With such a "beans to BTUs" scheme I'd be slightly worried about the gas being introduced to the appliance being itself already a combustible mixture, with possible "blowback" consequences that I shudder to contemplate. Then again, an appropriately sized and located flame arrestor would minimize that ...

Methane is  important from both a GHG  and energy source perspective.  Currently, a lot of it is vented or flared.  Much of the methane emissions (primary component in natural gas) come from petroleum production. But any human activity that sends organic material into an anaerobic environment  makes ...

There's plenty of current instances of methane recovery from cattle farms and landfills, among others.   https://www.epa.gov/lmop https://www.epa.gov/sites/production/files/2018-06/documents/epa430r18006agstarmarketreport2018.pdf ------------------------------ Patrick Jennings Repair Development ...

I don't know much about lightening or cars but I know about airplanes. They are often struck by lightening. There are various design features and gadgets employed to protect them. Perhaps you can find a parallel for cars. Boeing's AERO magazine published a good article about it; you can find it here ...

"... flash of light with immediate thunder and I felt a surge of electricity through my right leg..." Were you driving through Roswell, NM? On a serious note, lightning strikes airplanes all the time and many passenger never even notice. ------------------------------ Laurence Evans Account ...

Another 19th century idea: Cities like London used to run street lights off of sewer gas. The combination of methane and other more noxious gases lit up streets, although varying gas composition often made them unreliable and they were replaced with electric lamps. https://www.atlasobscura.com/places/carting-lane-sewer-gas-lamp ...
