Thanks, Bruce, for your comments. I went for a ride today, so here is an update.
For some time I had been envious of Don Mannes’ 3 miles-per-pound results with his Tracker. For a while it seemed that I was getting further away from that “record.” Our engines are the same size, but mine is older and has a carburetor. After replacing my spark plugs recently, I suddenly got a boost from under 2 miles per pound to 2.6 miles per pound for a 27 mile trip which included some “highway” and “city” driving. So, early today, I took off through the country for some genuine “highway” driving at 40-50 mph mostly, and the results are in—8.5 pounds for 26 miles which calculates to barely over 3 miles per pound. I used about 2 drips a second of water and some exhaust gas. The car is rated for 28 miles per gallon for “highway” driving so the gallon to pound calculation comes to 9.15 pounds charcoal to one gallon of gasoline. I’m OK with that.
Tom, I think removing the trunk lid is keeping the gasifier cooler. When I got home, the reactor lid thermometer was showing under 200 degrees F, the gas exiting the filters was about 100 degrees F.
It ran quite well with good power, but sometimes it is a bit weak starting off. If I can keep moving, it seems to run quite well. I’m very pleased with the results.
My children are treating me to dinner at the Cracker Barrel tomorrow. I love their biscuits. Happy Father’s Day to you all.
