It appears that most of problems were related to the characteristics of ga and not the tteck. They had failure rate problems, inability to stack with ga, toxic emissions among other things. Do not get me wrong in that am totally convinced in poet teck but just wondering if the problem may b ga. What has been achieved to eliminate the earlier problems with ga. Could it b that the market may b reluctant to adopt poet because of prior problems in using ga?? I would appreciate it if someone might dispel my concerns!!!! Thanks
