Do you smell hair burning?
I spent some time last weekend trying to test out my gasifier. It didn't take much work to get it fired up and running but it was not running all that well. I had a major tar issue and not enough vacuum from the furnace inducer motor I tried. After fifteen minutes or so the temperature spiked and the flame went out. I knew it was bridged up but wasn't too sure how to go about breaking it. I turned off the motor and opened the top. With a three foot stick I started to jab at the wood. About the fourth jab she let loose with a mushroom cloud of flame and I had my arm and face right in there.
It's not the the first time I've had things blow up in my face but it has been a long time since the last time. I thought I was getting smarter but I guess it was just luck. "play with fire and you'll get burned" is what my mother would say when I came home with no eye brows/hair. After contemplating what I had done and a little thinking I lit it back up and had a flare for an hour but found I needed to do some more work before I could test it some more.
The flame should be almost invisible during the day, not orange like this. I'm producing too much tar do the fire not being hot enough. I'll need to find a better fan and make a couple modifications before another test. I'll do my best to keep the rest of my hair.

wood gasifier
For the last month I have been building a wood gasifier for my truck. The technology has been around for over a hundred years. With gasoline prices going through the roof, I figured I could build one in my spare time, out of junk and drive for next to free if it all works out. So far it is almost ready for a test fire but I have yet to build the secondary fine filter. Wood gasification was enhanced during the second world war when the fuel embargos/shortages were in Europe. Thousands of vehicles were switched over and the design is generally the same as today. There are very few people running wood in north america.
The process is simple. Control the air to a hot fire, pipe the incomplete combustion gasses to the motor and control the air mixture as it enters. The gasses produced for the purpose of combustion are hydrogen, carbon monoxide and some methane. The power of the motor is cut to 75% or so do to the lower btu content compared to gasoline but the price is right. Its all experimental build your own at this point. My gasifier should be able to burn any biomass with some modifications but the design is for small wood chunks/chips.
If your interested in the design/concept. Google "woodgas" "holzgas" or "gengas" and check it out. There is a large group of experimenters on Yahoo groups they post trials and tribulations of thier work.
You will see more posting of my work on this as the flying season ends.

Home!
When the forecast went to the crapper I went to Creston for some visiting and flying. I finally got to fly down to just about the border on Mount Thompson and got some wonderful views of "home". I would post them but my camera died midpic and I got squat. Trust me though, it was awesome!

Windy in the Lz prompted us to delay pilot meetings a few times and then call one late up on the mountain. It was no better there and the day was called. A few diehards flew and I wanted to get Cal his first thermal flight. We waited till the wind died and soon he was in the air. I quickly got suited up and followed to try and guide him. To my surprise he was thermaling up the spine and higher than launch when I launched. I climbed up over the peak to see him, Tim, Leaf, and Rob all sharing the sky at the top of the mountain. Your first high flight is great but there’s nothing like your first thermaling flight. I flew for an hour and landed early to catch his landing on video. He flew for an hour and a half and was ecstatic when he arrived on the ground.

The day was forecasted to blow in ugly stuff from the north so we called a task to Invermere. While setting up we could see the dark clouds advancing and were all trying to get off fast but the pilots in the air were not finding any lift. I was all suited up and jockeying for position when I heard over the radio that the LZ was very windy and turbulent. The gust front had arrived and with no lift it was likely to land there. I bagged it and drove down. We got hit by thunder storms soon after.

Practice day
I broke a few personal bests on Saturday. I flew just about Edgwater, and 2.75 hrs in the air. It was a very rough day but as soon as you were above the peaks the thermals smoothed off and became coherent. I had no problems the entire way. Doug and John made it to Invermere and rob was a few Km farther than me.

Nats start
It was rough. Didn’t matter where you were in the sky. The task was to Brisco and back. Lots of people bombed out early. I struggled in a gaggle over launch, not getting very high, till I got tired and ventured to the spine. I was rewarded with a good climb and was soon over the mountain with enough height to cross the gap. I was fighting a head wind and knew I would not make the peak, luckily I found a good strong thermal half way through the gap and just when I thought it was good smooth lift I went negative by a foot and was slammed back down. I screamed like a school girl and then looked around to make sure no one heard me. I was alone. Made the next peak easy but nobody was following me. I wasn’t feeling too good from the night before and long flight, so I turned around and headed for the landing field. Flew for an hour and a half. Scott won the day with John just behind. Everyone landed at the LZ either making goal or bombing out.

Also stay tuned for my next project in the making.... I'm going to convert my truck to run on wood! I'll start on this when I get back hopefully.
