AN ENERGY OPTIMIST-The Brown Mound At 117 Degrees
Submitted by Gaelan Brown on Thu, 10/08/2009 - 11:27am.
During the past week the water coming from the 400-feet coil inside the "Brown's Mound" has increased in temp from 95 degrees to 117 degrees. The temp seems to stay steady unless I increase the flow-rate beyond 1 gallon per minute.

Exciting news...we're now at 120 degrees and rising, even though it was 28 degrees outside Sunday when I checked. Still holds steady at 1 gallon per minute. Trench-plumbing being done this week.

Hi.
I saw your video on Youtube and I'm veeery interested in finding out how the project is progressing.
Just so you know a bit about me, I'm a Goat dairy farmer/cheesemaker in the mountains of Japan.
There is constantly forestry work going on around here, and I'm hoping to get an experimental mound started before the end of the year.
How's the methane going?
Any luck?
Thanks for the video and thanks for your time.
Rob Alexander.
Thanks for your reply.
I wonder if a displacement system might not be a more practical choice than the "sump in a tank" system for biogas production.
Essentially a large bore PVC pipe placed horizontally (well, on a slight angle) through the mound.
Adding and removing material would be dramatically simplified and the heat profile of the mound might also support the 2 different methane producing temperature zones (if we're really lucky).

Western Washington University is doing some well funded research into methane production and refinement from biodigester sources for their "Viking 32" vehicle project.
More power to you.
