How long would the motor have run on the gas you used to heat the retort?

This seems like a false economy to me.

@ozzirt You are correct. However a more developed system will use an oil burner to heat more plastic and use oil from that process.

Our 3.5 horse Briggs and Stratton engine ran 15 minutes on a single milk jug! There is lots of energy in HDPE. I have yet to post our latest video, but we were able to actually produce GASOLINE with a secondary vaporizer.

I have seen your woodgas videos and have learned from them, thanks, DREW

Tomorrow we begin work on a full size plastic vaporizer for a car. We are struggling with a system to feed plastic in a consistent flow. Batch process causes a range of performance and long start up time. Thanks for you kind comments. DREW

most plastics have around 12 to 15,000 btus per pound thats much higher than most woods just be careful of chlorinated plastics I'm currently building a system to turn 250 tons a day of auto fluff into electricity thats about 14mw of power so keep up the imaginative thinking

Very Cool! ;0)

try using cigarette butts for your sealings

that is the most incrediable thing i have ever seen.  I dont know wether to be impressed or horrified at the plastic smoke pollotion. So if i was really stuck i could magiver plastic trash to fuel just by heating it? Talk about a madmax solution.

Next run the smoke over a water bed in the bottom of a 30 gal drum filled above the water with straw for fine filtering. A heavy grate keeps the hay off the water.

The really critical part is a hot enuff hearth to crack the tars in the first place.

Very interesting vids. Keep up the good work!

[ornottoobless]

I believe your retort temperature is not hot enough to crack the tars and they travel with smoke and get deposited inside the engine. Having done some gasification experiments i would suggest you add a cyclone after the retort, then cool the gas with a heat exchanger and finally filter the gas through a deep bed of straw before it enters the carb. The cyclone will remove some particulate matter and H2O and needs a removable condensate trap(container). The cooler will need a trap also.

can futher explain how GASOLINE is made with a secondary vaporizer?

Hey not bad!
