"What a wonderful piece of kit - no idea why it is called experimental - works like a charm - stunning !! I had it on flare mode for two 30 minute periods the other day with perfectly clean gas. My compressor was a bit small so I used two 15 litre aqualungs to beef out the compressor. I was pulling on average 2 on the water gauge. I was using perfectly dry 1 to 2 inch cubes of larch. Larch generally has loads of tar so surprised at the clean burn. I eventually got to around 8-900 degrees Celsius - not sure if I have the probe all the way into the top unit.
I had a white T shirt on the top of the filter (wet out with oil) and it had marginal amounts of tar on it ( the filter was half full because I could not get enough charcoal as none of the shops had it.) The filter was very wet on the inside though - I assume mostly condensation as it was just above freezing outside. Only problem was it was too close to the house and stank out the lounge and upset my wife a bit.
I had the generator delivered - a 20 hp Honda V6 with 10 KW generator (exactly the same as the one you have on the video). I have an engineer who will put it on a pallet for me connecting the exhaust to the pyrocoil et al. I will install it into a container with flare and exhaust externally vented, air intake from the floor of the container with a hatch in the top of the container to vent heat and a couple of large fans to blow all the air around to keep the engine cool and vent the nasties. The wood will also be stored within the container for drying using the heat of the Totti.
I have not assembled the whole kit yet so may have to come back for advice once my engineer gets his teeth into it.
I will be getting my band saw out this weekend so will be cutting some larch for the shed as well as cubes (1/2/3 inch) of larch, chestnut and ash for the totti as I want to experiment with different woods. To this end is there as way of putting the feed hopper directly on top of the pyrocoil - not sure if you need an adaptor.
I also making charcoal in a 45 gallon drum for the filter. Buying in a ton or so of hardwood fuel grade woodchips as well
All in all I am very pleased - the bigger generator allows me to use 4 power tools now so my barn workforce is now very productive, as they can all use a power tool at the same time - can't wait to convert to gas to save on the expensive petrol cost which is $ 9.00 a gallon.
Have not got it all thought through yet, as I am erecting my timber frame barn over the next three weeks so busy with that.
Will keep you posted.
