| | Jerry - So when are you likely to go there ? One of my coworkers recently spent a couple of months there (their summer / our winter), with the National Guard. I believe they said the temp. was a balmy 20 deg. or so. So - would you be there just in time for winter ? (There's a thought - 5 months in a hut, in the dark, with Jerry. Can anyone say " cabin fever" ?). |

| | Sorry to rain on the parade, the alternative to propane would be Natural gas for pilot. Biogas may not be able to ignite or sustain a flame without a good quality gas source with it. An electrical heating element just isn't going to cut it under all operating conditions. From an environmental standpoint, unburned methane in the biogas has a 23 fold larger carbon footprint than the carbon dioxide by product. |

| | John/Victor The person who spent a winter in a cabin with me would become a very religeous person. He/she would be using a lot of Rev Wright language at the end of the term. Anyway that job doesn't start until August. I'm working on something in Missouri right now. |

| Some companies are making flares with biogas pilots. It is well understood that the gas may be moist and unreliable...but you would only be flaring if you had TOO MUCH biogas. With some of the new ignition systems, it appears that they can ignite a biogas pilot and use that to ignite the full flare. If memory serves, Varec has a model that allows this. Another can be found here: http://www.paques.nl/?pid=59
Of course, this would be done on a case-by-case basis, however, it doesn't seem to make sense to pay for an additional LPG pilot source when biogas would be readily available. Perhaps a temporary source is used at startup to ensure the pilot burns. Once the digester gas gets "rich" enough with methane, the biogas could be used for pilot as well. |

| | The problem I see is if you get a brief interruption in gas, both the flare and the pilot go out. You need an independent source of ignition be it LPG, natural gas or a big spark plug. |
