainless Steel Hopper

Stainless Steel Hopper

The biomass hopper is now available in 55-gallon stainless steel with a port window.

Combined Exhaust/Flare Stack With Glow Plug

Exhaust

The engine exhaust and startup flare are mounted on the same stack. A glowplug in the flare automatically ignites it whenever the PCU detects gasification temperatures without engine operation.

Bosch Oxygen Sensor detects exhaust mixture

O2 Sensor

A Bosch Oxygen Sensor detects the mixture in the engine exhaust, and adjusts the air intake servo accordingly.

Custom Air Intake Servo with Air Prefilter

Air Intake

Oxygen is added to the syngas as it enters the engine, to make combustion possible in the cylinder. The ratio is sensed by the O2 sensor in the exhaust, sent to the PCU, which adjusts the air intake servo. Incoming air is prefiltered to prevent a reduction in the downdraft.

Electronic Governor

Governor

The Woodward electronic governor provides robust governing of engine speeds under different load conditions.

Automated Ash Takeout With Grate Shaker

Ash

Ash is extracted via auger. Less than 5% of the biomass volume remains as ash. An eccentric-weight grate shaker engages based on an algorithm that adjusts the period between shaking to clear obstructions if a clog is detected.

APL receives 100kW engine for 100kW GEK

In 2008 ALL Power Labs introduced the Gasifier Experimenter’s Kit, bringing small-scale gasification to the home tinkerer and lab-scale researcher, providing a gasifier that runs common home generators and small vehicles.

In 2010 we introduced the Power Pallet, a complete integrated power system scaled to the common real-world platform of the 4×4 cargo pallet.   It filled the 10kW-20kW niche in the world of biomass gasification.

The natural arc of our development is that we scale our next product to another common vessel, the shipping container.  ALL Power Labs has received the first 100 kilowatt diesel generator that we are are integrating into a shipping container in order to offer a 100kW GEK Power System.  Our clients are the University of Minnesota Morris and the University of Minnesota Twin Cities in cooperation with Cummins Power Generation operating under a DOE grant from the National Energy Technology Laboratory (NETL).  The purpose of this project is twofold:

1) Develop a relevant shipping-container based biomass gasification unit for the U.S. Agricultural market

2) Provide a gasifier mated to a modern diesel engine with precise ignition control in order to experiment with the unique combustion characteristics of syngas.

This unit will include a CHP component.

We have received the 100kW diesel generator that we will be using in our first 100kW GEK.  You may follow the construction and design of this unit here on the GEK website.

Next Workshop Weekend: June 17-19. Update on BEK production

*** FATHER’S DAY GASIFY WITH DAD WORKSHOP ***

Join us at ALL Power Labs June 17th through 19th for our next Gasification and Biochar Workshop in Berkeley CA. This is Father’s Day weekend so we hope you will consider planning a father-and-son/daughter trip to All Power Labs for our workshop.

It has been too long since our last workshop.  Our first quarter 2011 workshop in the Ivory Coast was canceled due to political unrest.   Then we found ourselves too busy building in-house to have one in the spring.  So we’re now giving you lots of notice for our summer workshop.   We also hope to announce some European workshops for later this summer, but dates are still vague at the moment.  We plan to host workshops in Belgium and Italy, corresponding with the delivery of Power Pallets to each location.

The Berkeley workshop will as usual involve multiple projects across many fronts of biomass thermal conversion.  We’ll be doing training sessions and long runs tests of the Power Pallet, biochar production with the BEK, Lister spark conversion, possibly more gas-to-liquids work, and other things not yet known.  I really want to get the gasified Honda running again.  Maybe i can convince the locals to let me take that on.  Details on the program will come later.  When it does, it will look something like this: http://www.gekgasifier.com/about/workshop/ If you are interested in presenting your own project and research during the workshop, as we have done in workshops past, please get in touch.

Worshops are free if you own a GEK or BEK by either purchase or DIY build.  Otherwise the weekend is $100, which helps to cover food, drink and other consumables.  If you want to join us, please RSVP to the forum thread here: http://www.gekgasifier.com/forums/showthread.php?t=563 .  If you need to pay the workshop fee, you can do so via credit card here: http://www.gekgasifier.com/about/workshop/sign-up/

*** UPDATE ON BEK SALES ***

Many have written wanting to buy a BEK and found we’ve paused its production while focusing on the Power Pallet.  We promised an update on BEK production status in early March, so here it is.  The update is we need to continue to pause BEK production for another three months, thus until June 1.  We’ll send another update note then.

It makes us very sad that we cannot well serve your biochar research needs at the moment.  We are simply overwhelmed by interest in the Power Pallets and do not have the bandwidth for both manufacturing projects.

We’re currently expanding our manufacturing operation so we can support higher throughput and a greater diversity of products.  We’ve outgrown our current in-house fabrication methods and are actively building a more scalable solution.  Soon, you’ll see an announcement of job opening to find a new champion of manufacturing to the lead our next stage of growth.

BEK production will start again once we can meet current Power Pallet production needs.  GEK kits continue as usual, as they are a subset of building the Power Pallets.

Two Toms In The Shop

It was a historic day at All Power Labs– we had a visit from the two Toms of biomass thermal conversion. Tom Miles was in the shop getting to know the 10kW Power Pallet for a project in Alaska. Tom Reed was in California visiting his grandson, and decided to stop by to make sure the kids weren’t messing up his hard won work.

Tom Miles is the founder of www.bioenergylists.org and a well-known figure in the biomass and stoves world. Tom Reed’s work at the Biomass Energy Foundation goes back well into the 1970s when he laid the groundwork that most of us learned about gasification from. We were honored to have such forefathers of our industry on site and tickled to watch them fiddle and banter with Bear as they talked theoretical auger angles and increased microscopic surface areas. We hung on Tom Reed’s every word as he described over lunch his hopes in the 70s that someone would develop a functional and inexpensive gasifier generator kit from his research and saw his 30-year wait end as he watched us start up the Power Pallet.

Lab-Scale Fischer Tropsch, Range Fuels Has Issues, Now Live On The Phone 510-845-1500


Fischer Tropsch Progress Report

Jay Hasty and Jon-Richard Little made a nice video explaining the scale-scale Fischer Tropsch reactor Jay is developing. This is a good introduction to the process and some of the (many) issues that need to get solved before it’s a reasonable proposition. No, we haven’t yet made any liquid. But we have made some impressive soot and a bit of methane, though really we’re still working out the many details of set up. Liquid seems not far away.

Even once we have liquid, it is important to remember the distance from demo liquid to something that is realistic to deploy is not trivial. If there is any hole in the ground into which more money has been poured to lesser results than gasification and pyrolysis, it is gas-to-liquids work. Combine them both together, with a good dose of VC “oversight”, and you get something like the recent Range Fuel 300 million dollar hoovering of US taxpayers.

The natives on the gasification list have been having a field day on the autopsy of the Range Fuels corpse. The thread starts here for your entertainment:

http://lists.bioenergylists.org/pipermail/gasification_lists.bioenergylists.org/2011-January/000336.html

Or see Robert Rapier’s perspective in the R Squared Energy Blog on the perils of too much money and too little petrochem industry experience:

http://www.consumerenergyreport.com/2011/01/27/vinod-khosla-and-the-gasificationfermentation-debate/
.

Anyways, back to the point. We’re trying to assess whether small scale GTL will yield to the “expert engineering of everyday junk” stragety, like the basic gasifier proposition has yielded with the GEK project. Some things are better and easier at smaller-scale and with less funding. Some things are harder. The big scale and lots of funding new GTL model isn’t doing too well to date. Maybe we can to better on the other path. Or, maybe we should just import the SASOL folks and let them rebuild their already well worked out solution.

Here’s the basics in video:

New Phone Line with Live Human (510) 845-1500

As most of you know, we’ve been rather challenged keeping up with incoming email and phone traffic on GEK interest. The volume is thankfully much larger than we could have ever expected. We honored so many of you have found this interesting.

Recently we’ve brought on two new people to tend the incoming volume full time- Yoav Palatnik and Jon-Richard Little. Rachael Norman and myself (Jim Mason) still do a good deal of it too, and Jay Hasty continues to do all post delivery support and run advice.

The result is we are now able to keep up in near real time with your notes. We’re caught up enough that we can now have a regular public phone for calls in during business hours. Jon-Richard is tending the phone and is very well versed in Power Pallet application questions and general tech issues.

The APL hotline is now available between 10am – 6am Pacific US time. The number is US (510) 845-1500. You can also find us on Skype at “aplgek”

We’ve also updated our team page. If you’ve ever wondered who’s in the building on the other end of this endeavor, see here:

The Factory Lineup

And finally, here’s what things look like in the factory these days. We continue to make progress on the many fronted challenges of manufacturing the Power Pallets in number.

New Year Power Pallet Upgrades, GEK CHP, Holiday Heat & Power Party

Welcome to the New Year. Here’s what we’ve been up to for the last couple months, and some pointers to what’s coming in the months ahead.

This winter we’ve been deep in Power Pallet refinement in response to user feedback and general product maturation. The upgrades fortunately no longer relate to the core gasifier, but rather to details in the larger Power Pallet control system and integrated product.

The raw gasifier is what always gets the attention, but we’re finding that real usability is achieved (or not) across lots of details elsewhere. Once you get past the early demos and few hour runs, many details of gasifier/engine integration, start/stop procedure, mixture tracking/adjustment, system auto-diagnosis and general fuel/ash handling become central to the user experience. All the early issues of tar fade, and a many-fronted product design challenge begins to emerge.

Sadly, we’ve found the stand-alone gasifier attached to any available engine isn’t really enough. You need an integrated whole with all the parts working together for a regular use, hands off machine. So as we continue our movement towards a “lift lid, put in trash, push button, and out comes useful things” washing machine type experience, here’s some of the details we’ve been working through.

1. New high vac 12vdc blower for start up gas drive- replaces ejector-venturi.

We’ve long wanted to do this, but finding a 12vdc fan/blower with adequate vac (15+ inches of h2o) has proven challenging. We went through another long design process in house to (re)figure out the principles of fan design and make one. Then we finally found a new source with the needed solution, and cheap enough that it’d be silly for us to build it ourselves. The happy result is you no longer need an air compressor on your end to drive the ejector to start your Power Pallet. Also, the GCU controls the blower via an integral PWM, keeping the reactor at the correct pull rate throughout the start up process.

We’ve been able to combine this blower with the existing premixed gas/air flare for continued clean burning. There were some interesting new flame arrestor problems to keep the fire out of the fan, now solved with a simple constriction section.

More details are in the forum:

New DIY Blower tests by Nathaniel

The new “buy it” blower that is better.

Tests to keep the fire from backing up into the blower

2. Combined flare and engine exhaust for single overhead stack.

We decided a flare and engine exhaust integration would be nice to keep operators out of the flare gas on start up. This significantly reduces the potential for someone to make a mistake and get in the CO, and just generally improves air quality around the Power Pallet. The resulting combined flare/exhaust stack also has a 12vdc hot element lighter so a propane torch is no longer needed. The flare auto lights as soon as there is flammable gas.

The flare / engine exhaust integration is also the intended foundation for our future CHP plans. We want a CHP solution that allows for varying ratios of heat to electricity, which requires being able to run the flare in parallel with the engine, and have both heat sources go to the same heat exchanger. With both the flare and exhaust going to the same heat exchanger, we can run each independently, or together, or in any combination desired. More on CHP plans below.

The details on the flare/exhaust integration are here: http://gekgasifier.com/forums/showthread.php?t=501

3. GEK CHP (combined heat and power)

We’re working towards a native CHP system built standard into the Power Pallet. The goal is to make available both the hot water from the engine cooling system as well as the hot exhaust after the pyrocoil towards off-board heating needs. We’re working on liquid heat exchangers to produce hot water for heating and hot shower water. We’re also working on hot gas-to-gas exchangers so you can get hot air for fuel drying and agricultural crop drying.

There are many fancy ways to do this. Bear will document those later. There are also some cheap obtainium ways to do it with stuff laying around the homestead. Here’s some tests we did recently on both fronts. The results now runs our local hot tube, pictures of which are at the end of this post.

4. New gas/air mixing servo butterfly valve

The one we’ve been making in-house has worked well, but its longevity is under debate. We decided to get a custom one made at the small orifice size needed. There are not regular sources for the small size servo butterfly we need, at tolerable prices. Now we’re having some custom made overseas. They’ll soon be available for your own DIY projects too.

5. Electronic governor to replace mechanical governor

Mechanical governors are robust, but we’re unsatisfied with their speed accuracy. It seems to be the nature of the mechanical governor beast, thus we’re going electronic. The mechanical governor will continue to be there for a backup if needed.

6. Grate shaking and ash auger.

These systems continue to refine to better purge bell packing with finer fuels. The latest round of changes creates a bit of upward grate movement while shaking which significantly improves fines purging. Adding an upward movement to the shake is surprisingly effective, and it has was interesting to learn the historic Imbert gasifier did this too. (thank you Deutsches Museum)

Holiday Heat and Power Party

Seeing that the above improvements cumulatively produce lots of hot water, we decided to have a party. Thus our company holiday event this year was the “Heat and Power Party”. The Power Pallet lit the event, made gas to cook the crepes, and heated the hot tub water to stew the humans. Other fire assemblies appeared (as usual), Kimric shot the monkey cannon at all non-moving targets, and someone brought a very tasty chocolate cake that I ate a good deal of. The building was still full when I left, and some were still there in the morning. A successful CHP event– hopefully the first of many.

Here’s the photo set from the party: http://www.gekgasifier.com/gallery/browseimages.php?c=49


More news soon. In the meantime, I hope you will keep up with our progress by visiting the GEK forum. We’re there every day. Come and join us: http://gekgasifier.com/forums/index.php
