I should add that this might be an approach to drastically reducing natural gas flares:
http://www.stoptheflares.org/ What is needed at the flare sites is a way of shipping the energy where it is needed but these sites tend to be remote and pipelines to them tend to be expensive given the expected lifetime of a particular well being flared. Small scale NG liquefaction can be expensive, so LNG transport isn't very viable either. The potentially small scale of one of these LKT generators might make electricity a viable energy vector for those isolated sites. It would probably require some innovation in rapid deployment and redeployment of high voltage power lines.
