We just started the Power Pallet a few minutes ago.
The webcam is back online at gekgasifier.com/webcam.
Ustream had an outage yesterday, but we put in a nice smooth ~8 hour run in. I'll post datalogs as time allows.
Cheers,
Bear

Hello APL!
Did you change out that air/oxygen valve to a smaller one Bear? and how's the grate shaking code coming? Have you made more adjustments since last weekend?
It also looks like you've got a hose hooked up to the final engine exhaust out?
Looking forward to hearing more details,
Keep up the good work!

Hi Tom,
The valve is the same. It could probably use to be a little smaller for better resolution, but we've been holding mixture pretty constant with this setup.
I needed to slightly adjust the PID because the original values created a bit of a harmonic in the system, that would cycle the mixture/governor slightly over ~5 minutes. PID adjustments cleared that up.
We installed an ash takeoff. There are a few mods to do to it, but it's working.
Yes, we were hooking up a wierd contraption to the exhaust. The chips come in very moist (~100% moisture content on a dry basis, which means 50% of the wet chip mass is water). So, we were experimenting with preheating air with exhaust heat to dry the chips.

Bear
